Hi, as far as I understand Ricky refers to cases when the user submitted a form that failed input validation and we would like to send back the form, but instead of sending back an empty form we would like to send it back with fields already filled out by the values the user already provided. Without using ajax. Gabor On Thu, Jan 28, 2021 at 1:30 AM Andrew Solomon <andrew@geekuni.com> wrote:

Hi Ricky,

I read your question four times and failed to understand it :-)

Maybe an example would help?

Hi! The various templating systems don't seem to be very useful for dealing with generating HTML forms that already have data in them, especially if some of the form needs to be generated programatically. What do people use for this instead?

I would approach this by: * making sure all the html fields have an id * on page load, use jQuery to do a REST call back to the server to work out what to stick in these fields Does that make sense? On Thu, Jan 28, 2021 at 3:29 PM Morse, Richard E.,MGH < REMORSE@mgh.harvard.edu> wrote:

Hi! I'm sorry I wasn't clear...

I'm working on a system to replace a Drupal-based form. I need to have some people go in and partially fill out the form (or, rather, fill out a subset of the possible variables), and then be able to present the form again to other people, who will fill out more of the form — or possibly edit the existing answers while talking with the original submitters. They also need to be able to complete the form in multiple sittings, if necessary.

In addition, the labels of a bunch of the checkboxes and selects will need to be used in an alternate view of the information in the completed form, so what particular values represent needs to be available to the program in a useful way, not tied up in the HTML.

I've played around a bit with the three templating systems included in Dancer2 (Simple, Tiny, Toolkit), and although I can sort of see how to make things work for 'input type="text"' and textareas, creating the checkbox groups, radio groups, and select/multi-select widgets seems either impossible (in Simple and Tiny), or really, really, verbose (in Toolkit).

In a recent project, where I was working directly with Plack, I used HTML::FillInForm. But that was a *much* smaller form, and didn't have as much HTML5 stuff in it — I'm worried about it not understanding newer form widgets, and also it seems counter productive to generate HTML, then reparse the entire output to modify it to add the values, and then regenerate the string. (Also, I'm not 100% clear how to integrate HTML::FillInForm with Dancer2, but that's mostly probably because I haven't tried yet.)

In CGI (yes, I know, but bear with me...) there were affordance functions to generate HTML widgets with existing data. CGI being now deprecated, I was wondering what sorts of things people used for the same purpose now?

Or if there is something like the Drupal "forms" system, that would also be useful?

Thanks, Ricky

Thanks, but for a variety of reasons, I'm trying to minimize the amount of client-side Javascript. (Among other reasons, I may still need to support IE8 (or, rather, IE11 in IE8 compatibility mode).)
