How can I have one submit button for multiple forms?

Question

I have tried to make one submit button submit multiple forms using the following resources:

• https://www.daniweb.com/web-development/php/threads/255723/two-forms-one-submit-button-hw-does-it-work
• https://forums.digitalpoint.com/threads/post-multiple-forms-with-a-single-button-press-with-javascript.2271691/
• http://board.phpbuilder.com/showthread.php?10351103-submit-two-forms-with-one-button

When I use any of code from above, I can submit only one of my forms and its always the last one in the list of all form. I believe the problem could be that every form I have is in separate php file and I'm using include 'php/option-type.php' ; to include them in index.php where I also tested codes from above forum.

Answer 1

Combine both forms into one form, and then process the submitted data in a php script, which can then do both actions needed.

Can you give a little more information about the two forms, and what is each submit supposed to do? Then I'll be able to elaborate on my answer.
