A silly $_POST question
Can you include variables in the brackets?

 7:07 pm on Nov 9, 2005 (gmt 0)

What I am trying to do is dynamically load a form for updating a text file. In dynamically building my form, I have line number and field number to name the fields. ie.

echo "<input type='text' name='$linecount_$filedcount' value='whatever'>";

When I send this to the next page ... I would like to write to the file like this:

$tempvar = $linecount . "_" . $fieldcount";

Of course I don't even know if a variable in the $_POST array is even possible. Is it?

It's fine -- $_POST is just a (superglobal) array.

you could also just run through the $_POST array with a foreach as well, getting the keys at that point, allowing less margin for error. Making sure you build the exact same thing twice can sometimes get a little out of control.

Also before you just start writing vars into files I would clean them first. The general scenario is a perfect one for XSS.
