hey there, thanks for you patience and saving the code for the thread 🙂

        // Set API key 
        \Stripe\Stripe::setApiKey(STRIPE_API_KEY); 
         
        // Fetch the Checkout Session to display the JSON result on the success page 
        try { 
            $checkout_session = \Stripe\Checkout\Session::retrieve($session_id); 
        }catch(Exception $e) {  
            $api_error = $e->getMessage();  
        }

            // Retrieve the details of a PaymentIntent 
            try {

            } catch (\Stripe\Exception\ApiErrorException $e) {

                // Check whether the charge is successful 
                if($intent->status == 'succeeded'){ 
                    // Customer details 
                    $name = $customer->name; 
                    $email = $customer->email; 
                     
                    // Transaction details  
                    $transactionID = $intent->id; 
                    $paidAmount = $intent->amount; 
                    $paidAmount = ($paidAmount/100); 
                    $paidCurrency = $intent->currency; 
                    $paymentStatus = $intent->status;
                    $paymentItemNumber = $intent->description;
                     ```

#

      {
        "id": "li_1Ja3W2HhaDPa8eVPudjB6QM3",
        "object": "item",
        "adjustable_quantity": null,
        "description": "237",```

#

I need to get description from line_items

#

$paymentItemNumber = $intent->description;

#

this is returning nothing at all

#

                    $paidAmount = $intent->amount; 
                    $paidAmount = ($paidAmount/100); 
                    $paidCurrency = $intent->currency; 
                    $paymentStatus = $intent->status;```

#

these work and return datasets

zealous portal Sep 15, 2021, 9:17 PM

#

so, hang on

#

the line_items are on the session, not the payment intent

#

are you just trying to get them in the wrong place?

#

To get those session line items, you'll need to retrieve the session itself and use expansion:
https://stripe.com/docs/api/expanding_objects

Stripe API reference – Expanding Responses

Complete reference documentation for the Stripe API. Includes code snippets and examples for our Python, Java, PHP, Node.js, Go, Ruby, and .NET libraries.

#

where you've got $intent->description; would be getting the description form the payment intent, no the session line items

#

$session = \Stripe\Checkout\Session::retrieve('cs_test_123', [
     'expand' => ['line_items']
    ]);

#

you could also use this request ot expand the customer and payment intent and the same time, too 🙂

late tendon Sep 15, 2021, 9:36 PM

#

let me try that and see what I break next 😄

zealous portal Sep 15, 2021, 9:41 PM

#

keep in mind too that the line items are a list/array, so you'll need to traverse the index

#

item 0, item 1 ...etc

late tendon Sep 15, 2021, 9:49 PM

#

this applies to retrieving metadata as well?

zealous portal Sep 15, 2021, 9:50 PM

#

metadata should be included by default for each object

late tendon Sep 16, 2021, 12:27 AM

#

All I want to do is pass an identifier so I know what the product id is after the checkout is complete

#

                'price_data' => [ 
                    'product_data' => [ 
                        'name' => $productName, 
                        'metadata' => [ 
                            'pro_id' => $productId
                        ] 
                    ], ```

#

seems it's a line_item too

mortal flume Sep 16, 2021, 12:30 AM

#

Hello! The code snippet above looks like it's from creation of a Checkout Session where you're specifying new Product data (which will create a new Product in Stripe every time). Can you tell me more about your use case/what you're using Checkout to charge people for?

late tendon Sep 16, 2021, 12:32 AM

#

yes

#

one moment

#

https://www.codexworld.com/stripe-checkout-payment-gateway-integration-php/ I largely followed this implementation

CodexWorld

Stripe Checkout Integration in PHP - CodexWorld

Stripe Checkout in PHP - Stripe checkout payment gateway integration in PHP. Example code to integrate Stripe checkout to accept credit or debit card payment using Stripe PHP Library and JavaScript API.

#

but the issue is all the price\item is static

#

basically they can goto the page and decide how much for a particular "item"

mortal flume Sep 16, 2021, 12:34 AM

#

So you need dynamic amounts defined by the customer for your integration?

late tendon Sep 16, 2021, 12:35 AM

#

yes i'm able to dynamically set the price the problem is I have no idea what item it is for

#

without returning a product identifier after checkout

mortal flume Sep 16, 2021, 12:35 AM

#

I recommend you add the product identifier to the Checkout Session as metadata.

late tendon Sep 16, 2021, 12:37 AM

#

it already is I see it in the stripe test data

#

but I need to take further action once the checkout is complete

mortal flume Sep 16, 2021, 12:37 AM

#

Can you give me the ID of a Checkout Session with the metadata set so I can see what you're seeing? It's the ID that starts with cs_

late tendon Sep 16, 2021, 12:37 AM

#

sure one moment

#

cs_test_a1B6JCzaPBGd5pMsciIfFN8eWSJcgYxUu0dgzJjC4vijyN9ntOBwXLQgDD

mortal flume Sep 16, 2021, 12:41 AM

#

In Stripe a Product has one or more Prices, and you use Checkout to charge people for one or more of those Prices. You can create a Checkout Session with Product and Price data to create Products and Prices on the fly (for dynamic amounts), but the Checkout Session's line items will only show the Prices, not the Products they belong to.

Thinking about it more, if you're selling multiple Products/Prices in a single Checkout Session, you would probably want to add the Product ID you need as metadata on the Price, not the Product. That way you can access it directly on the Checkout Session with line_items expanded: https://stripe.com/docs/api/checkout/sessions/object#checkout_session_object-line_items-data-price-metadata

#

Yeah, in that Checkout Session you're setting the metadata on the Product, not the Price. If you change it so you're setting it on the Price I think it will work the way you want.

#

Wait a second... can you set metadata on the Price when creating a Checkout Session...

#

Oh, wow, you can't.

#

Hm, okay.

#

Going to flag that internally.

#

Okay, so scratch setting metadata on the Price, you should probably set it on the Checkout Session itself: https://stripe.com/docs/api/checkout/sessions/create#create_checkout_session-metadata

late tendon Sep 16, 2021, 12:45 AM

#

      {
        "id": "li_1Ja3W2HhaDPa8eVPudjB6QM3",
        "object": "item",
        "adjustable_quantity": null,
        "description": "237",
        "discount_amounts": [
        ],```

#

seems I set it on the description successfully

#

"description": "237", <===

mortal flume Sep 16, 2021, 12:46 AM

#

The description is visible to the Customer. If that's okay with you that will work too.

late tendon Sep 16, 2021, 12:46 AM

#

sure it doesn't bother me at all

#

it's just a product id

#

long as they can't change it 😄

mortal flume Sep 16, 2021, 12:47 AM

#

Nope, they can't change it! 🙂

late tendon Sep 16, 2021, 12:47 AM

#

that's one thing I wasn't sure about pre-purchase and wanted to ask

#

because it's using javascript it seems

mortal flume Sep 16, 2021, 12:47 AM

#

What is?

late tendon Sep 16, 2021, 12:47 AM

#

wasn't sure if they could manipulate the request

mortal flume Sep 16, 2021, 12:48 AM

#

Your PHP code is creating the Checkout Session and setting the description, right?

late tendon Sep 16, 2021, 12:49 AM

#

yes and handling the price to make sure they don't do anything undesirable

#

but I wasn't sure if it was just echo'd and handled by stripe js

#

where they could set any product id paired with that price

mortal flume Sep 16, 2021, 12:50 AM

#

No, they can't modify the description on the Checkout Session object in Stripe. They could modify the Checkout page to display something different client-side, but that change wouldn't impact anything server side.

late tendon Sep 16, 2021, 12:50 AM

#

phew good thanks

#

sorry for my newbie understanding of things

mortal flume Sep 16, 2021, 12:51 AM

#

No worries at all, we're here to help!

late tendon Sep 16, 2021, 12:52 AM

#

so after the checkout I want to fetch this description as seen #887792505989496852 message

#

$paymentItemNumber = $intent->description;

#

didn't seem to work

#

which brings me full circle

mortal flume Sep 16, 2021, 12:53 AM

#

$intent is the Payment Intent, right?

#

One sec, let me type up some code...

late tendon Sep 16, 2021, 12:55 AM

#

https://www.codexworld.com/stripe-checkout-payment-gateway-integration-php/ yeah it looks like this abomination see success.php

CodexWorld

Stripe Checkout Integration in PHP - CodexWorld

#

i'll have to look at it closely who knows how secure it is I just want a test that works

mortal flume Sep 16, 2021, 12:55 AM

#

Try this:

$checkout_session = \Stripe\Checkout\Session::retrieve([
    'id' => $session_id,
    'expand' => [
        'line_items'
    ],
]);

$first_description = $checkout_session->line_items->data[0]->description;

#

You need to retrieve the Checkout Session with line_items expanded and then traverse the object down to the description.

#

You would change data[0] to data[1] for the second description, data[2] for the third, etc.

#

Or you can loop over data to handle them all.

#

Does that make sense?

late tendon Sep 16, 2021, 12:57 AM

#

yes let me see if that works thanks

#

are you guy the in the videos on youtube? 😄

#

your avatar looks familiar hah

mortal flume Sep 16, 2021, 12:57 AM

#

No, I'm not. 🙂

#

I know him though!

late tendon Sep 16, 2021, 12:57 AM

#

hah my mistake

#

thanks I'll give this a shot 😄

#

phew that works thank you so much

mortal flume Sep 16, 2021, 1:01 AM

#

Awesome!

late tendon Sep 16, 2021, 1:01 AM

#

i know you're doing your job but a working code example geez

#

best support I've ever experienced hah

mortal flume Sep 16, 2021, 1:01 AM

#

That's great to hear, thank you!

late tendon Sep 16, 2021, 1:02 AM

#

thanks for helping a newbie and not talking down to me

#

night

mortal flume Sep 16, 2021, 1:02 AM

#

Anytime! Have a great night!
