WordPress – Contact Form 7 – Get uploaded file issue

Question

Try this

function my_custom_form_submission( $contact_form ) {
    $submission = WPCF7_Submission::get_instance();
    if ( $submission ) {
        $data = $submission->get_posted_data();
        
        $email = isset( $data['your-email'] ) ? sanitize_email( $data['your-email'] ) : '';
        $phone="Nincs megadva";
        $lastname = isset( $data['your-name'] ) ? sanitize_text_field( $data['your-name'] ) : '';
        $firstname = isset( $data['text-532'] ) ? sanitize_text_field( $data['text-532'] ) : '';
        $companyname = isset( $data['text-479'] ) ? sanitize_textarea_field( $data['text-479'] ) : '';
        $created = current_time( 'Y-m-d\TH:i:s' ); 

        $branch = isset( $data['menu-586'] ) ? sanitize_textarea_field( $data['menu-586'] ) : '';
        if ( $branch == 'Divat / Design' ) {
            $flow = 'DivatDesign';
        } else {
            $flow = 'Startup';
        }

        $uploaded_files = $submission->uploaded_files();
        $documents = [];

        if ( ! empty( $uploaded_files ) ) {
            $uploaded_file = $uploaded_files['file-524'];

            // Read file contents
            $file_content = file_get_contents( $uploaded_file );

            if ( $file_content !== false ) {
                // Encode file content in base64
                $base64_file = base64_encode( $file_content );

                // Prepare data array for API
                $documents = [
                    [
                        'FileName' => basename( $uploaded_file ),
                        'MimeType' => mime_content_type( $uploaded_file ),
                        'Base64' => $base64_file,
                    ],
                ];
            }
        }

        if ( wf_checkEmail( $email ) == false ) {
            $userId = saveToWf( $email, $lastname, $firstname );

            // Log the userId for debugging
            error_log( 'User ID: ' . $userId );
            
            if ( $userId ) {
                registerToWf( $email, $lastname, $firstname, $flow, $userId, $companyname, $phone, $attachedfile, $branch, $documents );
            }
        } 
    }
}
add_action( 'wpcf7_before_send_mail', 'my_custom_form_submission' );

Make sure the file-524 matches the name of the file upload field in your Contact Form 7 setup. Also, ensure the file permissions allow reading the uploaded file on the server.

To debug the issue, you can temporarily add error logging to check the contents of $uploaded_files:

error_log( print_r( $uploaded_files, true ) );

This will help you see what $uploaded_files actually contains and adjust your code accordingly.
