if I have the following html:
<form method ='GET' action='/search'>
<input type='checkbox' name='box1' id='box1'> Option 1
<input type='checkbox' name='box2' id='box2'> Option 2
<input type='submit'>
</form>
How could I know whether one of the checkbox was selected (TRUE/FALSE) in python/django? I am writing an app in Django and I would like to show a specific result depending on which checkboxes were selected.
Many thanks in advance!
If it exists in request.GET, it was checked, if it is not, it was not checked.
see this question: Does <input type="checkbox" /> only post data if it's checked?
Edit: example check:
if 'box1' in request.GET:
# checked!
...
else
# not checked (or the form was never submitted.)!
...
def checkbox(request): filter = "" flavour =["dark", "white", "nougat"] for f in flavour: if f in request.GET: filter += f return HttpResponse(render_to_string('page.html',{'filter':filter}))<form action ='/checkbox' method='GET'> <input type="checkbox" id="dark" value="dark"> <input type="checkbox" id="white" value="white"> <input type="checkbox" id="nougat" value="nougat"> </form>A couple of ways to accomplish this.
if not request.GET.get('checkboxName', None) == None:
# Checkbox was selected
selectedFunction()
else:
notSelectedFunction()
# Another Way
if 'checkbox' in request.GET:
# Checkbox was selected
function()
else:
notSelectedFunction()
Now if you are trying to get data from a posted form just change it from GET.get to POST.get - I would advise if you are trying to 'remember' what was selected to store it in a session or in a cookie. Sessions will be a lot easier to setup and will work just the same as cookies. However, if this is for a 'remember me' a cookie would be the best choice to remember the data.
