Application thread typo3 could not be started. What is TYPO3 and what is it eaten with? What is TYPO3

Distributed by free license and with open source code which makes it even more practical and versatile. Today, TYPO3 sites are becoming more and more popular.

TYPO3 is written in PHP and works equally well with most common databases including MySQL, Oracle Database and many more. In addition, the platform works with all major operating systems and popular servers.

The author of the project is Kasper Skarhoyem, who sought to create a high-quality and reliable CMS that can compete with commercial platforms. TYPO3 has a user-friendly interface and an intuitive admin panel. Numerous modules and extensions allow you to implement projects of any complexity and purpose.

Currently running on TYPO3 over half a million sites around the world, including portals of well-known companies and organizations. Among them are UNESCO, Cisco, Epson Corporation, as well as most of the official pages of OAO Gazprom and a number of subsidiaries.

Kernel development two teams are involved, which conditionally divided the project into two branches. TYPO3 and plugins are created by thousands of independent developers and third party companies.

The system works with tree structure pages. Each contains its own content, which is divided into small information blocks. It can be text, images, tables, widgets and other elements.

Registration built on the principle of templates, typo3 fluid is used for this. Most of them are written in TypoScript, a special configuration language developed for this project.

Like many other CMS typo3 uses two standard modes of operation:

• front end- the external interface of the site typo3, which is seen by visitors, his face;
• backend- interface for administrators and editors, which is used to manage the site.

Also TYPO3 supports the possibility direct editing, which does not require you to go to the control panel. Edits can be made directly from the page while viewing it.

cms featuresTYPO3

Before downloading TYPO3, please read core capabilities offered by this system. This is a comprehensive and balanced solution that allows you to work with sites of different levels.

• tree structure

  This applies to both pages and folders in the admin interface. Such an organization is universal, practical, and also understandable to users who are accustomed to working with a similar structure of operating systems.

• Content Elements

  The number of functional elements on a page can vary widely. This includes both building blocks and special TYPO3 plugins, the installation of which extends the basic functionality.

• Extensions

  A huge number of extensions are on the web and are installed directly through the panel in just a few. In the absence of the required plugin, you can develop it yourself, but for this it is better to study the TYPO3 tutorial and supporting documentation in advance. Some blocks affect the appearance of the page, others are necessary only for the administrator and are not visible to visitors, others combine these features, providing an integrated approach.

• Multilingualism

  The admin panel is available in dozens of languages, including TYPO3 Russian. You can also choose multilingual content for the content, while maintaining the site structure in its original form, or vice versa - using independent structures for each language.

• Scalability

  The system works equally effectively with small sites and minimal traffic or portals with tens of thousands of registrations and visits. To support this feature, modern caching tools are used, including caching pages to static files.

• Multisite

  TYPO3 allows you to manage multiple projects at once through one web interface. Different sites may share common content or not overlap at all, as well as differ in settings, use different TYPO3 templates and have unique permission settings. In the panel, they are presented in the form of a single tree structure.

• Wcovered sections

  CMS typo3 supports the extranet principle by providing a special registration system for partners, clients and sections for them.

• History of changes

  This block allows you to control all the changes made, track the work of editors and undo the changes that were made by mistake, or the result of which did not satisfy the task. A clipboard and a preview of the result before publishing are also available.

• Multi-user editing

  The typo3 site can be edited by a full team of specialists with different access rights, which are set by the administrator.

• TypoScript

  TypoScript is not an independent programming language, but is used to set up TYPO3 configurations. It allows you to set constants and prescribe conditions, changing the presentation and content of pages. All elements and details are written into a single array, which is accessed during operation and rendering.

• Design flexibility

  Sites on TYPO3 can be both strict corporate and non-standard creative projects. The system supports integration with a variety of templates that differ not only in style, but also in construction. In addition, separate templates can be used for all major functional elements.

• Templavoila

  An alternative templating engine for TYPO3, with which you can convert html templates without changing the structure. The conversion process is based on matching code areas and related functionality. To perform the procedure, you do not need development and programming skills, and even knowledge of HTML, all static and dynamic components are created in a few clicks.

