Integration method of php and paypal_PHP tutorial

I'm confused. I've been working on this function of paying with PayPal for 2 days recently and I haven't finished it yet. So depressed.
Make a note first and write down the parts that have been completed so that you don’t forget them later.
1 Register a SandBox account and create two virtual accounts. You can choose the one created automatically. A buyer, a seller. For testing during development.

2 Code for quick purchase. The link temporarily points to SandBox for testing during development. It will be changed to official later.

Copy code The code is as follows:

if(!defined("_f_afficherButtonPayPal"))
{ define("_f_afficherButtonPayPal ",1);
function afficherButtonPayPal($nbr_point,$montant)
{

echo" ";
echo "

//This was created just now The seller’s account

//The payment currency, I wrote Euro
// The total amount of quick payment
//The displayed paypal picture
< ;/form>

";
}
}

3 Send back the payment information. You should use IPN, but I haven’t figured it out yet. Keep up the good work

Supplementary information:
Learn from the reference document:
Paypal has specially developed Sandbox for developers to conduct development and testing
First go to https:/ /developer.paypal.com/ Register a development account,
Enter Sandbox to create a Paypal virtual account for testing (at least one Business and one Personal should be created),
This account registration method and Paypal process Likewise, the information can be fake, including bank account numbers and credit cards (in fact, Paypal Sandbox will automatically generate

some random numbers). Then activate the virtual account of Paypal Sandbox. Note that no matter what email address

you fill in when registering with Paypal Sandbox, any emails sent to the email address filled in the virtual account will be stored in the management interface of the development account. in the Email page (available on the navigation bar). Log in to the virtual Paypal environment of Sandbox

, and you also need to verify the bank of the virtual account. You can fill it in here casually, and then recharge the account through Add Funds (fill in as much as you want

as little as you want). Then, you need to activate the IPN option. In the Profile settings page of the Business account, click, then click the Edit button to open

IPN. If you are using a fixed IPN Handle, you can directly add Fill in the address.
Next, when we test, we should set the address of the Paypal interface to https://www.sandbox.paypal.com/cgi-bin/webscr
The final basic process is:
The user is in Select the product on our website, put it in the shopping cart, and then check and prepare to pay
The website generates a Paypal payment form based on the products in the shopping cart (which is also the Paypal interface address used to submit to the above IPN), including this transaction Some

information (I will find an opportunity to explain it next time). And generate an order record in your own database.
Paypal records these transaction information in Session

Users log in to Paypal with a Paypal account (Sandbox uses Sandbox’s virtual account), review the details, and click the Pay button
Paypal processes the transaction. If our There is no problem with the Paypal collection account in accepting the account (there is no special need to Accept), and the transaction

is completed, then Paypal will send an IPN and a reminder email.
Our IPN Handler receives the information and first checks it with Paypal. If the information is correct, then compares it with its own database. If

is correct, you can save the payment information and modify the order. state.
Then Paypal will display an interface to indicate that the transaction is completed. At this time, if the user clicks the "Return" button, Paypal will send the user back to the designated location on our website.
Our website welcomes users back, expresses gratitude to users, reminds them, gives order numbers, etc.
The last thing I need is a total price settlement, and I don’t need to connect with the online store. So it’s a lot simpler. Just generate the total price and put it into paypal and it’s basically done

Yes. If you have an online store, you still need to set a lot of parameters in paypal, which is quite troublesome.
