title: How to execute a function in wordpress?
body: <p>Hi i am new to wordpress , I am trying to validate a value. So each time the page loads the function must execute, is it possible to write it in my functions.php?</p>
  
  <pre><code>function checknewusr()
  {
     //My Code;
  }
  add_action('????', 'checknewusr');
  </code></pre>
  
  <p>I am not aware of the action hook to give on that area so that my function will execute every time i load a page.</p>