• Working with images

  Images are a separate content element that has flexible placement and display settings. This allows you to combine text content with full-fledged galleries by setting rows, adjusting scaling and using additional processing tools. TYPO3 provides a separate editor for this with a fairly wide range of functionality.

• Linking
• Formats and standards

  TYPO3 Russian supports different formats and standards. The system works with WML and XML, allows you to export data to PDF or static HTML. RSS export and import are supported separately.

• visual editing

Now the visual editing function is provided in most CMS, but in TYPO3 the possibilities of such a visual editor are wider and more diverse. The following features are separately supported:

• Inserting links with their subsequent saving when changing the structure of the site;
• Removing unnecessary tags from texts;
• Automatic scaling of images and their insertion;
• Converting html tags to the required format;
• Full editing of tables;
• Customization of functions and buttons.

• Menu

  The CMS menu is located on the left. It is through it that the necessary functions are selected and launched. Sometimes you need to additionally select a page in the structural tree.

• work area

  The workspace for making all changes is on the right. Texts, images, data and other materials are entered here. If the menu remains stable, then the space changes depending on the selected page.

As already mentioned, the TYPO3 installation is extensible with additional plugins. Among popular solutions:

• Flexible news feed;
• Forums with registration, sections and subsections;
• Integration with existing forums;
• Integration with search engines for indexing pages and organizing an internal search module;
• Visual editing links for images;
• Calendars;
• Chats and blogs;
• Directories for ;
• Editable user forms;
• Commenting, typo3 reviews, voting and guest books;
• Image galleries;
• File archives with a strict structure and categorization;
• Reference blocks and tutorial TYPO3 org;
• Modules for and optimization.

You can conduct a thorough analysis of your site online. How to do it right, you will learn by reading.

Why chooseTYPO3?

TYPO3 positions itself as high quality and safe system, the first development of which began in 1998. Gradually, the project became a kind of brand of success, having won many fans around the world. Gradually, more and more new versions appear, but why do users prefer TYPO3 with all the diversity of the market?

• The system is used by many successful commercial sites, including well-known organizations and enterprises. This clearly illustrates its reliability and user friendliness.
• The CMS guarantees support for a dynamic menu that features a bright, eye-catching and modern marketplace.
• Any average user can get comfortable with CMS management, so downloading TYPO3, installing the platform and putting it into operation will not be difficult.
• When editing or adding content, the page design is automatically updated.
• The system is constantly evolving, which is being worked on not only by developers, but also by numerous third-party enterprises and enthusiasts.
• High-quality documentation is attached to the open source, so that all extensions can be connected without any problems.
• TYPO3 has moderate requirements for maintenance and service, due to which it is relatively unpretentious.
• The possibility of multi-user access allows you not to depend on one programmer, rationally distributing the management and editing of the site.

At the same time, it is worth paying attention to the fact that experts not recommended to useTYPO3 in the following cases:

• With a minimum budget
• If you do not want to learn and train editors;
• If desired, actively replenish the site with content from visitors;
• When creating a built-in store;
• If necessary, in the built-in ;
• Too few or too many pages (less than twenty or more than five thousand or so).

However, such contraindications are easy to deal with if you have the desire and some skills in working with control systems.

InstallationTYPO3

First of all, it is necessary downloadTYPO3 from the site and call the installer program, which starts automatically. After that, the system will prompt you to familiarize yourself with the basic information data, as well as set a login and password.

The second step is the choice Database or creating a new one. You need to import the CMS installation tables into the database and continue the process. Further work will be performed automatically, after which the installer will congratulate you on successful completion.

The third step is to choose one of three options:

• TYPO3 setup;
• site preview;
• Registration in the admin panel.

To provide security The CMS provides a number of tips that the user is advised to follow. Immediately after that, you can proceed to create your own website.

