I'm basically having the same issue addressed in a previous question (Django request.POST does not contain the name of the button that submitted the form) but the fix described there does not work.
I am using ajax so that, after submission, I stay on the same page. My page has two forms. The first form has three buttons and I correctly pass the "name" of the button in the GET request. My second form has two buttons but I am unable to pass the "name" of either button in the GET request (the "name" of the input field, however, is in the GET request). I don't know why it's not working. Any ideas?
JS SOLUTION:
$(document).ready(function(){
console.log("hello from email.js");
$('.email_citations').submit(function(event){
console.log("submit email");
var whichButton = $(".form_button[clicked=true]")[0].value
console.log("WHICH BUTTON: ");
console.log(whichButton);
var email_address = $(this).val();
var data = $(this).serialize();
data += "&" + whichButton;
console.log(data);
$.ajax({
data: data,
type: $(this).attr('method'),
url: $(this).attr('action'),
success: function(data){
console.log("DATA: ");
console.log(data);
$('.email_sent_message').html(JSON.parse(data).submit_message);
}
});
return false;
});
$(".form_button").click(function() {
$(".form_button").removeAttr("clicked");
$(this).attr("clicked", "true");
});
});
html forms:
<!-- This form works! -->
<form action="export_options" method="get">
<button type="submit" name="plain" class="button inline large hover" id="exportButton2">Download Plain Text</button>
<button type="submit" name="ris" class="button inline large hover" id="exportButton1">Download RIS File</button>
<button type="submit" name="bibtex" class="button inline large hover" id="exportButton3">Download BibTeX File</button>
</form>
<form class="email_citations" id="EmailCitationsForm" action="email_it" method="get">
<input class="input-text" type="text" size="75" maxlength="75" style="width: 40%; font-size: 16px; margin-right: 5px; height: 50px" name="email_address" placeholder="email address">
<button type="submit" value="selected" name="which_citations" class="form_button button inline large hover" id="exportButton4" >Send My Selected Citations</button>
<button type="submit" value="all" name="which_citations" class="form_button button inline large hover" id="exportButton5">Send All Citations</button>
</form>
<div class="email_sent_message" style="float: left; color: #9e1d2a; font-size: 20px; font-weight: bold">{{ submit_message }}</div>
My javascript/ajax in an email.js file:
$(document).ready(function(){
console.log("hello from email.js");
$('.email_citations').submit(function(event){
console.log("submit email");
var clicked_button = $(".form_button[clicked=true]")[0].name;
console.log(clicked_button);
clicked_button.push($(".form_button[clicked=true]")[0].value);
console.log(clicked_button);
var email_address = $(this).val();
var data = $(this).serialize();
data += "&" + clicked_button;
console.log(data);
$.ajax({
data: $(this).serialize(),
type: $(this).attr('method'),
url: $(this).attr('action'),
success: function(data){
$('.email_sent_message').html(JSON.parse(data).submit_message);
}
});
return false;
});
$(".form_button").click(function() {
$(".form_button").removeAttr("clicked");
$(this).attr("clicked", "true");
});
});`
My view:
def email_it(request):
context = RequestContext(request)
if request.method == 'GET':
getdict = request.GET.dict()
form = EmailCitationsForm(request.GET)
if form.is_valid():
context = request.session.get('All_Citations_Context')
if ('which_citations') in getdict.keys():
if 'all' in getdict.values():
text_template = 'email_allCitations.txt'
html_template = 'email_allCitations.html'
text_content = render_to_string(text_template, context, context_instance=RequestContext(request))
html_content = render_to_string(html_template, context, context_instance=RequestContext(request))
msg = EmailMultiAlternatives(subject, text_content, from_email, to)
#msg.attach()
msg.attach_alternative(html_content, "text/html")
msg.send()
submit_message = "Thank you. Your citations have been sent via email."
return http.HttpResponse(json.dumps({'submit_message': submit_message}))
if 'selected' in getdict.values():
text_template = 'email_selectedCitations.txt'
html_template = 'email_selectedCitations.html'
text_content = render_to_string(text_template, context, context_instance=RequestContext(request))
html_content = render_to_string(html_template, context, context_instance=RequestContext(request))
msg = EmailMultiAlternatives(subject, text_content, from_email, to)
msg.attach_alternative(html_content, "text/html")
msg.send()
submit_message = "Your citations have been sent via email."
return http.HttpResponse(json.dumps({'submit_message': submit_message}))
else:
submit_message = "Something went wrong. Sorry, your email did not send."
else:
submit_message = form.errors['email_address']
else:
form = EmailCitationsForm()
submit_message = ""
return http.HttpResponse(json.dumps({'submit_message': submit_message}))
