Writing a Basic Authentication System in PHP - Getting the User Login
(Page 3 of 6 )
An HTML form is used to obtain the user's login credentials. The form displays 2 input fields--one to obtain the login ID and another to obtain the password.
<form action="validate.php" method="post">
<label for="userid">ID</label>
<input type="text" name="userid" id="userid" />
<br />
<label for="password">Password</label>
<input type="password" name="password" id="password" />
<br />
<input type="submit" name="submit" value="Submit" />
</form> |
The userid input field accepts the user's login id while the password field will accept the user's password. The password field might show asterisks or dots as the value is entered, but remember that the form will send it's data in clear text. A secure connection should be made using HTTPS. For more information on that subject see my tutorial Generating Your Own Security Certificates For Use With Apache/HTTPS.
The form here submits its information to a script named validate.php as specified by the form's action attribute. It's that script that will be responsible for checking the user's login ID and password in the database and allowing the user to continue.
