I tested some code changes that would allow for this. It will work, but you will introduce a huge problem that this product was designed to defeat. Wild looking posts. Here is an example:

--------START

THIS:

[QUOTE ]Test[QUOTE ]Nest #1[QUOTE ]Nest #2[QUOTE ]Nest #3[/QUOTE ]
[QUOTE ]in No Parse[/QUOTE ]
[code ][QUOTE]in Code [/code ]
[php ][QUOTE]in PHP[/php ]
[/QUOTE ][/QUOTE ][/QUOTE ]

RENDERS AS THIS:

[QUOTE]Test[QUOTE]Nest #1

Quote:

Nest #2

Quote:

Nest #3

[QUOTE]in No Parse[/QUOTE]

Code:

PHP Code:


		
			
[QUOTE]in PHP<div style="margin:20px; margin-top:5px; ">

    <div class="smallfont" style="margin-bottom:2px">Quote:</div>

    <table cellpadding="6" cellspacing="0" border="0" width="100%">

    <tr>

        <td class="alt2">

            <hr />

            

                

            

            <hr />

        </td>

    </tr>

    </table>

</div>

Quote:

[/QUOTE]

--------END

What is going wrong here? This product would tell you that the issue was mismatched quote tags. If you set it up to NOT detect this within PHP and CODE tags, then you might as well not use it at all.

Installed, tested, works like a charm. Great Mod, thanks!

It looked the same, except for a comment. I replaced the code and saved the file anyway in case I missed something.

On testing, it still doesn't work.

Oops! I just gave you the Parse function, here is the entire code (with remarks):

PHP Code:


		
			
/**

* Quotes Validation Class

*

* @product    vqbc_rayj2009

*

*/

class vqbc_VerifyQuotes {



  /**

  * Parses the post message.

  *

  * @param  string  text to be validated for matching quote tags

  */

  public function Parse($text) { //returns TRUE if bad quote found



    $text = preg_replace('#\[quote.*?\]#i','[quote]',$text);

    $text = preg_replace('#\[quote\]\[\/quote\]#i','',$text);

    $text = preg_replace('#\[noparse\].*?\[\/noparse\]#si','',$text);



    $text = $this->do_parse($text);

    return preg_match('/\[quote.*?\]|\[\/quote\]/si',$text);

  }



  /**

  * sub-parsing function

  *

  * @param  string  (internal call only)

  */

  private function do_parse($text) {

    if(is_array($text)) { $text = $text[1]; }

    $regex = '#\[quote\]((?:[^[]|\[(?!/?quote\])|(?R))+)\[/quote\]#i';

    return preg_replace_callback($regex,array($this,'do_parse'),$text);

  }

}

still doesn't work.

I'll reinstall from scratch tomorrow and see if it clears up.

Ok.

Also, what exactly does the system tell you when you have a quote with more than 8281 characters?

I have had to disable this plugin for 4.x.x as it has been causing problems for those trying to post long posts in quote tags. My host narrowed it down to this plugin and sure enough, as soon as it was disabled all the posting issues went away.

A shame, as it is a useful plugin. Just doesn't seem to work.

I am waiting on my host to respond to my request for additional info. In the meantime, you can take a look at this thread I started on vbulletin.com. The issue that I started the thread about was being caused by this plugin.

http://www.vbulletin.com/forum/forum...ong-post-error

This is what the host said in an email to me when this plugin was finally identified as the issue:

Quote:

Hey Joe, the class_verifyquotes.php plugin appears to be the culprit.
Are you able to disable that and confirm if it fixes it? I tried to
just rename the file but it's still getting called and giving a blank
page. While slightly better than a crash, i think disabling it or
updating that plugin ought to fix the problem.

Hope that helps.
