Check for errors in hook

[renobird]

How do I check for errors (required fields not filled in, etc..)?

I need to redirect after a successful page save, but only if there are no errors.

public function init() {
    $this->pages->addHookAfter('save', $this, 'redirectMe');
}

public function redirectMe($event){
    if ($event->arguments(0) != "news") return;
    $this->session->redirect($this->config->url->admin . "/processwire/news/");
}

The code above redirects even if there are errors on the page.

I do think field errors are cleaned in the InputfieldWrapper render() methode.

So maybe you need an additional hook before InutfieldWrapper render and loop through the fields and count the errors.

Thanks Martijn,

That got me thinking, maybe I can just check the notices?

$errors = false;
foreach(wire('notices') as $notice) {
    $notice instanceof NoticeError ? $errors = true : "";

}

Haven't tried that yet, just riffing.

Will report back.

This seems to work. At least through some simple tests.

public function redirectMe($event){
    $page = $event->arguments(0);
    $errors = false;

    foreach(wire('notices') as $notice){
        if($notice instanceof NoticeError) $errors = true;
    }

    if (!$errors) $this->session->redirect($this->config->url->admin . "/processwire/news/");    
}

I'm not sure about that notices loop, if you didn't delete the install.php for example does that prevent your $session->redirect ?

Not sure, but in that case it's OK for it to fail, because the admin (me) has some cleanup to do.
