Format date field in the 'Repeater item label'

[a-ok]

Is it possible to format a date in when using a date field as the 'Repeater item label'?

Quote

Enter the field name to use for repeater labels in the page editor, or leave blank to auto-generate. To use multiple fields, or to specify your own format string, surround field names in {brackets}. To include a repeater index number with each label, add "#n" somewhere in your format string.

{events_detail_dates_start_date} obviously returns the timestamp but we can't input PHP here in so I'm guessing not... but any thoughts?

You can hook into InputfieldRepeater::renderRepeaterLabel and change $event->return. 

wire()->addHookAfter('InputfieldRepeater::renderRepeaterLabel', function (HookEvent $e) {
    $field = $e->object->hasField;
    // check the field
    if ($field != "myRepeaterField") return;

    /** @var Page $page */
    $count = $e->arguments('cnt');
    $page = $e->arguments('page');


    $labelDate = date('y-m-d', $page->published);
    $label = substr($page->getText('title|body'), 0, 20);
    $e->return = "{$label} -- {$labelDate}";
});

Which renders as 

From the core:

// InputfieldRepeater.module

/**
* Render the repeater label
*
* @param string $label Default label
* @param int $cnt Item index (1-based)
* @param Page $page Repeater item
* @return string
*
*/
public function ___renderRepeaterLabel($label, $cnt, Page $page) { ... }

Thanks for the help. I did try this but it's returned as 1 January 1970. 'events_detail_dates' is the repeater and 'events_detail_dates_start_date' is the date field.

$wire->addHookAfter('InputfieldRepeater::renderRepeaterLabel', function($event) {

    if ($event->object->hasField == 'events_detail_dates') {
        $event->return = date('D. j F Y', $event->events_detail_dates_start_date);
    }

});

You need to use $page argument. Also remember to check if field is actually the field you want.

wire()->addHookAfter('InputfieldRepeater::renderRepeaterLabel', function (HookEvent $e) {
    /** @var Page $page */
    $field = $e->object->hasField;

    // check the field
    if ($field != "events_detail_dates") return;

    $page = $e->arguments('page');
    $e->return = date('D. j F Y', $page->events_detail_dates_start_date);
});

Thanks, abdus!
