in this video you will learn how to accept PayPal payments on your website

and then with the help of instant payment notification how to

automatically send everything to the customer so let's do it

hey what's up guys Senaid here from codingpassiveincome.com the place where I

help others to become a web developer much easier and fast and then they will

do it on they own so if that's something that interests you consider subscribing

so before we actually start writing any code I want to explain you the basics

that you need to understand for this tutorial so that you have a visual

representation of what is going to happen so we are going to create a one

simple website let's say like this and then here we will like to sell something

let's say a wordpress plugin or something and then we will have some

futures of our plugin here and we will add here a PayPal button so now once the

person press this button we will resurrect him to the PayPal website and

here he will be able to purchase our product so now if he decide to press a

cancel button we will resurrect him back to this page but if he successfully

purchase this product we will resurrect him to some thank-you page like this and

they will say he thank you okay but now what will happen in the background the

PayPal let's say here it's paper the PayPal will send an instant payment

notification to our server so let's say we will have here one file let's say

callback file and then once the PayPal send an instant payment notification we

will inside this file accept all those information we will verify if he really

purchased this product because in most cases there will be a people that will

try to scam him and then if everything is okay we will send to this person an

email that contains all the details and about their purchase and also the voter

flag in the debugged so I hope so that this is

very simple process and I will show you that the code is much simpler than this

explanation so let me now show you how to write the code so now I'm here at my

PHPstorm I have created a new project in that project I have one folder

attachment and there's some zip archive that I will send to the customers and

then I have an empty index.php and listener.php or we can name it

callback dot PHP whatever you like so now first let's quickly design some

basic pricing page I will say here pricing page and now I'm going to

include the booster so I'll say getbootstrap.com and I'll go to download ok and

down below I will just get CDN link for the CSS and I will include it just

before closing head tag so in here I will have one class container and in

that container of course you are going to have one row and then inside this row

I will have just one column so let's say col-md-6

and I will set offset to the tree so that from the boat side we have same

padding and on that way we have everything in the center ok cool

so now inside this column I'm going just to create something that is the latest

in the booster for and it is card so we will say their class card and then we

will have card-header and here we will have card-block which is basically the

body of our card so maybe in this book I will say we will have card

title and then I would say it is WordPress plugin and then I will just

specify some like pewters so let's say this is a list group and then I will

have different list group items so maybe let's say future one let's say you have

multiple of those ok and maybe up here I will say okay I want <h3> and this

will be let's say does the price so let's say 67$ okay so I

have just saved this and let's see what I got

so just upload everything because for us in order to test the PayPal gateway IPN

we will need to have it on the live server and we are not able to test it on

the local host anyway so it is okay

and here is the basic design that they have

so maybe we can write some CSS here at the head so I would say style text/css

let's say our container will be margin-top let's say whole pixels and

let's see here we'll have or maybe in the row I will say line to the center or

maybe to be better received just fine content to the center and then let's say

for the please group item I will say that I will have padding of five pixels

and maybe let's remove I think we have the border yep

so let's remove this border shall see for the ratio pixels and let's see what

will happened

okay so maybe we can for God here say text center and then maybe I'll go to

say it like span I'll define some class currency and <h3> will be class price

so now let's write let's say that the price font size I will set set to pixels

I want something big

okay and then for the currency I want font size are very small let's say 25

pixels I mean small in comparison with the price then I will set the position

to the relative and maybe lets its top like -30 is this

okay cool so this is looking good maybe we should

just put here everything in here the center and then maybe on I will set card

to the let's see 300 pixels and then card horror let's say transition okay

transform I will set scale to the 1.05 and then maybe let's set transition to

the let's see this should be the time and then he is in out will be how we are

going to do it and I would delete this okay so let's say see what we have now

okay so now it is looking good and if we do okay this creates a really nice

effect here and that's it so now the next thing that we need to do

for this pricing page is we really need to add Buy Now button from the Pay Pal

and now in order to do that we will need to log in to our PayPal account and then

