Hi!

And thanks in advance for your help.

I’m trying to update a input field of a settings page, when a user click on a button in the admin (wp_ajax_ hook function).

There I generate a json (it works) but I also want to update an input value with a value.

I don’t know if I can call rwmb_set_meta in this wp_ajax_action, or if I am using the correct syntax because I’m getting a 500 error.

I have tried this:
rwmb_set_meta( ‘generalsettings’, ‘idgeneratedcdn’, ‘value’, array( ‘object_type’ => ‘setting’ ));

and this
rwmb_set_meta( ‘generalsettings’, ‘idgeneratedcdn’, ‘value’);

What am I doing wrong? the place I call the funcion or rwmb_set_meta for a settings page?

Thanks!!

Hi,

The function rwmb_set_meta() will be included in the next release. At this time, please try to use the function update_option() to update the settings page option.

Here is the sample code
```
add_action( 'init', function() {
    $settings_page = get_option( 'generalsettings' ); // the settings page ID
    $settings_page['idgeneratedcdn'] = 1000; // the field ID
    update_option( 'generalsettings', $settings_page ); // update
} );
```
For more information, please follow the documentation https://developer.wordpress.org/reference/functions/update_option/
