如何將PHP腳本從MediaWiki更改爲Wordpress插件？

Question

我正在從事一個項目，其中我有MediaWiki PHP Scripts，它將DB的出版物信息導入出版物頁面。

我需要將這些腳本轉換爲Wordpress插件，但我不知道最好的方法來做到這一點。現在相當丟失，我嘗試做Tutorial: Writing a simple WordPress plugin from scratch，但我沒有成功，我仍然沒有這個工作。

原始鏈接到MediaWiki代碼

在這裏你會看到我原來鏈接到MediaWiki代碼：

<?php 


# 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[] = "wfExampleExtension"; 

//---------------------------------------------------------------------------

// 
// Register the extension with the WikiText parser. 
// The first parameter is the name of the new tag. In this case it defines

所以我究竟需要知道的是：

1）不應該WordPress的能夠解釋（例如鏈接到MediaWiki標籤：<server-id what='publications' cc='IP02'></server-id>），並自動做到這一點？

2）哪裏可以找到關於這種遷移的更多文檔？

3）我做錯了嗎？

Answer 1

WordPress和MediaWiki是獨立的應用程序，不能指望爲其中一個插件直接移植到另一個插件上。如果你幸運的話，一些代碼可能是可重用的，但它不會像剪切和粘貼一樣簡單。這兩個應用程序有不同的做事方式。 1）不，WordPress不能理解這些標籤。 WordPress可以通過額外的插件瞭解MediaWiki樣式markdown標籤，但我不認識你突出顯示的標籤示例。

2）我認爲你目前的方法是合理的，你需要了解MediaWiki代碼在做什麼，並在WordPress插件中重新創建。我懷疑除了花些時間來掌握WP插件之外，還有其他捷徑。如果你喜歡編碼和編寫插件，這是花費時間。能夠自定義WordPress是非常有用的。

3）除了自己重新編碼它的另一種選擇將是看看是否有一個WordPress插件，做你正在尋找。你的問題沒有詳細說明你想要添加的功能是什麼。

爲MediaWiki和WordPress編寫了插件，我發現使用起來更輕鬆愉快。