once you are logged in you just need to go to the tools and then to the all

tools and you should get a similar design like I have I think that it will

depend on the type of the account that you have on the paper but something

similar will be there and then you will just need to find PayPal buttons click

there

and then I will go to the create new button and now here we have a different

types of the button for this one I will choose by now okay

here for the item name I will say water spoiling and then for the item ID I will

say again what this plugin so I will just use this to identify that it is

this one product because maybe on this pricing page you will have a lot of

different products that you want to sell so the price for this one will be 67 I

don't need anything else then here I will remove this option and

then here in the Advanced section I don't want to add customer to change all

the quantities sorry I don't want any special instruction shipping enters we

don't need and then here are the things that I have been talking about so for

the cancel if I will press cancel I want to resurrect them again to the

sales page to the pricing page okay and now when they finish checkout we will

reject them to the some thank-you page we don't have it at the moment and then

here is an important thing as you can see if we want that paypal send an

instant payment notification to our website we will need to add advanced

variables and then we need to say notify URL okay equal and then to specify the

link to the file where it will send all the details so I will just say Western I

think that is the name of the file that we used second yes this so little dot

PHP okay and that's it it does go to create

but so now here you will get the code that is ready to be just pasted in your

website and here's the design as you can see this one is encrypted and you can

use that one or if you click remove code protection you will get something that

is much readable and you will if anytime you want you will be able to quickly

modify this code but probably I will always suggest to you to just use

protected version because that way it is much harder to try to scam it also there

is an option to use an email and all you need to do is just to get this link here

and then just create a normal link in your HTML document but I will just use

this protected version I will just copy and then I'm going to paste here under

this list so let's say I will put new twin brake lines and have just pasted

everything in I will save it now let's see what will happen on our sales page

so if we refresh the pinenut by now but that is there and be quick we will be

redirected to purchase this okay and if I now decide to cancel I will be

redirected to the pricing page again so now this is all that we need to setup in

the part what the customer or the Vista to our website will see but now the

problem is to set up instant payment notification and what will happen once

the customer purchase your product so in order to do that we will need to go to

the developer dot paypal calm and you have to notice that

their vision s after the developer so it's not developers its developer and

then I will go to load into dashboard and here again you can just use your

normal login details from the paper okay we are loaded in and now what is

important for us here to use all I want is IP and simulator basically with this

I beam simulator we are able to just to send to simulate the purchase and on

that way could make a code on our back-end and verify that everything will

work just as we want so first thing is ID Panhandle URL so that one I will copy

here and then how does sale here Lister the problem is that you are not able to

just test it if you don't have this file so just make sure that you have one

uploaded and that's it and the problem is that most of the time if you only

have the file this IP and handle your out will always work so you just keep

that in mind so transaction type let's say that we

will have a asset okay and then here are the payment information that you can set

up so that you can make a test so let's say first times will be instant payment

date okay payment status let's say completed a trash fire status first name

last name for email or ID address name address country country code those are

all the things basic before the customer and earlier I never change any of those

because it's not important now here for the business and

receiver email and ID I usually write here something like let's say calling as

income and then here I want to use an email that will actually receive all the

payments so I want to test that okay and then for the item name you just need to

make sure that this is the one that you have been using on the PayPal and we

created by now button and then item number sorry guys this should here and

then item a miss board press ok and quantity shipping tax we

really don't need any of those we can just delete if you want to and then

currency fee that's not that much report and gross let's say this is our price

that we want to have you can delete this one Sumter section ID not 5 version etc

etcetera we really don't need any of those things okay cool and now if we hit

send ipn the word thing is that you will always need to scroll up and here's what

