Condition Checking

Hi All,

I've created a form, whereby if fields are not filled in then the form should not be processed:

PHP Code:


<?php



// ** If Submit is hit do your stuff **

    if (isset($_POST['Submit'])) {

    

     $your_name = $_POST['your_name'];

     $your_email = $_POST['your_email'];



// ** Check for Required Fields with IF statements **

       if (empty($your_name)){

        $error = "** You forgot to enter your name! **"; 

    }  else if (empty($your_email)){

        $error = "** Error: You forgot to enter your email! **";

    } 

}

?>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>Submit_test</title>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

</head>



<body>

<form action="process_submission.php" method="POST" enctype="multipart/form-data">

<?php echo $error?>

  <table width="475" border="0" cellpadding="0" cellspacing="5" bgcolor="FFFFFF">

    <tr> 

      <td colspan="2" class="formtext"><strong>Personal Details</strong></td>

    </tr>

    <input type=hidden name=subject value="News Submission Form">

    <tr> 

      <td width="239" align="left" valign="middle" class="formtext">Name:</td>

      <td align="left" valign="middle"> <INPUT TYPE="text" NAME="your_name"></td>

    </tr>

    <tr> 

      <td class="formtext">Address:</td>

      <td><INPUT TYPE="text" NAME="your_address"> </td>

    </tr>

    <tr> 

      <td> </td>

      <td><input type="submit" name="Submit" value="Submit"> </td>

    </tr>

  </table>

      </form>

</body>

</html>

However, it seems to ignore my rules I created and just proceed to the next page?

Any help please?

Thanks

Chris

Is this the code for the page process_submission.php or is process_submission.php a separate page?

Yeah, this I agree with aj_nsc, your post is confusing.

It looks like you might be trying to do client side validation with php.

There are two ways to validate forms. On the client side using javascript or the server side using php.

If you want to validate a form before submission use javascript. If you want to check a form after submission and then return to the form if there are erros, use php.

Hi,

It's using two pages in php. Basically here's the workflow:

1) User enters the details on that first page (ie page.php)
2) The page then checks the conditions
3) If they are true go to process_submission.php
4) If these are not true echo an $error

Thanks

Chris

Your form is not being submitted to page.php (it is being submitted to process_submission.php) and subsequently there will be no error handling. Hope this gave you an epiphany into how PHP works and why yours doesn't....if not, post back and we'll help you out some more.
