Array help

[EchoFool]

I am having difficulty understanding arrays. I read through page about them but didn't explain how to get it working via a form with checkboxes and inputboxes to set the array...

 

 

<input type="text" size="16" name="Quantity[<?=$Array?>]" value="">
<input type="checkbox" name="Checkbox[<?=$Array?>]" value="<?=$ItemID?>

 

I have this in a while loop that loads a list of items, and what it does is, it puts the itemID in the checkbox...so the selected checkboxes will have a list of ItemID's.

 

Then with that it is meant to grab the quantity from the Quantity input box adjacent to it.. so the array would end up forming like this:

 

Id     |   Quantity
2     |       34
5     |       2
6     |       23

 

I think i got it right with the above two lines but I don't know how to call it up on a processing page to use the data from the array

Only checked checkbox values are posted, so

 

<?php
foreach ($_POST['Checkbox'] as $k = $id)
{
      $qty = $_POST['Quantity'][$k];                // get corresponding qty 

          // process $id and $qty

}

So do i even need to have the names :

 

Checkbox[<?=$Array?>]
Quantity[<?=$Array?>] 

 

For the 2 input boxes still then ?

Only checked c/boxes are posted but you need to make sure that textbox[N] belongs with checkbox[N] so

<?php
$count=0;
while (.....) {
  <input type="text" size="16" name="Quantity[<?=$count?>]" value="">
  <input type="checkbox" name="Checkbox[<?=$count?>]" value="<?=$ItemID?>
   $count++;
}

Oh i see so the $Count for both of them would then equal the same value which is how they are linked? I think i understand now Thanks Barand.
