Small Issues Regarding Custom Gateway

1. Catching the Results Gateway

I copied the paypal gateway. The gateway generates a return url that looks something like this: http://mydomain.com/paymentreturn/mygateway

I know there is a function that handles this in the paypal gateway, ‘ handle_paypal_return()’. The problem is, in my gateway, my function to handle the results is not working. Perhaps I missed out a hook somewhere.

Please help.

Thanks.

2. Creating the gateway as a plugin

I just copied the paypal gateway (in the memberships plugin). I would like to package it as a seperate so that it doesn’t disappear when updating membership.

How can I do this? is there a do_action I can hook into? or a function I should call?

I know there is a ‘M_register_gateway()’ is this the one to use in a plugin?

Hello there @vusis, I hope you’re well today!

What gateway are you trying to build? I’m asking because it may have already been created by another member.

2. Creating the gateway as a plugin

I’m afraid I don’t know the answer to that… However I have requested from the plugin developer to look at this thread. As soon as he’s available he will provide us with his insights.

Cheers,

Ari.

It’s a gateway for mygate.

@vusis unfortunately I’ve never seen that gateway before and I didn’t find anything from other members…

You could also try posting a new job at WPMU Jobs so that a developer can take a look at it.

Cheers,

Ari.

I’ve realized that after a transaction is processed, my function that handles the response works perfectly within the gateway. So I’ve made 1 step forward.

The function has two hooks: `do_action(‘membership_mygate_payment_success’:wink:

,$user_id,$sub_id` I obviously made changes from the paypal gateway.

The problem is, nothing seems to be catching this hook!! After this line is executed, nothing happens and i eventually end up in index.php (home page).

Please help with the order in which these actions are initiated so I can try and catch it.

Please note that the paypal gateway doesn’t work either – i get the same effect from it.

Thanks.

What have you got set up to catch the hook? You need to add an action to perform the processing after you fire the hook.

Have a look at the other gateways, and the gateway class that they extend and it will give you an idea of how they work.

I’ve already looked at them. I built this entire gateway by looking at how the others work…

They are quite simple in reality. They provide a number of methods to build a button to send a user to a gateway to pay, then add a listener hook for the hook fired by the payment return which checks the returned information and adds the user to the relevant subscription.

I’m not sure where you got “do_action(‘membership_mygate_payment_success’:wink:” from or which gateway you looked at, but the returning action would be:

add_action(‘membership_handle_payment_return_mygate’, ‘stuff to do’:wink:;

I am already handling the results successfully. The problems comes after the results are handled.

Instead of redirecting to a “Thank you page”, which I’ve set in the admin options, it redirects to the home page i.e. index.php. How do I get it to go to a specific after a transaction is processed (wither successfully or not)?

The gateway shouldn’t redirect, the confirmation is sent behind the scenes to the gateway which sets up the subscriptions. it has no interaction with the front of the site at all.

Or are you saying that your gateway doesn’t have an IPN style background API to fire and it uses a different method to confirm a payment.

It works exactly like paypal.. i.e. it opens a payment window and then returns when successfully processed.

I’m aware that the gateway processes the results in the background; however if you look at the paypal plugin it has the following code on line 900

do_action('membership_payment_subscr_signup', $user_id, $sub_id);

I’m under the assumption that one can use that hook to run another function that redirects to a “thank you” page of some sort. The trouble I’m having is that this hook doesn’t seem to work.

My question is, is there another way of achieving the same results?

It runs that hook in case any other plugin wants to hook in at that point of the process. The plugin doesn’t do anything with that hook, it provides it as a courtesy to other plugins / systems.

No, the processing is behind the scenes – server to server there is no browser to redirect to a thank you page. All the gateway does is provide the button, recieve the confirmation and set up the subscription. The rest of the membership plugin receives a click back from the payment form (see the return URL fields in the paypal gateway) to the Thank you page and then, assuming the gateway has received the background confirmation, prints the thank you page.

That is what I expected to happen. However, the trouble I’m having is that the thank you page is not printed. Instead, it just goes to the home page.

Perhaps there is a conflict in my theme… I’m not sure. Hence I tried to hook into the action I provided above (line 900) to build a custom process that deals with the thank you message.

However this too, is not working. For some reason my add_action() is not fired up. I’m not sure what’s going on….

Let me continue tinkering around…

What process does your gateway have for you to send it the url that you want it to return the user to? Paypal allows you to set the return url in a form field and that (the thank you page) is the url that the user is returned to when they click on the button.

There is no add_action hook you could run to set that page, so not sure what you mean here.

function my_function()

{

wp_redirect('another_page')

}

add_action('hook','my_function')

wouldn’t this work?`

Just tried to look at the docs for your gateway and they seem to be hidden away, or I couldn’t find any actual technical information on the site at all.

NO, the gateway is processing everything properly

The problem we’re dealing with is the last leg of the process; which is telling user that their transaction was successfully processed.

This is what the problem. is.

I think I understand what you’re saying…

Here is my Return url: http://sacbw.donebyexperts.com/paymentreturn/mygate

That simply goes to the home page after a transaction is successfully handled by the gateway; I want it to go to a thank you page… :..(

Yes, and as I keep writing :slight_smile:

What process does your gateway have for you to send it the url that you want it to return the user to? Paypal allows you to set the return url in a form field and that (the thank you page) is the url that the user is returned to when they click on the button.

You need to pass to the gateway the url of the thank you page so that it can return the user to it. It is usually called a “return url” or a “completed url” so the user clicks on the button, enters the payment information is given a “your payment is confirmed” message and a button to click on to the return to the site. You need to be able to set the url that button sends the user to.

How do you do that with your gateway?

No, that is your IPN url, your return url is the thank you page. They are different.

Again, look at the paypal gateway for an example. it sets the notification url as the paymentreturn url – that is the background process and sets the return url as the thank you page.

excellent I understand you now.

I thought that was the default URL that is handled at plugin level; wasn’t aware that it is gateway specific.

Give me a sec. Let me sort it out. Will get back to you in a minute.

one more thing;

if a transaction is not processed successfully, is there a page I can take a user to to retry?

I’m assuming that would be the same registration page where they initiated the transaction…

YOU ARE THE MAN!!

Thank you so much, my work with the gateway is pretty much over.

Now I just need to figure out how to make it a seperate plugin, and move it out of the membership folders…

Thanks.
