That is more a html thing than a django thing. Non-stone-age browsers will pass the particular submit button used for a form with multiple submits - and only that button - as only that button is "successful" (IIRC old IE used to do some wierd/dumb thing involving the name and/or value but I've largely suppressed the memory...) http://www.w3.org/TR/html401/interact/forms.html#h-17.13.2 (aside: You'll also still come across some ancient html tutorials claiming forms are allowed exactly one submit button, that is untrue) http://www.w3.org/TR/html401/interact/forms.html#submit-button i.e. given a POSTed form with two submit buttons <input type="submit" name="cancel" value="Cancel"/> <input type="submit" name="accept" value="Accept"/> Check request.POST.get('cancel') to see if cancel was clicked, and request.POST.get('accept') to see if accept was clicked. (remember someone curious can nonetheless construct a post request with both accept and cancel just to see if your server logic falls over in exploitable fashion) While django doesn't actually handle input type=submit for you, there are "SubmitField" snippets floating about. They may have advantages (e.g. form prefix handling, could in theory refuse to validate if more than one SubmitField of the form was successful from a malicious client, and maybe supply workarounds for that IE annoyance I only vaguely recollect), but may be overkill - you could e.g. just pass a "submit" dictionary down to the template, with a key and value to use as the name of various submit buttons (just to avoid hardcoding in the template) i.e. the above becomes (assuming you've stuck the submit dictionary on the form): <input type="submit" name="{{form.submit.cancel}}" value="Cancel"/> -- You received this message because you are subscribed to the Google Groups "Django users" group.
