Thinkphp 框架扩展之标签库驱动原理与用法分析

namespace Think\Template\Taglib;
use Think\Template\TagLib;
Class Test extends TagLib{
}

protected $tags  = array(
 // 定义标签
 'input'  =>  array('attr'=>'type,name,id,value','close'=>0), // input标签
 'textarea' =>  array('attr'=>'name,id')，
 );

// input标签解析
public function _input($tag,$content)  {
  $name  =  $tag['name'];
  $id  =  $tag['id'];
  $type  =  $tag['type'];
  $value  =  $this->autoBuildVar($tag['value']);
  $str = "<input type='".$type."' id='".$id."' name='".$name."' value='".$value."' />";
  return $str;
}
// textarea标签解析
public function _textarea($tag,$content)  {
  $name =  $tag['name'];
  $id  =  $tag['id'];
  $str  =  '<textarea id="'.$id.'" name="'.$name.'">'.$content.'</textarea>';
  return $str;
}

<taglib name='Test' />

<test:input type='radio' id='test' name='mail' value='value' />
<test:textarea id="content" name="content">$value</test:textarea>

$this->assign('value','my test value');

<input type='radio' id='test' name='mail' value='my test value' />
<textarea id="content" name="content">my test vale</textarea>
