Dynamically adding form inputs and submit using jQuery

You may find a need to allow the user to dynamically add or remove text inputs from your application. This is relatively easy to do using jQuery and using arrays to submit the form data to a PHP page. This tutorial runs through setting up the form with the controls to add, remove and reset the form fields as well as preparing the form variables to be sent using AJAX.

The Code

You won’t need to be a JavaScript master to work out what’s going on here. the first click functions control the number of input fields displayed on the page. Each new input field that’s added is given the ‘dynamic[]‘ array name so the values are concatenated and separated with a comma.

Then once the user submits the form, the form values are pushed into an array which can then be submitted using PHP to your database. You’ll probably need to either store the complete string for example 1,2,3,4,5,6,7 in the database or explode the string using PHP where you can manipulate it further.


	var i = $('input').size() + 1;
	$('#add').click(function() {
		$('<div><input type="text" class="field" name="dynamic[]" value="' + i + '" /></div>').fadeIn('slow').appendTo('.inputs');
	$('#remove').click(function() {
	if(i > 1) {
	$('#reset').click(function() {
	while(i > 2) {
	// here's our click function for when the forms submitted

	var answers = [];
    $.each($('.field'), function() {
    if(answers.length == 0) { 
        answers = "none"; 

	return false;

    How to I make more than one of these boxes with different attributes so I can PHP post it individually?!?!

    by the way, in order to validate this with PHP, use this:

    foreach($_POST['dynamic'] as $value) {
    echo "$value “; // change this to what you want to do with the data
