How to get data user input data from my webpage

I have made a form in my site, which will allow me to get suggestions about Rubik's cube algorithms, but how to know what input the user has? For better understanding, I've given the code below:
<form method="POST">
<label>Your name: </label><br>
<input type="text" name="name" placeholder="Your Name" required><br><br>
<label>Your E-mail: </label><br>
<input type="email" name="email" placeholder="email#domain.com" required><br><br>
<label>Select puzzle: </label><br>
<input type="radio" name="2x2" value="2x2">2x2<br>
<input type="radio" name="3x3" value="3x3">3x3<br><br>
<label>Select set/subset: </label><br>
<input list="set"><br><br>
<datalist id="set">
<option>Ortega OLL</option>
<option>Ortega PBLL</option>
<option>CLL</option>
<option>EG-1</option>
<option>EG-2</option>
<option>F2L</option>
<option>OLL</option>
<option>PLL</option>
<option>COLL</option>
<option>WV</option>
</datalist>
<label>Your Alg: </label><br>
<input type="text" name="alg"><br><br>
<input type="submit" name="submit" class="w3-black w3-button w3-hover-white w3-hover-text-blue w3-text-white">
</form>

Please add action attribute to your form tag and on submit here is the example
<form action="getvalue.php" method="post">
</form>
Note: Every form element must have unique name .
after adding action attribute then create getvalue.php file and add following code in to it
<?php
print_r($_POST);
?>
Above code will give all the form field values
do let me know if it was helpfull...

I'm not sure exactly what you want to do, but here is an example of a form that submits to itself. This will allow you to remain on the same page after the form has been submitted. You can change what the user sees to indicate that the form was done successfully/etc. I have tested this code and it works.
<main>
<?php
// When the form is submitted
if (isset($_POST["submitButton"])){
//Do something with the data from the form - you don't have to print it out.
//This is all done on the server.
//Connect to DATABASE, send an EMAIL, VALIDATE the form, etc.
print("<pre>");
print_r($_POST); // for all GET variables
print("</pre>")
?>
<!-- This HTML will be visible to the user after the form has been submitted. -->
<h1>The form has been submitted successfully!</h1>
<?php
}else{ //If the form has not been submitted
?>
<form method = "post" >
First name:<br>
<input type="text" name="firstname" value="Mickey">
<br>
Last name:<br>
<input type="text" name="lastname" value="Mouse">
<br><br>
<input type="submit" id = "submitButton" name = "submitButton" value="Submit">
</form>
<?php
} //End else
?>
</main>

Posting button value from an HTML form controlled by Javascript

As the user fills out the form, I have some buttons that dynamically add new questions. However, I can't get the value of these buttons to Post to the subsequent PHP page (all the other information posts fine).
In the example below, I'm not able to get the value of "add_email" in "process-form.php" via $_POST['add_email'];
Thanks in advance for your help. In reduced form, it looks like this:
HTML form
<form id="form" class="form" action="process-form.php" method="POST">
<input id="name" name="name" type="text" placeholder="Name">
<!-- Yes/No buttons asking if the user wants to enter their email-->
<div id="form_email">
<h4>Do you want to enter your email?</h4>
<input type="button" class="btn" id="add_email" name="add_email" value="Yes" onclick="showEmailQ(this.value)"></input>
<input type="button" class="btn" id="add_email" name="add_email" value="No" onclick="showEmailQ(this.value)"></input>
</div>
<input type="submit" class="btn" value="Submit »">
</form>
Javascript
<script>
//Function to process whether user wants to enter email and then display value
function showEmailQ(value){
var table_row = document.getElementById("form_email");
if(value == "Yes"){
table_row.innerHTML = '<input id="email" name="email" type="text" placeholder="Email">';
}
else{
table_row.innerHTML = '<p>You have chosen not to enter your email</p>';
}
}
</script>
PHP
//process-form.php
session_start();
$enteredEmail = $_POST['add_email'];
echo $enteredEmail; // Nothing prints to screen

You're destroying your form by overwriting the inputs with
table_row.innerHTML = '<input id="email" name="email" type="text" placeholder="Email">';
So maybe change the input name to match
table_row.innerHTML = '<input id="email" name="add_email" type="text" placeholder="Email">';

how to give name in auto submit form javascript

This is my code that I am using to submit form with post value
<form action="<?php echo DOMAIN; ?>contact/booking-form.php" method="post">
<input type="text" name="name" value="<?php echo $name; ?>" />
<input type="text" name="email" value="<?php echo $email; ?>" />
<input type="submit" name="submit" id="submit" />
<script>document.getElementById('submit').submit();</script>
</form>
Can anybody help me to pass name="submit" value of submit button to another page?

