I'm stuck implementing load next set of posts in WordPress with isotope masonry layout. It's just not triggered for appended elements and I can't figure out why. If someone could point me in right direction I would appreciate.
jQuery AJAX function
function load_content( args ) {
$container = $('#container-async');
$status = $('.status');
$.ajax({
url: ajax_url,
data: {
action: 'do_load_posts',
nonce: nonce,
args: args
},
type: 'post',
dataType: 'json',
success: function( data, textStatus, XMLHttpRequest ) {
$items = data.posts;
if ( args.action === 'filter') {
/**
* Replace items
*/
$container.imagesLoaded( function() {
$container.isotope({
itemSelector: '.grid-item',
percentPosition: true,
masonry: {
columnWidth: '.grid-sizer'
}
});
$container.html( $items ).isotope( 'appended', $items, function() {
console.log('inserted');
});
});
}
else {
/**
* Append items
*/
$container.imagesLoaded( function() {
$container.isotope({
itemSelector: '.grid-item',
percentPosition: true,
masonry: {
columnWidth: '.grid-sizer'
}
});
$container.append( $items ).isotope( 'appended', $items, function() {
console.log('appended');
});
});
}
},
error: function( MLHttpRequest, textStatus, errorThrown ) {
$status.toggleClass('active');
}
});
}
WordPress AJAX:
function ajax_do_load_posts() {
// Verify nonce
if( !isset( $_POST['nonce'] ) || !wp_verify_nonce( $_POST['nonce'], 'nonce' ) )
die('Permission denied');
$response = [
'status' => 500,
'posts' => 0,
];
$filter = $_POST['args'];
$type = get_post_type_object( $filter['type'] );
$args = [
'post_type' => sanitize_text_field($filter['type']),
'paged' => intval($filter['page']),
'posts_per_page' => $filter['qty'],
];
$qry = new WP_Query($args);
if ($qry->have_posts()) :
ob_start();
while($qry->have_posts()) : $qry->the_post(); ?>
<div class="grid-item col-xs-12 col-sm-6 col-md-4 col-lg-3">
<?php get_template_part('templates/loop', 'card' ); ?>
</div>
<?php endwhile;
$response = [
'status' => 200,
'posts' => ob_get_clean(),
];
endif;
wp_reset_query();
wp_reset_postdata();
die(json_encode($response));
}
add_action('wp_ajax_do_load_posts', 'ajax_do_load_posts');
add_action('wp_ajax_nopriv_do_load_posts', 'ajax_do_load_posts');
Items are inserted or appended into container but masonry is triggered only on items that are already there on page load.
I have googled around and tried various solutions but none of them work, neither with isotope or masonry jquery plugin.
