Overview

This (simple) extension could be used for the donations-sites, if therefor you have a PayPal-Account.

这个简单的扩展，可以用来添加网站的“捐赠”功能。需要你已经有了一个Paypal帐号。

This extension will create a PayPal-Button, which leads users to your PayPal-Donation-Site.

这个扩展会生成一个Paypal键，引导用户到Paypal的付款页面。

Create a new site in your extension-folder, named "PayPal.php" with following content:

在你的extension目录下，建立一个名为“PayPal.php”的文件，内容为：

<?php
# Example WikiMedia extension
# with WikiMedia's extension mechanism it is possible to define
# new tags of the form
# <TAGNAME> some text </TAGNAME>
# the function registered by the extension gets the text between the
# tags as input and can transform it into arbitrary HTML code.
# Note: The output is not interpreted as WikiText but directly
#       included in the HTML output. So Wiki markup is not supported.
# To activate the extension, include it from your LocalSettings.php
# with: include("extensions/YourExtensionName.php");

$wgExtensionFunctions[] = "wfPayPal";

function wfPayPal() {
    global $wgParser;

    $wgParser->setHook( "paypal", "renderPayPal" );
}

# The callback function for converting the input text to HTML output
function renderPayPal( $input ) {
    # $argv is an array containing any arguments passed to the
    # extension ike <example argument="foo" bar>..
    $output = "<br/>$input";
    $output .= "<form action='https://www.paypal.com/cgi-bin/webscr' method='post'>";
    $output .= "<input type='hidden' name='cmd' value='_s-xclick'>";
    $output .= "<input type='image' src='https://www.paypal.com/de_DE/i/btn/x-click-but04.gif' border='0' name='submit' alt='Zahlen Sie mit PayPal - schnell, kostenlos und sicher!'>";
    $output .= "<input type='hidden' name='encrypted' value=' THIS_SHOULD_BE_REPLACED'>";
    $output .= "</form>";
    return $output;
}
?>

Replace the "THIS_SHOULD_BE_REPLACED"-section with your code, brought to you by PayPal

用Paypal的代码替换"THIS_SHOULD_BE_REPLACED"这一部分

(should be something like -----BEGIN PKCS7-----MIIHNwY (.........)-----END PKCS7-----).

(就是那串如同这个一样的： -----BEGIN PKCS7-----MIIHNwY (.........)-----END PKCS7-----).

Open your LocalSettings.php, and insert at the end of file:

打开LocalSettings.php, 在文件的最后插入:

include("extensions/PayPal.php");

If you do so, you can make the PayPal-Button visible by using:

如果你已经完成了这些，你就可以在页面上用下面的代码显示Paypal键了:

<paypal></paypal>

其他方法
