Loading MooTools and jQuery from CDN is no longer supported, because it does not provide any advantage anymore.
More information: #2438
The CSS classes "first" and "last" are no longer applied to articles and content elements. Use CSS selectors instead.
More information: #239
The contao/image
library got updated from version 0.3 to 1.0. See
contao/image/UPGRADE.md to get more information about the changes.
The body class for the user agent (via the {{ua::class}}
insert tag) has been
removed in Contao 4.8
to improve caching capabilities. Adjust your CSS or use
JavaScript if you need information about the user agent on the client side.
The MediaElement.js component along with its js_mediaelement
template has
been removed in Contao 4.8 due to widespread support of HTML5 videos in current
browsers. Use the HTML5 video element natively or integrate your own video player
solution manually.
The "Anonymize Google Analytics" flag in the back end settings has been
removed. IP addresses are anonymized by default in the analytics_google.html5
template now.
The "Anonymize IP addresses" flag in the back end settings has been removed. It
was used to bypass IP anonymization in the System::anonymizeIp()
method,
which is no longer supported.
The $GLOBALS['TL_CONFIG']['maxImageWidth']
parameter has been deprecated. Use
responsive images instead.
The "flash movie" front end module has been removed.
The pagination.html5
and be_pagination.html5
templates now use a <nav>
element as container and a <strong>
element to mark the active item:
<!-- OLD -->
<div class="pagination block">
...
<li><span class="active">...</span></li>
...
</div>
<!-- NEW -->
<nav class="pagination block" aria-label="...">
...
<li><strong class="active">...</strong></li>
...
</nav>
The $_SESSION['TL_LANGUAGE']
flag has been removed.
The image service no longer supports upscaling images for reasons of bandwidth and storage consumption. Images should be upscaled via CSS if needed.
The form template form.html5
has been renamed to form_wrapper.html5
, so it
can be overridden with a custom template in the form settings.
Since the String
class is not compatible with PHP 7, we have renamed it to
StringUtil
. The String
class remains available for reasons of backwards
compatibility, however it has been deprecated and will be removed in a future
version.
The mime icons have been removed from all front end templates. Instead, a new
style sheet called icons.css
has been added to the layout builder, which
restores the mime icons for downloads and enclosures via CSS.
The "article_raster_designer" hook has been removed. Use the "getArticles" hook instead and return a string to override the default articles content.
The "add submit button" option in the form generator has been removed. To
generate an inline form, add a text field and a submit button and assign the
CSS class inline-form
to the form element (requires the form.css
style
sheet to be enabled in the page layout).
The field "space before/after" has been removed. Use a CSS class instead and define the spacing in your style sheet.
If an element is included in another element, the CSS classes are now merged
instead of overwritten, e.g. if content element A has the CSS class elemA
and
includes a front end module with the CSS class elemB
, both CSS classes will
be applied (class="elemA elemB"
).
Here's how to select the elements separately:
.elemA {
/* Content element only */
}
.elemB {
/* Content element and front end module */
}
.elemB:not(.elemA) {
/* Front end module only */
}
The form option "tableless" has been removed, because all forms are now
tableless by default. Instead, the form.css
style sheet of the layout builder
has been enhanced to provide basic formattings for labels and input fields.
By default, labels and input fields are listed underneath each other. However,
if you add the CSS class horizontal-form
to a form, they will be aligned in a
horizontal layout, similar to the old table-based layout.
If you add the CSS class inline-form
, the widgets will be aligned vertically.
The form field "headline" has been removed in favor of the "explanation" field.
Every form now appends its numeric ID to the FORM_SUBMIT
parameter, so custom
forms used for triggering modules such as the login module have to be adjusted
to pass the correct form ID (e.g. tl_login_12
instead of tl_login
).
If a front end form is set up to store the submitted data in the database, date and time fields are now automatically converted to Unix timestamps.
The meta keywords tag has been removed from the fe_page.html5
template, as
it does not serve a purpose anymore. If you still want to use it, adjust the
template as follows:
<?php $this->extend('fe_page'); ?>
<?php $this->block('meta'); ?>
<?php $this->parent(); ?>
<meta name="keywords" content="<?= $this->keywords ?>">
<?php $this->endblock(); ?>
The following templates have been renamed to match the content element or module key:
ce_accordion
->ce_accordionSingle
ce_accordion_start
->ce_accordionStart
ce_accordion_stop
->ce_accordionStop
ce_slider_start
->ce_sliderStart
ce_slider_stop
->ce_sliderStop
mod_article_list
->mod_articlelist
mod_article_nav
->mod_articlenav
mod_random_image
->mod_randomImage
mod_change_password
->mod_changePassword
mod_event
->mod_eventreader
mod_newsletter_list
->mod_newsletterlist
mod_newsletter_reader
->mod_newsletterreader
The following templates have been consolidated:
ce_hyperlink_image
->ce_hyperlink
mod_article_plain
->mod_article
mod_article_teaser
->mod_article
mod_login_1cl
->mod_login
mod_login_2cl
->mod_login
mod_logout_1cl
->mod_login
mod_logout_2cl
->mod_login
mod_search_advanced
->mod_search
mod_search_simple
->mod_search
mod_eventmenu_year
->mod_eventmenu
mod_newsmenu_day
->mod_newsmenu
mod_newsmenu_year
->mod_newsmenu
nl_list
->mod_newsletterlist
nl_reader
->mod_newsletterreader
Generally, we now require the template names to match the content element or
module keys, so if your module has the key taskList
, the corresponding
template should be named mod_taskList.html5
.
