Help w/ bbcode

[ifm1989]

Another question. I am trying to make a bbcode that shows a user + a link to his account.

 

So, [user=1] would create a link to user 1's account

 

This is what I've added to the bbcode function:

 

$text = preg_replace('#\[user=(.*?)\]#si', '<a href="'.BASEDIR.'user?id=\1">'.getusername('\1').'</a>', $text);

 

And this is my getusername() function:

 

function getusername($user_id)

{

$user_id = stripinput((int)$user_id);

if($user_id == 0){

return 'INVALID USER ID';

}else{

$gsql = dbquery("SELECT user_name FROM ".DB_PREFIX."users WHERE user_id = '$user_id' LIMIT 1");

if(dbrows($gsql)){

$gdata = dbarray($gsql);

return $gdata['user_name'];

}else{

return 'ACCOUNT NOT FOUND';

}

}

return false;

}

 

I've highlighted in blue what i think is causing the problem. Right now, it is correctly making a link to the user account, but it's giving INVALID USER ID for the user name.

illegal, as the replacement string in preg_replace is to be static (same thing, nothing dynamic)

 

u will want to go with preg_replace_callback, so u can stick in the extra function getusername into the replacement string

This:

$text = preg_replace_callback('#\[user=(.*?)\]#si', '<a href="'.BASEDIR.'user?id=\1">'.getUserName('\1').'</a>', $text);

 

Returns this error:

 

Warning: preg_replace_callback() requires argument 2, 'INVALID USER ID', to be a valid callback in /home/galava/public_html/core.php on line 474

Bump for justice.

function prc($mathes)
{
   return '<a href="'.BASEDIR."user?id=$matches[1]">'. getUserName($matches[1]) . '</A>';
}
$text = preg_replace_callback('#\[user=(.*?)\]#si', 'prc', $text);