the IP Anderson and the handshake was verified it is okay but the problem is

that we don't have set up any listener so far so let's create one so I will

just open PHP thanks doesn't mean a little bit and now the

first thing that I want to track if a server request method equally put post

or maybe different than post I want just to redirect person to them index.php so

all I'm doing here is basically if someone has found that we have less than

a dot PHP file we just want to verify that there is some post executing on

this page and if it there isn't that we want just to redirect that person to the

our pricing page okay so now here probably we will receive the details

from the paper just here is I've been simulator and if we open here you can

read a lot more about this IPIN simulator and all the things that we

will need to know okay so basically we need to verify all the information that

we have received in this speed derive directly on the paper and if there isn't

a verification from the paypal that means that probably someone is trying to

scam us so for that reason I'm just going to write here I will use cool so

I'll say call handler equal called init okay and now here I will say sorry cool

set up

sequel opt and then URL in the URL on which we are going to execute this code

is here so I will just copy and paste here

now the next thing that you need to set up is

we'll return transfer I will set to the one then let me just duplicate this then

the next thing is s somewhere if I host I will set the 0 then we have verify

here how does set the zero again then I will

say just because implicit so I'll stay here pull off let's say post I will set

it to the one and now post files ok and here I'm going to say command e go

notify and voila day so this is something that is required by the paper

so we need to include this command that we want to notify and validate this

information that we have received here and then I will obtained here hurting

from the post okay and after that I think that we have set everything and I

am going just to execute this ball handler and of course I am going to

close it okay so basically what I have done here I

have set up some URL for the call I have decided that I want to return transfer

from the paypal husband in it I don't to verify anything related to them SSL and

then I have decided to we are going to make a post request and then here are

the informations that we are making through this post and of course here we

need to execute so let's say just I want to

with everything to them let's say test 50 and then response I want to see what

will be returned by PayPal once we try to verify okay

and I will just upload listener

okay and now let's try again this simulator I will say sent IP n okay it's

done and let's try here now test the Eckstein and here is what is returned by

paper so I'm not sure what this says that there is no transactions that's

weird

so let's check our code the code is looking good but it was that I have

forgot here include a person okay so let's see and try again

so I'll hit Send IPN again okay crash okay

and now it says that the data has been verified and basically this is always

what you are looking for when you are verifying is actually the payment

happened on the PayPal side so if this response equal verified that means that

the purchase is surely there and everything is looking good so for that

reason I'll just say here if response Iko Iko verified okay and usually what I

love to check here is basically who is the receiver of this transaction because

someone can try to purchase to his own email so here at the top we have

receiver email and basically that is what you are looking for so I'll say if

response equal verified and post receiver email = email that you

have specified here okay I did and on this way we are actually sure that there

isn't any problem with this email so we are actually the one who received the

payment and now we can say here else we can maybe write some error to the error

log or maybe we can send an email to ourself and basically to save everything

from this post does to know what is happening behind but I'm not

to do this inside this tutorial because we just want to make sure that the

payment has happened it's verified we are the ones that received an email and

also now we are going to check the price of our product so the price we will get

so maybe let me show you first what what are all the information that we have got

inside in this IPN so I will just say like for each let's say handle equal

open and then I will use just again same file I will use more the bright and then

here I will say foreach post as key

value I will write it to them this handle and let's say to be key

value and then on your Y and here I will just close it this handle okay like this

so let me now just quickly upload and show you what are the information that

we are going to get down I will hit Send IP n okay and let's not take a look so

here we go so basically we have keys payment type payment date payment status

address that aspire status first name last name fire email address name and

all other informations business receiver email this is one important item number

and item name quantity we have MC gross which is basically how much money

someone paid of course also information like currency fee etc etc but now for us

basically to verify this and be able to send to this customer an email I will

just get a first name last name fire email and of course you will need to get

price and item maybe number so let's do it

so I will see customer name is basically the first name and then separate by so I