Users can then create custom templates à la mod_taskList_custom.html
, which
will be shown in the "custom module template" list.
The keys of the following front end modules have been changed:
articleList
->articlelist
rss_reader
->rssReader
nl_list
->newsletterlist
nl_reader
->newsletterreader
The database classes have been mapped to the Doctrine DBAL, therefore custom drivers are no longer supported. If you have been using a custom driver for a database other than MySQL, use the corresponding Doctrine driver instead.
The dump()
function has been replaced by the Symfony debug bundle. Its output
will be added to the web profiler.
The style sheet files/tinymce.css
and the folder files/tiny_templates
have
been removed. If you want to use the feature, please adjust the TinyMCE config
file, which is now a template (e.g. be_tinyMCE.html5
).
The Frontend::parseMetaFile()
method was deprecated since Contao 3 and has
been removed in Contao 4.0.
The $_SESSION['TL_USER_LOGGED_IN']
flag has been removed.
Contao 4 only uses a single PHP entry point, namely the index.php
file. The
previous PHP entry points have been removed and a route has been set up for
each one instead.
contao/confirm.php
->contao_backend_confirm
contao/file.php
->contao_backend_file
contao/help.php
->contao_backend_help
contao/index.php
->contao_backend_login
contao/main.php
->contao_backend
contao/page.php
->contao_backend_page
contao/password.php
->contao_backend_password
contao/popup.php
->contao_backend_popup
contao/preview.php
->contao_backend_preview
contao/switch.php
->contao_backend_switch
The old paths are replaced automatically in the back end, still you should
adjust your templates to use $this->route()
instead:
// Old
<form action="contao/main.php">
// New
<form action="<?= $this->route('contao_backend') ?>">
The cron.php
entry point has been removed. Use the /_contao/cron
route
instead if you want to trigger the cron job manually.
In Contao 3 it was possible to disable aliases and make Contao use numeric IDs only. This was a workaround for an old IIS server, which has now been dropped.
More information: contao/core-bundle#118
The system/runonce.php
file is no longer supported. If you need to set up a
runonce.php
file, put it in the src/Resources/contao/config/
directory.
The DcaExtractor
class is no longer instantiable via new DcaExtractor()
.
Use the DcaExtractor::getInstance($table)
method instead.
The MooTools "slimbox" plugin has been removed. Use the MooTools "mediabox" or the jQuery "colorbox" plugin instead.
The Message
class now supports scopes, which can optionally be passed as
second argument:
// Add an error message to "my-scope"
Message::addError('An error ocurred', 'my-scope');
// Generate all messages in "my-scope"
Message::generate('my-scope');
The scope defaults to TL_MODE
. The previous arguments of the generate()
method have been removed. If you want to output the messages without the
wrapping element, use Message::generateUnwrapped()
instead.
The "prepareFormData" hook now passes $this
as last argument, just like in
any other hook.
-
The navigation menus are now using
<strong>
instead of<span>
to highlight the active menu item. -
The search module is now using
<mark>
instead of<span>
to highlight the keywords. -
The newsletter channel menu is now using
<fieldset>
and<legend>
instead of<label>
and<div>
. -
The main section of the
fe_page.html
template now uses the<main>
tag. -
Submit buttons now use
<button type="submit">
instead of<input>
.
-
The book navigation module now uses the CSS class
previous
instead ofprev
for the link to the previous page. -
The pagination menu now uses the CSS class
active
instead ofcurrent
for the active menu item. -
The classes
odd
andeven
are now correctly assigned to tables. -
The form submit widget now uses the CSS class
widget widget-submit
instead ofsubmit_container
. -
The content syndication links of the
mod_article.html5
template now have CSS classes and the class "pdf_link" has been replaced with "syndication":
<div class="syndication">
<a href="..." class="print"></a>
<a href="..." class="pdf"></a>
<a href="..." class="facebook"></a>
<a href="..." class="twitter"></a>
</div>
In Contao 3 new File('tmp.txt')
automatically created the file if it did not
exist and all write operations such as $file->write()
or $file->append()
were carried out directly on the target file.
This behavior could already be changed in Contao 3 by passing true
as second
argument; the file was then only created if there was a write operation at all
and any operation was carried out on a temporary file first, which was then
moved to its final destination.
In Contao 4 this changed behavior has become the default and the second argument has been dropped.
In Contao 3 the user files in the files/
directory were publicly available
via HTTP by default, and it was possible to protect certain subfolders. Now,
due to a technical change, the user files are protected by default and
subfolders have to be published explicitly to be available via HTTP.
In Contao 3 the alias of an article was automatically used as its CSS ID, if
no custom CSS ID was defined. In Contao 4 the default CSS ID will be generated
from its numeric ID, e.g. article-1
.
In Contao 3 the table inspection methods of the Database
class processed both
tables and views. However, the Doctrine schema manager, which is used in Contao
4, only processes tables.
