Save form's inputs when user proceed to next form - html

I have a very long form, so I need to separate it to different pages.
My questions are:
1) How to save the form input when the user navigate to next form, and when the user back to previous form, the data entered previously will still be there.
2) How can I save the data of the incomplete form and provide the user a link so that he can go to that link and continue to fill in the form before actually submit it.
Please advise me on how to achieve these. Thanks in advance.

Simply submit the form to next form page and in next form page you can populate hidden fields with the received data from form1
form2.php
$form1Field = $_POST;
form2.php
<form action="form3.php">
<input id='form1_name' type='hidden' value='<?=form1Field['name']?>' />
<input id='form12_email' type='text' value='' />
</form>
#katti's suggestion is good, easy way is to make divs for each form and hide using css "display:none" all divs except 1st, then on a click button, hide div1 and show div2 so on. that way you wont need many form and will need less code and faster solution.

You can use hidden fields for this purpose. Or save data in cookies.

You can divide the form by dynamically loading the next part of the form using JavaScript.
And it is a better user experience too not loading a new page completely.
In this case you can save the form content in a JSON object which can be posted to the server once the user hits submit.

How to access required element of HTML in shiny

I am working on form where i am taking inputs from users and all fields are mandatory and have validations like valid emailid, only 6 digit pincode.I have created a form on HTML and all validations are working fine on HTML by using "required" element of HTML which makes input type mandatory also input type email of HTML put all the validations required for an emailid.
But i want to achieve same thing in shiny internal UI form i tried a lot by accessing html tags inside shiny but everytime i am getting error for required element that i placed inside input tag of shiny.
Below attached image is from HTML form that i created using raw HTML but i want to achieve same thing in my shiny internal form.
Code for the above image:
<input type="email" name="emailid" value="" placeholder="Enter valid email id" required>
Can anyone help me how to achieve the same.Any help would be appreciated!
My solution to this would be in two parts. First, I'd put an observer on input$emailid to check that the user has entered a valid email address. If they haven't I'd then use the shinyFeedback package to display a pop-up prompting the user to put things right. You could also use shinyFeedback to display the prompt you show in your screen grab when the input is empty, but my own personal opinion is that that would be overkill.
Something like:
library(shinyFeedback)
observeEvent(input$emailid, {
feedbackDanger(
"emailid",
!isValidEmailAddress(input$emailid),
"Please enter a valid email address"
)
})
To get shinyFeedback to work you need to add useShinyFeedback() at the start of your ui page. Furter details here. Note that isValidEmailAddress() is a function you'll need to write yourself.

How to receive form input from asp form before moving to another page?

I want to receive an input from a form (asp (C#)) and use this information in another page. The form's action is to go to another place.
I tried using:

How to make the html input field allow to be blank, when i click the button?

How to make the html input field allow to be blank, when i click the submit button on the form view?
the idea is when I click the submit button, the input is a must to key in something else the behind code is unable to run, I am using the asp.net and the button is the asp button not html button

I want to allow the new password can be blank
If clearing fields is what you want, use .reset() method.
document.getElementById("YourFormName").reset();
A working fiddle here:

I may comprehend it wrongly as I do not really understand what do you want.
Update (To disable html 5 form validation) :
Add novalidate='' or <form action="yourform.asp" novalidate> to your form.

