This is known as array dereferencing and is only available in PHP 5.4+ To support older versions, you need to assign the array, and then access the index: $data = get_post_meta( $product_id, ‘_product_image_gallery’ ); $gallery_pictures_id = $data[0]; Having said that, in your case use the third argument “single”: $gallery_pictures_id = get_post_meta( $product_id, ‘_product_image_gallery’, true );
Since you are storing an url for each image you can create a query to get the id of the attachment based on the guid: global $wpdb; $ids = array(); foreach ($images as $image_url) { $ids[] = $wpdb->get_col($wpdb->prepare(“SELECT ID FROM $wpdb->posts WHERE guid=’%s’;”, $image_url)); } Another way would be to simply store the ID rather … Read more
Meta boxes are saving data at each post ($post_id) $value = get_post_meta($post_id, ‘name’, true); name=”dbt_text” or ‘dbt_text1’ so $value = get_post_meta($post_id, ‘dbt_text’, true); $value1 = get_post_meta($post_id, ‘dbt_text1’, true); ~ more info on get_post_meta
use get_the_ID() to get post id
I am not sure what ‘be_price’ is for, but I think your $args should look like this: $args = array( ‘post_status’ => ‘publish’, ‘posts_per_page’ => ‘150’, ‘cat’ => $cat_id, ‘meta_key’ => ‘popularity’, ‘order’ => ‘DESC’, ‘orderby’ => ‘meta_value_num’, ‘meta_query’ => array( ‘key’ => ‘gone’, ‘value’ => ‘1’ ) );

You have a structural problem with your data. Serialized data in the database is terrible if you need to search over pieces of that serialized data. There is no reliable, efficient, and certainly no easy, SQL query to search over serialized data. “serialization” is a PHP mechanism. It isn’t SQL. To the database that is … Read more
If its your own custom post type you should know the field names? Iterate through the fields – or better just get the required field – an then use the attachment Id with wp_get_attachment_image_src. http://codex.wordpress.org/Function_Reference/wp_get_attachment_image_src Chech the codex for further examples and Google for “WordPress custom post type fields”.
I tried your code and it works: I changed the wp_verify_nonce function, because that wasn’t working for me. I added an action instead of what it had. Now, for this to work, you have to create a nonce field with a code like this, of course that you can change the names if you want. … Read more
