$config->set('Code.Encoding', 'UTF-8');
$config->set('HTML.Doctype', 'XHTML 1.0 Transitional')
if(!is_null($options)){
foreach($options as $option){
$config->set($option[0], $option[1], $option[2]);
}
}
$this->_htmlPurifier = new HTMLPurifier($config);
}
public function filter($value)
{
return $this->_htmlPurifier->purify($value);
}
}
?>
设置config信息
例如:
复制代码 代码如下:
$conf = array(
array('HTML.AllowedElements',
array(
'div' => true,
'table' => true,
'tr' => true,
'td' => true,
'br' => true,
),
false), //允许属性 div table tr td br元素
array('HTML.AllowedAttributes', array('class' => TRUE), false), //允许属性 class
array('Attr.ForbiddenClasses', array('resume_p' => TRUE), false), //禁止classes如
array('AutoFormat.RemoveEmpty', true, false), //去空格
array('AutoFormat.RemoveEmpty.RemoveNbsp', true, false), //去nbsp
array('URI.Disable', true, false),
);
