title: How to show custom data on custom post type admin screen edit page?
body: <p>I have created form for enquiry. When user fill this form then I am saving it into database as a custom post type. In backend I need to show extra information on custom post edit page. But did not find any hook. </p>
  
  <p>I have tried this code: </p>
  
  <pre><code>[![function add_extra_info_column( $columns ) {
      return array_merge( $columns, 
          array( 'sticky' =&gt; __( 'Extra Info', 'your_text_domain' ) ) );
  }
  add_filter( 'manage_posts_columns' , 'add_extra_info_column' );][1]][1] 
  </code></pre>
  
  <p>But it adds a new column in custom post. </p>
  
  <p>I need to show extra info when we click on edit page link for every post.</p>
