Are there any best practices for integrating PHP forms with CMS systems?

When integrating PHP forms with CMS systems, it is essential to ensure that the form data is properly sanitized and validated to prevent security vulnerabilities. One best practice is to utilize the CMS's built-in form processing capabilities to handle form submissions securely. 

// Example of integrating a PHP form with WordPress CMS

// Add a custom form handler function
function custom_form_handler() {
    if( isset( $_POST['submit'] ) ) {
        // Sanitize and validate form data
        $name = sanitize_text_field( $_POST['name'] );
        $email = sanitize_email( $_POST['email'] );

        // Process form data as needed
        // For example, save to database or send email
    }
}

// Hook the custom form handler function to WordPress form submission action
add_action( 'init', 'custom_form_handler' );

// Create a form in a WordPress template
<form method="post">
    <input type="text" name="name" placeholder="Name">
    <input type="email" name="email" placeholder="Email">
    <input type="submit" name="submit" value="Submit">
</form>
