Redirect based on postcode/zip code

[pock0]

Hi, can anyone help me?

 

I am trying to create a form which asks the user to input their postcode then submit. the purpose is so if the service my site offers is not available in the location that the end user lives, then I want to display a message saying 'Sorry, not available', but if they are in area then it redirects to another page.

 

My form code is:

<form method="post" action="forwarder.php">
    <p> Enter Post Code Here:<input type = "text" name = "zip" id = "zip" size = "10" maxlength = "5" ">
	<input type='submit'>
    </form>

My PHP is:

<?php
$zip = isset ($_POST['zip'])  { 
  if ($zip=='NG15') { 
    header('Location: https://www.bing.com');
} else { 
  	header('Location: http://www.google.co.uk')
}



?>

I am a bit of a newbie at this, and I know my PHP won't give me my desired result, but I was using this to try and test the concept. Help would be really appreciated, and if you can show me how to do it for multiple postcodes even better

isset() return true or false, not the value of of the variable being tested.

if (isset($_POST['zip']) && $_POST['zip'] != '') {
   if ($_POST['zip'] == 'NG15' {
        header('Location: https://www.bing.com');
   } else { 
        header('Location: http://www.google.co.uk')
   }
}
else {
    header("Location: postcodeform.html");
}

For multiple postcodes you have several choices

• array
• text file
• database

If you use an array, the test would be like this

$codes = array(
        'NG15',
        'NG12',
        'NG1'
    );
    
if (in_array($_POST['zip'], $codes))

If you use the other two then you could read from the db or text file and put the codes into an array then the processing from then on would be the same

Im not getting much luck. When I hit submit I just get a blank page, any ideas?

[Barand]

Do you have any error reporting turned on?

 

If not, put this at top of your page

ini_set ("display_errors", "1");
error_reporting(E_ALL);
