Passing arrays from HTML form to PHP

Question

This is the HTML:

 do 

<         


        

Answer 1

The indexes are connected automatically, since they're numeric arrays.

$nvals = count($_REQUEST['shortcut']);
for ($i = 0; $i < $nvals; $i++) {
  // do something with $_REQUEST['shortcut'][$i] and $_REQUEST['ses'][$i]
}

Answer 2

You can specify shortcut value as the key and the ses value as the value attribute:

<input type="text" name="input[a]" value="1" />
<input type="text" name="input[b]" value="2" />
<input type="text" name="input[c]" value="3" />

On the server-side you could use a foreach loop to iterate over the array:

foreach ($_POST['input'] as $shortcut => $ses) {
    // process $shortcut and $ses
}

Answer 3

Combined array: array_map(null,$_POST['shortcut'],$_POST['ses']);

But you could of course could foreach over one of the 2, and fetch the other by key.

Note that if you have elements which may or may not be sent (checkboxes for instance), the only way to keep groups together is to assign them a number beforehand (name=sess[1], name=sess[2], etc.)
