PHP Postcode Search - HTML Forums

tom_haire50 · 11-05-2009, 11:34 AM

I have created a website with a postcode search, all the postcodes are stored in a text file. The php searches through text file to see if a postcode typed in by the user is in the text file.

I have set it up so that it only reads the first part of the postcode e.g. YO12 4AA is typed in the php with search the text file for YO12, it reads up to the space.

If someone types in YO124AA (without a space) it searches the whole postcode, which is not contained in the file. My code is below i cant think of a better solution without using a database

PHP Code:


			
<?php 

$handle = file_get_contents("Postcodes.txt",NULL); 

$submit=$_POST['Submit'];

$a =$_POST['Postcode'];

$a=str_replace(",","",$a); 

$a=explode(" ",$a);

$postcode = reset(explode(' ', $postcode));

$c=0; 

foreach($a as $y){ 

if (stristr($handle,"$a[$c]")) $b[]= 'yes'; 

else $b[]='no'; 

$c++; 

}



if (in_array("yes",$b)) header("Refresh: 0; url=inYourArea.html?i=idx");

                        



else header("Refresh: 0; url=notInYourArea.html?i=idx");



?>

UK postcodes?

hmm.. you could try this:

PHP Code:


			
$area = explode(' ', $_POST['postcode']);

if (strlen($area) > 4) { // since, I believe, the area code is never more than 4 characters

  $area = substr($area, -3); // since the street part of the postcode is always 3 characters

}

// search using $area

Yeah, I never thought of that! In theory it should work alright. I will change it over now and see how it goes.
