Question

I need to validate errors before it goes to action url of the form.
When i click submit it goes to the /test/policy.php even though there are errors.
I want it to go there only if there are no errors in my form.
Here is my code so far:

// Create an empty array to hold the error messages.
$arrErrors = array();
//Only validate if the Submit button was clicked.
if (!empty($_POST['submit']))
 {

      // Each time theres an error, add an error message to the error array
      // using the field name as the key.
      if (empty($_POST['first_name']))
          $arrErrors['first_name'] = '<br><font color="red">Please provide your first name.</font>';
      if (empty($_POST['last_name']))
          $arrErrors['last_name'] = '<br><font color="red">Please provide your last name.</font>';
      if (empty($_POST['business_name']))
          $arrErrors['business_name'] = '<br><font color="red">Please provide your business name.</font>';
 }


      // If the error array is empty, there were no errors.
      // Insert form processing here.

      if (count($arrErrors) == 0)
      {


        $first_name=cleaninput($_POST['first_name']);
        $last_name=cleaninput($_POST['last_name']);
        $business_name=cleaninput($_POST['business_name']);
        //Insert the details into database

      }
      else
      {

        // The error array had something in it. There was an error.
        // Start adding error text to an error string.
        $failure_message= "There was an error in the form";

        $strError="";
        foreach ($arrErrors as $error)
        {
           $strError .= $error;
        }

      }
    }
 ?>



<tr>
   <td>
   <? if(!empty($success_message))
      {
        echo "<center><font color='blue'><b>".$success_message."</b></font><br>";
      }
      if(!empty($failure_message))
      {
         echo "<center><font color='red'><b>".$failure_message."</b></font><br>";
      }
   ?>

You could leave the action blank and then, after validating, you can redirect to /test/policy.php with header.

if (count($arrErrors) == 0) {  
    header('Location: /test/policy.php');  
}
