html onclick won't trigger php function

Question

I have a button that's supposed to call a php function when it's called.

I've tried onClick, onclick, onclick="",and some other variations.

<input  type="submit" name="test" id="test" value="Save" onclick="<? 
       php echo click(); ?>" /><br/>

I just want it to get the onclick and trigger the php function.

Answer 1

The onclick attribute in HTML calls Javascript functions, not PHP functions.So you can use JS. Otherwise you can use the html for tag and use GET/POST method to call php function on click of the button in order to get it done.

The html code to be used.

<form action="" method="post">
  <input type="submit" name="test" value="Save" />
</form>

This is your php code

<?php
       if($_SERVER['REQUEST_METHOD'] == "POST" and isset($_POST['test']))
      {
          click();
      }
      function click()
      {
          echo "Clicked me!";  
      }
  ?>
