Question

Id like to make a simple login form for a website

    <form action="ContactFormHandler.php" method="post">
        <table>
            <tr>
                <td>
                    Username:
                </td>
                <td>
                    <input type="text" id="username" name="username" />
                </td>
            </tr>
            <tr>
                <td>
                    Password:
                </td>
                <td>
                    <input type="text" id="password" name="password" />
                </td>
            </tr>
            <tr>
                <td>
                    Your Email:
                </td>
                <td>
                    <input type="text" id="Email" name="Email" />
                </td>
            </tr>
            <tr>
                <td colspan="2" style="text-align: center;">
                    <input type="submit" id="submit" value="Submit" />
                    <input type="reset" id="reset" value="Reset" />
                </td>
            </tr>
        </table>
    </form>
</body>

You see where it says contact form handler? I would like the form, and the file handling the form to be the same file. 2 in 1.

how do I include this contact handler in the same file of the contact form?

<?php
$contactName = $_POST["ContactName"];
$contactEmail = $_POST["ContactEmail"];
$contactPassword = $_POST["ContactLeastFavoriteColor"];
$sql_connection = mysql_connect("localhost", "root", "root");
mysql_select_db("MyRadContactForm", $sql_connection);
$sql = "INSERT INTO MyRadContacts (
            ContactName,
            ContactEmail,
            ContactPassword,
            ContactDateCreated
        )
        VALUES (
            '$contactName',
            '$contactEmail',
            '$contactPassword',
            NOW()
        )";

mysql_query($sql, $sql_connection);
mysql_close($sql_connection);
?>

Make the form submit to its own page

Change the form’s action to action="<?php echo $_SERVER['PHP_SELF'] ?>" to make the form submit to the same page

Process the form within the page

Put a check around your PHP code to see whether or not the form was submitted:

if (isset($_POST['submit'])) {
    [your processing code here]
} else {
    [display form]
}

(be sure to add name="submit" to your submit button)
