[TYPO3-english] Re: Disable RealURL for specific URL

[Olivier Seubert]

I found the following solution: Setting a RealUrl hook to prevent RealURL from trying to parse the URL:

In your extension's ext_localconf.php you set e.g.:
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['realurl']['decodeSpURL_preProc'][] = 'EXT:yourextension/Classes/Hooks/RealUrlHook.php:\\YourVendor\\YourExtension\\Hooks\\RealUrlHook->decodeSpURL_preProc';

And in yourextension/Classes/Hooks/RealUrlHook.php:
<?php

namespace YourVendor\YourExtension\Hooks;

/**
 * Hook functions for RealURL.
 *
 * @package yourextension
 * @license http://www.gnu.org/licenses/gpl.html GNU General Public License, version 3 or later 
 */
class RealUrlHook {

  /**
    * Hook function to prevent RealURL from further parsing, 
    * when parameter is set via HTTP-request. Instead forward to
    * root page.
    *
    * @param array $params
    * @param tx_realurl $ref
    */  
  function decodeSpURL_preProc(&$params, &$ref) {
    // check if get parameter is set
    if (($_SERVER !== null) &&
        array_key_exists('QUERY_STRING', $_SERVER) &&
        preg_match('/(?:^|.*&)tx_yourextension\\[bypassrealurl\\]=(?:1|true).*/is', $_SERVER['QUERY_STRING'])) {
      // if yes, forward to root page
      $params['URL'] = "/";
    }
  }
}

Hope this helps somebody.
