I have a custom post type that has a custom field for a gallery images. I was trying to use some of your previous documenation to output list of image IDs that I can place in a shortcode for another plugin to use.

I tried these https://toolset.com/forums/topic/add-ids-of-repeating-images-to-gallery/ and https://toolset.com/forums/topic/id-like-to-make-a-gallery-from-images-added-in-a-post-type/ without success

custom field is slugged as gallery-image and I was trying to use this shortcode in the post for displaying.

[get_image_id postid="[wpv-post-id]" fieldslug="gallery-image"] - this only returned one ID, and there are 5 plus images in most of the posts

[get_image_ids_repeating post_id="[wpv-post-id]" field="gallery-image"] - nothig is returned

Hi Larry,

Thank you for getting in touch.

Assuming that your field is a Types field then you will need to do it like this.

[get_image_id postid="[wpv-post-id]" fieldslug="wpcf-gallery-image"]

Adding the wpcf- prefix to the field slug.

Please let me know if this helps.
Thanks,
Shane

Shane this only produces the IP for the post I believe and not each of the gallery images. This code only brings back one ID "350",

[get_image_id postid=”350″ fieldslug=”gallery-image”]
[get_image_id postid=”350″ fieldslug=”wpcf-gallery-image”]

Here's a sample page link

I want it to bring back all of these IDs.ids="362,361,360,359,358,357,356" for example

Hi Larry,

Did you add the corresponding code to the Toolset custom code section in Toolset -> Settings -> Custom Code?

If you didn't please add the following code there and ensure you click on the activate button once you've added it.

 // Add Shortcode
function get_image_id( $atts ) {
 global $wpdb;

    // Attributes
    $atts = shortcode_atts(
        array(
            'field' => '',
            'id' => ''
        ),
        $atts
    );

    $image_urls = get_post_meta($atts['id'],$atts['field']);
    $id_list = array();
 	foreach ($image_urls as $image_url) {
 		if(!empty($image_url)){
	    		 $attachment = $wpdb->get_col($wpdb->prepare("SELECT ID FROM $wpdb->posts WHERE guid='%s';", $image_url )); 
	    		 array_push($id_list, $attachment[0]);
	    	 }
   	 	}
 	 	
 return implode(",", $id_list); 
 
}
add_shortcode( 'get_image_id', 'get_image_id' );

Currently your shortcode isn't rendering on the frontend.

Thanks,
Shane

Yes I have this code in Code Snippets.

I'm still only getting this returned

[get_image_ids_repeating post_id=”350″ field=”gallery-image”]

Hi Larry,

The shortcode name that you are using is incorrect.

The correct format is.

[get_image_id postid="[wpv-post-id]" fieldslug="wpcf-gallery-image"]

What you have now is.

[get_image_ids_repeating post_id="350″ field="gallery-image"]

Please change it to the correct format and let me know if it starts working.

Thanks,
Shane

Sorry, Shane. I appreciate the help, but this isn't getting me where I need to be. I want to generate these IDs to convert this:

[gallery columns="6" ess_grid_gal="project-thumnail-slider" ids="362,361,360,359,358,357,356" orderby="rand"] (where these IDs are coming from the images my client uploaded to the gallery field as shown in the screen shot.

to:

[gallery columns="6" ess_grid_gal="project-thumnail-slider" ids="[get_image_id postid="[wpv-post-id]" fieldslug="wpcf-gallery-image"]" orderby="rand"]

Hi Larry,

Please allow me to have admin access to the website so that I can check on this for you.

I believe the issue here is that the wordpress Gallery shortcode doesn't allow a nested shortcode so you will need to modify the shortcode itself.

Let me know a sample page where I can test this out.

Thanks,
Shane

Hi Larry,

The shortcode should now be working.

I had to wrap the gallery shortcode inside the custom shortcode as well.

// Add Shortcode
function get_image_id( $atts ) {
 global $wpdb;
 
    // Attributes
    $atts = shortcode_atts(
        array(
            'field' => '',
            'id' => ''
        ),
        $atts
    );
 
    $image_urls = get_post_meta($atts['id'],$atts['field']);
    $id_list = array();
    foreach ($image_urls as $image_url) {
        if(!empty($image_url)){
                 $attachment = attachment_url_to_postid($image_url);
                 array_push($id_list, $attachment);
             }
        }
    $list_of_id = implode(",", $id_list);
  	return do_shortcode("[gallery columns='6' ess_grid_gal='project-thumnail-slider' ids='".$list_of_id."' orderby='rand']");
  
}

add_shortcode( 'get_image_id', 'get_image_id' );

So the final code to run this would be [get_image_id id="[wpv-post-id]" field="wpcf-gallery-image"]

Please let me know if this helps.
Thanks,
Shane
