My question is over creating a self-processing form that inserts to a database and then refreshes, incrementing arrays to change relevant info in the form. (though if there is an easier or better way to do this, I'm all ears).
So site is essentially a digital equivalent to an exercise journal. The user selects a template name from a select menu, then it queries the database for that template, then returns the result to a variable. The exercise names and number of sets per exercise (which will be used to calculate maximum number of form refreshes) are passed into their own respective arrays: $exerciseName[]; and $setNum[];
This is a screenshot of the form. My question is how to go about setting up the logic so that I can keep submitting until the last set of the last exercise, where upon the final submission, would take to a different page.
I am using mysql_ functions, which I know is frowned upon, but it is for school which uses PHP 5.2.12 and that is what my teammates know so I have no other options. I haven't tried to prevent mysql injections because I don't intend to take this version online.
Here is the code for selecting type of workout and workout template:

//Default page buttons
$cardioBtn = $_POST['cardioBtn'];
$resistanceBtn = $_POST['resistBtn'];
//Cardio submit
$cardioSubmit = $_POST['cardioSubmit'];
if ((empty($cardioBtn))
