Hi, Freinds in this post we are going to learn How To Post Data using PDO in PHP/MySQL. PDO is an acronym for PHP Data Objects. PDO is a lean, consistent way to access databases. This means developers can write portable code much easier. PDO is not an abstraction layer like PearDB. PDO is a more like a data access layer which uses a unified API.
How To Post Data using PDO in PHP/MySQL
1-Creating Database
- Open PHPMyAdmin in your Browser
- Click on Database Tab Display on Topside
- Give the Database name “pdo”.
- After Creating Database Open it.
- Click on SQL Tab on Top area
- Copy the Below Source Code and paste it.
- Then Click on Go.
-- phpMyAdmin SQL Dump -- version 4.8.4 -- https://www.phpmyadmin.net/ -- -- Host: 127.0.0.1 -- Generation Time: Feb 05, 2019 at 04:44 AM -- Server version: 10.1.37-MariaDB -- PHP Version: 5.6.39 SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO"; SET AUTOCOMMIT = 0; START TRANSACTION; SET time_zone = "+00:00"; /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */; /*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */; /*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */; /*!40101 SET NAMES utf8mb4 */; -- -- Database: `pdo` -- -- -------------------------------------------------------- -- -- Table structure for table `member` -- CREATE TABLE `member` ( `mem_id` int(11) NOT NULL, `firstname` varchar(50) NOT NULL, `lastname` varchar(50) NOT NULL, `age` int(10) NOT NULL, `address` varchar(100) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1; -- -- Dumping data for table `member` -- INSERT INTO `member` (`mem_id`, `firstname`, `lastname`, `age`, `address`) VALUES (4, 'Priyanshu', 'Raj', 18, 'India'), (5, 'Abhimanu', 'Kumar', 25, 'India'), (6, 'Sonu', 'Kumar', 20, 'India'); -- -- Indexes for dumped tables -- -- -- Indexes for table `member` -- ALTER TABLE `member` ADD PRIMARY KEY (`mem_id`); -- -- AUTO_INCREMENT for dumped tables -- -- -- AUTO_INCREMENT for table `member` -- ALTER TABLE `member` MODIFY `mem_id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=7; COMMIT; /*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */; /*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */; /*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */;
OR Import DB File
After Downloading the source code extract it in your root folder.
- Open PHPMyAdmin in your Browser
- Click on Database Tab Display on Topside
- Give the Database name “pdo”.
- After Creating Database Open it.
- Click on Import Tab on Top area
- You can Find Database folder in Downloaded source code where find register.sql file then Select it.
- Then Click on Go.
2- Creating Database Connection
After import Database File then next step is creating a database connection using php copy the below code and save it is as “conn.php”.
<?php
$conn = new PDO( 'mysql:host=localhost;dbname=pdo', 'root', '');
if(!$conn){
die("Fatal Error: Connection Failed!");
}
?>
3 – Creating Index Page
in this step we are creating page layout where you can add user and show all posted data. here the source code. you can copy the below code and save it as index.php.

4 -Post Data using PHP/MySQL with PDO
in this step we are going to post data in PHP into MySQL using PDO. Here the source code you can copy the below code and save it as save_member.php.
<?php
require_once 'conn.php';
if(ISSET($_POST['save'])){
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$age = $_POST['age'];
$address = $_POST['address'];
try{
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "INSERT INTO `member`(firstname, lastname, age, address) VALUES ('$firstname', '$lastname', '$age', '$address')";
$conn->exec($sql);
}catch(PDOException $e){
echo $e->getMessage();
}
$conn = null;
header("location: index.php");
}
?>
