How can developers ensure that hidden values passed via POST are not manipulated by malicious users?

Developers can ensure that hidden values passed via POST are not manipulated by malicious users by using server-side validation and verification. This can involve checking the authenticity of the hidden values before processing them and ensuring that sensitive operations are not solely reliant on hidden values for security. 

// Example of server-side validation and verification for hidden values passed via POST
if(isset($_POST['hidden_value'])) {
    $hidden_value = $_POST['hidden_value'];
    
    // Validate the hidden value before processing
    if(validateHiddenValue($hidden_value)) {
        // Proceed with processing the hidden value
    } else {
        // Handle invalid hidden value
    }
}

function validateHiddenValue($hidden_value) {
    // Add your validation logic here
    // Return true if the hidden value is valid, false otherwise
}
