Arrays in URL?

bdata28

Is it possible to send an array to the URL and then extract it? I have created an array of error messages for a form. When the form is submitted the data is verified and may have more then one error message that I've put into an array. If there are errors then the following occurs:

header("Location: $login_page?error=$gError");

It shows up as login.php?error=Array in the URL. When I try to loop through the array it ends up:

$error[0] = "A"
$error[1] = "r"
$error[2] = "r'

Is this not possible or do I need to rethink my stradegy?

Thanks

you could use implode and explode to turn your array into a string and back...

<?
$error[0] = 31;
$error[1] = 25;
$error[2] = 17;

$error = implode("-", $error);

echo $error;

$error = explode("-", $error);

echo serialize($error);
?>

i use arrays all the time passing them arround, even key valued arrays

this is what you have to do

just loop and build your string and use the open array notation

$uri_string = 'index.php?';
foreach($err_array as $err_code)
{
    $uri_string .= "array_name[]=" . $err_code . "&";
}

this will give you a single dimension array

if you want a key value array

foreach($err_array as $err_code => $err_str)
{
    $uri_string .= "array_name[" . $err_code . "]=" . $err_str . "&";
}

just a note that theres a limit of how much data you can pass when dealing with get method, i think its up to 1024 bytes

dont forget to urlencode or htmlentities your values

...or use serialize() to do it more reliably. Either way, use urlencode() as well so URL-unfriendly characters don't slip in.
