4.4 PayPal Settings in PHP

Let's start investigating the '05Demo' (download demo 05). The '05Demo' has three new folders from it's predecessor.
We will talk here about the folders 'SecretDownloads' and 'PayPal'.
SecretDownloads contains random sub folders and at the last one contain our digital products. As you can understand it is important that the sub folders must be renamed and add even more random sub folders. Here is proposed only an idea of how that folder should look. You must change / rename the all sub folders and even the name of the SecretDownloads folder. It is important that you personalize this right now. If you paid attention at the last sub folder there are the digital products and a file named GetAbsoluteDirectory.php, just leave that intact. Keep in mind that your url length should be at maximum 255 characters.
Example :
www.mysite.com/SecretDownloads/123456789/123456789/123456789/
has a length of 61 characters. The SecretDownloads must be Chmod 755 at least. This means : read and execute access for everyone and also write access for the owner of the file. These details will be explained at the chapter 'Going DEMO'. Once you have personalized your secret path it is time to set up your PayPal settings. Open the PayPal folder, there you will find the 'settings.php' file and the 'Code' folder. The code folder you can leave it contains the PHP code which does the steps 3 and 5 described before. The 'settings.php' file once configured you can leave it as is. Let's take a closer look of that file by opening it with notepad++

<?php
//General settings. You have to set them only once.

//1. The page title of the download page
$SettingsDownload['TitlePage'] = 
'Download your digital product.';
//2. The secret download directory. 
This directory must be writeable ! The 
SettingsDownload value can be found with 
two methods: 
////a) Relative path : With '../../' you are at the 
ROOT of the '05Demo' directory. Now add the relative 
path from ROOT to SECRETPATH
////b) Absolute path : Put the 
'GetAbsoluteDirectory.php' to the SECRETPATH and 
access it with a browser. 
Get the value and DELETE GetAbsoluteDirectory.php
$SettingsDownload['file_path'] = 
'../../SecretDownloads/556622/abggretttt77/jjMMn5
4VrtP/xyz321/';
//3. The referer site link.
$SettingsDownload['referer_url'] = 
'www.mysite.com/05Demo/PayPal/Code/pdthtml.php';
//4. Enable download counter 
(recommended value: True)
$SettingsDownload['enable_download_counter'] = True;
//5. How many download attempts has one buyer.
$SettingsDownload['Max_downloads'] = 2;
//6. Enable Logs (reccommended value: True)
$SettingsDownload['enable_log'] = True;
//7. Specify the filename of the logs
$SettingsDownload['log_file_name'] = 'downloads.log';

////////////////////////////////////
////MODIFY the PayPal Settings//// 
///////////////////////////////////

//1. The auth_token of the real account seller.
$SettingsPayPal['auth_token_real'] = 
'XXXXXXXXXXXXXXXXXXXXX'; 
//2. True means TEST MODE SANDBOX - 
False means REAL MODE 
$SettingsPayPal['sandbox_mode'] = True; 
//3. The auth_token of the sandbox account seller.
$SettingsPayPal['auth_token_sandbox'] = 
'XXXXXXXXXXXXXXXXXXXXXX';
//4. The Failed Transaction Message 
$SettingsPayPal['completely_failed_message'] = 
'Your transaction has been failed.

PayPal settings file

---

We can clearly see two sections of settings. The Download settings and the PayPal settings. From the download settings we have :

• The title of the download page.
If you like the title leave it as is.
• The secret path.
Make sure to change it with your personalized path.
• The referer site link.
For the needs of our demo this should be something like this : www.yoursite.com/05Demo/PayPal/Code/pdthtml.php
but generally should be :
www.yoursite.com/PayPal/Code/pdthtml.php
• Enable download counter
Leave it as is (recommended value: True)
• How many download attempts has one buyer.
Leave it as is for now.
• Enable Logs
The default setting is good for you. (recommended value: True)
• Specify the filename of the logs
Leave it as is.

From the PayPal settings we have :

• The auth_token of the real account seller
We will talk about this later in this book right now leave it as is.
• The sanbox mode
Leave it to true for now. This means we are in TEST mode.
• The auth_token of the sandbox account seller.
We will talk about this later in this book right now leave it as is.
• The Failed Transaction Message
This you can customize it right now if you want.

As you can see, the download settings can be and should be set right now, the same thing is not true for the PayPal settings since the only value that we can define is the 'Failed Transaction Message'.
Please note that all the other PayPal values will be set later.