xPage-Pager Control with html-FORM element does not work

When I add a normal <form> element in my xpage, the pager doesn't work any longer, means I cannot switch to other pages (clicking on "next" or something).
Here is the important part:
<xp:pager id="newsPager" for="newsList" pageCount="4" partialRefresh="true">
//pager stuff.....
</xp:pager>
<form action="#">
//form stuff... contents not important for my issue, I tested it
</form>
When I exclude the form entirely, it works
I use Domino Designer 8.5.3 on windows 7
And the "newsList" is an ID of a repeat-control
Instead of using a passthru form, use a form component:
<xp:form action="#">
// form contents
</xp:form>
This will prevent the rest of the content from being surrounded by a form tag, which also breaks events and data submission, so you'll need to surround the rest of your content in its own form:
<xp:form>
<xp:pager id="newsPager" for="newsList" pageCount="4" partialRefresh="true">
//pager stuff.....
</xp:pager>
<xp:repeat id="newsList">
//repeat contents
</xp:repeat>
</xp:form>
NOTE: do not nest forms inside each other; this confuses browsers, which is why your current design is not functional. Identify, instead, discrete portions of the page that can be safely treated as separate forms and wrap each portion in its own form component.
The XPage renderer automatically adds a form to the page unless you have disabled this in the properties of the Xpage.
This form is used to process all the partial refreshes and submitting of values to the backend. When you add your own form tag the partial refresh used by the pager ( or any xpage component ) no longer has the correct information needed to talk to the server.
if you really need to have your own form tag then I would suggest an iFrame that loads in an external page that contains your form.
i found this and it's work fine for me

What is the best HTML approach when form inputs are spread throughout the page?

I am building a faceted search system that has inputs in a sidebar (the facets are check boxes), and an input in the header of the page (the main query box). All of these inputs are submitted simultaneously when the user submits a search.
The only way I can think of to make this work is to wrap the entire page in an HTML form tag. Something like the following pseudo-html:
<form>
<div id='header'>
<logo/>
<input id='q'/>
<!-- a bunch more stuff -->
</div>
<div id='sidebar'>
<div id='sidebar-facets-subsection'>
<input id='facet1'/>
<input id='facet2'/>
<input id='facet3'/>
<!-- a bunch more stuff -->
</div>
<div id='sidebar-form-subsection'>
<form id='unrelated-form'>
<input id='unrelated-input-1'/>
<input id='unrelated-input-2'/>
</form>
</div>
</div>
<!-- a bunch more stuff -->
</form>
This would work, except for three things:
I need to use other forms in the page, as I've indicated above.
I use different django templates to generate the header and the sidebar, making the templates have dependencies on each other.
It's a real mess since the sidebar is in reality about 100 lines, not three.
Is there a more clever way of doing this that I'm not aware of, or is creating huge HTML forms the norm? In circumstances like this, is it better to use Javascript to somehow generate the input entries in a more normal form? Or is that the only option?
Any creative solutions or ideas?
You can make it work with Javascript without sacrifying accesibility
Put all the checkboxes in the header and wrap them in div
Set up and empty but clean side bar
Using Javascript, move you checkboxes from the header into the side bar
Attach a callback to the form.submit event, and when the user submit the form, cancel the event then, take the data from the search field and the checkboxes and send it as an Ajax POST request.
Using a framework like jQuery, it's a 15 minutes job.
If the user has JS enable, the form will post the request and everything will work. If the user doesn't have javascript enable, the checkboxes will be in the header and so they will work, at just the price of a slightly less elegant design.
But people with Javascript disable are used to design changes so it's ok.
Use javascript to populate a hidden field with a list of this checkboxes name=value pairs on form submit and treat this in serverside code, spliting the string into an array, etc.
Please note that this is not a good aprouch, since you loose accecibility to those with javascript disabled. The form tag is the only accessible way of doing so.
You can try to change the layout, if you can, swaping the checkboxes with links of buttons that filters the data, almost the way most ecommerce sites do out there.
I believe you have two options:
1.) a page wide form element. All "submit" buttons submit to the same form and the server-side script processes the form for all filled elements. By page wide, I'm not being literal... The related inputs all in the same form tag. Other forms are placed in other form tags.
2.) multiple forms, with a client side script which populates hidden form fields with the data from the other form before submission.
1 requires more work, but 2 may not work for every visitor.
Do consider the fact that, just because you have one form container, you don't have to necessarily display everything together for the user. Encapsulate inputs in divs and position them according to your will. It may not be easy, but it's definitely possible.