Sincerely, Nastya Chekhova

Free content management system (CMS/CMF) with open source and free license. Written in PHP, uses MySQL for data storage.
According to many people, TYPO is considered one of the most powerful and reliable CMS, even though it is free. Even several Swiss banks and some European payment system use it.

After reading high statements about this CMS, I decided to personally test it.

The system requirements for TYPO3 turned out to be very high. The developers advise to use a dedicated server that is not overloaded, since regular hosting will not work.

It didn't even want to be installed on my home server, despite the fact that my server met all the requirements of TYPO3. The installation always died at the stage of creating tables in the database.
After that, I decided to try it out on hosting (godaddy).
She successfully got up on hosting and I started testing her.
At first glance, everything seems to be clear, but when you start using it, you are faced with a misunderstanding of how to work with this TYPO3, how to add news, how to create something.
Everything is not at all obvious and before working with it you need to study the manuals.
For example, there is a Russian language for TYPO3, but I could not install it without the help of the wiki. It's just not clear how to stick it into this CMS.
It turned out that in order to change the language of the admin interface, you need to go to the module Ext Manager, then select the menu translation handling, different languages ​​should appear here, loaded from the TYPO3 website, select the Russian language, click on the button, after that you will need to click on another button update from repository. These manipulations are called "loading the language from the repository". After this loading from the repository, you need to go to the module user, Further Setup and here already choose the Russian language and then the admin panel will be in Russian.

Working with modules also turned out to be far from easy.
I decided to check how the modules are installed.
TYPO has a number of modules (extensions) already loaded into the system, but I wanted to install another module, downloaded some catalog module from the TYPO website and installed it, it appeared in the list of extensions, I turned it on, but nowhere in the admin panel named.
I did not find any new menu item.
After that, I decided to install the extension of the online store.
But after installation, all this TYPO just fell off. There are errors in the admin. The site itself works, but there is no admin panel, only PHP errors are visible instead of the admin panel.
I could not do anything with this, I finished testing on this.
Most likely, the hosting settings did not fit (Safe_mode ON), since the extensions created folders during installation and probably tried to write something in them, and in Safe_mode ON mode, creating folders is useless, probably for this reason the entire CMS has crashed.

My conclusion!
Based on the results of my unsuccessful testing, I can only draw one conclusion.
The system really requires huge resources and will feel good only on a powerful, not overloaded server, ordinary hosting for TYPO will not be enough.

Hardware and software requirements

PHP version: 5.2.x-5.3.x
PHP as an Apache module or in CGI mode.
G.D.
ImageMagic (or GraphicsMagick).
The use of exec in PHP should be allowed.
MySQL version 5.0.x-5.1.x.
There should be no limit on the number of requests per hour to the MySQL database.
RAM - 1 Gb of server memory on all hostings is now available. Installing TYPO3 on a machine with 512 mb RAM is possible, but not recommended.
PHP memory_limit - 48MB
Register_Globals off.
Safe_Mode off.

Developer comments about hosting for TYPO3

The hoster must not have a loaded server. That is, 300 accounts on the server is not suitable. And this is exactly what most hosters have (sometimes even up to 500 accounts).

Hostings cheaper than $10 per month are not suitable.
On such cheap hostings, only static sites or very simple systems work normally (and then usually until the hoster hangs 400 accounts on the server).
There are separate examples of using TYPO3 on cheap hostings. However, most likely, this is a temporary success - until the hoster has loaded its server with several hundred accounts.
Many aspiring web developers don't have an understanding of the hosting business, which is why there's so much discussion about which host is the best, and so many jumps from one host to another in this lower price range. If your hosting budget is less than $10/month, then TYPO3 is definitely not worth messing with as you will end up with a constant headache. You need to either find a way to increase this budget, or choose another system.

Story

The history of TYPO3 CMS dates back to 1997-98, the author of the system is Kasper Skårhøj (Kasper Skorhøy). Distribution - license GNU GPL (free software). Technologies - PHP and MySQL (but supports Oracle Database, PostgreSQL and other DBMS); works on popular servers and operating systems (Linux, Microsoft Windows, FreeBSD and other operating systems).

