I have learned how to display variables in template toolkit with <% varname %>. However, these variables are being named from withing my dancer app and displayed on the template. Is there a way to display variables that a user is entering as they are entering it. So that if I have a menu like form where a user can pick several items and see them each added one by one in a list format before pressing a second submit button that submits his entire lists of entries? It would be a bit like a shopping cart but instead of the items being put in the cart they are displayed right there in the form as they are added. Thanks for any ideas. Richard

Not as part of TT - that all happens server side.

In which case you have 2 options: 1. Process it client-side with javascript (not recommended) 2. Make each "addition" a new request, and store server-side You could also do a combination with AJAX-type calls, which is probably the best "modern" way of doing it, although it will be more complicated than option 2.

Hi Andy, So if I have the users choices (that I want to re-display as a list) coming back in the POST. Once I have turned them into a session variable what is the best way to re-request the page? Should I just do a redirect or would some other method be better? post '/featadd' => sub { # let user enter info my $input_hash = { game_id => param('game_id'), spsrd_chlg_id => param('spsrd_chlg_id'), period => param('period'), }; session list_hash => $input_hash; }; #re-request the page and display list_hash ??

I have gone the with option 2. Basically I have two forms in the template. Form 1 lets the user add an item. Form 2 keeps a running tally of the items thus far added. What I can't figure out is how to make dancer differentiate between the two forms so that it knows that the user is done adding items and wants to check out so to speak he can hit the submit button of Form 2 to save all his submissions. Both forms have submit buttons but I am not sure how to make the POST route understand that the user is done with the form so that I can in turn make it save the data. Thanks for any ideas.

Umm... each form has it's own POST target? Or instead of two forms, you keep the running totals in DB with the keybeing the sessionID for that session. When they click on the main "submit" button, it just does a call to the page which totals it all up and presents things for final submission. So you'd just one form, which is for entering things. And then a seperate javascript button which calls in to do the final wrap up. Does this make sense? Sorry I don't have example code... John

Hi John, Yes that make sense but I guess what I am not clear on is how do I distinguish between the two submissions so that the post route knows that the user is done and to take further action? You mentioned as JavaScript button but how does such a button let the POST route know that the user is done? Sorry if I am not following something that should be obvious.

You can differentiate between submit buttons by checking for the name of the submitted button, just like any other control on the form. If I've understood correctly, then I'd just have the one form, and use different submit button names. Andy

So provided that I have named one button with name="add_entries" and the second name="submit_entries" could i just do the following in my dancer app: post '/entries_form' => sub { if (defined param('add_entries')) { # the source of this submission was the add_entries button # qualify and summarize addition } elsif (defined param('submit_entries')) { }

Sent before I was finished. Gmail needs to take the send button out of the tab index!!! So provided that I have named one button with name="add_entries" and the second name="submit_entries" could i just do the following in my dancer app? post '/entries_form' => sub { if (defined param('add_entries')) { # the source of this submission was the add_entries button # qualify and summarize addition redirect '/entries_form'; } elsif (defined param('submit_entries')) { # update submission to make them final }

Yes, exactly that. As an aside, you can lose "defined" (might make the code a little more readable), as long as you have a value for the submit button. Andy

Hi Andy, The only thing with the approach of two submit buttons is that the second submit button triggers the required fields that are meant for the first submit button and thus don't allow the submission. Would you happen to know a way around this? Thanks
I use an onClick function (an event handler would probably be better) for buttons rather than the default behavior. In my case I use it to pre-process the data so it is more easily managed by Dancer2. On 10/6/2015 8:46 AM, Richard Reina wrote:

I ended up separating it into two different forms -- one for each submit button. Thanks for the onclick idea though.

Surely that doesn't matter and you can just ignore those fields? if (param 'submit1') { my $value1 = param 'value1'; } elsif (param 'submit2') { ... # process second submission }

Andy, Thanks for the help. I think just for my one quirky reasons I am going to use two forms in the template. Hope that an okay way to do it. Let me know if you think it could be problematic. Thanks again.

TBH, that makes sense, if it is 2 separate sets of data submission. It was just a suggestion if it made it easier for your particular case. Andy

Since you have two data items and a button, I'd probably make a form for each pair, make the button have an onClick function that adds the items to a list, and then an overall submit button to do the submit. Or use a list like the example I posted earlier and have each pair in the list, if it wasn't a big list. So 12s 12l 7s 7l and so forth. On 9/21/2015 1:41 PM, Richard Reina wrote:
