Below is the modified code with Prepared Statement.<\/p>\n

First step is to connect to the database. To do that, we need to define the access details.<\/p>\n

\/\/ Define Database Credentials\n$servername = \"localhost\"; \/\/Server Name\n$username = \"KyleHulse\"; \/\/Username to the DB\n$password = \"(my password)\"; \/\/Password to the DB\n$dbname = \"csdb1082\"; \/\/Name of the Database\n\n\/\/ Create Database Connection\n$conn = new mysqli($servername, $username, $password, $dbname);\n<\/code><\/pre>\n
Now check the connection.<\/p>\n
\/\/ Check connection\nif ($conn->connect_error) {\n    die(\"Connection failed: \" . $conn->connect_error);\n}\n<\/code><\/pre>\n
After this, you run your query. Please note that since this is your personal project, therefore I am using SHA1<\/code> as the hashing of your password. For a bigger project, I recommend to research further on how to secure your password.<\/p>\n
To run the query, first is to prepare it. This is how you do.<\/p>\n
$stmt = $conn->prepare(\"INSERT INTO feedback (user, password, email) VALUES (?, ?, ?)\");\n<\/code><\/pre>\n
In this, you store the statement in $stmt<\/code> variable. The query has INSERT INTO<\/code> followed by the table’s name. In your case it is feedback<\/code>.<\/p>\n
After this, you fill in the table’s fields to be saved in first bracket. In your case it will be (user, password, email)<\/code> followed by VALUES<\/code>.<\/p>\n
After this you add placeholders for the actual values using (?, ?, ?)<\/code>. Please note that the total count of ?<\/code> must match the total count of fields in the previous bracket.<\/p>\n
Now you have to bind the variables to these ?<\/code>. This is done by,<\/p>\n
$stmt->bind_param(\"sss\", $user, $password, $email);\n<\/code><\/pre>\n
Please note that \"sss\"<\/code> are the formats of values passed. Below are the formats.<\/p>\n
i - integer\nd - double\ns - string\nb - BLOB\n<\/code><\/pre>\n
So you need to pass 3 values, therefore you have 3 s<\/code>, followed by the variables where you will store the values from HTML form by,<\/p>\n
$user = $_POST[\"user\"];\n$password = sha1($_POST[\"password\"]); \/\/simplest way to use SHA1 hash.\n$email = $_POST[\"email\"];\n<\/code><\/pre>\n
Now you just need to execute the prepared statement.<\/p>\n
$stmt->execute();\n<\/code><\/pre>\n
That’s it!<\/p>\n
Below is the full code.<\/p>\n
\/\/ Define Database Credentials\n$servername = \"localhost\"; \/\/Server Name\n$username = \"KyleHulse\"; \/\/Username to the DB\n$password = \"(my password)\"; \/\/Password to the DB\n$dbname = \"csdb1082\"; \/\/Name of the Database\n\n\/\/ Create connection\n$conn = new mysqli($servername, $username, $password, $dbname);\n\n\/\/ Check connection\nif ($conn->connect_error) {\n    die(\"Connection failed: \" . $conn->connect_error);\n}\n\n$stmt = $conn->prepare(\"INSERT INTO feedback (user, password, email) VALUES (?, ?, ?)\");\n$stmt->bind_param(\"sss\", $user, $password, $email);\n\n$user = $_POST[\"user\"];\n$password = sha1($_POST[\"password\"]); \/\/simplest way to use SHA1 hash.\n$email = $_POST[\"email\"];\n\n$stmt->execute();\n<\/code><\/pre>\n
Hope this helps.<\/p>\n<\/p><\/div>\n
