I am a PHP retard!

[murray price]

Hi,

 

I am trying to put together a script that allows visitors to my site to enter a postcode in a search box and then if the postcode matches one that is on a list the visitor is sent to a success page if not a fail page. This is the script I have so far:

 

<?php

 

$postcode_area = "kt18";

 

if(isset ($_POST["postcode_area"])){

if($_POST["postcode_area"] == $postcode_area){

 

    header("Location: ../area-covered.htm");

exit();

}

 

else{

  header("Location: ../area-not-covered.htm");

exit(); 

}

}

?>

 

This works fine if the user enters the one postcode shown 'KT18' but I have about 100 I want to include for the script.

 

Can anybody help me we out with this? I kinda know that I need to do a for each loop and explode it but I am just not advanced enough yet to pull this one off! Thanks for any help

1. Use code tags.

2. What format is the list of 100 post codes now?

3. in_array

It is just list like:

 

kt18

sm3

sw11

 

etc

 

The person will only be entering the first block of their postcode and their are about a 100 of these. Thanks

So it's in a text file?

 

Put it in an array, and use in_array.

Or import it into a database.

I've got no idea how to do that

<?php

$valid = array('kt18','sm3','sw11','etc');

$lowercase_postal = strtolower($_POST['postal_code']);

if( in_array($lowercase_postal, $valid) ) {
echo 'Found';
} else {
echo 'Not found';
}

?>

Hi, Thanks.

 

I have changed the echo's to header to redirect to a new page but when I add any search now it just directs to the fail page.

 

<?php

 

$valid = array('kt18','sm3','sw11','etc');

 

$lowercase_postal = strtolower($_POST['postal_code']);

 

if( in_array($lowercase_postal, $valid) ) {

header("Location: ../area-covered.htm");

exit();

 

} else {

header("Location: ../area-not-covered.htm");

exit();

}

 

?>

You searched for one of those three that you added?

 

In your original code you called the input "postcode_area" now you have "postal_code"

Its ALIVE! Thanks for all your help...

 

<?php

 

$valid = array('kt18','sm3','sw11','etc');

 

$lowercase_postal = strtolower($_POST['postcode_area']);

 

if( in_array($lowercase_postal, $valid) ) {

header("Location: ../area-covered.htm");

exit();

} else {

header("Location: ../area-not-covered.htm");

exit();
