What a great idea!

Ok, so I tried this by putting this code in functions.php

	// enqueue our JS when ACF envques scripts
	add_action('acf/input/admin_enqueue_scripts', 'unique_repeater_checkbox_enqueue_script');
	
	function unique_repeater_checkbox_enqueue_script() {
		// enqueue acf extenstion
		
		// only enqueue the script on the post page where it needs to run
		/* *** THIS IS IMPORTANT
					 ACF uses the same scripts as well as the same field identification
					 markup (the data-key attribute) if the ACF field group editor
					 because of this, if you load and run your custom javascript on
					 the field group editor page it can have unintended side effects
					 on this page. It is important to alway make sure you're only
					 loading scripts where you need them.
		*/
			
		// your should change this to check for whatever
		// admin page(s) you want the script to load on
		global $post;
		if (!$post ||
				!isset($post->ID) || 
				get_post_type($post->ID) != 'page') {
			return;
		}
			
		$handle = 'acf-unique-repeater-checkbox';
		
		// I'm using this method to set the src because
		// I don't know where this file will be located
		// you should alter this to use the correct fundtions
		// to set the src value to point to the javascript file
		$version = acf_get_setting('version');
		if (version_compare($acf_version, '5.7.0', '<')) {
			$src = get_template_directory_uri() . '/library/js/unique-repeater-checkbox.js';
		} else {
			$src = get_template_directory_uri() . '/library/js/unique-repeater-checkbox-acf57.js';
		}
		// make this script dependent on acf-input
		$depends = array('acf-input');
		
		wp_enqueue_script($handle, $src, $depends);
		
	} // end function unique_repeater_checkbox_enqueue_script

Where I changed the post type to page since that’s where I load the repeater. And I changed the source so that it will load the JS while editing the specific page.

It seems to load the “unique-repeater-checkbox.js” NOT the “unique-repeater-checkbox-acf57.js”.

The JS file looks like this where I edited the data-key to match the true/false field.

	jQuery(document).ready(function($){
		if (typeof acf == 'undefined') { return; }
		
		var unique_repeater_checkbox = acf.ajax.extend({
			/*
					why am I extenting the acf.ajax method/property
					since I'm not using ajax in this example?
					
					It's easier. Since most of the time when I'm going to be
					adding functionality to ACF I'm more than likely going to
					be adding several actions and one of them is more than likely
					going to include some kind of ajax. I'm more than likely going
					to build it all into a single extension for the site and I would
					put all of my events and functions in a that single extension and
					call it something like {$client's name}_acf_extension
			*/
			
			events: {
				// for each field that you want to apply this to add a 'change' event line
				// and copy the field key for the field and paste it in the "data-key" value
				'change [data-key="field_5d945ca8ae892"] input': '_update_unique_checkbox',
			},
			
			_update_unique_checkbox: function(e) {
				var $checked = e.$el.prop('checked');
				if (!$checked) {
					// prevent the field from being unchecked and return
					e.$el.prop('checked', true);
					return;
				}
				// the field is checked, get the currently selected item
				var $id = e.$el.prop('id');
				// get the data-key
				var $key = e.$el.closest('.acf-field').attr('data-key');
				
				// get the field from all of the rows in the repeater
				// exclude hidden fields and the ACF clone row
				var $list = $('[data-key="'+$key+'"] input').not('[data-key="'+$key+'"] input[type="hidden"]').not('.acf-clone [data-key="'+$key+'"] input');
				if ($list.length == 1) {
					// if there is only one row then bail
					// nothing needs to be done
					return;
				}
				// uncheck all of the other rows except the currently checked one
				for (i=0; i<$list.length; i++) {
					var $item_id = $list[i].getAttribute('id');
					if ($id != $item_id) {
						// if not the current item then set to false
						$list[i].checked = false;
					}
				}
			},
			
		});
		
	});

But it still doesn’t work. When I have one checkbox checked and check another one it doesn’t uncheck the first one. Regardless of if I “Update” the page or not. Worth mentioning is that I also do not have the Styled UI on for that field. It doesn’t say anything in the console.

What might be wrong?
