This tutorial helps to add or remove textbox dynamically using jQuery and PHP. It also describes how to read the values of dynamically created text boxes and save them to the database.

  1. Save textbox HTML in separate file.
  2. Load and append dynamic textbox.
  3. Remove textbox item on delete event.
  4. Read and insert data into the database on submit.

This screenshot shows the dynamically add input box using jQuery AJAX add more option. The checkboxes before the dynamically added input field rows are used to bulk select the rows to delete.


Database Script

Run this CREATE statement while setting up this example in your local environment.

  `id` int(11) NOT NULL,
  `item_name` varchar(255) DEFAULT NULL,
  `item_price` double DEFAULT NULL

-- Indexes for table `item`

-- AUTO_INCREMENT for dumped tables

-- AUTO_INCREMENT for table `item`

Textbox HTML

Save this code as input.php. This file will be loaded later using jQuery to append textbox HTML code to the target location.

<div class="product-item float-clear" style="clear: both;">
    <div class="float-left">
        <input type="checkbox" name="item_index[]" />
    <div class="float-left">
        <input type="text" name="item_name[]"/>
    <div class="float-left">
        <input type="text" name="item_price[]" />

Load and Append Dynamic Textbox

The textbox markup will be added dynamically by using jQuery append() and load(). The code is,

function addMore() {
    $("<div>").load("input.php", function() {

Remove Textbox

We have the checkbox for each row dynamically added the text box for selecting rows to be removed from the delete event. And script for removing checked items is,

function deleteRow() {
    $('div.product-item').each(function(index, item) {
        jQuery(':checkbox', this).each(function() {
            if ($(this).is(':checked')) {
                $("#delete-button-required").html("Choose at least 1 row.").css("color", "red").hide();
            else {
                $("#delete-button-required").html("Choose at least 1 row.").css("color", "red").show();

Read Dynamic Textbox Input

This is, as usual, what we have seen in several MySQL crud examples. The code is,

if (! empty($_POST["save"])) {
    $connection = mysqli_connect("localhost", "root", "", "dynamic_textbox");
    $itemCount = count($_POST["item_name"]);
    for ($i = 0; $i < $itemCount; $i ++) {
        if (! empty($_POST["item_name"][$i]) || ! empty($_POST["item_price"][$i])) {
            $query = "INSERT INTO item (item_name,item_price) VALUES(?, ?)";
            $statement = $connection->prepare($query);
            $statement->bind_param('si', $_POST["item_name"][$i], $_POST["item_price"][$i]);
            $result = $statement->execute();
        if (! empty($result)) {
            $response = array("type"=>"success", "message"=>"Added successfully.");
        } else {
            $response = array("type"=>"error", "message"=>"Please enter the data.");
