using $ POST with an array element

$_POST['ingred[1]']

[someone]

$_POST['class[1]'] doesn't seem to work.

This works:

<input name="class[1]" type="text" value="<?PHP if(isset($class[1])) echo $class[1];?>">

This doesn't work:

<input name="class[1]" type="text" value="<?PHP if(isset($_POST["class[1]"])) echo $_POST["class[1]"];?>">

When you define an array structure in the name attribute of an input, PHP automagically arranges the $_POST superglobal as an array.

This code:

<input type="text" name="test[fish][1]" value="2" />
<input type="text" name="test[fish][red]" value="blue" />

Ends up being accessible through:

echo $_POST['test']['fish']['1']; // 2
echo $_POST['test']['fish']['red']; // blue

To see the structure for yourself, just do a

print_r($_POST)

:)

That works perfect! Thanks, Whoisgregg!