A submit button is only going to be a successful control if it is used to submit the form (and even then only if it has a name and a value … which yours does not).
If you want submit=submit in your form data when you submit the form with JavaScript, then don't use a submit button to put that data in the form in the first place. Use a hidden input.
<input type="submit">
<input type="hidden" name="submit" id="submit" value="submit">
Then you have two other problems.
First, submit is a method of form elements, not inputs. So you need to change your script to call the right element.
<script>document.getElementById('submit').form.submit();</script>
Second, if a form has a control called submit then that will clobber the submit method. So you need to get one from a different form (not supported in old versions of Internet Explorer):
<script>
var form = document.getElementById('submit').form;
var submit_method = document.createElement("form").submit;
submit_method.call(form);
</script>

<form id=submit action="<?php echo DOMAIN; ?>contact/booking-form.php" name="form1" method="post">
<input type="text" name="name" value="<?php echo $name; ?>" />
<input type="text" name="email" value="<?php echo $email; ?>" />
</form>
<script >
document.form1.submit()
</script>

there is no sumit button in your code. first add in html
<input type="submit" value="submit" id="submit"/>
<script>
document.getElementById("submit").value = "newSubmitButtonValue";
</script>

Form post Send data to another page , verify and then post

I have a form with ,
In the form after user clicks on Submit , he will be taken to another page which would show all the data entered, Which would allow the user to verify the content.(User will have a look at the content , to see what he entered is correct).
Once user verifies he would submit the data and Insert to DB should be done.
I want to know a method in which i could carry on the approach, to do this.
How can i implement this
EDIT MORE EXPLAIN
addemp.php
The Main Div With Form
<div class="panel-body">
<form>
Employee : <input Type="text" id="name">
<input type="submit" value="check">
</div>
The Second Div in the same form should show once submit is clicked
<div class="submit panel-body">
<form>
Employee : <Employee Name asin main div>
<input type="submit" > <--! this submit would post data
</form>
</div>
how to pass the value from 1st div to the second , and from the second INSERT to db.how can i do without page refresh ?

Use following script on location file
$action='';
if(isset($_POST['submit'])){
//create form here
//Change the action of form
$action = 'save.php';
}
echo '<form method="POST" action="'.$action.'">
<input type="text" name="nric" value="'.isset($_POST['nric'])?$_POST['nric'].'" />
<input type="text" name="empName" value="'.isset($_POST['empName'])?$_POST['empName'].'" />
<input type="text" name="location" value="'.isset($_POST['location'])?$_POST['location'].'" />
<input type="submit" value="Submit"/>
</form>';

EDIT: You don't need to use a form in this case. You can simply use JQuery to show the data from text boxes in a DIV and a button that will POST the data for you on the server.
<input type="text" name="nric" id="nric" />
<input type="text" name="empName" id="empName" />
<input type="text" name="location" id="location" />
<input id="sndData" type="button" value="Submit" />
<div id="showData"></div>
JQuery:
$('#sndData').click(function(){
var makeData = "<p>NRIC: "+$('#nric').val()+"</p><p>Employee Name: "+$('#empName').val()+"</p><p>Location: "+$('#location').val()+"</p>";
$('#showData').html(makeData);
});
When you've done that, just create/show a HTML button that will POST the data for you.

Realtime form - on submit clear textfield

I have been looking through StackOverflow a lot and found SOME solutions but they don't work for me :( Probably because I can't place the strings of code correctly.
I have a form which submits content to a database - and a script that loads the database inputs into a div below the form. It works realtime with a small delay.
<div id="addCommentContainer">
<form id="addCommentForm" method="post" action="">
<div>
<input type="hidden" name="name" value="<?php echo $loggedInUser->display_username; ?>" id="name" />
<input type="hidden" name="email" value="<?php echo $loggedInUser->email; ?>" id="email" />
<textarea name="body" id="body" cols="20" rows="5"></textarea>
<input type="submit" id="submit" value="Submit" />
</div>
</form>
It works. I also have this script:
http://sandbox.jinoh.dk/script.js
I tried a solution onclick - but it made the content disappear not being posted. I tried onsubmit - but it didn't work. What I want is the "comment" to be posted and then disappear from the form aka the form to be cleared.
Chatchatchat-div is the one that the comments are loaded into.

$('#addCommentForm').submit(function(e){
var form = this;
.....
....
$.post('submit.php',$(this).serialize(),function(msg){
if(msg.status){
form.reset(); // if you want to reset on msg status
}
....
});
this.reset(); // just reset the form what happen
});
