What potential issue does the original code snippet have in selecting the date value?

The original code snippet uses the `$_POST` superglobal to directly access the input value without any validation or sanitization. This can lead to security vulnerabilities such as SQL injection or cross-site scripting attacks. To solve this issue, it is important to validate and sanitize user input before using it in the code. One way to do this is by using PHP's `filter_input()` function with appropriate filters. 

// Validate and sanitize the input before using it
$date = filter_input(INPUT_POST, 'date', FILTER_SANITIZE_STRING);

// Use the sanitized input value
echo "Selected date: " . $date;
