I still don't understand. ^^' Yeah, it's not going to match but to replace {option1} {option2} and so on with something and I'm looking for to get to know what is this something. I'm almost sure it is %2$s with appended number, what I'm not sure is how the numbers are appended. For example would it be %3$s, %4$s etc? Probably no, %21$s %23$s ? or maybe %2+1$s, %2+2$s? I'm not a coder so it's difficult for me to interpret this. The question is what will be {option1} {option2} {option3} and so on transformed to after the replacement.

Hire is the whole code:

PHP Code:

!$this->is_wysiwyg())
{
    foreach ($this->tag_list['option'] AS $tag => $bbcode)
    {
        if (strpos($bbcode['html'], '{option1}') !== false)
        {
            unset($this->tag_list['option']["$tag"]['html']);
            $this->tag_list['option']["$tag"]['replace'] = preg_replace('/\{option(\d+)\}/e', "'%' . (intval('\\1')+1) . '\$s'", $bbcode['html']);
            $this->tag_list['option']["$tag"]['callback'] = 'handle_external';
            $this->tag_list['option']["$tag"]['external_callback'] = 'handle_bbcode_multioption';
        }
    }
}
