Single Image in settings page to be added to a page or post custom field.

Hello Peter,

Thanks for the quick reply!

Yes it seems the first example is the right solution, I did check the doc, but their is no example for updating other fields

Does this look ok to you?

// Hook into rwmb_after_save_field action
add_action( 'rwmb_after_save_field', 'update_target_field', 10, 5 );
function update_target_field( $null, $field, $new, $old, $object_id ) {
    // Check if the saved field is 'image_of_town_1' and the object is a settings page
    if ( $field['id'] === 'image_of_town_1' && is_admin() && get_post_type( $object_id ) === 'settings_page' ) {
        // Update the target field (image_of_town) on the post/page with the image URL
        update_post_meta( 110, 'image_of_town', $new );
    }
}

Many thanks

Mick

Hello Peter,

Again thank you for the quick reply, unfortunately It did not populate it and still shows the add media button in the page custom fields 🙁 I did remove the condition as you advised so the new code is now:

// Hook into rwmb_after_save_field action
add_action( 'rwmb_after_save_field', 'update_target_field', 10, 5 );
function update_target_field( $null, $field, $new, $old, $object_id ) {
    // Check if the saved field is 'image_of_town_1' and the object is a settings page
    if ( $field['id'] === 'image_of_town_1' && is_admin() ) {
        // Update the target field (image_of_town) on the post/page with the image URL
        update_post_meta( 110, 'image_of_town', $new );
    }
}

Here is the display code output of the image_of_town_1 in Metabox just so you can see I am using the correct ID's:

This is a single image field in a tab in a settings page:

<?php // Displaying uploaded image: ?>
<?php $image = rwmb_meta( 'image_of_town_1', [ 'object_type' => 'setting', 'size' => 'thumbnail' ], 'mb-website-settings' ); ?>
<h3>Logo</h3>
<img src="<?= $image['url']; ?>">

<?php // or simpler: ?>
<h3>Logo</h3>
<?php rwmb_the_value( 'image_of_town_1', [ 'object_type' => 'setting', 'size' => 'thumbnail' ], 'mb-website-settings' ) ?>

Here is the single image field in the page custom field:

<?php // Displaying uploaded image: ?>
<?php $image = rwmb_meta( 'image_of_town', [ 'size' => 'thumbnail' ] ); ?>
<h3>Logo</h3>
<img src="<?= $image['url']; ?>">

<?php // or simpler: ?>
<h3>Logo</h3>
<?php rwmb_the_value( 'image_of_town', [ 'size' => 'thumbnail' ] ) ?>

I also double checked the ID of the page and it is 110.

Many thanks again for your support.

Kindest Regards

Mick

Hi Peter,

Still does not work for me for some strange reason. I used 2021 theme with only MB plugins installed and added the code the them function.php file.

Please see video for you to review:

Thanks Peter,

Just sent them to you now.

Many thanks

Hello Peter,

Thank you so much!

1. Doh, I must not have scrolled down far enough!

2. Ah ok, I was not to sure if to include it or not/or even the ID of the tab for the settings page haha.

Finally may I ask, is it possible to run that but without the page ID? Example, wherever there is a custom field named image_of_town on a post or page and the location_detailsimage_of_town_1 is saved it will update them all? Do I jusr remove the 110, from this string update_post_meta( 110, 'image_of_town', $new ); so it will read update_post_meta( 'image_of_town', $new );

Again many thanks for your help!
