How do i merge 2 web forms into 1? - forms

I need to merge these 2 forms into 1 so it passes the email address to all 3 sources.
Is it possible?
Form 1:
<form method="post" id="transparent_redirect_form" name="transparent_redirect_form" action="https://joinalpha.com/launch/signup.php/taster">
<input type="text" id="signup_email_address" name="signup_email_address" placeholder="you#business.com" />
<input type="submit" value="Subscribe" />
</form>
Form 2:
<form method="post" action="http://joinalpha.com/blog/signup/"><input type="hidden" name="ip" value="213.106.180.209" />
<input type="text" name="email" id="s2email" value="you#business.com" onfocus="if (this.value == 'you#business.com') {this.value = '';}" onblur="if (this.value == '') {this.value = 'you#business.com';}" />
<input type="submit" name="subscribe" value="Subscribe" />
</form>
Each form has only one field and one action - to send the email address somewhere...
Any clues how i do this?

I would suggest to use javascript.
Create a button or something outside of the form, then invoke the submit of the form, then use the DOM to change the action in the form, and call submit again.

Form not submitting with query parameters set with "asp-route" despite being in action

UPDATE: per this response this is behavior of HTML5? I tried setting the parameters in hidden inputs and that works. Doesn't make much sense to me, but what do I know.
I have my form for a "next page" button set up like this:
<form id="next" method="get"
asp-controller="Search"
asp-action="Cities"
asp-route-sortOrder="#ViewData["CurrentSort"]"
asp-route-currentFilter="#ViewData["CurrentFilter"]"
asp-route-pageNumber="#(Model.PageIndex + 1)">
<input form="next" type="submit" class="page-btn" disabled="#nextDisabled" value="Next" />
</form>
When I inspect the page, the form has the correct action url (example):
/Search/Cities?currentFilter=Test&pageNumber=2
But the request actually being made is to
/Search/Cities?
But when it hits the controller, all of the parameters are null. Here is the top of my controller:
[Route("Search/Cities")]
public ActionResult Cities(string SearchString, string sortOrder, string currentFilter, int? pageNumber)
I'm not sure what I'm missing here.
you have 3 choices. This code was tested
first the most popular, you have to use post
<form id="next" method="post"
asp-controller="home"
asp-action="test"
asp-route-sortOrder="CurrentSort"
asp-route-currentFilter="CurrentFilter"
asp-route-pageNumber="1">
<label for="searchString">Search</label>
<input type="text" id="searchString" name="searchString"><br><br>
<input form="next" type="submit" class="page-btn" value="Next" />
</form>
in this case searchingString will be sent in a request body, all another params in a query string
second
<a href="/Home/Test?sortOrder=CurrentSort&currentFilter=CurrentFilter&pageNumber=2">
<button class="page-btn">Next</button>
</a>
the second option will generate get request if it is so important for you, but you will not be able post search string except using ajax.
third, you can use get, but route params should be in the inputs, probably hidden, search string will have a visible input
<form id="next" method="get"
asp-controller="home"
asp-action="test">
<input type="hidden" id="sortOrder" name="sortOrder" value="CurrentSort" />
<input type="hidden" id="currentFilter" name="currentFilter" value="CurrentFilter" />
<input type="hidden" id="pageNumber" name="pageNumber" value="23" />
<label for="searchString">Search</label>
<input type="text" id="searchString" name="searchString"><br><br>
<input form="next" type="submit" class="page-btn" value="Next" />
</form>
in this case nothing will be inside of the body, everything in a query string including searchString.

