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
第一种方式
<?php
require_once \'HTMLPurifier.auto.php\';
$config = HTMLPurifier_Config::createDefault();
?>
或者
<?php
require_once \'HTMLPurifier.includes.php\';
require_once \'HTMLPurifier.autoload.php\';
$config = HTMLPurifier_Config::createDefault();
?>
官网给出的例子是
require_once \'HTMLPurifier.auto.php\';
我同事常用的是
require_once \'HTMLPurifier.includes.php\';
require_once \'HTMLPurifier.autoload.php\';
设置$config
configdoc
http://htmlpurifier.org/live/configdoc/plain.html
例子
$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)
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
$purifier = new HTMLPurifier($config);
调用HTMLPurifier对象的purify方法
$puri_html = $purifier->purify($html);
第二种方式
自定义一个类 HtmlPurifier.php
<?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);
}
}
?>
设置config信息
例如:
$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),
);
调用
$p = new Resume_HtmlPurifier($conf);
$puri_html = $p->filter($html);
