HTMLPurifier插件的使用
下载HTMLPurifier插件
HTMLPurifier插件有用的部分是 library
使用HTMLPurifier library类库
代码如下:
或者
代码如下:
PHP
require_once 'HTMLPurifier.includes.PHP';
require_once 'HTMLPurifier.autoload.PHP';
$config = HTMLPurifier_Config::createDefault();
?>
require_once 'HTMLPurifier.includes.PHP';
require_once 'HTMLPurifier.autoload.PHP';
$config = HTMLPurifier_Config::createDefault();
?>
官网给出的例子是
代码如下:
require_once 'HTMLPurifier.auto.PHP';
我同事常用的是
代码如下:
设置$config
configdochttp://htmlpurifier.org/live/configdoc/plain.html
例子
代码如下:
$config->set('HTML.AllowedElements',array('div'=>true,'table'=>true,'tr'=>true,'td'=>true,'br'=>true));
$config->set('HTML.Doctype','XHTML 1.0 Transitional')//html文档类型(常设)
$config->set('Core.Encoding','UTF-8')//字符编码(常设)
$config->set('HTML.Doctype','XHTML 1.0 Transitional')//html文档类型(常设)
$config->set('Core.Encoding','UTF-8')//字符编码(常设)
HTML允许的元素
div元素,table元素,tr元素,td元素,br元素new HTMLPurifier对象
代码如下:
$purifier = new HTMLPurifier($config);
调用HTMLPurifier对象的purify方法
代码如下:
$puri_html = $purifier->purify($html);
自定义一个类 HtmlPurifier.PHP
代码如下:
PHP
require_once 'HTMLPurifier.includes.PHP';
require_once 'HTMLPurifier.autoload.PHP';
class Resume_HtmlPurifier implements Zend_Filter_Interface{
protected $_htmlPurifier = null;
public function __construct($options = null)
{
$config = HTMLPurifier_Config::createDefault();
$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);}
}
?>
require_once 'HTMLPurifier.includes.PHP';
require_once 'HTMLPurifier.autoload.PHP';
class Resume_HtmlPurifier implements Zend_Filter_Interface{
protected $_htmlPurifier = null;
public function __construct($options = null)
{
$config = HTMLPurifier_Config::createDefault();
$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:
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),//禁止classes如
array('AutoFormat.RemoveEmpty',true,//去空格
array('AutoFormat.RemoveEmpty.RemoveNbsp',//去nbsp
array('URI.Disable',
);
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),//禁止classes如
array('AutoFormat.RemoveEmpty',true,//去空格
array('AutoFormat.RemoveEmpty.RemoveNbsp',//去nbsp
array('URI.Disable',
);
调用
代码如下:
$p = new Resume_HtmlPurifier($conf);
$puri_html = $p->filter($html);
$puri_html = $p->filter($html);
