I have a Form:

<form action="reminder.php" method="post">
		Name: <input type ="text" name="name" value="" /> <br />
		Name: <input type="text" name="customer" /><br />
		Email: <input type="text" name="email" /> <br />
		Phone Number: <input type="text" name="phone" /> <br />
		Vehicle Make/model: <input type="text" name="car" /> <br />
		Registration: <input type="text" name="registration" /> <br />
		Date <input type="date" name="date" /> <br />
		<br />
		<input type="submit" name="submit" value="Submit" />
I have set the action to reminder.php which has all commands and relevant "stuff". There is also another file named "databases" which has the database name, username, password, etc...

How can I link the HTML form so the contents publish to the database?
