PHP 与HTML Purifier 错误：未定义变量：dirty_html

发布于 2024-08-26 22:31:51 字数 1238 浏览 7 评论 0原文

我正在尝试安装 HTML Purifier http://htmlpurifier.org/ 但收到以下错误未定义变量： dirty_html。我想知道如何解决这个问题？

这是 PHP 代码。

 require_once '../../htmlpurifier/library/HTMLPurifier.auto.php';

 $config = HTMLPurifier_Config::createDefault();
 $config->set('Core.Encoding', 'UTF-8'); // replace with your encoding
 $config->set('HTML.Doctype', 'XHTML 1.0 Strict'); // replace with your doctype
 $purifier = new HTMLPurifier($config);

 $clean_html = $purifier->purify($dirty_html);

这是我的 html 表单。

<form method="post" action="index.php">
    <fieldset>
        <ul>
            <li><label for="about-me">About Me: </label>
            <textarea rows="8" cols="60" name="about-me" id="about-me"></textarea></li>

            <li><label for="my-interests">My Interests: </label>
            <textarea rows="8" cols="60" name="interests" id="interests"></textarea></li>

            <li><input type="submit" name="submit" value="Save Changes" class="save-button" />
        </ul>
    </fieldset>

</form>

I'm trying to install HTML Purifier http://htmlpurifier.org/ but I get the following error Undefined variable: dirty_html. I was wondering how can I fix this problem?

Here is the PHP code.

 require_once '../../htmlpurifier/library/HTMLPurifier.auto.php';

 $config = HTMLPurifier_Config::createDefault();
 $config->set('Core.Encoding', 'UTF-8'); // replace with your encoding
 $config->set('HTML.Doctype', 'XHTML 1.0 Strict'); // replace with your doctype
 $purifier = new HTMLPurifier($config);

 $clean_html = $purifier->purify($dirty_html);

Here is my html form.

<form method="post" action="index.php">
    <fieldset>
        <ul>
            <li><label for="about-me">About Me: </label>
            <textarea rows="8" cols="60" name="about-me" id="about-me"></textarea></li>

            <li><label for="my-interests">My Interests: </label>
            <textarea rows="8" cols="60" name="interests" id="interests"></textarea></li>

            <li><input type="submit" name="submit" value="Save Changes" class="save-button" />
        </ul>
    </fieldset>

</form>

目前还不清楚你想要净化什么。一些 $_POST 变量？您收到该错误是因为您尚未定义 $dirty_html。例如，如果您想净化 about_me 字段，请使用

$clean_html = $purifier->purify($_POST['about_me']);

It's not clear what you want to purify. Some $_POST vars? You get that error because you have not defined $dirty_html. For example, if you want to purify the about_me field, use

$clean_html = $purifier->purify($_POST['about_me']);

$dirty_html 应该是网页的 HTML

看起来您正在向 HTML 添加 DOCTYPE 和编码，所以我假设您会像这样使用它：

$dirty_html =<<<DIRTYHTML
<form method="post" action="index.php">
    <fieldset>
        <ul>
            <li><label for="about-me">About Me: </label>
            <textarea rows="8" cols="60" name="about-me" id="about-me"></textarea></li>

            <li><label for="my-interests">My Interests: </label>
            <textarea rows="8" cols="60" name="interests" id="interests"></textarea></li>

            <li><input type="submit" name="submit" value="Save Changes" class="save-button" />
        </ul>
    </fieldset>

</form>
DIRTYHTML;

$clean_html = $purifier->purify($dirty_html);
echo $clean_html;

$dirty_html should be the HTML of the webpage

It looks like you're adding a DOCTYPE and Encoding to your HTML so I assumed that you would use it like this:

$dirty_html =<<<DIRTYHTML
<form method="post" action="index.php">
    <fieldset>
        <ul>
            <li><label for="about-me">About Me: </label>
            <textarea rows="8" cols="60" name="about-me" id="about-me"></textarea></li>

            <li><label for="my-interests">My Interests: </label>
            <textarea rows="8" cols="60" name="interests" id="interests"></textarea></li>

            <li><input type="submit" name="submit" value="Save Changes" class="save-button" />
        </ul>
    </fieldset>

</form>
DIRTYHTML;

$clean_html = $purifier->purify($dirty_html);
echo $clean_html;
