ACF Repeater Load More using AJAX

Have you ever wanted to show a limited amount of items when using an ACF repeater? Maybe you are using this to display images and to save on load time you only want to show a selective amount instead of loading them all. At the end of the day, having to load fewer images is going to speed up your site right?

In this example, we will show you the basics of adding load more functionality for an ACF repeater field. We are going to display a repeater called gallery and load only 9 items if there are more than 9 items we will display a ‘Load more’ button to programmatically load the rest.

So first of all our markup will look as follows:-

<div id="photo-gallery">
	<div class="row">
		if( have_rows('media') ): 
			$total = count(get_field('media'));
			$count = 0;
			$number = 8;					
			while ( have_rows('media') ) : the_row(); ?>						
					<div class="col-md-4 col-sm-6">
						<a class="mag-pop" data-img="<?php the_sub_field('image'); ?>" href="<?php the_sub_field('image'); ?>"><img class="img-gallery" alt="BeWILDerwood Gallery" src="<?php the_sub_field('image'); ?>" /></a>
				if ($count == $number) {
					// we've shown the number, break out of loop
				} ?>					
			<?php $count++; endwhile;
		else : endif;
	<a id="gallery-load-more" href="javascript: my_repeater_show_more();" <?php if ($total < $count) { ?> style="display: none;"<?php } ?>><h2 id="title-bg"><span>Load more</span></h2></a>

As you can see, $number defined the number of repeater items we want to initially display. We use the break; clause to prevent further images from loading.

Now moving on to the JavaScript:-

<script type="text/javascript">
	var my_repeater_field_post_id = <?php echo $post->ID; ?>;
	var my_repeater_field_offset = <?php echo $number + 1; ?>;
	var my_repeater_field_nonce = '<?php echo wp_create_nonce('my_repeater_field_nonce'); ?>';
	var my_repeater_ajax_url = '<?php echo admin_url('admin-ajax.php'); ?>';
	var my_repeater_more = true;
	function my_repeater_show_more() {
		// make ajax request
			my_repeater_ajax_url, {
				// this is the AJAX action we set up in PHP
				'action': 'my_repeater_show_more',
				'post_id': my_repeater_field_post_id,
				'offset': my_repeater_field_offset,
				'nonce': my_repeater_field_nonce
			function (json) {
				// add content to container
				// this ID must match the containter 
				// you want to append content to
				jQuery('#photo-gallery .row').append(json['content']);
				// update offset
				my_repeater_field_offset = json['offset'];
				// see if there is more, if not then hide the more link
				if (!json['more']) {
					// this ID must match the id of the show more link
					jQuery('#gallery-load-more').css('display', 'none');

We’ve added comments within the code so you can see what is happening through the process. Now we need to add the code to the functions.php file to load the additional items.

 * ACF Load More Repeater

// add action for logged in users
add_action('wp_ajax_my_repeater_show_more', 'my_repeater_show_more');
// add action for non logged in users
add_action('wp_ajax_nopriv_my_repeater_show_more', 'my_repeater_show_more');

function my_repeater_show_more() {
	// validate the nonce
	if (!isset($_POST['nonce']) || !wp_verify_nonce($_POST['nonce'], 'my_repeater_field_nonce')) {
	// make sure we have the other values
	if (!isset($_POST['post_id']) || !isset($_POST['offset'])) {
	$show = 9; // how many more to show
	$start = $_POST['offset'];
	$end = $start+$show;
	$post_id = $_POST['post_id'];
	// use an object buffer to capture the html output
	// alternately you could create a varaible like $html
	// and add the content to this string, but I find
	// object buffers make the code easier to work with
	if (have_rows('media', $post_id)) {
		$total = count(get_field('media', $post_id));
		$count = 0;
		while (have_rows('media', $post_id)) {
			if ($count < $start) {
				// we have not gotten to where
				// we need to start showing
				// increment count and continue
			<div class="col-md-4 col-sm-6">
				<a class="mag-pop" data-img="<?php the_sub_field('image'); ?>" href="<?php the_sub_field('image'); ?>"><img class="img-gallery" alt="BeWILDerwood Gallery" src="<?php the_sub_field('image'); ?>" /></a>
			if ($count == $end) {
				// we have shown the number, break out of loop
		} // end while have rows
	} // end if have rows
	$content = ob_get_clean();
	// check to see if we have shown the last item
	$more = false;
	if ($total > $count) {
		$more = true;
	// output our 3 values as a json encoded array
	echo json_encode(array('content' => $content, 'more' => $more, 'offset' => $end));
} // end function my_repeater_show_more

As you can see above, we are going to load an additional 9 images (or repeater values) on click of the load more button. Once all loaded items have appeared, we are hiding the load more button so that is no longer visible.

And that’s pretty much it! If this has helped you, feel free to drop a comment. If you need any help with this, feel free to get in touch and we’ll be happy to assist you! πŸ™‚

  1. I have followed your great tutorial … I have already created a gallery by ACF (ACF Repeater Load More using AJAX). But I face a problem. When I use $number = 8 on page template It will display 9 images … Again I am clearing this issue .. when I use $number = 0; This will be shown in Figure 1. Please fix the problem … asap … I’m waiting for your solution …

  2. Thanks for this solution, it works great. One question – is there any way to send AJAX request and get only repeater items with specific value of some field? Because I have some kind of checkbox filters for this repeater and I really don’t know how to get specific repeater items.

    1. Hi Taras,

      Not sure I fully understand, but you can change what is outputted here:

      <div class="col-md-4 col-sm-6">
      	<!-- This part -->

      to show any fields you want to display… If that is not the case, let me know the URL and I can check for you.

      1. No, it’s not a case. Unfortunately I can’t share the URL because website is on my local server only. I will try to explain again.
        So I have a repeater “Client Reviews”, and there is a radio-button subfield where administrator can choose source of each Review: “local review” or “trustpilot review”. Then I put value of this subfield like a class to repeater item on front end: or . So on front-end I get the list of repeater items (reviews) with one of classes – “local” or “”trustpilot”. Then I’ve implement your code to load this reviews by AJAX and it works perfect.
        BUT on front I also have a simple checkbox filter with “Local” and “Trustpilot” options. So when user on website check “Local” option it should hide reviews with class “Trustpilot” (already works) and then when user click “Load More” button it should load ONLY reviews with class “Local”. And I don’t know how to do this last part.

        I hope I explained more clearly. Sorry for my poor english.

  3. This is so helpful! When I added everything in its place (JS in header, HTML on page, code in functions) the Load More button appears with 9 items, but nothing loads when I click on it. The Chrome dev console outputs

    Uncaught ReferenceError: my_repeater_show_more is not defined
    at :1:2
    (anonymous) @ VM776:1

    Do you know why this might be?

    1. It sounds like you’re not calling the JS file, or maybe calling the JS code before it is loading the jQuery scripts.

      Let me know if you need further instructions… Happy to help.

  4. Hi, is there any way to fetch images from one ACF gallery via ajax. Acutlley I have 100 icons in one ACF gallery. I want to display 12 images on first load then show other 10 images via load more button. Please guide how we can accomplish this

  5. Its great tutorial and its working perfectly.
    It would be great, if you can create another tutorial for loading the ACF gallery images on scrolling without clicking the “Load more” button.

  6. i have 12 rows on my acf repeater, i tried the scripts but when i click load more instead of showing the last 2 rows it showing the same first 10 rows i set on $number. can you help me on this one please?

  7. If I were to add two of these to a single page, which parameters on the second one need to be modified to be different from the first one?
