Hey @hallow pier you control the creation of the Session so yes, you can create a Price for the right amount and pass that

hallow pier Oct 12, 2022, 12:53 AM

#

The price is already set

#

I want to modify the default value they see when they get redirected to the checkout so they can pay right away, or change the amount at checkout if they change their mind.

#

The documentation only says I can change the quantity?

upper peak Oct 12, 2022, 12:55 AM

#

I don't understand what you call the default value and what price is already set

#

you can't change a Session. You need to create the Session after they choose how much to pay

hallow pier Oct 12, 2022, 12:56 AM

#

This is where they pick the amount they want to pay, but the product it uses is allowing for them to change the amount to pay only in the checkout itself

upper peak Oct 12, 2022, 12:57 AM

#

sure but that's just your UI

#

create the Session after they click on the Donate

hallow pier Oct 12, 2022, 12:57 AM

#

#

It just sends me here, I cannot figure out how to change what it shows there, while creating the session

upper peak Oct 12, 2022, 12:57 AM

#

I'm sorry, you still only give half of the info I'm after

hallow pier Oct 12, 2022, 12:58 AM

#

hold on, let me get it from the dashboard.

upper peak Oct 12, 2022, 12:58 AM

#

Are you using PaymentLinks?

hallow pier Oct 12, 2022, 12:58 AM

#

No

#

But the product I use lets users change the amount to pay within the checkout

#

And I am trying to modify the default amount before it goes to checkout

#

https://stripe.com/docs/payments/checkout/pay-what-you-want used this

upper peak Oct 12, 2022, 12:59 AM

#

yeah that's impossible

hallow pier Oct 12, 2022, 1:00 AM

#

#

So I cannot allow them to use a slider before they get to the checkout to modify it?

upper peak Oct 12, 2022, 1:00 AM

#

correct you can't

#

not unless you create a separate Price for this and set a different preset each time, which isn't really worth the trouble

hallow pier Oct 12, 2022, 1:01 AM

#

Yes I can see why that would be unwise, I could maybe get around it using quantities on a £1 price and avoid this price entirely?

upper peak Oct 12, 2022, 1:02 AM

#

you could, I wouldn't. I'd remove the slider entirely and let them change the amount on Checkout

hallow pier Oct 12, 2022, 1:02 AM

#

Ok I just wanted to make the UI look better for them and match how other services that take donations work.

#

Thanks for your help.

upper peak Oct 12, 2022, 1:03 AM

#

sure!

This has been a live option for some time because it didnt error before, but I am not getting errors for this and not the subscriptions.

#

@steady star

steady star Oct 12, 2022, 1:37 AM

#

The error says Undefined constant "console" in /donate/return.php:126 , did you check you code in line 126?

hallow pier Oct 12, 2022, 1:38 AM

#

The issue is before that

#

The warnings are what I am concerned about, console is for troubleshooting.

#

It isnt on the live server that my customer pointed the issue out in

steady star Oct 12, 2022, 1:39 AM

#

Do you have the code? we can look at it together.

steady star Oct 12, 2022, 1:44 AM

#

Hmm, I don't think console.log is available in PHP.

hallow pier Oct 12, 2022, 1:45 AM

#

I think I messed that up, but its not relevant to the code

#

evt_1Lrty3EOJsqRXL0R2SfGd7x8

#

This is the payment that triggers all the errors

steady star Oct 12, 2022, 1:47 AM

#

Did the error occur in webhook handling? do you have the relevant code?

hallow pier Oct 12, 2022, 1:48 AM

#

No the webhook was errored for the live endpoint being used not the test one

#

The error is to do with retrieving the data from the checkout session in the code I send

hallow pier Oct 12, 2022, 1:48 AM

#

hallow pier ```html <?php ini_set('display_errors', 1); ini_set('display_startup_err...

Something here about getting the data from payment intent is the issue

steady star Oct 12, 2022, 1:49 AM

#

Can you send me the relevant error message and the line that causes the error?

hallow pier Oct 12, 2022, 1:50 AM

#

Warning: Attempt to read property "payment_method_details" on array in /home/u201085483/domains/jconet.co.uk/public_html/donate/return.php on line 72

#

steady star Oct 12, 2022, 1:51 AM

#

These are warnings, what's the error?

hallow pier Oct 12, 2022, 1:51 AM

#

That is the error

#

It is meant to update the default payment method to the payment method used if one isnt set

#

It isn't retrieving the payment intent from the checkout session

#

How do I hide the line 72 error as i need it to show the payment method details, but it says attempt to read value on array

steady star Oct 12, 2022, 1:55 AM

#

Again these are warnings, not errors. The compiler tells you that certain property could be null, so you should do a null check before attempting to read the property.

hallow pier Oct 12, 2022, 1:56 AM

#

ah ok thanks.

#

i guess isset() then?

steady star Oct 12, 2022, 1:57 AM

#

Yes you are use this function

hallow pier Oct 12, 2022, 1:59 AM

#

This will get rid of the warning?

steady star Oct 12, 2022, 2:00 AM

#

You need to test out by yourself.

hallow pier Oct 12, 2022, 2:00 AM

#

Yep worked, thanks.
