Form defaults / parameters

[apps@ascension.oneParticipant]

Hi guys,

I have already read that it is currently not possible to pre-populate fields with custom or default values in the payment form … which is what is most needed on our end to have a more seamless business logic though. Especially predefine name & email, but also eg. a suggested donation value.

It seems though like there are plans for that? Do you guys have any roadmap? I guess all that could even be a form-defaults action hook for setting default values (which could be safer than just via get params).

Thanks!

We should be able to add filter hooks for this. I will look into this.

Hi.

You can change customer name and donation amount by hooking to asp-button-output-data-ready filter.

Here’s quick example how to change customer name: https://github.com/Arsenal21/stripe-payments-enhancements/blob/master/asp-prefill-customer-name-and-email/asp-prefill-customer-name-and-email.php

You can change donation amount like this:

$data['item_price'] = 10000; //amount should be in cents

Excellent, Alexander – this is basically exactly what I was looking for. Cheers guys!

Hey alexanderfoxc,

I have a question regarding prefilling the user data using the GET method. Before the payment, I make the user fill out a form with email, phone and name info. On the payment screen, I don’t want them to reenter their name and email. So I want to send the name and email info like “site.com/payment-screen?name=John&email=john@site.com”

I added a few lines of code to the code you shared earlier to prefill the name and email with the GET data.

// Get the URL parameters assign variables
if (isset($_GET['NAME'])) {
    $s_name = $_GET['NAME'];
} else {
	$s_name = "failed to get post parameter";
}
if (isset($_GET['EMAIL'])) {
    $s_email = $_GET['EMAIL'];
} else {
	$s_email = "failed to get post parameter";
}

and changed the code you shared to:

public function handle_data_ready( $data ) {
		$data['customer_email'] = $s_email;
		$data['customer_name']  = $s_name;
		return $data;
	}

But it’s not working. I didn’t have high hopes anyways with my little knowledge of PHP. But I was wondering if you had a solution for this.

My next solution might be to try to auto-register the user after filling out the form so the name and email get filled from user info.

Thank you!
