Hi John,
So there’s no more warning, and if I print_r on attachments I get:
Array ( [0] => Array ( [title] => Image 0 [image] => Array ( [attachment_id] => 1653 ) ) [1] => Array ( [title] => Image 1 [image] => Array ( [attachment_id] => 1652 ) ) [2] => Array ( [title] => Image 2 [image] => Array ( [attachment_id] => 1651 ) ) [3] => Array ( [title] => Image 3 [image] => Array ( [attachment_id] => 1650 ) ) [4] => Array ( [title] => Image 4 [image] => Array ( [attachment_id] => 1649 ) ) [5] => Array ( [title] => Image 5 [image] => Array ( [attachment_id] => 1648 ) ) )
It looks like the correct data is being returned but there are still no images loading in gallery field. Just checking that I’ve understood you correctly, this is the ammended snippet:
function build_gallery_from_rs($value, $post_id, $field) {
if (!empty($value)) {
// already has a value
return $value;
}
// does not have a value, build value from slider attachments
global $wpdb;
$table = $wpdb->prefix . 'new_royalsliders';
$id = get_field('media_gallery_slider', $post_id, false);
$slider_data = $wpdb->get_results( $wpdb->prepare("SELECT * FROM $table WHERE id=%d", $id), ARRAY_A );
// Build image array
//$value = array();
if ($slider_data) {
foreach ($slider_data as $slide) {
$attachments = json_decode($slide['slides'], true);
//print_r($attachments);
if ($attachments) {
foreach ($attachments as $attachment) {
$value = $attachment['attachment_id'];
}
}
}
}
return($value);
}
Many thanks again!
