Build CRUD App using Vue.js PHP MySql



This is first tutorial on Vue.js with PHP script and in this tutorial we will make CRUD Application in PHP by using Vue.js and Axios package. For learn any new web technology for web development, then first we have to learn How can we do insert update delete operation with Mysql database. For this also for learn How to use Vue.js for website development, first we want to learn How to create CRUD application using Vue.js. By using CRUD application we will learn Create, Read, Update and Delete mysql data operation by using Vue.js with PHP script. From this post you can easily learn How can we perform insert update delete mysql data operation by using Vue.js with PHP script.

We all know Add, edit and delete feature is mostly used in developing of every dynamic website and by using PHP script we can make dynamic website. But only by using PHP script we can make dynamic website, but on every button click page has been refresh. By using Ajax with PHP script we can improve user experience by performing all operation without page refresh. But here we have use Vue.js and Axios package with PHP script then we can perform all form related operation without refresh of web page just like desktop application. So, here we will make single page CRUD application using Vue.js with PHP script.

In this post, we will learn you, how can we select, insert, update and delete mysql data from database using Vue.js with PHP and Axios package. Here we will use Axios package in place of Ajax for perform all operation without refresh of web page. So, if you wanted to learn How to make Single Page Crud application using Vue.js with PHP script and Mysql database. Below you can find the feature of this PHP CRUD app using Vue.js library.

  1. Fetch Data Mysql Database using Vue.js with PHP
  2. Make Modal in Vue.js
  3. Insert or Add Data using Vue.js with PHP
  4. Update or Edit Data using Vue.js with PHP
  5. Delete or Remove Data using Vue.js with PHP

Build CRUD App using Vue.js PHP MySql




Database


First we have to make table in Mysql database, for this we have to run following SQL script in your Mysql localhost but before run following SQL script, you have to create database and then after run below SQL script. It will make tbl_sample table in your local mysql database.


--
-- Database: `testing`
--

-- --------------------------------------------------------

--
-- Table structure for table `tbl_sample`
--

CREATE TABLE `tbl_sample` (
  `id` int(11) NOT NULL,
  `first_name` varchar(250) NOT NULL,
  `last_name` varchar(250) NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

--
-- Dumping data for table `tbl_sample`
--

INSERT INTO `tbl_sample` (`id`, `first_name`, `last_name`) VALUES
(1, 'John', 'Smith'),
(2, 'Peter', 'Parker'),
(4, 'Donna', 'Huber');

--
-- Indexes for dumped tables
--

--
-- Indexes for table `tbl_sample`
--
ALTER TABLE `tbl_sample`
  ADD PRIMARY KEY (`id`);

--
-- AUTO_INCREMENT for dumped tables
--

--
-- AUTO_INCREMENT for table `tbl_sample`
--
ALTER TABLE `tbl_sample`
  MODIFY `id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=5;





index.php


In this file we have write all client side code like HTML and Vue.js code. For use Vue.js with Axios package, first we have to include following library link at the header of this page.


<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>


For display mysql data on web page, first we have make HTML table and then after by using v-for directive for fetch data from Vue.js placeholder data and print in HTML table.

After this for make Modal in Vue.js. For create modal in Vue.js here we will use Bootstrap modal. For make modal in Vue.js library here we have use transition tag, Under this tag, we have define bootstrap modal code and then after we can make modal in Vue.js

action.php


All php script will be write under this file for make CRUD application. In this file, first we want to make database connection. After this we have to receive Axios request data in json format. For received JSON data at PHP script, we have use file_get_contents() function and then after by using json_decode() function, json string data will be converted into PHP array object. After this, we have write PHP script for Select, Insert, Update and Delete mysql data operation.

action.php

<?php

//action.php

$connect = new PDO("mysql:host=localhost;dbname=testing", "root", "");
$received_data = json_decode(file_get_contents("php://input"));
$data = array();
if($received_data->action == 'fetchall')
{
 $query = "
 SELECT * FROM tbl_sample 
 ORDER BY id DESC
 ";
 $statement = $connect->prepare($query);
 $statement->execute();
 while($row = $statement->fetch(PDO::FETCH_ASSOC))
 {
  $data[] = $row;
 }
 echo json_encode($data);
}
if($received_data->action == 'insert')
{
 $data = array(
  ':first_name' => $received_data->firstName,
  ':last_name' => $received_data->lastName
 );

 $query = "
 INSERT INTO tbl_sample 
 (first_name, last_name) 
 VALUES (:first_name, :last_name)
 ";

 $statement = $connect->prepare($query);

 $statement->execute($data);

 $output = array(
  'message' => 'Data Inserted'
 );

 echo json_encode($output);
}
if($received_data->action == 'fetchSingle')
{
 $query = "
 SELECT * FROM tbl_sample 
 WHERE id = '".$received_data->id."'
 ";

 $statement = $connect->prepare($query);

 $statement->execute();

 $result = $statement->fetchAll();

 foreach($result as $row)
 {
  $data['id'] = $row['id'];
  $data['first_name'] = $row['first_name'];
  $data['last_name'] = $row['last_name'];
 }

 echo json_encode($data);
}
if($received_data->action == 'update')
{
 $data = array(
  ':first_name' => $received_data->firstName,
  ':last_name' => $received_data->lastName,
  ':id'   => $received_data->hiddenId
 );

 $query = "
 UPDATE tbl_sample 
 SET first_name = :first_name, 
 last_name = :last_name 
 WHERE id = :id
 ";

 $statement = $connect->prepare($query);

 $statement->execute($data);

 $output = array(
  'message' => 'Data Updated'
 );

 echo json_encode($output);
}

if($received_data->action == 'delete')
{
 $query = "
 DELETE FROM tbl_sample 
 WHERE id = '".$received_data->id."'
 ";

 $statement = $connect->prepare($query);

 $statement->execute();

 $output = array(
  'message' => 'Data Deleted'
 );

 echo json_encode($output);
}

?>


Remaining source code will be added very soon.
