Cant pass this quiz for some reason?

Below the first if statement, write a conditional statement to test if the my_plugin_hidden_field input field has been submitted.

function my_plugin_options_page() {

    if (!current_user_can('manage_options')) {
        wp_die('You do not have sufficient permissions to access this page.');
    }

      if ( !isset( $my_plugin_hidden_field ) || $my_plugin_hidden_field == '' ) {

}

?>

the second if statement is what I did.

I haven't taken the course but based on that PHP function $my_plugin_hidden_field is not a defined variable. I think form submissions end up populating the $_POST superglobal so perhaps this is what it's asking?

if(isset($_POST['my_plugin_hidden_field'])) {
  // ...
}

You should write these code:

<?php

function my_plugin_options_page() {
  if (!current_user_can('manage_options')) {
    wp_die('You do not have sufficient permissions to access this page.');
  }
  if (isset($_POST['my_plugin_hidden_field'])){
  }
}

?>
