The appropriate way for doing this    app route      def index        if form validate on submit            if  download  in request form              pass   do something         elif  watch  in request form              pass   do something else   Put watch and download buttons into your template    lt input type  submit  name  download  value  Download  gt   lt input type  submit  name  watch  value  Watch  gt

Give your two buttons the same name and different values    lt input type  submit  name  submit button  value  Do Something  gt   lt input type  submit  name  submit button  value  Do Something Else  gt    Then in your Flask view function you can tell which button was used to submit the form   def contact        if request method     POST           if request form  submit button       Do Something               pass   do something         elif request form  submit button       Do Something Else               pass   do something else         else              pass   unknown     elif request method     GET           return render template  contact html   form form

In case anyone was still looking and came across this SO post like I did    lt input type  submit  name  open  value  Open  gt   lt input type  submit  name  close  value  Close  gt      def contact        if  open  in request form          pass     elif  close  in request form          pass     return render template  contact html     Simple  concise  and it works  Don t even need to instantiate a form object

I think this solution is good    app route   contact   methods   GET    POST    def contact        form   ContactForm       if form validate on submit            if form submit data              pass         elif form submit2 data              pass     return render template  contact html   form form    Form   class ContactForm FlaskForm        submit   SubmitField  Do this       submit2   SubmitField  Do that

I handle it in the following way   lt html gt       lt body gt            lt form method  quot post quot  action  quot   quot  gt                    lt input type  quot submit quot  value  quot Encrypt quot  name  quot Encrypt quot   gt                   lt input type  quot submit quot  value  quot Decrypt quot  name  quot Decrypt quot    gt            lt  form gt       lt  body gt   lt  html gt        Python Code       from flask import Flask  render template  request               app   Flask   name                   app route  quot   quot   methods   GET    POST        def index            print request method          if request method     POST               if request form get  Encrypt       Encrypt                     pass                 print  quot Encrypted quot               elif  request form get  Decrypt       Decrypt                     pass   do something else                 print  quot Decrypted quot               else                    pass   unknown                 return render template  quot index html quot           elif request method     GET                 return render template  quot index html quot               print  quot No Post Back Call quot           return render template  quot index html quot                 if   name         main             app run
