Change this line:if (getpostcode($_GET['postcode'])!=''){to this:if (!empty($_GET['postcode']) && getpostcode($_GET['postcode'])!=''){

Hi, The error has gone, but gives the result that the zip code (postcode) is wrong= error resultI know for sure that the zipcode is 100% correct , declined at line 2Simon

It's not checking the postcode declared on line 2, it's checking for a postcode in $_GET. e.g.:page.php?postcode=abc123

It's not checking the postcode declared on line 2, it's checking for a postcode in $_GET. e.g.:page.php?postcode=abc123

I understand that the code checks $_GET. e.g.:Does it means that my variable at line 2 is not valid or emptyExact as you told the page should be page.php?postcode=abc123 (1628DC)But how manege i to change the script that it receives the correct zip code.Best regardsSimonHoorn, Netherlands

Have line 2 get the postcode.$postcode = !empty($_GET['postcode']) ? $_GET['postcode'] : '';Then change the if statement on the bottom to use that instead:

if (getpostcode($postcode)!=''){echo "The accordinates are: ".getpostcode($postcode);}

Since you're using CURL to send that request out, it will probably be better to run the getpostcode function once and save the return value to a variable, and then use that in the if statement instead. That way you don't have to send 2 requests out.
