Exclude pages from Insert link > Select Page

[Didjee]

I want to exclude pages with certain templates from Insert link > Select Page. Is this possible using a hook?

You probably want to exclude by template for the "Link to URL" autocomplete field too.

// ProcessPageEditLink > Link to URL: exclude pages by template
$wire->addHookBefore('InputfieldPageAutocomplete(name=link_page_url)::render', function(HookEvent $event) {
	$inputfield = $event->object;
	$exclude_templates = ['basic_page', 'movies'];
	$inputfield->findPagesSelector .= ', template!=' . implode('|', $exclude_templates);
});

// ProcessPageEditLink > Select Page / Select Child Page: exclude pages by template
$wire->addHookAfter('ProcessPageEditLink::execute', function(HookEvent $event) {
	$exclude_templates = ['basic_page', 'movies'];
	$css = '';
	foreach($exclude_templates as $template_name) {
		// Hide the page list item (and its children)
		$css .= ".PageListTemplate_$template_name, ";
		// Or just hide the "Choose page" button, if the child pages should remain selectable
		// $css .= ".PageListTemplate_$template_name .PageListActionSelect, ";
	}
	$css = rtrim($css, ', ');
	$css .= ' { display:none !important; }';
	$event->return .= "<style>$css</style>";
});
