Hi all,

Ok it's 2am, my brain has gone to mush and I am having trouble
figuring out an easy way to do this, can anyone shed some light?

Take a peek at the following code:

    $userparam = "test['sam'][]";

    //  How to check if $userparam exists in the $_POST array
    //  and get all the values from it?
    //  Obviously this won't work, but you get the idea:
    if (isset($_POST[$userparam]))
        echo 'yeah';
        $values = $_POST[$userparam];
        echo 'nah';

<form method="post">

<input type="checkbox" name="test['bob'][]" value="red">red<br>
<input type="checkbox" name="test['bob'][]" value="green">green<br>
<input type="checkbox" name="test['bob'][]" value="blue">blue<br>
<input type="checkbox" name="test['sam'][]" value="red2">red2<br>
<input type="checkbox" name="test['sam'][]" value="green2">green2<br>
<input type="checkbox" name="test['sam'][]" value="blue2">blue2<br>

<input type="submit">

// END

From the code above I'm trying to figure out how to tell if the
$userparam exists in the $_POST array. PHP automatically expands the
form element name into multi-dim arrays within $_POST, so a simple
'isset' as shown in the code above won't play because it's got a
totally useless array key passed to it.

I need a way to turn the string:


into something I can look into $_POST for.

Any ideas? The coffee boost is wearing off, but I want to get this
licked tonight :-\