will say last name okay now price we said is in the MC cross I guess we can

always make sure that yeah it's a super us okay we want also to check the

currency it is not the same if someone is paying in something else

see currency okay and then we have item so let's say boss item number

okay we will also need customer email

customer email is it's fired so that you can send an email the plugin that he

bought and I guess this is all that you need to have so far yeah I think it is

maybe we can track the penis that's so payment that's his boss

cool so now we want to make sure let's say I will dust no like this so those

are the things later the purchase and those two are to the customer so here I

want to see if item equal WordPress plugin

and currency equal USD and I think it is USD let's put picture yeah capital

letters okay and if payment status equal confirmed and of course the last English

price and price equally both 67 we will execute this part of the code here which

means that basically we are just going to send an email to this customer so

what else we can do is to use those information and if you are selling

membership access or anything else to create a new account in the database and

then send a login details to that person but for the purpose of this tutorial

that is not that much important so let me just now quickly save file put

contents okay now let's see-oh verify so this is

just to make sure that we did everything correctly

because we do not have any any other way on how to test this okay I'll try to

send ipn again okay cool - and we didn't get anything so there

has to be some mistake so maybe let's say else

with condensed

dude

and then he I'll see the top and I want just make sure the date that equal then

I will just say price okay and then currency and then item I want to make

sure that we can identify what is the problem so let's see

okay I will send idea again

okay so I think the problem is with the status I said here confirmed and

basically it is completed okay so let's try to test again so that is why this IP

and simulator is so important because there are hundreds of places where you

can make small mistake and your IP n won't work so now it says all verified

okay it's amazing I can now just delete this okay and now inside here if

everything is verified I would love just to send to our customer an email that

will contain attachment that he booked which is basically what was plugging and

for that purpose I'm going to us to use PHP mailer of course shall go to the

Google and say it be mail at don't go here then I'll go to the phone or

download and I'll just put it down okay I'm going to save it to our folder and

let me just fine

here so extract everything here I will delete this archive

maybe I should rename this okay and then I will just delete everything except

source then I would the source get everything move here and then delete

this I mean this is just the way that I love to organize the files okay cool so

now first thing that we need to do is basically here at the top will need to

use PHP mailer namespace so see use PHP mailer so this is usually the namespace

of the PHP mailer and you can find that in the documentation github okay and

then I'm just going to include so yeah I would say PHP mailer and then I will use

PHP mailer for us and I'm going to get exceptions okay I don't I think that we

don't need any of the others for the purpose of this video tutorial so here

I'm just going to create a new object so seen u8p mailer

okay and here for this object we need to set so same mail and then I will say set

from so this is who is sending an email so does a sales@codingpassiveincome.com

comment and then the name I'll say CPI's feels okay then I want to set okay we

can add attachment which is the path is attachment so just quickly attachment

and then the name is WordPress plugin so I'll say here WordPress plug-in

that's it tako then you can specify the name for it I will just say WordPress

plugin okay now mail is add address which is where we are sending an email

so that person is theirs customer email and then the name is we have it okay

cool so now I will say mail is HTML I'll say true so I am going a little bit

faster over those settings for the PHP mailer and for those of you that really

don't understand this part you can find a lot of different tutorials on my

channel related to creating content food and sending an email using PHP mailer

and then I will set subject so I'll say

thank you maybe your purchase details okay and then body okay yes shall say

maybe hi - no one's thank you for purchase and attachment you will find my

amazing wordpress - my regards maybe whatever I mean this is not that much

important and then here I would say mail send and that's it

so let's verify it once again we have said who is sending you said an

attachment who is and where we are sending we said that it is HTML subject

body and pretty much that's it so now let's quickly just upload everything

fresh

and let's make a test but first I want here to change who is the buyer so I'll

set by email to one of mine shall see hello and let's see any calm calm and

then I will just say send IPN

so let's now see and I get any email maybe we have made some mistake so yep

here is the latest one it says your purchase details CPI sales and if I

click here it says hi thank you for purchase blah blah and in the attachment

there is water spot and yeah that's it now it is everything working just as it

should so guys I hope that you have enjoyed this video if you do please like
