使用高级自定义字段库与媒体类别和Ajax

Question

Question: I have created a gallery using Advanced Custom Fields. All the images I have added into the gallery I have given a custom taxonomy (category) e.g. 'Fashion', 'Portraits' etc. I have listed all the terms above the gallery. I want to be able to click a term, e.g. Fashion, and for all the images with the term 'Fashion' to load in the image container below. Similar to https://demo.kaliumtheme.com/photography/. I am stuck with getting the images to load on the click of a term. Can you help?

Here's the code for the gallery:

        <?php $images = get_field('gallery');

        if( $images ): ?>
            <ul><div class="image__sizer"></div>
                <?php foreach( $images as $image ): $link = get_field('link', $image['ID']); ?>
                <?php $terms = get_the_terms( $image['ID'], 'category_media' ); ?>
                <?php if ( !empty( $terms ) ) : $term = array_shift( $terms ); ?>
                    <li class="<?php echo $term->term_id; ?>">
                        <div data-200-bottom="top: 0px;opacity:0%;" data--200-top="top:-250px;opacity:100%;" class="image__wrap">
                        <a href="<?php echo $image['url']; ?>">
                             <img src="<?php echo $image['sizes']['large']; ?>" alt="<?php echo $image['alt']; ?>" />
                        </a>
                        <div class="image__meta">
                            <span><?php echo $term->name; ?> - <?php echo $image['title']; ?></span> 
                        </div>
                        </div>
                    </li>
                <?php endif; ?>
                <?php endforeach; ?>
            </ul>
        <?php endif; ?>

The custom taxonomy is called 'category_media'. I was looking to use a function like this one below:

 function prefix_load_term_posts () {
    $term_id = $_POST[ 'term' ];
        $args = array (
        'term' => $term_id,
        'posts_per_page' => -1,
        'order' => 'DESC',
             'tax_query' => array(
              array(
                  'taxonomy' => 'category_media',
                  'field'    => 'id',
                  'terms'    => $term_id,
                  'operator' => 'IN'
                  )
              )
         );

    global $post;
    $myposts = get_posts( $args );
    ob_start ();  ?>

    <?php foreach ($myposts as $post):
    echo $images = get_field('gallery', $post->ID); ?>
    <?php endforeach; ?>

   <?php wp_reset_postdata(); 
   $response = ob_get_contents();
   ob_end_clean();
   echo $response;
   die(1);
    }

with this JQuery function:

<script>
function term_ajax_get(termID) {
jQuery("a.ajax").removeClass("current");
jQuery("a.ajax").addClass("current"); //adds class current to the category menu item being displayed so you can style it with css
jQuery('.image-container ul li').fadeOut();
jQuery("#loading-animation").show();
var ajaxurl = '<?php echo admin_url( 'admin-ajax.php' ); //must echo it ?>';
jQuery.ajax({
    type: 'POST',
    url: ajaxurl,
    data: {"action": "load-filter2", term: termID },
    success: function(response) {
        jQuery(".image-container ul").html(response);
        return false;
    }
});
}
</script>

However, no images are loading into the container. Can anyone help and tell me what I'm missing? It would be much appreciated, thanks!

Your question is not understood Try to give more details and shorten the code Do not let all the code give you just where you have a specific problem
