Codeigniter 2.0.2, TinyMCE or CKEditor – style attribute lost after update
If you’re using WYSIWYG TinyMCE or CKEditor and framework CodeIgniter version >2.0, you can have problem with dissapearing style attribute.
You set style like <span style=”color:blue;”></span> and after submitting the form you get <span></span>.
Where the hell is style=”” ?
Probably you have this option enable in config.php file :
$config['global_xss_filtering'] = TRUE;
After disabling global filtering , WYSIWYG do not lose styles.
Personally, I did not want to disable this feature so I made a workaround ;o)
Edited based on Bart’s suggestion to not mess with core files ;o)
This security was added for some reason, so to not get rid it completly I created array that store the addresses to which the tag style is not to be removed.
You need to create MY_Security.php file as extension for core Security class and add modified function _remove_evil_attributes.
And that’s it.
