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 "ContentObjectRenderer" in the typo3/sysext/frontend/Classes/ContentObject/ContentObjectRenderer.php 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!

Remember, don't output anything (but debug code) 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 and after your <?php...?> tags in your include or library scripts!

$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();

$this->cObjGetSingle(value, properties[, TSkey = '__'])

Gets a content object from the $conf array. $TSkey is an optional string label used for the internal debugging tracking.

Example:

$content = $this->cObjGetSingle($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!

$this->stdWrap(value, properties)

Hands the content in "value" to the stdWrap function, which will process it according to the configuration of the array "properties".

Example:

$content = $this->stdWrap($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: Don't change them!) See the class TypoScriptFrontendController for the full descriptions.

Important

In previous versions, the properties gr_list, loginUser and beUserLogin where used for context specific information. Since TYPO3 v9 these variables have been replaced by the TYPO3 Context API.

If you for instance want to access the variable "id", you can do so by writing: $GLOBALS['TSFE']->id
