为CMS创建自定义"html"标签? [英] Creating custom "html"-tags for CMS?
问题描述
我正在使用CMS为PHP中的Web应用程序工作，它需要缩短存储在数据库中的插入(嵌入)内容(例如youtube或vimeo的视频)的过程，方法如下:
I am working with a CMS for a web app in PHP, that has the needs of shortening the process for inserting (embedding) stuff, like a video from youtube or vimeo by wroting the following, which are stored in the database:
<youtube id="wfI0Z6YJhL0" />
在进行某种替换后会输出以下内容:
Which would output the following after some sort of replace:
<!-- Custom formatting before object !-->
<object width="640" height="385"><param name="movie" value="http://www.youtube-nocookie.com/v/wfI0Z6YJhL0&hl=sv_SE&fs=1?rel=0&color1=0xe1600f&color2=0xfebd01"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube-nocookie.com/v/wfI0Z6YJhL0&hl=sv_SE&fs=1?rel=0&color1=0xe1600f&color2=0xfebd01" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="385"></embed></object>
<!-- Custom formatting after object !-->
如何在PHP中做到这一点?

推荐答案
我编写了一个类，可以完全满足您对自己的cms的要求.我已经为您上传了src，就好像我从未发布过它一样，其源代码是根据BSD样式许可发布的. 自定义标签
I've written a class that does exactly what you ask for my own cms. I've uploaded the src for you as although I've never released it the source is released under a BSD style license. Custom Tags
基本上，它可以让您按照自己的要求去做.在课堂上，有一些示例自定义标签，因此我不会在此处粘贴代码.让我知道你的情况.
It basically allows you do do exactly what you ask for. In the class there are some example custom tags so I won't paste code here. Let me know how you go.
按要求编写示例代码. :-)
Edit 1: Example Code as requested. :-)
我应该添加它支持隐藏的自定义标签.
Edit 2: I should add it supports buried custom tags.
它还支持内联模板和标签替换，即
Edit 3: It also supports inline templating and tag substitution, ie
<ct:inline some="attribute">
This is an in line template. <br />
This is a #{tag} that can be accessed by the callback function
</ct:inline>
PHP/HTML: example.php
PHP/HTML: example.php
<?php
$current_dir = dirname(__FILE__).DIRECTORY_SEPARATOR;
require_once dirname($current_dir).DIRECTORY_SEPARATOR.'customtags.php';
$ct = new CustomTags(array(
'parse_on_shutdown' => true,
'tag_directory' => $current_dir.'tags'.DIRECTORY_SEPARATOR,
'sniff_for_buried_tags' => true
));

自定义标签PHP功能: tags/youtube/tag.php :
Custom Tag PHP Function: tags/youtube/tag.php:
function ct_youtube($tag)
{
return '<object id="'.$tag['attributes']->id.'" value="http://www.youtube.com/v/'.$tag['attributes']->id.'" /><param ......>';
}
输出:
