Solution:
To automate the process of data deletion in MariaDB, we can create a simple web interface using PHP and HTML that will trigger a scheduled task or cron job in the server to delete the data at a specific time interval.
Here are the steps to create the web interface and automate the data deletion process:
1. Create a database in MariaDB:
Start by creating a database in MariaDB where you will keep all the data that needs to be deleted. You can name this database as "autodelete" for reference.
2. Create a table for storing data with a timestamp:
In the autodelete database, create a table named "data" with the following fields:
- id (auto-increment primary key)
- data (to store the data that needs to be deleted)
- timestamp (to store the time when the data was inserted)
This will help in identifying the old data that needs to be deleted based on the timestamp.
3. Create a basic web interface:
Next, create a basic PHP web page with a form to input the data that needs to be deleted. On submission, the data will be stored in the "data" table along with the current timestamp.
4. Create a scheduled task or cron job:
In the server, set up a scheduled task or a cron job to run a PHP script at a specific time interval, let's say every hour.
5. Write the PHP script to delete data:
In the scheduled task or cron job, call a PHP script that will connect to the autodelete database and run a query to delete the data based on the timestamp. The script can be something like this:
$connection = mysqli_connect("localhost", "username", "password", "autodelete");
$current_time = time(); // get current timestamp
$query = "DELETE FROM data WHERE timestamp <= DATE_SUB('$current_time', INTERVAL 1 HOUR)"; // delete data older than 1 hour. You can change the time interval as per your requirement.
$result = mysqli_query($connection, $query);
if (!$result) {
// error handling
} else {
// data deletion successful
}
6. Test the web interface and scheduled task:
Test the web interface by submitting some data. Check if the data is stored in the "data" table and if it gets deleted after an hour. You can also test the scheduled task by manually triggering it.
7. Add error handling and security measures:
Add proper error handling in the PHP script and make sure to sanitize user input to prevent any SQL injection attacks.
With this solution, you will have a web interface where you can input the data that needs to be deleted and a scheduled task that will run at a specific time interval to delete the data. You can schedule the task to run every hour, every day, or any other time interval as per your requirement.
Note: This solution is just a basic example. You can modify it as per your project requirements. Also, make sure to test the solution thoroughly before implementing it on a production server.
