I have a form with two submit buttons. Rather than call two different methods as in <form action="" method="post"> ... <input type="submit" name="some_func:method" value="Button 1"> <input type="submit" name="some_other_func:method" value="Button 2"> </form> I would like each button to call the same function, but with a different value for a variable. Something like: <form action="" method="post"> ... <input type="hidden" name="somevar" value="someval"> <input type="submit" name="some_func:method" value="Button 1"> <input type="hidden" name="somevar" value="someotherval"> <input type="submit" name="some_func:method" value="Button 2"> </form> But this doesn't work. Any suggestions? Thanks, John Hunter

I do this with JavaScript. Use a hidden input tag to store the variable, and call a function (with your parameters) on the click event of your button which sets the parameters in the request and submits the form. It's not the greatest solution, but it works. I need to use JavaScript anyway since my buttons aren't in the same frame as the form. Harry

the submit buttons count as form-fields as well , so you don't need the hidden form-fields at all : <form action="some_func" method="post"> <input type="submit" name="somevar" value="someval" /> <input type="submit" name="somevar" value="someotherval" /> </form> -- Geir Bækholt web-developer geirh@funcom.com funcom oslo | webdev-team

Ah, good point :) I am just using the hidden form fields because I have my buttons in a different frame (and thus in a different form). Looks like John's problem is easier to solve than I though :) Harry

Could this be used instead? <input name="yourEditMethod:method" type="submit" value="Update Form" /> <input name="yourAddMethod:method" type="submit" value="Add Event" /> cheers, Chris

I've done something similar (?) in the past: <input name="foo" type="submit" value="Foo Text" /> <input name="bar" type="submit" value="bar Text" /> ... and then in the (single) script handling form submissions, I just tested for existence of foo and bar. I forget exactly the code I used to do that, but it was pretty easy. In your version, where are yourEditMethod and yourAddMethod defined? Are they acquired from somewhere? I smell a better solution than mine, but I don't quite follow how this works... -- "Welcome to Muppet Labs, where the future is made - today!"

This is ZPublisher being useful and it's actually documented in the dead tree version of the Zope book. If the action of the form is an object, say: <form action="http://server.com/an_object"> Then the stuff I posted will result in the following method call: an_object.yourEditMethod(REQUEST) ...of course, the parameters are adjusted by ZPublisher too to match that of your method :-) hope this makes sense, Chris
on or about, Thursday, May 09, 2002, we have reason to believe that John Hunter wrote something along the lines of : [snip] JH> But I realize that I can process these in the add function, with JH> if somevar=='Update Form': JH> somevar=0 JH> elif somevar=='Add Event': JH> somevar=1 JH> else: JH> raise 'Did you change the value of your add form buttons and forget to change your add function again?'

In this case , neither of the values from the submitbuttins are sent, and your application will raise 'Did you change ..... you might want to let the else:clause point to one of your options , if one can be considered a default.. :-) -- Geir Bækholt web-developer geirh@funcom.com funcom oslo | webdev-team
Please don't do that. It's a maintenance nightmare, an internationalization nightmare, and an ugly design to boot. Use the :method idiom, it's designed to that. Florent John Hunter <jdhunter@ace.bsd.uchicago.edu> wrote:

Right, but unless I'm missing something, the method idiom is used to call different methods. If you saw the original post, I want to call the same method with different values for a given variable. Can you do this with :method? Thanks, John Hunter
Ok there are basically two ways. The one I use in most cases: <form action="some_func"> ... <input type="submit" name="submit1" value="Button 1"> <input type="submit" name="submit2" value="Button 2"> </form> and check which of "submit1" or "submit2" variables exist to distinguish the buttons. Or use :method with two different methods: some_func.py ##parameters=..., isbutton2=0 ... processing here ... some_other_func.py: ##parameters=... context.some_func(..., isbutton2=1) Florent John Hunter <jdhunter@ace.bsd.uchicago.edu> wrote:
