How to find and change TYPO3 settings.

This is a small reference to give an idea on how to find a TYPO3 setting that can be changed, and how to change it.

Easy:

  1. go to BE
  2. Click the Configuration module in left menu bar
  3. Now use the drop down at the top, and select TYPO3_CONF_VARS.
  4. Search for what you need
  5. Click on the needed title
  6. Now you get a array like this:
    $TYPO3_CONF_VARS[‘EXTCONF’][‘cachecleaner’][‘tables’][‘cache_pages’][‘expireField’] = ‘expires’;
  7. Change this in your extension (in a PHP file) and include this file in ext_localconf.php
    OR Directly write inside ext_localconf.php (well this may not be very clean)

NOTE: The CONFIGURATION Module is like a TREE browser which lists all kind of available configurations available in TYPO3.
So we have endless chance to change and customize almost anything here!

NOTE2: The TYPO3 Configuration Module is also a place where you can see the current configuration that is in use.
This can be used for wide range of debugging, such as:

  1. To analyze if a HOOK/XCLASS has been declared or not
  2. To see if the configuration we specified has been really recognized by TYPO3

ENJOY!
