Not with PHP, but with Javascript. PHP is a server-side language, all the code is processed before your browser gets the HTML.

Try using this code:

<html>
<head>
<title>Dynamic Form</title>
<script language="javascript">
var i = 1;
function changeIt()
{

my_div.innerHTML = my_div.innerHTML +"<br><input type='text' name='mytext'+ i>"
i++;
}
</script>
</head>
<body>

<form name="form" action="post" method="">
<input type="text" name=t1>
<input type="button" value="test" onClick="changeIt()">
<div id="my_div"></div>

</body>

you can do that with the use of JavaScript.

try below code: 

function addElement() {
  var ni = document.getElementById('myDiv');
  var numi = document.getElementById('theValue');
  var num = (document.getElementById('theValue').value -1)+ 2;
  numi.value = num;
  var newdiv = document.createElement('div');
  var divIdName = 'my'+num+'Div';
  newdiv.setAttribute('id',divIdName);
  newdiv.innerHTML = 'Element Number '+num+' has been added! <a href=\'#\' onclick=\'removeElement('+divIdName+')\'>Remove the div "'+divIdName+'"</a>';
  ni.appendChild(newdiv);
}

Thanks.

It is possible, but you need to use javascript. Check this for an example.

PHP is run on the server side, you have to do this on the browser side.

If you want things to happen on a webpage without a new page load occurring, you must use JavaScript, which runs in the browser.

Your button that creates new textboxes will need to be attached to a JavaScript event you write to do so.

Your PHP script will have to be updated to look for these new inputs and save them the same way it saved the first one.
