What are common mistakes when inserting radio group values into a MySQL database using PHP?

One common mistake when inserting radio group values into a MySQL database using PHP is not properly handling the selected value from the radio group. To solve this, you need to retrieve the selected value from the radio group and then insert it into the database using prepared statements to prevent SQL injection. 

// Retrieve the selected value from the radio group
$selectedValue = $_POST['radio_group_name'];

// Prepare the SQL statement using prepared statements
$stmt = $pdo->prepare("INSERT INTO table_name (column_name) VALUES (:selectedValue)");

// Bind the selected value parameter
$stmt->bindParam(':selectedValue', $selectedValue);

// Execute the statement
$stmt->execute();