Required for the first or second input form

I use Bootstrap 4.5, where it is possible to check the filling of the form, for example by inserting required.
<input type="text" class="form-control" name="name_1" required>
How can I please check where I need to have input #1 OR input #2 filled in?
<input type="text" class="form-control" name="name_1">
<input type="text" class="form-control" name="name_2">
if you want to check whether the input#1 OR input#2 is filled. I recommend you to write a piece of javascript code to check that. if you are familiar with java script, create a separate javascript file and write a function to validate. or else you can just put a script tag inside the head tag as follows.
Javascript Validation:
<head>
<script>
function validateForm(){
if(document.myform.input1.value == "" || document.myform.input2.value == ""){
alert("Both input1 and input2 should not be empty!");
}
}
</script>
</head>
HTML form:
<form name="myform" method="post" onsubmit="validateForm()" >
Input1: <input type="text" name="input1"><br/>
Input2: <input type="text" name="input2"><br/>
<input type="submit">
</form>

Passing Text into URL from a Form

I'm trying to insert a variable collected from a form into a URL, but I don't want the "?variable=value" part of the URL.
<form action="http://www.example.com/<?php echo htmlspecialchars($_GET['entry']);?>/" method="GET">
<input type="text" value="" name="entry" id="entry">
<input type='submit'>
</form>
Is there any easy way to do this? I want the browser to go to the following URL when the user types "whatever"
http://www.example.com/whatever/
Edit:
I've changed the code to the following, which seems to work, but have I now introduced a script vulnerability?
<form onSubmit=" location.href = 'https://www.example.com/' + document.getElementById('entry').value + '/' ; return false; ">
<input type="text" value="" name="entry" id="entry" placeholder="Your Promo Code">
<input name="promoSubmit" type="submit" value="Buy Now">
</form>
you could use javascript for this kind of tasks, i don't see why would you involve server side for such thing
but the easiest answer will be like:
<script>
function go(){
window.location='http://www.example.com/'+document.getElementById('url').value;
}
</script>
<input type='text' id='url'>
<button id='btn_go' onclick='javascript:go();'>Go</button>

Keep checkbox checked AND only check 1 checkbox per group

I'm looking to combine two things:
a) ensure that when a checkbox is checked, it remains checked after submit, AND
b) only allow one checkbox per group (e.g. the one below) be allowed to be checked at once. I can't use radio buttons unfortunately!
I can do a) & b) in isolation but unfortunately can't seem to combine them! Please help?
<form>
<input type="checkbox" name="a" value="low" <?php if(isset($_POST['a'])) echo "checked='checked'"; ?>/>
<input type="checkbox" name="b" value="mid" <?php if(isset($_POST['b'])) echo "checked='checked'"; ?>/>
<input type="checkbox" name="c" value="hi" <?php if(isset($_POST['c'])) echo "checked='checked'"; ?>/>
</form>
Using jQuery, I was able to create a function that will allow only one checkbox to be clicked at a time.
$('.check').click(function(){
if($('.check:checked').length == 1){
$('.check:not(:checked)').attr('disabled',true);
}
else if($('.check:checked').length == 0){
$('.check:not(:checked)').removeAttr('disabled');
}
});
<p>Check a box</p>
<input type="checkbox" class="check" />
<input type="checkbox" class="check" />
<input type="checkbox" class="check" />

JSP - check form submission

Let say I have a simple form with no required fields:
<form action="index.jsp" method="post">
<input type="text" name="firstName" />
<input type="text" name="lastName" />
<input type="text" name="email" />
<input type="submit" value="submit" />
</form>
I want to check if the form was submitted by checking the submit parameter (because it's always present). In PHP I can do a simple
if ( $_POST['submit'] )
but the request.getParameter("submit") doesn't seem to work.
So what's the best way to check if a form was submitted?
You need to give the input element a name. It's the element's name which get sent as request parameter name.
<input type="submit" name="submit" value="submit" />
Then you can check it as follows:
if (request.getParameter("submit") != null) {
// ...
}
You perhaps also want to check if "POST".equalsIgnoreCase(request.getMethod()) is also true.
if ("POST".equalsIgnoreCase(request.getMethod()) && request.getParameter("submit") != null) {
// ...
}
Better, however, would be to use a servlet and do the job in doPost() method.
You can try this way:-
if ("POST".equalsIgnoreCase(request.getMethod())) {
// Form was submitted.
} else {
// It may be a GET request.
}
