How to integrate paypal by php

Paypal is the most used online payment gateway in the world. It is secured for both buyer and seller. So, for online transaction both buyers and sellers like to use it. But how PayPal gateway is integrated in web? A lot of tutorials are available in online. I will discuss here about the easiest way to integrate.

I will use PHP language for integrate it.

First Step: Create a Form

Keep the information of product items that you want to sell in a form. It is just a html form tag (<form>). Below is an example of a form:

<form action="https://www.paypal.com/cgi-bin/webscr" method="POST">

<input type="hidden" name="cmd" value="_xclick" />
<input type="hidden" name="business" value="nurulsnit@gmail.com">
<input type="hidden" name="item_name" id="item_name" value="My Product" />           
<input type="hidden" name="currency_code" value="USD" />
<input type="hidden" name="amount" value="10" />

<input type="submit" value="Buy Now"  />

</form>

Explanation of the above code:
Form action = https://www.paypal.com/cgi-bin/webscr. It is live paypal link. If you want to test the payment you can use sandbox paypal link. ( Sandbox is a test mode of paypal, in next post i will discuss about sandbox ).

Sandbox form action will be = https://www.sandbox.paypal.com/cgi-bin/webscr

<input type="hidden" name="cmd" value="_xclick" />, it is an essential variable for paypal transaction. This is a hidden type variable which name is cmd and value = _xclick.

business variable contains your paypal business account mail address. In this paypal account the payment will send. It is the seller paypal id.
item_name is the product name which is selling or purchasing.
currency_code is the currency name of transaction.
amount is the product price amount.
        

Date format change by php code

For software development we need different types of date format.

We can do it by a simple line of code. There is an example below:
$cdate = '2013-10-25';  // Y-m-d format
$rdate = date("d-m-Y",strtotime($cdate));  // d-m-Y format
echo $rdate;
I think it will help you.

Take difinite number of word from a string

The following function is for to take a definite number of words from an string:

function take_definite_number_word( $words = 10)
{
     $wordCount = count(explode("",$item->description));      // count by space
     if ($wordCount<$words)
    {
            $adjustedText = $item->description;
     }
     else
    {
          $adjustedText = implode(" ", array_slice(explode(" ",$item->description), 0, $words));
    }
}

then close the php tag by ?>

 This is my firt line of code!

so the code is here:

<?php

  echo "This is my firt line of code!";

?>

how redirect by .htaccess with a link of space %20

Redirect by .htaccess is easy for a server.
If you want to redirect a link then put the .htaccess file in root folder of the server.
Then put the following of code in .htaccess file.

Redirect 301 old_link.html  new_link.html

the above is normal rule. but if you have space in the old link (not _ ) then it makes problem.

then add the following code after RewriteEngine On

RewriteRule ^/?tag/(.*)\ (.*)$ /tag/$1-$2   [L,R=301]

then put the redirect condition suppose:

Redirect 301 '/codebooks/Malawi Geocoded Aid Codebook.pdf' http://aiddata.org/weceem_uploads/_ROOT/File/geocoding/UCDP_AidData_Codebook_Published.pdf

the Malawi Geocoded Aid Codebook.pdf is in single cote and this link has %20 or space

it was :  /Malawi%20Geocoded%20Aid%20Codebook.pdf 


i have become success by following above rule.

how on allow_url_fope in server

Some times you need to on allow_url_fopen in server. then you can try by the following two ways:

      1.   Create a .htaccess file and keep it to root folder ( sometimes it may need to place it one step back folder of the root) and paste this code there.
php_value allow_url_fopen On

     2.   Create a php.ini file (for update srver php5.ini) and keep it to root folder( sometimes it may need to place it one step back folder of the root) and paste the following code there

           allow_url_fopen = On;

I, personally get effet by using the above solutions.

how write shorthand if else condition in php

If else condition is the first syntax that a programmer learn.
Generally we use like below condition:
if(condition)
{
   do some task
}
else
{
   do some task.
}

but you can use a short hand way, that will reduce your line of codes.

(condition) ? task1  :  task2

ie. if condition is ok the it will do task1 otherwise it will do task2

example:
<?php
$signal = '0';
$signal == '1' ? $message = 'I am right' : $message = 'I am wrong';
echo $message;
?>

Just copy and paste this code to a file and run in server. you will understand it.

Change  $signal variable, then it will do second task.

how off magic_quotes in php server

In php server you may need to On or Off different functions. Here has discussed how you can off

magic_quotes_gpc
magic_quotes_runtime
and magic_quotes_sybase

 you can off this functions by different ways. At first you can ask server authority to off it by changing this function On or Off.

or

you can write on .htaccess file

or

you can create a php.ini file and upload it to in your server root.

i have tried all of the above ways to Off magic_quotes_gpc , but could not.
Then i got a solution which is to create a php5.ini ( not php.ini ) and write the following codes to the file.

magic_quotes_gpc = Off;
magic_quotes_runtime = Off;
magic_quotes_sybase = Off;

Then i see it is Off now.

It is used for joomla 3 version articles edit for some servers.
