Hook: Check field data and prevent page from being saved

[Susticle]

Hello everybody,

I'm doing websites with Processwire for some time now. Now there is the first time I need to setup a hook.

I created a module, that was no problem. I added a hook:

Quote

$this->pages->addHookbefore('save', $this, 'checkMethod');

In checkMethod I can check for errors and give out an error message with $this->error. With event->replace in case of errors I can prevent saving the wrong data. Everything's fine.

But still I get the message that the page has been saved. So I think I did something wrong.

What's the correct way to add a hook that checks the data, gives out an error message and prevents the page from being saved?

Thanks,
Lars

Hook into Pages::saveReady instead and throw error inside checkMethod()
