My Application Form not functioning correctly

Ruko · April 25, 2010

I followed a tutorial on making an contact form. I decided to turn it to a contact form with captcha but it gives me the following errors in the header.

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/ruko/public_html/JoinDevTeam.php:13) in /home/ruko/public_html/JoinDevTeam.php on line 49

Warning: Cannot modify header information - headers already sent by (output started at /home/ruko/public_html/JoinDevTeam.php:13) in /home/ruko/public_html/JoinDevTeam.php on line 81

Can someone fix this. I got the code at a tutorial.

 <?php
	{
   session_start();
   if(($_SESSION['security_code'] == $_POST['security_code']) && (!empty($_SESSION['security_code'])) ) {
      // Insert you code for processing the form here, e.g emailing the submission, entering it into a database. 
      unset($_SESSION['security_code']);
   } else {
      // Insert your code for showing an error message here
   }
if(isset($_POST['submit']))

  if(empty($errors))
  {
    //send the email
    $to = "[email protected]";
    $subject="Developer Queuing";
    $from = "[email protected]";
    $ip = isset($_SERVER['REMOTE_ADDR']) ? $_SERVER['REMOTE_ADDR'] : '';
    
    $body = "A user  $name wants to be a developer:\n".
    "Name: $name\n".
    "Email: $visitor_email \n".
"Username: $username \n".
"Why he/she wants to be a developer: $devwhy \n".
"Coding Knowledge: $codingknow \n".
    "Comments: \n ".
    "$user_message\n".
    "IP: $ip\n";  
    
    $headers = "From: $from \r\n";
    $headers .= "Reply-To: $visitor_email \r\n";
    
    mail($to, $subject, $body,$headers);
    
    header('Location: thank-you.html');
  }
}

A - That cannot be the whole code since session_start is not on line 49.

B - Find the sticky "HEADER ERRORS - READ HERE BEFORE POSTING THEM" On the forum this post is in.

The whole code is this:

The main problem is the form is not working like its supposed to.

Here is a summery of the sticky post that ChemicalBliss suggested that you read -

You cannot output any characters on a page before a header is sent as that prevents the headers from working. Session_start() and header() both send headers. Therefore, you cannot output anything before a session_start() statement or a header() statement.

You must rearrange the code on your page so that any session_start() or header() statements come before any content on your page. Content on your page is any of the following - the HTML DOCTYPE tag, css, javascript, and html.
