How do I stop parsing of BB code?

Right now on my current version I hacked it so function handle_bbcode_img($bbcode, $dobbimagecode) does not work unless you are a certain user group, to stop trolls.

Now with 3.5 this is gone. I can't update until I find where this code is now.

What file is the parsing of the IMG tag in now???????

You should be able to use a plugin to achieve what you want.

How would I use a plugin to do that? I'm not very technical.

I looked throughout class_bbcode and I can't see a clear cut function that does it. Can someone point me to which function in that file handles the parsing of the IMG tag or explain how to setup a plugin to do what I need.

File class_bbcode.php, around line 1714:

PHP Code:


		
			
    /**

    * Handles an [img] tag.

    *

    * @param    string    The text to search for an image in.

    * @param    string    Whether to parse matching images into pictures or just links.

    *

    * @return    string    HTML representation of the tag.

    */

    function handle_bbcode_img($bbcode, $do_imgcode, $has_img_code = false)

Great! Thanks very much.

Wait. Thats not the best method. (modifying code when you dont have to is baaad :))

plugin bbcode_parse_start,

PHP Code:


		
			
if(is_member_of($this->registry->userinfo, X)) { 
$dobbimagecode = true; 
}
else
{
$dobbimagecode = false;
}

I didn't say that it's a best method. I just pointed at a location. As for your method, which is definitely better, the most error-proof solution would be simply:

PHP Code:


		
			
if(!(is_member_of($this->registry->userinfo, X) OR is_member_of($this->registry->userinfo, Y)))

{

    $dobbimagecode = false;

}

Whereas the "true" assignment in your code might cause unexpected behavior in some cases when imgcode should not be parsed.

The easiest to use modify code would be:

PHP Code:


		
			
$usergroupids_no_img = 'X,Y,Z';

$usergroupids_no_img = explode(',', $usergroupids_no_img);



foreach ($usergroupids_no_img as $usergroupid)

{

    if(!is_member_of($this->registry->userinfo, $usergroupid))

    {

        $dobbimagecode = false;

        break;

    }

}

The reason there is a break statement is to stop checking for usergroups once a restricted one has been found - in other words, for optimization.

;)

It is unnecessary to use multiple is_member_of calls. You can pass an array of usergroupids.

Really? I didn't know. Thanks for pointing that out :) It's not really an "array", though. Rather an expanded list of parameters.

Code:

if(!is_member_of($this->registry->userinfo, X, Y, Z)) 

{ 

    $dobbimagecode = false; 

}
