title: WP-Members / How to update value of radio button value?
body: <p>I'm using WP-Members. And I'm using <code>wp_update_user</code> function to update value.
  When I try to update the "text" value, it is updated. Like this.</p>
  
  <pre><code>$test = array ( 'ID' =&gt; $id,'first_name' =&gt; $first_name);
  </code></pre>
  
  <p>But, when it comes to update the value of "radio", it didn't work.</p>
  
  <pre><code>$test = array ( 'ID' =&gt; $id,'plan' =&gt; $plan);
  </code></pre>
  
  <p>$plan is a string value</p>
  
  <p><a href="https://i.stack.imgur.com/RJIGa.png" rel="nofollow noreferrer">setting of the "plan"</a></p>
  
  <p>How can I update the radio button value?</p>
