Form Validation

Recommended Posts

Hi All,

 

Would anyone know an easy way to validate that a form entry has been entered once submitted. Ie.  I have 300 questions in a form, which are radio buttons, ie true and false.

Is there any php code that will say "you have not answered question 2"  etc...  if they leave questions blank.?

Thanks

Finto

<!--html page--> 
<form method="post" action="">
    <input type="checkbox" name="c1" value="true">
    <input type="checkbox" name="c2" value="true">
    .....
</form>

Now php page

  <?php
    //you have 300 question so u can use just a for loop
     for($i=1;$i<=300;$i++){
       if($_POST['c'.$i] == 'true'){
          echo "you have answered question ".$i;
       }else{
          echo "you have not answered question ".$i;
      }
    }
  ?>
