do string operation on entered value

  1. Hi, I would much appreciate a pointer to help me figure something out: I want to add a "filter" (or is it a "hook?" - not sure) to change any entries containing "https" to "http" for a specific form field. How do I go about this? I know I need to add something to functions.php, and probably use a hook or a filter, but I'm not sure how to proceed.

    Your advice will be much appreciated.

    Marc

    You'll probably want to use

    As for changing the https to http you'll want to use PHP for that.

  3. David, thanks a bunch!

    Is there a "hooks and filters for beginners" page someplace?

    Not currently, no. There is only the documentation section with all the hooks and filters listed within including examples.
