ACF fields on post type list location not saving

Hello,

Thanks for the feedback, and sorry for the late asnwer, I was kinda busy with the latest big patch lately.

This is not normal. I just ran a simple test, and it works fine on my end. Here is video of my test.

Can you try this test on your setup? Here is the export code of the Field Group. You can add to your theme’s functions.php file. The Test field should be displayed on the “Pages” WP Admin menu.

add_action( 'acf/init', function() {
    
    acf_add_local_field_group( array(
        'key' => 'group_6632ba2a8dbee',
        'title' => 'Page List',
        'fields' => array(
            array(
                'key' => 'field_6632ba2ae1863',
                'label' => 'Textarea',
                'name' => 'textarea',
                'aria-label' => '',
                'type' => 'textarea',
                'instructions' => '',
                'required' => 0,
                'conditional_logic' => 0,
                'wrapper' => array(
                    'width' => '',
                    'class' => '',
                    'id' => '',
                ),
                'default_value' => '',
                'acfe_textarea_code' => 0,
                'maxlength' => '',
                'rows' => '',
                'placeholder' => '',
                'new_lines' => '',
            ),
        ),
        'location' => array(
            array(
                array(
                    'param' => 'post_type_list',
                    'operator' => '==',
                    'value' => 'page',
                ),
            ),
        ),
        'menu_order' => 0,
        'position' => 'side',
        'style' => 'default',
        'label_placement' => 'left',
        'instruction_placement' => 'label',
        'hide_on_screen' => '',
        'active' => true,
        'description' => '',
        'show_in_rest' => 0,
    ) );
    
} );

If the field isn’t correctly saved, then you might have some custom code, either in your theme or a third party plugin which interfere with the saving logic.

In order to isolate the issue, I would recommend clone your website on a development / staging environment using Duplicator, or your hosting backup solution. Then try to disable all your plugins one-by-one (at the exception of ACF Pro & ACF Extended) until you find which one cause the issue.

If the problem persists, try switch to the native WP Twenty Twenty Two theme, to make sure you don’t have any custom code in your theme which would break the feature.

In all cases you should be able to confirm it works like I did, by setting up a clean WP install with ACF Pro + ACF Extended only.

Let me know if you managed to fix the issue!

Thanks!

Regards.
