help, with postcode splitting function / arrays...

[ja_blackburn]

Hi

 

I have a function that takes a postcode and splits it so i can enter into DB into two formats, full postcode and prefix.

 

The function is:

 

function check_form_postcode($postcode)

{

    $postcode = strtoupper(str_replace(chr(32),'',$postcode));

    $suffix = substr($postcode,-3,3);

    $prefix = substr($postcode,0,(strlen($postcode)-3));

    if (preg_match('/(^[A-Z]{1,2}[0-9]{1,2}|^[A-Z]{1,2}[0-9]{1}[A-Z]{1})$/',$prefix)

    && preg_match('/^[0-9]{1}[ABD-HJLNP-UW-Z]{2}$/',$suffix)) {

        $postcode_syntax_check = 1;

    } else {

        $postcode_syntax_check = 0;

    }

 

if($postcode_syntax_check){

$return = $prefix."::".$suffix;

}

 

return($return);

}

 

I POST the form data and in the top of the same page I get all of the form data and here is is where things go wrong:

 

if ($b == 'go') {

 

    //Gets form data

    $main_event_name = my_import('main_event_name', 'P', 'TXT');

    $main_event_type = my_import('main_event_type', 'P', 'TXT');

    $main_event_date = my_import('main_event_date', 'P', 'TXT');

    $main_event_city = my_import('main_event_city', 'P', 'TXT');

    $postcode = my_import('postcode', 'P', 'TXT');

    $main_event_added = my_import('main_event_added', 'P', 'INT');

    $main_event_active = my_import('main_event_active', 'P', 'INT');

 

    $postcode_array = check_form_postcode($postcode);

    $postcode = explode($postcode_array, "::");

    $prefix = $postcode[0];

    $fullpostcode = $postcode[0]." ".$postcode[1];

 

        $valkey = md5(microtime());

 

        $info = array(

 

              "main_event_name"=> $main_event_name,

              "main_event_type" => $main_event_type,

              "main_event_date" => $main_event_date,

              "main_event_city" => $main_event_city,

              "main_event_active" => $main_event_active,

              "main_event_added" => $sys['now'],

              "main_event_pcode" => $fullpostcode,

              "main_event_pcode_prefix" => $prefix,

              "eo_id" => $eo['id']

            );

        $table  = $db['main_event'];

 

        $userid = my_insert($info, $table);

 

When I enter into the DB all I get is the "::" no data. I know that the POST works as I can enter the data easily without the function going wrong.

 

Thanks for any help, i am new to arrays go easy if I have made an obvious mistake!

 

Cheers...

What does check_form_postcode() return?  Try calling it directly with known values, and then use var_dump on the result:

 

$return = check_form_postcode("ABCDE");
var_dump($return);
exit();

 

What should your code do if the postcode check fails?

 

Also check the manual page for explode(): http://php.net/manual/en/function.explode.php .  The arguments should be the other way around.

Thanks.

 

Are you saying that it should read like this:

 

$postcode = explode("::", $postcode_array);

 

I'm returning a 'NULL' btw

Actually I have it working now, thanks for the pointer.
