Tell us what you are trying to do?
I want to grab the IDs of an image field with multiple instances to create a masonry gallery with a shortcode from another plugin.

Is there any documentation that you are following?
I tried to follow this: https://toolset.com/documentation/user-guides/custom-content/create-image-galleries-using-toolset-and-custom-fields/
But there is some Info missing how to use this with external galleries

What is the link to your site?

Hi Peter,

Thank you for getting in touch.

You can actually use the custom shortcode below in order to get this.

    // 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' );

Add it to your Toolset->Settings -> Custom Codes and then activate it.

To use it you will do this [get_image_ids field='field-slug' id='[wpv-post-id]']

Replace the field-slug with the actual slug of the repeatable field.

Please let me know if this helps.
Thanks,
Shane

Unfortunately this doesn't work. I put the right slug into the shortcode so it is: [get_image_ids field='taschengaleriebild' id='[wpv-post-id]']
Still doesn't put out the gallery right :/ the code is active.

Hi Pete,

If you were to place the shortcode outside your masonry gallery shortcode does it work ?

Unfortunately if the shortcode is unable to accept another shortcode as a parameter then there is nothing we can really do.

Please let me know if the shortcode that i've provided returns the ID's of the images.

Thanks,
Shane

[peterZ]

The shortcode isn't getting executed at all.
I changed every get_image_id to get_image_ids in the custom code to match the shortcodes name - didn't work either.

Hi Peter,

Would you mind allowing me to have admin access to the site to check on this for you ?

The private fields have been enabled for your next response.

Thanks,

Hi Peter,

I've made some adjustments to the code and it should now be returning the ID's of the images.

However it seems that your masonry grid shortcode isn't able to handle the shortcode as a parameter. There isn't anything we can do at this point since the code now provides the ID's for the item.

Thanks,
Shane

Hi Shane,
yes the IDs are returned now. But with the triple shortcode it doesn't work. Can I define variables inside a view?

[Shane]

Hi Peter,

Here is the final shortcode that i've modified to include the current post ID.

// Add Shortcode
function get_image_ids( $atts ) {
 global $wpdb;
    // Attributes
    $atts = shortcode_atts(
        array(
            'field' => '',
            'id' => get_the_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);
             }
        }
         
 	return implode(",", $id_list);   
}
add_shortcode( 'get_image_ids', 'get_image_ids' );

It is able to still take the ID as a parameter but if an ID isn't provided it gets the ID from the view loop. As you can see it still doesn't work. This definitely means the parameter isn't able to handle shortcodes.

Thanks,
Shane

Hi Shane,

the parameter is able to handle shortcodes. I am doing that in other ones. But having a shortcode inside a shortcode inside a shortcode doesn't work.
That is why I am asking if I can use variables in Toolset to help myself out here.

Thanks!

[Shane]

Hi Peter,

As it is right now the shortcode doesn't take another shortcode as a parameter.

The custom [get_image_ids] shortcode is able to now function without the ID parameter.

You can use it like this [get_image_ids field='wpcf-my-images']

This is what is now added to the masonry shortcode in this format and it still doesn't work. Is it that it is expecting the shortcode to just be [get_image_ids]

Please let me know.
Thanks,
Shane

This is what it looks like now.

[dss_masonry_gallery _builder_version="4.3.4" images='[get_image_ids field="wpcf-taschengaleriebild"]' hover_enabled="0"][/dss_masonry_gallery]

Hi SHane,

why are you ignoring my question? I am asking if I can use variables indisde the view. Then I can work around this problem very easily.

Thanks,
Peter

[Shane]

Hi Peter,

I'm not ignoring the question. However when you say variable are you referring to PHP variables? if that is so then no you are not able to do this directly.

The variable would need to be wrapped in a shortcode for you to be able to use it in views.

Though what you can do so that we have 100% clarity is provide an example of how you want your masonry shortcode to get the values. As you say you want to use variables but could you provide an example of what this would look like in the masonry shortcode ?

However what seems to be happening is that the masonry isn't accepting the shortcode.

Another solution I can think of is to return the masonry shortcode inside the custom shortcode that i've created. So we would pass the raw ids that we get from the database directly into the shortcode and return the results of the masonry grid code. All this as a single combined shortcode.

So instead of this .

[dss_masonry_gallery _builder_version="4.3.4" images='[get_image_ids field="wpcf-taschengaleriebild"]' hover_enabled="0"][/dss_masonry_gallery]

You will just have a custom shortcode.

[cust_masonry _builder_version="4.3.4" images='[get_image_ids field="wpcf-taschengaleriebild"]' hover_enabled="0"]

Then we will rebuild the dss_masonry_gallery shortcode inside the cust_masonry shortcode when we render it using the do_shortcode() function.

Please let me know what you think of this as it should be able to work for your case.

Thanks,
Shane

Hi Shane,
yes, I meant PHP-variables. Unfortunate, that I can't use them.

Yes, this would actually be the solution I would implement now.
I'll do that, thank you.
