Using hooks to populate a field, how do you stop an error message

[cb2004]

I am using hooks to populate some required field values. The populating is done, but I get an error message if it is a required field regardless if it has been populated. Which hook should I use to save the values, then the page displays without an error?

Cheers.

$pages->addHookAfter("save", function($event) {
	$page = $event->arguments(0);

	// apply job title if a quote is selected, apply customer address if customer selected
	if ($page->template->id == 48) {
		if ($page->page_quote && empty($page->title)) {
			$page->setAndSave("title", $page->page_quote->title);
		}

		if ($page->page_customer && empty($page->textarea_1)) {
			$page->setAndSave("textarea_1", $page->page_customer->textarea_1);
		}
	}
});

hi cb,

i think addhookafter "saveReady" should be fine.

and just set the values, the save will take place afterwards:

// change this
$page->setAndSave("title", $page->page_quote->title);

// to that
$page->title = $page->page_quote->title;

If it doesnt work you could also try this one (not tested):

$pages->addHookBefore('saveReady', function($event)

Ben provided the correct hook here:

So we end up with:

$pages->addHookBefore("ProcessPageEdit::processInput", function($event) {
	$page = $event->object->getPage();

	// apply job title if a quote is selected, apply customer address if customer selected
	if ($page->template->id == 48) {
		if ($page->page_quote && empty($page->title)) {
			$page->setAndSave("title", $page->page_quote->title);
		}

		if ($page->page_customer && empty($page->textarea_1)) {
			$page->setAndSave("textarea_1", $page->page_customer->textarea_1);
		}
	}
});
