How to Insert Data to MySQL Database from PHP using jQuery Ajax
Follow the below steps and how to post form data and insert in MySQL database using jQuery ajax in PHP:
- Step 1 – Create Database And Table
- Step 2 – Create a Database Connection File
- Step 3 – Create An Ajax POST Form in PHP
- Step 4 – Create An Ajax Data Store File
First of all, go to your PHPMyAdmin and create a table name customers with the following fields: name, email, message.
Step 1 – Create Database And Table
First of all, navigate to your phpmyadmin panel and create database and table using the following sql queries:
CREATE DATABASE my_db;
CREATE TABLE `customers` (
`id` int(10) UNSIGNED NOT NULL,
`name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
`email` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
`message` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
`created_date` date DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
Step 2 – Create a Database Connection File
In this step, you will create a file name db.php and update the below code into your file.
The below code is used to create a MySQL database connection in PHP. When you insert form data into MySQL database, there you will include this file:
<?php
$servername='localhost';
$username='root';
$password='';
$dbname = "my_db";
$conn=mysqli_connect($servername,$username,$password,"$dbname");
if(!$conn){
die('Could not Connect MySql Server:' .mysql_error());
}
?>
Step 3 – Create An Ajax Post Form in PHP
In this step, you need to create an ajax form and update the below code into your ajax-form.php file.
<!DOCTYPE html>
<html>
<head>
<title>Ajax POST request with JQuery and PHP - Tutsmake</title>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<style type="text/css">
body {
font-family: calibri;
}
.box {
margin-bottom: 10px;
}
.box label {
display: inline-block;
width: 80px;
text-align: right;
margin-right: 10px;
}
.box input, .box textarea {
border-radius: 3px;
border: 1px solid #ddd;
padding: 5px 10px;
}
.btn-submit {
margin-left: 90px;
}
</style>
</head>
<body>
<h2>Ajax POST request with JQuery and PHP - <a href="https://www.geeksforgeeks.org/category/php/">Tutsmake.com</a></h2>
<form>
<div class="box">
<label>First Name:</label><input type="text" name="firstName" id="firstName" />
</div>
<div class="box">
<label>Last Name:</label><input type="text" name="lastName" id="lastName" />
</div>
<div class="box">
<label>Email:</label><input type="email" name="email" id="email" />
</div>
<div class="box">
<label>Message:</label><textarea type="text" name="message" id="message"></textarea>
</div>
<input id="submit" type="button" class="btn-submit" value="Submit" />
</form>
<script>
$(document).ready(function() {
$("#submit").click(function() {
var firstName = $("#firstName").val();
var lastName = $("#lastName").val();
var email = $("#email").val();
var message = $("#message").val();
if(firstName==''||lastName==''||email==''||message=='') {
alert("Please fill all fields.");
return false;
}
$.ajax({
type: "POST",
url: "store.php",
data: {
firstName: firstName,
lastName: lastName,
email: email,
message: message
},
cache: false,
success: function(data) {
alert(data);
},
error: function(xhr, status, error) {
console.error(xhr);
}
});
});
});
</script>
</body>
</html>
Step 4 – Create Ajax Form PHP File
Now you need to create a new file name store.php and update the below code into your store.php file.
The below code is used to store form data into a MySQL database table name customers. If form successfully submitted to the database, it will return success message otherwise it returns an error.
<?php
require_once "db.php";
$name = mysqli_real_escape_string($conn, $_POST['firstName'] . " " . $_POST['lastName']);
$email = mysqli_real_escape_string($conn, $_POST['email']);
$message = mysqli_real_escape_string($conn, $_POST['message']);
if(mysqli_query($conn, "INSERT INTO customers(name, email, message) VALUES('" . $name . "', '" . $email . "', '" . $message . "')")) {
echo '1';
} else {
echo "Error: " . $sql . "" . mysqli_error($conn);
}
mysqli_close($conn);
?>
