动态引用 文件 include 支持变量解析
今天实例中用到了需要动态include文件 这样的方法,但thinkPHP不支持动态解析
。
使用场景: 用户登录后,根据等级调用不同的显示页面,因此需要动态引入文件,而thinkPHP恰恰又不支持动态引入,只好自己想办法了。
那应该怎么去使用呢?
如图所示:
以上就是数据库对应着文件。
再紧接着就是用户登录成功后,要调用不同的Level 也是不同的menu文件 ,如需要调用menu1.tpl 或 menu2.tpl 等。
但thinkPHP不支持动态引用,怎么办?
我个人的解决方案:
看图:<if><br>
<include></include><br>
<else></else><br>
<include></include><br>
</if>
说了,这里有对应着level 这个level是哪里来的呢? 是在controller中注入的
看图示:
为了给大家看的更明白,我把登录保存在session的数据,帖出来给大家看一下:免的不清楚是怎么回事
需要修改 \ThinkPHP\Library\Think\Template.class.php 对应着parseInclude() 方法:具体修改如图所示:
编辑:\ThinkPHP\Library\Think\Template.class.php 代码如下:protected function parseInclude($content, $extend = true){ <br>
// 解析继承<br>
if($extend)<br>
$content = $this->parseExtend($content);<br>
// 解析布局<br>
$content = $this->parseLayout($content);<br>
$begin = $this->config['taglib_begin'];<br>
$end = $this->config['taglib_end'];<br>
// 读取模板中的include标签<br>
$find = preg_match_all('/'.$begin.'include\s(.+?)\s*?\/'.$end.'/is',$content,$matches);<br>
if($find) {<br>
for($i=0;$i
$include = $matches[1][$i];<br>
$array = $this->parseXmlAttrs($include);<br>
$file = $array['file'];<br>
//$view=Think::instance('Think\View');<br>
/*<br>
* 解析说明<br>
* 由于thinkPHP不能动态include文件<br>
* 因此这里需要做一些调整<br>
* 看看是否存在 append<br>
* **/<br>
if(isset($array['append'])){<br>
if(isset($array[isvar]) && $array[isvar]=="true"){<br>
$append=$this->get($array['append']);<br>
unset($array['isVar']);<br>
}else{<br>
$append=$array['append'];<br>
}<br>
$file=$file.$append;<br>
unset($array['append']);<br>
}<br>
if(isset($array['replace'])){<br>
if(isset($array[isVar]) && $array[isVar]=="true"){<br>
$file=$this->get($array['replace']);<br>
unset($array['isVar']);<br>
}else{<br>
$file=$array['replace'];<br>
}<br>
unset($array['replace']);<br>
}<br>
unset($array['file']);<br>
$content = str_replace($matches[0][$i],$this->parseIncludeItem($file,$array,$extend),$content);<br>
}<br>
}<br>
return $content;<br>
}
需要的朋友拿走!!!!!!!!!!!
