Appendix A – PHP include scripts¶
Including your script¶
This section should give you some pointers on what you can process in your script and which functions and variables you can access.
Your script is included inside the class
\TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer
in the
EXT:frontend/Classes/ContentObject/ContentObjectRenderer.php (GitHub)
script. Thereby your file is a part of this object
(ContentObjectRenderer
). This is why you must return all
content in the variable $content
and any TypoScript configuration is
available from the array $conf
(it may not be set at all though, so
check it with is_array()
)
$content¶
Contains the content, which was passed to the object, if any. All content, which you want to return, must be in this variable.
Do not output anything directly in your script.
$conf¶
The array $conf
contains the configuration for the USER cObject.
Try debug($conf)
to see the content printed out for debugging!
White spaces¶
Because nothing is sent off to the browser before everything is
rendered and returned to \TYPO3\CMS\Frontend\Http\RequestHandler
(which originally set off the rendering process), you must ensure
that there's no whitespace before your <?php
tag
in your include or library scripts! You should not use the closing PHP tag
?>
.
$GLOBALS['TSFE']->set_no_cache()¶
Call the function $GLOBALS['TSFE']->set_no_cache()
, if you want to
disable caching of the page. Call this during development only! And
call it, if the content you create may not be cached.
Note
If you make a syntax error in your script that keeps PHP
from executing it, then the $GLOBALS['TSFE']->set_no_cache()
function is not executed and the page is cached! So in these
situations, correct the error, clear the page-cache and try again.
This is true only for USER
and not for USER_INT
, which is
rendered after the cached page!
Example:¶
$GLOBALS['TSFE']->set_no_cache();
ContentObjectRenderer::cObjGetSingle(value, properties[, TSkey = '__'])
¶
A method of TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer
.
Gets a content object from the $conf
array.
Example:¶
$content = $cObjectRenderer->cObjGetSingle($conf['image'], $conf['image.'], 'My Image 2');
This would return any IMAGE cObject at the property image
of the
$conf
array for the include script!
ContentObjectRenderer::stdWrap(value, properties)
¶
A method of TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer
.
Hands the content in "value" to the stdWrap function, which will process it according to the configuration of the array "properties".
Example:¶
$content = $cObjectRenderer->stdWrap($content, $conf['stdWrap.']);
This will stdWrap the content with the properties of .stdWrap
of the
$conf
array!
Internal variables in the main frontend object, TSFE¶
There are some variables in the global object, TSFE (TypoScript
Frontend), you might need to know about. These ARE ALL READ-ONLY!
(Read: Do not change them!) See the class
\TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController
for the
full descriptions.
You can retrieve the TypoScriptFrontendController
via the
request attribute
frontend.controller.
For instance, if you want to access the variable id
, you can do so by
writing: TypoScriptFrontendController->id
.

The page record
TypoScriptFrontendController->feuser¶
