Final answer:
To connect an HTML form to a MySQL database, you need to use a server-side scripting language like PHP. Here's a basic example using PHP.
Step-by-step explanation:
To connect an HTML form to a MySQL database using W3Schools as a reference, create an HTML form (index.html) capturing user input. Designate its "action" attribute to a PHP script (insert.php). In the PHP script, establish a connection to MySQL with appropriate credentials, retrieve form data using the $_POST variable, and execute an SQL INSERT statement to add data to the designated table.
Ensure to replace placeholder values in PHP with your actual database details.
This basic example emphasizes the integration of HTML, PHP, and MySQL for a functional user input system, but real-world applications demand comprehensive security practices like input validation and prepared statements to prevent vulnerabilities.
