What are the risks of including multiple variables in the name attribute of a select field in PHP?

Including multiple variables in the name attribute of a select field in PHP can lead to potential security vulnerabilities such as injection attacks or data manipulation. To mitigate this risk, it is recommended to sanitize and validate the input data before using it in the name attribute.

// Sanitize and validate input data before using it in the name attribute
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$value = filter_var($_POST['value'], FILTER_SANITIZE_STRING);

echo '<select name="' . $name . '">';
echo '<option value="' . $value . '">Option 1</option>';
echo '</select>';
