It is not working for network setting page?

[faiyazalam]

I created a network setting page but it is not working.
When I submit it is showing 404 page.
To fix this I just remove the action name "options.php" from the form.
Now it is not saving data.

Yes, I encountered the same issue. The class is hard-coding options.php.

I tried changing line 531 in class.settings-api.php to:

<form method="post" action="<?php echo $_SERVER[ 'REQUEST_URI' ]; ?>">

...which I believe to be correct, but the settings are still not saving. I have to look at it more closely.

Well, including the above change, I got it to work with a total hack. Given this example...

I added something like this to manually update options when the page is submitted:

function __construct() {
  // ... other code ...

  // Update network options when form submit is detected
  if( isset( $_POST['option_page'] ) && $_POST['option_page'] == 'wedevs_basics' ) $this->save_network_options();
}

private function save_network_options() {
    if( $_POST[ 'wedevs_basics' ] ) {
      $options_array = [];
      foreach( $_POST[ 'wedevs_basics' ] as $option_name => $option_value ) {
        $options_array[ $option_name ] = $option_value;
      }
      update_option( 'wedevs_basics', $options_array );
    }
  }
}

NB! This is not ideal and the code above may contain errors. It is heavily modified from my own code, which has a bunch of extra logic and tabs. I included it in case you are desperate. Caveat emptor.

I'm not sure how to retrieve a value from wp_options from a sub-site since it always tries to get it from the site's own wp_options. Does anyone know? get_option() and the multisite variants didn't work for me. We can't save to wp_sitemeta for get_network_option() or whatever, else the settings page doesn't populate. So, you'll probably have to create another hack...

// Retrieve value from wp_options
private function get_wpsac_network_option( $section_id, $option_name ) {

  global $wpdb;
  $result = $wpdb->get_col( $wpdb->prepare( "SELECT option_value FROM {$wpdb->base_prefix}options WHERE option_name = '%s'", $section_id ) );

  if( !isset( $result[0] ) || !is_serialized( $result[0] ) ) return '';
  $result = unserialize( $result[0] );

  return isset( $result[ $option_name ] ) ? $result[ $option_name ] : '';

}

// Example usage:
echo $this->get_wpsac_network_option( 'wedevs_basics', 'my_field_name' );

Again, not tested for errors... There is a better way, I just don't feel like finding it right now.

Good luck! Haha

@dmhendricks
To save time, I have not used this plugin for network admin setting page. I am using this only for admin setting page.
Hope the author will fix this soon.

Thanks for your response.

@faiyazalam - Carbon Fields is about the only custom fields framework I've observed that supports network settings pages. It is available as a plugin and also via Composer.
