Delete All Images In Gallery At Once

Is there anyway of either being able to press a button that deletes all of the images in the gallery or being able to select all of the images and then deleting them?

There currently isn’t anyway to do this in ACF. You could try submitting a feature request here https://support.advancedcustomfields.com/new-ticket.

You might also use the acf/render_field https://www.advancedcustomfields.com/resources/acf-render_field/ hook to add additional controls to the gallery field and then figure out how to add custom javascript to the field to make it work https://www.advancedcustomfields.com/resources/adding-custom-javascript-fields/. Unfortunately, that’s all I can offer because I don’t know exactly how to do this.

Thanks. I managed to resolve this myself thanks to your advice.

For anyone who is interested, I just did the following:

function clear_button( $field ) {

	echo '<p><a href="#" class="acf-button button button-primary acf-gallery-clear">Clear Images</a></p>';

}
add_action( 'acf/render_field/type=gallery', 'clear_button', 10, 1 );

function my_acf_input_admin_footer() {
	
?>
<script type="text/javascript">
(function($) {
	
	$('.acf-gallery-clear').click(function() {
  $('.acf-gallery-remove').click();
});
        
})(jQuery);	
</script>
<?php
		
}

add_action('acf/input/admin_footer', 'my_acf_input_admin_footer');

This just clears the images from the gallery rather than deletes them off the website which I may do in the future but for now I just needed a way of starting again with the gallery.

I’ve rewritten a little bit to also delete the images from the media library

functions.php

function azrClearButton( $field ) {
		global $post;
		echo '<p style="text-align:right"><a href="#" class="acf-button button button-primary acf-gallery-clear" data-postid="'.$post->ID.'">Delete all Images</a></p>';
	}
	add_action('acf/render_field/type=gallery', 'azrClearButton', 10, 1 );
	
	function azrDeleteImagesFromGallery() {		

		?>
		<script type="text/javascript">
			(function($) {
				var azr_TemplateDir = "<?php bloginfo('template_directory') ?>"
				$('.acf-gallery-clear').click(function() {
					console.log('test');
					var postid = $(this).data('postid');
					$.ajax({ 
					    type: 'post', 
					    url: azr_TemplateDir+'/ajax/delete-gallery.ajax.php',
					    data: {'postid': postid}, 
					    dataType: 'json',
						success: function (data) { 
							location.reload();
						}
					});
				});
			
			})(jQuery);	
		</script>
		<?php
	}
	add_action('acf/input/admin_footer', 'azrDeleteImagesFromGallery');

AJAX FILE

require('../../../../wp-load.php');
global $post;
$postid = $_POST['postid'];
$args = array(
	'post_type' => 'attachment',
	'posts_per_page' => -1,
	'post_status' => 'any',
	'post_parent' => $postid
); 
$attachments = get_posts($args);
foreach($attachments as $attachment) :
	wp_delete_attachment($attachment->ID, true );
endforeach;
