problem passing variable between forms.

[Angelo Zanetti]

HI all

I have a form in which I have a table with dynamic checkboxes, they are in a
checkbox array ( name = chk[]...), I pass this variable to the next page
using POST I receive the variable and use it, no problem, but then when I
try to pass it to the next form in the URL (using an A HREF:

<a href='confirmrequest.php?requested=" . $chk . "'> )

then it doesnt get passed. I have also tried sending it with POST and a
submit button


On the page that receives the variable (or meant to ) I have tried this with
POST:

$chk_array = $_POST['chk'];


================================================== =====
and this with sending the variable as part of the URL:

echo("count chk: " . count($requested). "<br>");
================================================== =====

My register_globals is off. I am not sure what Im doing wrong,

Help would be appreciated

Thanx In advance

Angelo

You need to serialize() the array in order to pass all of it's values.

$ser = urlencode(serialize($chk));

$url = "confirmrequest.php?requested=$ser";

Then on the receiving side...

$chk = unserialize($_GET['requested']);

You could also just add it to the session and make it easy...

$_SESSION['chk'] = $chk;

and on the receiving page:

$chk = $_SESSION['chk'];

Isn't $chk an array? To pass an array in a form, you should serialize it and
encode it, then after receiving it you decode it and unserialize it:

$portable_array = base64_encode(serialize($array));

You can then pass $portable_array as a form hidden input value. To turn it
back into an array:

$array = unserialize(base64_decode($portable_array));

Read back through your question, and at least one problem should be very clear:

1. The client sends you data in a POST request.
2. You have register_globals disabled.
3. You reference $chk.

You need to reference this as $_POST['chk']. Read this:

[url]http://www.php.net/register_globals[/url]

Also, as others have mentioned, you need to understand how to work with arrays
a bit more. The manual can be very helpful. Read this:

Hope that helps.

Lowell, thanks so much for this response. I am trying to send information from a database query to a form that a user can email and this worked great!
