more than one form on a page

[ms1990kl]

As I have prefaced every one of my bonehead posts on this forum, I am relatively new to PHP, so I am sure that the following is pretty rudimentary, but it is very hard to find answers sometimes in the PHP books.  This forum has been great!

 

I have a website that has 2 forms on one page.  One form inputs a bunch of data and makes some calculations which are displayed.

A second form allows you to choose a few of these displayed calculations and do some more calculations with those numbers.

 

The problem is that when I click the submit button on the second form, the first form does a whole new set of calculations.  It doesn't hurt the results, but it looks sloppy.

 

Both forms use if(array_key_exists).  I think that after the first form is submitted, its array_key still exists, so that when the second form submit button is hit, the first form is processed.

 

Is there some way to kill or erase an array_key after a form is processed.

 

Or is there another way to do what I am trying to do.
