In this post, we’re going to learn how to save data automatically in a database at specific time intervals using Ajax Jquery with PHP and Mysql. This type of functionality you have seen in the WordPress Admin side, any modern editor. However, also on the Admin side when we produce a new post also after a specific interval of time it’ll save as a draft of our post or page automatically in Database If you have used Wordpress CMS. So our data will safe if we forget to publish our content and we come after some time also our content will be placed in Database as a draft. So, This type of functionality we’re going to learn in this post. In this post, We’ll describe a simple post illustration. We have a simple form for posting simple compositions with titles and descriptions.
When a user enters the title and description then after some time interval post automatically saves it into the database table. This effect happens only after the user enters the post title and description. In this tutorial, if a post enters for the first time also it fits into the database table but if the post formerly fitted also it’ll modernize that post data a regular time intervals.
Create Below Table.
CREATE TABLE `posts` ( `id` int(11) NOT NULL AUTO_INCREMENT, `title` varchar(100) NOT NULL, `description` text NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1;
Create config.php file and add below line of code.
$host = "localhost"; /* Host name */
$user = "root"; /* User */
$password = ""; /* Password */
$dbname = "auto_save_demo"; /* Database name */
$con = mysqli_connect($host, $user, $password,$dbname);
