Hi,

I used CPT UI to create a custom post type. Then, I want to display on these custom posts a list of media (mainly pictures).

How can I display a field on media meta where I chose the custom posts where the media should be displayed ? Which field type should I use ?

Thanks,

David

Hi @sireagroup

I suggest you use the post object field and set the location rule to “Attachment <=> is equal to <=> All”.

I hope this helps 🙂

Hi,

Thank you for your answer.

This is what I tried before posting, but this way doesn’t retrieve anything. When I debug, this is empty …

Hi @sireagroup

Could you please share the code you used to debug it? If you need to get the value from an attachment, please check this page out: https://www.advancedcustomfields.com/resources/how-to-get-values-from-a-media-attachment/.

If you want, you can also use a gallery field on your custom post type so you can set which images you want to show up on that post.

Thanks 🙂

I paste this :

<?php   echo '<pre>';
    print_r( get_field('media-test')  );
echo '</pre>'; ?>

“media-test” is the name of the field displayed on a media in the my media library in the admin panel.
I selected a custom post displayed in the field, but when I use the code from post object in the PHP of my custom post single template, nothing is retrieved.

The gallery field is a good way, I will use it if the first option doesn’t work.

Hi @sireagroup

As stated in the link I gave you before, you need to pass the ID of the media as the second parameter of the get_field() function like this:

<?php
echo '<pre>';
    print_r( get_field('media-test', 99)  );
echo '</pre>';
?>

Where “99” is the ID of your media. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/how-to-get-values-from-a-media-attachment/.

I hope this helps 🙂

Finally I solved it !
Here is what I used, it works : https://www.advancedcustomfields.com/resources/querying-relationship-fields/.

but I have another problem :

The number of elements used in reverse query are medias, but I don’t know why i can only display 5 medias, no more. Does someone know why ?

Hi @sireagroup

I believe that’s because you have an option on your site that allows only five posts. In this case, you need to use the posts_per_page option like this:

$doctors = get_posts(array(
    'post_type' => 'doctor',
    'posts_per_page' => -1,
    'meta_query' => array(
        array(
            'key' => 'location', // name of custom field
            'value' => '"' . get_the_ID() . '"', // matches exaclty "123", not just 123. This prevents a match for "1234"
            'compare' => 'LIKE'
        )
    )
));

Hope this helps 🙂
