Django request.POST does not contain the name of the button that submitted the form

I have a django form with two different submit 开发者_开发技巧buttons, on the view where the form is submitted to I need to know what submit button was pressed and take different actions accordingly.

From what I have read the submit button's name or id should be somewhere in the request.POST dictionary, but it not there!

This is a fragment of my form:

<form id="editPaperForm" action="{{paper.editURL}}" method="POST">
   <input type="submit" name="savePaperButton" id="savePaperButton" value="Save and Send Later"/>
   <input type="submit" name="sendPaperButton" id="sendPaperButton" value="Save and send"/>

   ...

</form>

In the view:

...
if 'sendPaperButton' in request.POST:
   return applicants_confirmSend(request, paperID)
else:
   return applicants_home(request)

sendPaperButton is never in the request.POST, and neither is the other one, should I be looking somewhere else?

The only idea I have is to add a hidden field and modify it via javascript before sending the form but that seems kind of redundant since I'm pretty sure that data should be there somewhere...

Thanks!

Don't forget to add the name and value parameters to your "button" or "input type=submit" fields of the form. I've had the same problem once and it drove me crazy.

In short, as request.POST contains a dict, you need a key and a value. The key corresponds to the name parameter of your button, and the dict's value to the button's value.

<button type="submit" value="preview">Preview</button>

won't be reflected in request.POST (there's no key for the POST dictionary!), whereas

<button type="submit" value="preview" name="preview">Preview</button> 

will have a key "preview" with value "preview".

For some reason, in Chrome, when I had two buttons using <input/> tags, it would actually treat the button I didn't click as an input. That way, when I tested something like 'sendPaperButton' in request.POST, it would return the opposite of what I wanted.

I changed these to <button></button> tags and it worked fine.
