Pass Arrays in forms

[JohnnyB]

I am trying to pass an multiply values from many text fields that have the same name, qty.

I read to do this I should have my form set out as such:
<input type=text name=qty[] value=$values[$i]

My code goes through a loop inserting values in the qty text field. I then use GET to send it to the next page. I was then told to use:
$quantity = serialize($_GET['qty']);
to get the data. I have to use serialize otherwise if I echo the result without serialilze i get 'Array' outputted. Using serialize i get:
a:2:{i:0;s:1:"1";i:1;s:1:"1";}

the url read:
?qty%5B%5D=1&qty%5B%5D=1

I was told that If i then used unserialize that I would get the results I wanted, but:
$quantity = unserialize($quantity);
echo $quantity;

gives me no output what so ever. Can anyone please tell me what im doing wrong? Or a better way to get the results I want?

Thanks.

Hi JohnnyB

Why are you using GET as your FORM method?

If you use POST as your method, you don't need to serialize or unserialize anything -- you simply receive the values and use them.

For example, if you have:

for($i=0;$i<5;++$i) {
print '
<input type="text" name="numbers[]" value="'.$i.'">
';
}

Now, if you receive this in your next page as $_POST["numbers"], you'll be left with an array in that variable. Then, you can use the foreach() to access each element of that array.

Hope this helps.

kevinc,
I was using GET so I could see what values were being passed. I made the change to POST and it now works. Thank you for your help.
