In "List of fields to display in admin Page List" (template settings) how to display field from 1st repeater field item?


Recommended Posts

For a repeater field called datetimes, when I just put "{datetimes.date} {datetimes.time}" the output for one with multiple entries is (paraphrased):

1stdate, 2nddate 1sttime, 2ndtime

Is there a way of just specifying the 1st item's values in the repeater here?

It's possible with a hook.

In the "List of fields to display in the admin Page List" setting for the template, enter a string that identifies where the value from the first repeater will go, e.g. first_repeater_datetime. Don't put the normal { } delimiters around this string.

Then add a hook like this in /site/ready.php:

$wire->addHookAfter('ProcessPageListRender::getPageLabel', function(HookEvent $event) {
	$page = $event->arguments(0);
	$out = $event->return;
	if($page->template == 'your_template') {
		$datetime = '';
		if($page->datetimes->count) {
			$first_item = $page->datetimes->first();
			$datetime = $first_item->date . ' ' . $first_item->time;
		$event->return = str_replace('first_repeater_datetime', $datetime, $out);
