Post Array 3

[ZOR]

Is it permitted to make a form posted variable an array?

eg.
$_POST['SOMETHING'][1]
$_POST['SOMETHING'][2]
etc,etc.

instead of:
$_POST['SOMETHING1']
$_POST['SOMETHING2']

Thanks

Sure. It's even documented in the online manual:

This comes into play when you have more than one field with the same name on your form:

<form>
    <input name="test" [...] />
    <input name="test" [...] />
    <input name="test" [...] />
</form>

You would then access these as:

$_POST["test"][0]
$_POST["test"][1]
$_POST["test"][2]

More often, though, you will encounter this when trying to parse multi-selects:

<form>
    <select multiple="true" name="test[]">
        <option value="1" selected="true">One</option>
        <option value="2" selected="true">Two</option>
        <option value="3" selected="true">Three</option>
    </select>
</form>

And you would then access these as:

$_POST["test"][0]
$_POST["test"][1]
$_POST["test"][2]

Take Care,
