I have some code that creates the name="" of an input from mySQL data. I then want to pass this input name into a $_POST. The problem I have is that I don't know what the actual variable will be. I'd like to pass a variable into the post command like this:

$_POST[$forminputname]

but this is not working. Does anyone have any ideas on this? Thanks.

Couldn't you create a variable and set it equal to what you pull from the SQL

$forminputname = results of your SQL data;

and then pass $forminputname as you show in your post.
