I've created a form for my plugin settings and set the action attribute of the form to "options.php" but when I submit the form I get "ERROR: options page not found."
add_action('admin_menu', 'create_menu');
function create_menu(){
// add menu page
add_menu_page(
'Basic Plugin Menu Page',
'Bp Menu',
'manage_options',
'bp_menu',
'bp_menu_cb',
plugins_url('images/wordpress.png', __FILE__),
76 );
// add submenu page
add_submenu_page(
'bp_menu',
'Besic Plugin Submenu',
'Options',
'manage_options',
'bp_options',
'bp_options_cb' );
add_action('admin_init', 'bp_register_settings_cb');
} // end add_menu
function bp_register_settings_cb(){
// - register_setting( $option_group, $option_name, $sanitize_callback );
register_setting('bp-settings-group', 'bp_options', 'bp_options_sanitize');
} // enb bp_register_settings_cb
function bp_options_sanitize($input){
$input['name'] = sanitize_text_field($input['name']);
$input['email'] = sanitize_email($input['email']);
$input['url'] = esc_url($input['url']);
return $input;
} // end bp_options_sanitize
function bp_menu_cb(){ ?>
<div id="wrap">
