PHP - Cant store record inside database

Question

I have created a html file called contact.html and connectivity.php . Inside the contact.html I set form action="Conectivity.php" . However,when I run contact.html and click send button, it should save the record inside my database, but when i clicked the button it only show me the entire code inside connectivity.php .

Here is my code in connectivity.php :

<?php
define('DB_HOST', 'localhost');
define('DB_NAME', 'practice');
define('DB_USER','root');
define('DB_PASSWORD','');

$con=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die("Failed to connect to MySQL: " . mysql_error());
$db=mysql_select_db(DB_NAME,$con) or die("Failed to connect to MySQL: " . mysql_error());
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];

$query = "INSERT INTO contact (contactName,contactEmail,message)VALUES('$name','$email','$message')";
$result = mysql_query($query);
if($result)
{
    echo "Successfully updated database";
} 
else
{
    die('Error: '.mysql_error($con));
}
mysql_close($con);
?>

You say "it only show me the entire code inside connectivity.php" -- it sounds like you don't have a web server installed and are seeing PHP code, because it's not executing your script. You need to install a web server.

Note: if you access a file like file:///foo/Connectivity.php , you will also have this problem -- it has to be over HTTP for the web server to execute the PHP. You must access the file via HTTP, like http://localhost/Connectivity.php or whatever your local server name is instead of localhost.

Please also check your spelling. Your question says, i set form action="conectivity.php" . Your file is named Connectivity.php -- please confirm that you spelled it correctly in the <form> tag.

Also, don't use mysql_* - use MySQLi or PDO instead. You must use prepared statements; your current code is extremely vulnerable to SQL injection attacks.
