In this tutorial, we are going to learn how to insert data in the MySQL database using PHP Ajax.

OK, Mainly Ajax is used for sending and receiving data from the server without reloading the page and the same page easily insert multiple data.

$ads={1}

First, we need to create three empty files 

  • dbconfig.php
  • index.php
  • savedata.php

 

And then, I already created a database and I named it studentresults and create a table student.

CREATE A TABLE:



CREATE TABLE student (
  id int(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
  name varchar(100) NOT NULL,
  email varchar(50) NOT NULL,
  mobileno varchar(100) NOT NULL,
  city varchar(50) NOT NULL
);


DBCONFIG.PHP



<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname="studentresults";

$conn = mysqli_connect($servername, $username, $password, $dbname);

?>


INDEX.PHP

Here, JQuery Ajax is used to post the data in database using PHP without page reload. 
 



<script>
$(document).ready(function() {
$('#submit').on('click', function() {
var name = $('#name').val();
var email = $('#email').val();
var mobileno = $('#mobileno').val();
var city = $('#city').val();
if(name!="" && email!="" && mobileno!="" && city!=""){
	$.ajax({
		url: "savedata.php",
		type: "POST",
		data: {
			name: name,
			email: email,
			mobileno: mobileno,
			city: city				
		},
		cache: false,
		success: function(data){
			    $('#success').show();
                $('#success').html(data);
				window.setTimeout(function() {
                $(".close").fadeTo(100, 0).slideUp(100, function(){
                $(this).remove();  						
			    });
}, 5000);
			}
	});
	}
	else{
		alert('Please fill all the field !');
	}
});
});
</script>

SAVEDATA.PHP



<?php
	include 'dbconfig.php';
	$name=$_POST['name'];
	$email=$_POST['email'];
	$mobileno=$_POST['mobileno'];
	$city=$_POST['city'];
	$sql = "INSERT INTO student(name, email, mobileno, city) 
	VALUES ('$name','$email','$mobileno','$city')";
	if (mysqli_query($conn, $sql)) 
	{
		echo "Data Inserted Successfully..!";
	} 
	else 
	{
		echo "Error Occurred while Inserting...!";
	}
	mysqli_close($conn);
?>
