AddHook causes error 324

[verdeandrea]

Hi guys,

i've working on this site based on pw. I'm getting the error 324 err_empty_response in my homepage, but soon as i delete this line

wire()->addHook("Page::wordLimiter", null, "wordLimiter");

everything is working fine again. 

This is the complete code of the hook

function wordLimiter(HookEvent $event){
    $field = $event->arguments[0]; // first argument
    $limit = $event->arguments[1];
    $endstr = isset($event->arguments[2]) ? $event->arguments[2] : ' …';
    $page = $event->object; // the page
    $str = $page->get($field);
    $str = strip_tags($str);
    if(strlen($str) <= $limit) return;
    $out = substr($str, 0, $limit);
    $pos = strrpos($out, " ");
    if ($pos>0) {
        $out = substr($out, 0, $pos);
    }
    return $event->return = $out .= $endstr;
}
wire()->addHook("Page::wordLimiter", null, "wordLimiter");

and is written on the top of the page.

I really don't get what can cause that problem. Could you please help and suggest what can be wrong? Thanks

Hi verdeandrea,

What happens if you try this...

function wordLimiter(HookEvent $event){
    $field = $event->arguments[0]; // first argument
    $limit = $event->arguments[1];
    $endstr = isset($event->arguments[2]) ? $event->arguments[2] : ' …';
    $page = $event->object; // the page
    $str = $page->get($field);
    $str = strip_tags($str);
    if(strlen($str) <= $limit) return;
    $out = substr($str, 0, $limit);
    $pos = strrpos($out, " ");
    if ($pos>0) {
        $out = substr($out, 0, $pos);
    }
    $out .= $endstr;
    $event->return = $out;
}

...?

Thanks netcarver,

i've tried that but it's still not working.

Could it be something related to "addHook"?
