Create User Defined Number of Inputs for Website
Question
I am trying to make a website that accepts multiple inputs based on how many the user wants to enter. Lets say they want to enter 4 addresses. I want to be able to handle that input but also if they ask for 10 inputs without having to create pages for each instance. I am new to programming so any insight would be great. Also, I saw some examples of website that I believe use javascript to take in input, create more fields, and process the data without having to switch pages. How would I implement such a thing and would I have to change my data sourcing from php in anyway if I did? Thanks!

With jQuery
index.html
<!DOCTYPE html>
<html class="no-js" lang="en">
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script>
$(function(){
var c = 0;
$("#button1").click(function(){
c = $("#inputs").val();
$("#mydiv").html("");
for(i=0;i<c;i++){
$("#mydiv").append('<input type="text" id="data'+i+'" name="data'+i+'" /><br/>');
}
});
$("#button2").click(function(){
$.post("file.php",$("#form1").serialize(),function(data){
alert(data);
});
});
});
</script>
</head>
<body>
<form id="form1">
Type the number of inputs:
<input type="text" id="inputs" name="inputs" />
<input type="button" id="button1" value="Create" />
<div id="mydiv"></div>
<input type="button" id ="button2" value="Send" />
</form>
</body>
</html>
If you need to process the new inputs with PHP:
file.php
<?php
for( $i=0; $i<$_POST["inputs"] ; $i++){
echo $_POST["data".$i]."\n";
}
?>
