Codeigniter - add/remove multiple input fields dynamically with jquery
In this example, i will help you learn dynamically add multiple input fields and submit to database with jquery and codeigniter 3. we can add remove input fields dynamically with jquery and submit to database in codeigniter.
In this example, we will create one table "tagslist" and create one form for add multiple records in single form. we will write add more input fields js code in view file. Then we will store data in database.
Step 1: Download Fresh Codeigniter 3
In First step we will download fresh version of Codeigniter 3, so if you haven't download yet then download from here : Download Codeigniter 3.
Step 2: Create Table
In first table we must have one table with some dummy records. For this example i created "tagslist" table, so run bellow query:
CREATE TABLE IF NOT EXISTS `tagslist` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci AUTO_INCREMENT=24 ;
Step 3: Add Route
In this step you have to add some route in your route file. So first we will create route for add more input fields example.so put the bellow content in route file:
application/config/routes.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
$route['default_controller'] = 'welcome';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
$route['add-more'] = "AddMoreController";
$route['add-more-post']['post'] = "AddMoreController/storePost";
Step 4: Create Controller
In this step, we have to create "AddMoreController" controller with index() and storePost(). so put bellow code in this file:
application/controllers/AddMoreController.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class AddMoreController extends CI_Controller {
/**
* Get All Data from this method.
*
* @return Response
*/
public function __construct() {
parent::__construct();
$this->load->database();
}
/**
* Get All Data from this method.
*
* @return Response
*/
public function index()
{
$this->load->view('addMore');
}
/**
* Get All Data from this method.
*
* @return Response
*/
public function storePost()
{
if(!empty($this->input->post('addmore'))){
foreach ($this->input->post('addmore') as $key => $value) {
$this->db->insert('tagslist',$value);
}
}
print_r('Record Added Successfully.');
}
}
Step 5: Create View
In this step we will create addMore.php view file . In this file we will write design of html form with add more input fields code. So let's update following file:
application/views/addMore.php
<!DOCTYPE html>
<html>
<head>
<title>PHP Codeigniter - Dynamically Add or Remove input fields using JQuery</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" />

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<h2 align="center">PHP - Dynamically Add or Remove input fields using JQuery</h2>
<div class="form-group">
<form name="add_name" method="POST" action="/add-more-post">
<div class="table-responsive">
<table class="table table-bordered" id="dynamic_field">
<tr>
<td><input type="text" name="addmore[][name]" placeholder="Enter your Name" class="form-control name_list" required="" /></td>
<td><button type="button" name="add" id="add" class="btn btn-success">Add More</button></td>
</tr>
</table>
<input type="submit" name="submit" id="submit" class="btn btn-info" value="Submit" />
</div>
</form>
</div>
</div>
<script type="text/javascript">
$(document).ready(function(){
var i=1;
$('#add').click(function(){
i++;
$('#dynamic_field').append('<tr id="row'+i+'" class="dynamic-added"><td><input type="text" name="addmore[][name]" placeholder="Enter your Name" class="form-control name_list" required /></td><td><button type="button" name="remove" id="'+i+'" class="btn btn-danger btn_remove">X</button></td></tr>');
});
$(document).on('click', '.btn_remove', function(){
var button_id = $(this).attr("id");
$('#row'+button_id+'').remove();
});
});
</script>
</body>
</html>
