title: How can I get data from Ninja Forms to appear in frontend?
body: <p>I just know a little bit about Javascript, I'm not a programmer yet.
  I created a <code>Ninja Forms</code> to be used in my Wordpress site. When a user fills out the 4 fields of the form and press <kbd>Submit</kbd>, I need those data to appear always in the frontend ( in their 4 specific places I've created in html), and the last one submitted overwrite to the previous one.</p>
  
  <p>Ninja is saving the data in wp_postmeta like this:</p>
  
  <pre><code>    **meta_key**   **meta_value**
      _field_12     (the first of the values I want appear in frontend)
      _field_13     (the second one)
      _field_14     (the third one)
      _field_15     (the fourth one)
      _form_id      1 (always the same value)
      _seq_num      3 (increase 1 every time Submit is pressed)
  </code></pre>
  
  <p>How can I do it?
  I know is out of my range without PHP knowledge but, can someone give me some trick? Is there a plugin to get it?</p>
  
  <p>Help, please</p>
