    Hi!

    Loving the plugin. Great work! I’m currently trying to hook into do_action( 'simpay_process_form', $this ); in order to add some meta data into the transaction info sent to Stripe.

    In my functions file I created the following basic code:

    add_action('simpay_process_form', 'bbs_simpay_process_form');
function bbs_simpay_process_form() {
	$this->metadata = array("special_order_info" => "6735");
}

    Unfortunately this throws the following error:
    Fatal error: Uncaught Error: Using $this when not in object context...
    I tried renaming the function to function bbs_simpay_process_form($this) but that doesn’t work as the hook function happens outside of the scope of the object.

    How do you suggest I go about adding this information into the hook/transaction properly?

    Thanks!
    David

    On a side note, I did end up making it work by using the simpay_payment_metadata filter instead. But curious to learn anyway how to make the action hook work should I need this in the future.
    Thanks!

    @davidbawiec You had the right action hook to start, but good to know the filter hook works as well.

    In your example, you just need to add a parameter to your function and merge with the existing metadata. Here’s what should work:

    function bbs_simpay_process_form( $payment ) {
	$payment->metadata = array("special_order_info" => "6735");

	// Add new metadata to existing metadata before processing payment form.
	$payment->metadata = array_merge( $payment->metadata, $new_metadata );
}
add_action('simpay_process_form', 'bbs_simpay_process_form');

    I just added a more generic example to our code snippet library as well.

    Thanks,

    Dear friends,

    i have today received from wordpress the following message:

    I am absolutely outside the IT area and have so very limited it skills. Really do not know what it says and what I should do. I can have access to the ftp, I understand it is something related to the theme I use but really do not know what to do. Any advice would be so welcome! Thanks so much,

    Cristina
