dynamic $_POST - help please

[mr_burns]

Hi there,

I am tryin to use a $_POST variable but the name of the form element
is dynamic. Below is the code I am tryin but is obviously wrong as it
isnt working:


$abc = $_POST['abc_' . $value]; //isnt working as is


If $value had a value of 44, the above code would be represented as:


$abc = $_POST['abc_44'];


As I require that the line be quite generic to whatever the value of
$value is, I need to do it like the first snippet. What is the correct
way of writting this? Cheers

Carved in mystic runes upon the very living rock, the last words of
mr_burns of comp.lang.php make plain:

There's no reason that shouldn't work, assuming there actually is a key in
$_POST with that value. Why not try dumping it and see?

That should work.

What isn't working? Dump your $_POST array and see if what you're
looking for is really there.
Show us the real code that isn't working. Or a URL of an example.

Why isn't it working?
What did you expect that to put into $abc?
What did that put into $abc?
How did you test?

Post some more code, please.

The reason that is not working /may be/ something else ...

Hi again,

Sorry, my mistake. I hadnt properly named the text box to link up with
the script. Thanks for the help anyway
