Strange validation behaviour php

[codeblock]

Hello all,
I have a set of IF ELSE validation code ECHOING onto a php web page through a SWITCH staement. Everything works fine all error messages show up correctly. The problem is, after going through 3 conditons it starts to allow entry into my DB(mysql) all other entries goes straight through and stops validating.

if (empty($_POST[model]))
{                  		
  header("Location: " . $config_basedir . "/newcar.php?error=model"); 		     
}
if (empty($_POST[engine]))
{                  		
  header("Location: " . $config_basedir . "/newcar.php?error=engine"); 		     
}
if (empty($_POST[colour]))
{                  		
  header("Location: " . $config_basedir . "/newcar.php?error=colour"); 		     
}
else {
  header("Location: " . $config_basedir . "/newcar.php?error=date");
	       
	    }      
}
else { 
	require("header.php");     
              
?>  
       
<?php
	            
switch($_GET['error']) {
case "date":
         echo "<strong>Invalid date - please enter another!</strong>";
       break;
case "model":   
       echo "<strong>Please provide the vehicle model!</strong>";
      break;
case "engine":
     echo "<strong>Please provide engine type!</strong>";
      break;
case "colour":
     echo "<strong>Please provide colour of vehicle!</strong>";
      break;
		
    }	
			
	
}

?>

After each header("Location:") command you need exit, otherwise the script keeps running.

E.g.:

if (empty($_POST[model]))
{                  		
  header("Location: " . $config_basedir . "/newcar.php?error=model"); 		     
  exit;
}
if (empty($_POST[engine]))
{                  		
  header("Location: " . $config_basedir . "/newcar.php?error=engine"); 		     
  exit;
}
if (empty($_POST[colour]))
{                  		
  header("Location: " . $config_basedir . "/newcar.php?error=colour"); 		     
  exit;
}
else {
  header("Location: " . $config_basedir . "/newcar.php?error=date");
  exit;
// etc. ......

Adding the exit doesn't seem to work.

I can't post all of the code because it is too long. I will post a bit more.

This is as much as i can post besause the code it too long.
