尝试将 url 的 preg_replace 部分用作 php 变量

发布于 2024-10-18 20:05:25 字数 1010 浏览 3 评论 0原文

我们的网站在开头有这个调用来查找页面的名称（例如product.html，product = name）并向其添加“-tabs”以生成变量$block_name：

    <? $current_url = $_SERVER['REQUEST_URI']; // this will return everything after the http://www.domain.xx including preceding "/"
$block_name = preg_replace ("/^(?:.*)\/(.*).html$/", "$1-tabs" , $current_url); ?>

然后该变量用于稍后调用静态块这个：

    <?php echo $this->getLayout()->createBlock('cms/block')->setBlockId($block_name)->toHtml() ?>

如果有人访问 http://example.com/product.html ，它就可以正常工作，但是如果我使用任何 URL 跟踪，例如 Analytics，并且 URL 末尾有以下内容：

http://example.com/product.html?utm_source=newsletter&utm_campaign=product_launch&utm_medium=email

然后变量未正确创建，静态块未加载。

有没有办法忽略 .html 之后的任何内容，以便任何跟踪附加都不会影响静态块加载？

谢谢！

Our site has this call at the beginning to find the page's name (e.g. product.html, product = name) and adds '-tabs' to it to produce the variable $block_name:

    <? $current_url = $_SERVER['REQUEST_URI']; // this will return everything after the http://www.domain.xx including preceding "/"
$block_name = preg_replace ("/^(?:.*)\/(.*).html$/", "$1-tabs" , $current_url); ?>

The variable is then used to call a static block later with this:

    <?php echo $this->getLayout()->createBlock('cms/block')->setBlockId($block_name)->toHtml() ?>

It works fine if someone goes to http://example.com/product.html, but if I use any url tracking, like Analytics, and the url has this at the end:

http://example.com/product.html?utm_source=newsletter&utm_campaign=product_launch&utm_medium=email

Then the variable isn't created properly and the static block doesn't load.

Is there a way to ignore anything after the .html so that any tracking appending doesn't impact the static block loading?

Thanks!

preg_replace("/^(?:.*)\/(.*).html\??.*$/", "$1-tabs" , $current_url)

我建议首先在该位置上使用 parse_url ，这将剥离获取变量。从那里，您可以按照当前的方式操纵它。

$pathOnly = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
$block_name = preg_replace(...);

I would recommend using parse_url on the location first, which will strip off the get variables. From there, you can manipulate it as you currently are.

$pathOnly = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
$block_name = preg_replace(...);

由于您使用的是 Magento 并且似乎是在模板内编写代码，因此您可以执行以下操作：

$_product = Mage::registry('product');
if ($_product) $block_name = $_product->getUrlKey();

产品页面上的多个模板已经为您定义了 $_product，这使得它变得更加容易。

当以非 SEO 方式请求页面（例如“http://www.example.com/catalog/product/view/id/123/”）或 URL 中包含类别名称时，此方法有效。 $_SERVER 无法处理这些情况。使用 $_SERVER 中未经验证的值允许攻击者将值插入到您的代码中，这绝对是不好的。

Since you're using Magento and appear to be writing code inside a template you can do this:

$_product = Mage::registry('product');
if ($_product) $block_name = $_product->getUrlKey();

Several templates on the product page already define $_product for you which makes it even easier.

This way works when a page is requested the non-SEO way, such as "http://www.example.com/catalog/product/view/id/123/", or when a category name is in the URL. $_SERVER could not handle these cases. Using an un-validated value from $_SERVER allows an attacker to insert values into your code which is definitely bad.