Fame came to TYPO3 CMS after the release of the third version; the current one is 8.7.4, released on July 25, 2017 (documentation).

TYPO3 is both a CMS (that is, a content management system) and a CMF (that is, a framework that can be used to create your own content management system). The decision to use TYPO3 as CMF allows developers to make, firstly, a more convenient admin panel, and secondly, a more lightweight site as a whole (because only the necessary functions will be used).

In short, TypoScript is a special language designed to customize websites and design them. It's not a programming language. Here it is also important to define that a template in TYPO3 CMS is not just a template that defines the content of the page displayed on the site, but also a TypoScript template that can then be used to create other pages.

By the way, you can use TemplaVoila to create templates! - template engine with which you can turn an HTML template into a TYPO3 template. It is important that this extension has the ability to create dynamic content elements, which allows you to flexibly manage the content of the site.

Why is TYPO3 CMS better than other engines?

This question itself is too provocative to ask, but users are always wondering - why should I use this particular platform and not WordPress (Joomla! etc.)?

TYPO3 CMS is a good platform for a medium to large project, site where flexibility and extensibility is important. Of course, the flexibility of the engine translates into the fact that a competent specialist should work with it, who will be able to understand the settings system and understand how TypoScript works.

If you are a customer (or just wondering what to create a site on), then TYPO3 CMS is right for you if:

• you have a medium or large budget for creating a website;
• your site is not an online store or a social network;
• the number of pages will be approximately average (not small - 10-20, but not large - 5-6 thousand);
• you will not use the built-in CRM.

This does not mean that it is impossible to implement what was written above on TYPO3; this means that the implementation will be problematic, so it is easier to take some other, more suitable CMS.

To sum up, TYPO3 is perfect for mid-sized companies.

Extensions

Extensions are plugins that can be selected in TER and then installed via the TYPO3 CMS using the Extension Manager in the menu. TER - TYPO3 Extension Repository (TYPO3 extension repository) and it is located . This is the official collection of extensions for TYPO3.

As in other CMS, extensions here have very different functionality: some of them affect only the appearance of pages, others are responsible for internal features; a large part affects the internal and external sides of the site (talking about news, galleries, etc.). You will also have a lot of scope for customizing these extensions.

Installation

As already mentioned, on Timeweb you can install the engine directly from the control panel; in other cases, you will have to use the official instructions: https://typo3.org/download/

After installation, the admin panel is available at: Website address /typo3/

A separate feature of TYPO3 CMS is the presence of two interface areas, internal and external. The first is responsible for site management, editing; the second is the interface that is generated and displayed on the site, it is available to all visitors.

The administrative part may seem a little more complicated than in other CMS. To work with TYPO3 CMS, it is desirable to have experience in site administration and creation. However, for ordinary, simple actions, deep programming knowledge is not required - everything can be done from the control panel.

In this article I will try to tell you what TYPO3 is, what advantages and disadvantages this CMS has, how TYPO3 differs from other CMS and what its scope is. This article is most likely for those who have never worked with TYPO3 before. I have no doubt that there are people on Habré with more experience than I have, and I hope that they will correct me if I'm wrong somewhere.

What is TYPO3

TYPO3 positions itself as a content management system for the enterprise. The development of this system was started by Kasper Skårhøj back in 1998. CMS is distributed free of charge under the GNU GPL license, written in PHP using the MySQL DBMS (theoretically supports others). TYPO3 became a brand after the commercial success of the third version. The version number jumped to four a long time ago, but the three in the title has remained so since then. The current version is TYPO3 4.6.0.

Why is TYPO3 better than Drupal, Joomla or %CMS%?

