JHtml-"email.cloak"在joomla中使用preg_replace()时无法识别电子邮件地址 [英] JHtml-"email.cloak" doesn't recognize email address when using preg_replace() in joomla

问题描述

我尝试使用JHtml::_("email.cloak", "[e-mail]")用php替换php模块中文本中的电子邮件地址，以便将其隐藏在joomla 3.9.2网页上.

I try to substitute an email-address within a text in a module with php using JHtml::_("email.cloak", "[e-mail]"), in order to cloak it on a joomla 3.9.2 webpage.

使用以下示例代码:

<div>
<?php
    $text = "This is a text with [e-mail] an e-mail address in it";
    $test_text_email = "[e-mail]";
    echo JHtml::_("email.cloak", $test_text_email)."<br>";
    echo preg_replace('/([a-zA-Z0-9_\-\.]*@\\S+\\.\\w+)/', JHtml::_("email.cloak", "$1"),$text)."<br>";
?></div>

Jhtml:_("email.cloak"，...当只交出一个简单的字符串时效果很好(请参阅下面的$ test_text_email)当使用preg_replace在文本中搜索电子邮件地址时，可以正确找到电子邮件子字符串，但由于函数似乎无法再识别"@"符号，因此隐藏功能无法正常工作，结果如下:

Jhtml:_("email.cloak",... works great when just handing over a simple string (see $test_text_email below). When searching for an email address within a text using preg_replace, the email substring is found correctly, yet the cloaking doesn't work correctly as the function doesn't seem to recognize the "@" symbol anymore with the following result:

<span id="cloak7c9ea7a5340755f2f7e1d4f0c8b45675"><a href="mailto:[e-mail]">[e-mail]</a></span>
This is a text and <span id="cloak88a24a939973cdd7ec9f3d1fb591b7a5"><a href="mailto:[e-mail]@">[e-mail]@</a></span> an e-mail address 

生成的javascript证明由preg_replace()找到的正确子字符串，但是没有发生任何伪装，仅在末尾添加了@符号(&#64).

The generated javascript proves the correct substring found by preg_replace(), but without any cloaking happening, just an @ symbol is added at the end (&#64).

<script type="text/javascript">
            document.getElementById('cloak3fd71e407852d6d7593b726a0f41ca38').innerHTML = '';
            var prefix = '&#109;a' + 'i&#108;' + '&#116;o';
            var path = 'hr' + 'ef' + '=';
            var addy3fd71e407852d6d7593b726a0f41ca38 = '[e-mail]' + '&#64;';
            addy3fd71e407852d6d7593b726a0f41ca38 = addy3fd71e407852d6d7593b726a0f41ca38 + '';
            var addy_text3fd71e407852d6d7593b726a0f41ca38 = '[e-mail]' + '&#64;' + '';document.getElementById('cloak3fd71e407852d6d7593b726a0f41ca38').innerHTML += '<a ' + path + '\'' + prefix + ':' + addy3fd71e407852d6d7593b726a0f41ca38 + '\'>'+addy_text3fd71e407852d6d7593b726a0f41ca38+'<\/a>';
    </script>

脚本中的正确行如下所示:

The correct line in the script is shown below:

    var addy1ef8a36d65e0cc59448f875761cc1465 = 'some' + '@';addy1ef8a36d65e0cc59448f875761cc1465 = addy1ef8a36d65e0cc59448f875761cc1465 + 'email' + '.' + 'com';

有什么想法为什么要对字符串进行不同的处理? 预先感谢！

Any ideas why the strings are handled differently? Thanks in advance!

推荐答案

您不能对preg_replace()的替换参数执行操作.您需要致电preg_replace_callback().

You can't perform manipulations on the replacement parameter of preg_replace(). You will need to call preg_replace_callback().

代码:(演示)

$text = "This is a text with [e-mail] an e-mail address in it";

echo preg_replace_callback(
        '~[\w.-]+@(?:[\w-]+\.)+\w+~',
        function($m) {
            return JHtml::_("email.cloak", $m[0]);
        },
        $text
     );

• a-zA-Z0-9_更简单地浓缩为\w
• .不需要在字符类中转义.
如果
• -位于字符类的开始或结尾，或者紧随字符类中的字符范围"(例如0-9-)，则不需要转义.
• 您的图案中不需要那些双斜杠
在某些情况下
• 在\S之后出现贪婪的+可能不是一个好主意
• a-zA-Z0-9_ is more simply condensed to \w
• . doesn't need to be escaped in a character class.
• - doesn't need to be escaped if it is at the start or end of the character class or if it immediately follows a "range of characters" in the character class (e.g. 0-9-).
• you don't need those double slashes in your pattern
• a greedy + after \S may be a bad idea in some scenarios
