Debugging¶
Before diving into the topic here are a few hints about debugging in TYPO3 CMS.
The TYPO3 Core provides a simple debug()
(defined in
EXT:core/Classes/Core/GlobalDebugFunctions.php
). It wraps around
\TYPO3\CMS\Core\Utility\DebugUtility::debug()
and will output debug
information only if it matches a set of IP addresses (defined in
$GLOBALS['TYPO3_CONF_VARS']['SYS']['devIPmask']
).
For example, the following code:
debug($_COOKIE, 'cookie');
will produce such an output:
In general, look at class \TYPO3\CMS\Core\Utility\DebugUtility
for useful
debugging tools.
