Choose send attachment

Hi!

I find this code for choose send attachement :

add_filter( ‘wpcf7_mail_components’, ‘your_custom_callback_function’, 10, 3 );
function your_custom_callback_function( $components, $contact_form, $mail ) {
if ( ‘mail’ == $mail->name() ) {
// do something for ‘Mail’
} elseif ( ‘mail_2’ == $mail->name() ) {
// do something for ‘Mail (2)’
}

return $components;
}

It’s not working for me.

Erreur is PHP Warning: Missing argument 2 and PHP Warning: Missing argument 3 for cf7_sendpdf::your_custom_callback_function()

PHP Fatal error: Call to a member function name() on a non-object for $mail->name()

Can you explain this ? Where is the problem ?

Thanks a lot
