Image alt text in Repeater fields

  • Hi Everyone,

    I’m having trouble retrieving the alt text from slideshow images in an ACF Repeater field using a foreach loop. $image[‘alt’] is not working because of this foreach loop. The repeater field is called ‘slideshow’ and the sub field is called ‘foto’. The code I’m using now gives me the alt text from the featured image in WordPress, which is a thumbnail image, but I like to get the alt text from the slideshow images itself. I just can’t get it to work.

    Here’s my code:

    <div class="row">
    	<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
    	<div class="col-md-8">
    		<div class="main-content">
    			<?php $the_query = new WP_Query('post_type=projecten&posts_per_page=-1'); ?>
    			<div id="carousel-projecten" class="carousel slide" data-ride="carousel" data-interval="6000">			        	
    			<!-- Wrapper for slides -->
    			<div class="carousel-inner" role="listbox">
    					$slides = get_field('slideshow');
    					$image_id = get_post_thumbnail_id();
    					$image_url = wp_get_attachment_image_src($image_id, 'image-size', true);
    					$image_meta = get_post_meta($image_id, '_wp_attachment_image_alt', true);				
    					if($slides) {
    						$pp = 0;
    						foreach($slides as $s) {
    							if ($pp == 0) { $klasse = 'item active'; }
    							else { $klasse = 'item'; }
    								echo '<div class="'.$klasse.'">';
    								echo '<img src="'.$s['foto'].'" alt="'.$image_meta.'" />';
    								echo '</div>';
    			</div><!-- end wrapper for slides -->
    			<!-- Controls -->
    			<a class="left carousel-control" href="#carousel-projecten" role="button" data-slide="prev">
    				<span class="glyphicon glyphicon-chevron-left"></span>
    				<span class="sr-only">Previous</span>
    			<a class="right carousel-control" href="#carousel-projecten" role="button" data-slide="next">
    				<span class="glyphicon glyphicon-chevron-right"></span>
    				<span class="sr-only">Next</span>
    			</div><!-- end carousel-homepage -->
    	<?php endwhile; endif; ?>

  • Hi James,
    Thanks for your reply. According to the documentation, the example you’re giving is used with ACF Gallery, but is this applicable to ACF Repeater as well? I have an ACF with about ten custom fields and one repeater field (slideshow) with just images (foto), used for the slideshow. The alt text I need is from the images within the repeater field. My clients have to fill in the alt text for every image they upload and the code has to fetch this alt text.
    I think you’re right about the array, but I don’t know how to code this.
