I am struggling in making tables relationships work. Is there any simple howto to explain it?

Thanks,
NunoS

I’m working with ACF Pro and have a parent CPT “Song” that relates to a child post type of “Chapter.” In the single post song page, I can see the URL from the parent in a higher level container, but when I use a loop grid and attach the video box to it, even though the ACF URL field is visible to the video box link field, it doesn’t resolve. Somehow that data is lost to the video component. The fallback is always shown instead of the link in the parent.

My relationship is working with the post_object ID in the higher containers – in other words the parent data is exposed within the chapter output.

I can put the URL in the chapter data and it works, but that would be not so DRY as it would repeat for every chapter related to a song. Am I missing something?

Thanks for your support,
John

Is there another setting I am missing somewhere?

Where category ID is 50 and field name is education_requirements

But can’t get this working, is this even possible?

<?php 
function add_custom_product_data_contents( $pro_class_obj, $product, $post ) {
    //prnt_r($product->get_id());die;
    $hh = get_post_meta($product->get_id() , 'whats_onz' );
    //print_r($hh);
   ?>

   
      <div role="tabpanel" class="tab-pane fade" id="see-more"> <!-- just make sure tabpanel id should replace with your added tab target -->
       <div class="row-padding">

//what should I do here to search for users?          
 <div class="form-group">
               <label class="control-label col-sm-3 col-md-3">More:</label>
               <div class="col-mzd-6 col-sm-9">
                   <input type="search" name="whats_onz" class="form-control" value= <?php print_r($hh[0]) ?> />
             
                
               </div>
           </div>
       </div>
   </div>
   <?php
}
add_action( 'wcmp_product_tabs_content', 'add_custom_product_data_contents', 10, 3 );

Thanks so much for any help,
Kind regards

I’m new to wordpress and pods. So please indulge me: After creating 6 custom taxonomies I always get an error, when I’m adding the correspondent relationship field for the seventh one. I always get the error message that the correspondent name “is reserved for internal purposes on WordPress or Pods. Please choose a different name”. I get the message in German directly in the modal view.

I tried several names (8 at least) some of them are just gibberish that are certanily not reserved for any purpose whatsoever. I always get the same error. Could it be that there is a conflict with pods and Astra, the theme I use? Or do I have to change some Astra settings?

I’m using the pods version 2.9.19 and for Astra I use Astra Pro Version 4.1.5 .

I can reproduce the error.

I noticed logging into the database that the users showing up seem to have the role listed under wp_capabilities in the user meta where those that don’t don’t seem to have that, but instead have my-custom-db-name_capabilities.

A couple of other things; during testing I had switched on and then off the option to store the data in it’s own col. Also, I’ve changed the sign up process, a user now registers a membership from a plugin called paidmemberships pro https://www.ads-software.com/plugins/paid-memberships-pro/ which also attaches roles to their user via a plugin, including the UM role in question. Could this be an issue? I was using S2 Member https://www.ads-software.com/plugins/s2member/.

Now when I check the roles in admin, all seems to work exactly as it should, and the rest of the UM outcomes related to these roles work too, for example the correct profile forms display, the correct redirects happen for the role type etc, the only problem is that not all users with the role show up as options in this search form in the ‘edit profile’ screen after activating this code.

Thanks in advance, I just can’t work out what I’m missing!

		<h2>Enter a relationship in the following format</h2>
		<pre>meta_key|type|slug|link</pre>
		<h4>meta_key</h4>
		<p>This is the meta key of the field generated in the UM Form Builder.<br>
			<strong>Important:</strong> The field type should be either <code>dropdown</code> or
			<code>multiselect</code>, and "relationship" should be added in the first line of the options field of the
			Form Builder.</p>
		<h4>type</h4>
		<p>This is type of item you are relating to - either <code>user</code>, <code>tax</code> or <code>post</code>.
		</p>
		<h4>slug</h4>
		<p>If your <code>type</code> is <code>user</code>, this value is the user role slug that will filter the options
			in the select area. Multiple user roles should be defined as a comma-seperated list eg.
			<code>admin,member</code>. Leave empty to add all user roles.<br>
			If your <code>type</code> is <code>tax</code>, this value is the taxonomy slug that will filter the options
			in the select area. A single taxonomy slug must be entered.<br>
			If your <code>type</code> is <code>post</code>, this value is the comma seperated list of post types slugs
			that filter the options in the select area.</p>
		<h4>link</h4>
		<p>Set this value to <code>true</code> if you want to hyperlink the users or posts in display mode on the
			profile, or <code>false</code> to disable hyperlinks. If your type is <code>user</code>, you can also use
			<code>avatar</code> here to display an avatar.</p>
		<h4>Examples</h4>
		<p><code>my_coach|user|coach|true</code></p>
		<p><code>fav_meal|post|recipes|true</code></p>

Why tables belonging to woocommerce and wordpress don’t have foreign keys in constraints tab? Even if I generate ER Diagram in DBeaver, the relationships don’t show. Even if I export database to SQL file i dont have Foreign Keys Constraints. Can I somehow get Woocommerce database ER Diagram with relationships shown? I am student and I need that for my project.
Thank for your help.
