How to create galleries for wordpress posts withou

Question

I want to create galleries for my posts working like this :

1. I choose pictures in wordpress post-new page and upload them
2. Wordpress creates an array of those images uploaded
3. And finally i use that array and put gallery into my single.php file

Actually woocommerce is using the exact thing as you see in the picture ( sorry i didn't have English wordpress installed )

any suggestions?

Answer 1

you can use the default gallery behavior to your need

• Insert a gallery in tour post, it will create a shortcode like

  [gallery ids="12,45,67,34"]
  

• override the default gallery shortcode function to not display it in your post

  remove_shortcode( 'gallery', 'gallery_shortcode' );
  add_shortcode( 'gallery', 'my_gallery');
  function my_gallery(){
      return '';
  }
  

• retrieve an array of images ids

  $post_content = get_the_content();
  preg_match('/\[gallery.*ids=.(.*).\]/', $post_content, $ids);
  if($ids){
      $array_id = explode(",", $ids[1]);
  }