In fact, comparing these systems with each other is a thankless task, since they occupy different market niches. For example, Drupal is much better for sites where visitors are expected to participate in content creation. In Joomla, the editor will be able to quickly figure out how to format the text correctly. Why then do you need TYPO3? Like any CMS, TYPO3 has its advantages and disadvantages. The advantages include flexible configuration of user rights, the ability to use one installation for several independent sites and domains, the ability to use extensions from TER (TYPO3 extension repository) and versioning. The main disadvantages are the complexity of editing, a complex system of options and settings, slow rendering of large pages. One of the main features of TYPO3 - typescript - is a double-edged sword. On the one hand, most of the settings can be changed without getting into the PHP code of the CMS or its extensions, which makes it easier to update the system. On the other hand, you need to learn the typoscript (syntax and basic "options"), in addition, when setting up extensions, the horror begins with smoking manuals (if any) since the names of options for extensions are limited only by the developer's imagination. It is contraindicated to take TYPO3 if:

• the customer has a small budget
• the customer wants a portal with content from visitors
• need a built-in online store
• the customer does not want to teach editors
• the site has less than 20 or more than 5000 pages
• the customer needs a built-in CRM / the customer wants his CRM to work with the site

Naturally, with the help of a large file and straight arms, these contraindications can be overcome, but it is worth considering whether it is easier to take something else. The ideal niche for using TYPO3 is the websites of small and medium sized companies.

Extensions, extensions...

Plugins are called extensions in TYPO3. A bunch of these extensions can be found in TER and installed directly through TYPO3. If the required extension is not available, then you can write it yourself. To do this, it is recommended to read the TYPO3 API documentation, otherwise the result will be quite deplorable. The extensions themselves come in every taste and color. We will see some directly on our page (for example, forms or flash movies), others will expand the capabilities of the system (for example, using a database to save pictures) and will not be visible to the visitor, most of the extensions will do both - the content is shown to the visitor and you are given tools to customize this content (news, image galleries, etc.).

TypoScript

TypoScript is not a programming language, it is used only for configuration and is purely declarative. One of the most important features of TypoScript is the ability to write conditions and define constants. On large pages, depending on which branch of the site a certain page is located, for example, the number of columns changes. It is logical to use a condition for this, and in a constant you can write the internal ID of the page from which the branch begins. TypoScript is also used to configure extensions (for example, you can set the number of shown news on one page). As a result, TypoScript will be loaded into one large array, which the TYPO3 engine will look into during rendering.

How does a TYPO3 site start?

Oddly enough, it all starts with a regular HTML page that will be used as a template. Usually, so-called markers are inserted into the page (an example is visible in the picture). After we have prepared the HTML template, we should start a test page in the backend. Then we can proceed to the TypoScript template. In its simplest working form, TypoScript will simply populate the template with whatever is written in the backend. An alternative to markers is the TemplaVoila extension, which allows you to link output locations to the tags used in the HTML template by id. TemplaVoila also gives the editor more flexible column settings, but the first option is better versioned with CVS, since all template information is written to files and not to the database.

His majesty backend

It will take several articles to describe all the functionality of the backend, here I will only briefly mention the basics. The backend can be divided into three parts: menu, pagetree and work-area (from left to right).

Menu

On the left is a menu, with which we select the various functions of TYPO3 (K.O.). Often, to change a particular setting, you need to select a function from the menu and additionally select a page in the pagetree.

The site structure in TYPO3 is always visible as a tree. In the picture, four sites are combined in one TYPO3 installation. They have different designs, different content, and are available under different domains. This can be convenient if the customer needs a separate page for a new project, but does not want to retrain to a new CMS, and the server can be left as is.

work area

On the right we see the work-area. This is where the input of all data, texts, pictures and other things takes place. Unlike the menu and pagetree, which practically do not change, the work-area changes in accordance with the combination of the selected menu item and page.

Last but not least

At the end of this article, I would like to say that TYPO3 writes pages to the cache (without the TYPO3 cache this is a perversion), has an easily customizable search engine (for large sites there is an extension for solr), can export to PDF, supports RSS, can authorize users via LDAP, can draw pictures with imagemagick/gd and many other interesting things. TYPO3 has long been an international project with a large community.
I would be glad if I managed to interest someone in
