le="color: #000000"><?php Notice: Undefined index: extensions in file /class/module.textsanitizer.php line 622 Warning: array_filter() expects parameter 1 to be array, null given in file /class/module.textsanitizer.php line 622
This was a tricky bug, at least for me!
First, I was looking at the chain of events, trying to figure out what was calling the function executeExtensions, inside which the array_filter was located?
It was:
displayTarea
--> xoopsCodeDecode($text);
------> executeExtensions
I was looking at the parameters of the various displayTarea calls from within WF-Links, like this one:
le="color: #000000"><?php $link['description2'] = $wfmyts -> displayTarea( $link_arr['description'], 1, 1, 1, 1, 1 );
but couldn't find anything wrong.
But in the debugger, I saw that the value for $this->config['extensions'] was null:
le="color: #000000"><?php $this->config['extensions'] = null
I compared a similar call to displayTarea in xForms,
le="color: #000000"><?php $xoopsTpl->assign('forms_intro', $myts->displayTarea($xoopsModuleConfig['intro']));
and it was:
le="color: #000000"><?php $this->config['extensions'] = {array}[11] iframe = 0 image= 1 flash = 1 youtube = 1 mp3 = 0 wmp = 0 wiki = false mms = 0 rtsp = 0 ul = 0 li = 0
So something was wrong with our $wfmyts.
WF-Links, the same as XoopsTube, is extending MyTextSanitizer in /class/myts_extended.php
le="color: #000000"><?php class wflTextSanitizer extends MyTextSanitizer { function wflTextSanitizer() { } function htmlSpecialCharsStrip( $text ) { return $this -> htmlSpecialChars( $this -> stripSlashesGPC( $text) ); } }
Now the question, what is wrong with it, and what consequences does it have?
I realized that the function
le="color: #000000"><?php function wflTextSanitizer() { }
was overriding the original construction method of MyTextSanitizer:
le="color: #000000"><?php function __construct() { $this->path_basic = XOOPS_ROOT_PATH . '/class/textsanitizer'; $this->path_plugin = XOOPS_ROOT_PATH . '/Frameworks/textsanitizer'; $this->config = $this->loadConfig(); }
and as a result the "$this->loadConfig()", which was loading the extensions, was never executed.
After removing it, all the errors related to "Undefined index: extensions" are gone.
