How to display Loop query that contains the same custom_field value as the curre

Hi Kevinbk,

To clarify, are you using a Query Loop Block?

If so, you can create a Shortcode to retrieve your custom field, and then use that shortcode in your Query Loop.

By default, WordPress uses the post meta of the actual Page/Post where the Loop is in for Shortcodes in Query Loops.

Reference: https://docs.generatepress.com/article/creating-a-shortcode/

You can add a Shortcode Block inside a Query Loop. Reference: https://wordpress.org/documentation/article/shortcode-block/

Hi there,

you can use the generateblocks_query_loop_args filter to check set a Query Loop with your-css-class to show posts that have a matching $meta_key that contains your your_custom_field_key

add_filter( 'generateblocks_query_loop_args', function( $query_args, $attributes ) {
   
    if ( ! is_admin() &&
        ! empty( $attributes['className'] ) &&
        strpos( $attributes['className'], 'your-css-class' ) !== false
    ) {
        $post_id = get_the_ID();
        $meta_key = 'your_custom_field_key';
        $current_post_custom_field = get_post_meta($post_id, $meta_key, true);

        return array_merge( $query_args, array(
            'meta_query' => array(
                array(
                    'key' => $meta_key,
                    'value' => $current_post_custom_field,
                    'compare' => '='
                )
            )
        ) );
    }
 
    return $query_args;
 
}, 10, 2 );

hmmm…. complicated.
If you had a custom field, which stores the name of the custom field that you set in the $meta_key variable then i suppose you could do:

add_filter( 'generateblocks_query_loop_args', function( $query_args, $attributes ) {
   
    if ( ! is_admin() &&
        ! empty( $attributes['className'] ) &&
        strpos( $attributes['className'], 'your-css-class' ) !== false
    ) {
        // set the name of the custom field that stores your custom field name
        $custom_field_choice = 'your_custom_field_choice_name';
        $post_id = get_the_ID();
        // load the $meta_key with the value of $custom_field_choice
        $meta_key = get_post_meta($post_id, $custom_field_choice, true);
        // get the current post meta of the chosen meta_key
        $current_post_custom_field = get_post_meta($post_id, $meta_key, true);

        return array_merge( $query_args, array(
            'meta_query' => array(
                array(
                    'key' => $meta_key,
                    'value' => $current_post_custom_field,
                    'compare' => '='
                )
            )
        ) );
    }
 
    return $query_args;
 
}, 10, 2 );

Custom Meta parameters are something we look to add in the future.
But they can be super complicated due to various comparisons and nested arrays etc. and everybody seems to want something different 🙂

For now it requires code. Tomorrow it may not.

What do you mean everyone wants something different?

The use cases for a WP_query are many and varied. Possibility an uncountable amount of variations.
And we want to add a UI that covers as many cases as possible. Which we will address in a future update. But it will be a Pro feature, as these kinds of requests are custom development.

Are you a GB Pro user? as that has the Exclude -> Current Post arg ?
