用破折号显示 URL slug 的问题 [英] Problem in displaying a URL slug with dash

问题描述

我为我的故事 URL 制作了一个带破折号的 slug，例如:

I made a slug with dash for my stories URLs such as:

使用 slug 而不是 ID 获取记录

这是我创建 slug 的代码:

This is my code to create slug :

function Slugit($title) {
    $title = strip_tags($title);
    // Preserve escaped octets.
    $title = preg_replace('|%([a-fA-F0-9][a-fA-F0-9])|', '---$1---', $title);
    // Remove percent signs that are not part of an octet.
    $title = str_replace('%', '', $title);
    // Restore octets.
    $title = preg_replace('|---([a-fA-F0-9][a-fA-F0-9])---|', '%$1', $title);


    $title = remove_accents($title);
    if (seems_utf8($title)) {
        if (function_exists('mb_strtolower')) {
            $title = mb_strtolower($title, 'UTF-8');
        }
        $title = utf8_uri_encode($title, 500);
    }

    $title = strtolower($title);
    $title = preg_replace('/&.+?;/', '', $title); // kill entities
    $title = str_replace('.', '-', $title);
    $title = preg_replace('/[^%a-z0-9 _-]/', '', $title);
    $title = preg_replace('/\s+/', '-', $title);
    $title = preg_replace('|-+|', '-', $title);
    $title = trim($title, '-');


    return $title;
}

正如你所看到的破折号，到这里，一切都很好.但是当我点击链接时，它无法打开并找到我的数据库，因为它以正常方式保存并且没有破折号.

As you can see dashes, up to here, everything is fine. But when I click on the link, it can not open and find it my database as it's saved in normal and with no dashes.

所以我写了一些东西来删除破折号:

So I wrote something to remove dashes:

$string = str_replace('-', ' ', $string);

但是当URL中有?或.时，就不能显示了！

But when there is ? or . in URL, then it can not display!

找回原始网址有什么帮助吗?！

Any help to retrieve back the original URL?!

推荐答案

当你有这样一个 URL 时:

When you have an URL such as this one :

https://stackoverflow.com/questions/2647789/problem-in-displaying-a-slug-with-dash

problem-in-displaying-a-slug-with-dash 部分不是很重要:它只是很好:

The problem-in-displaying-a-slug-with-dash part is not quite important : it's just nice :

• 显示
• 供用户阅读，并了解问题的内容
• 对于搜索引擎，作为 SEO 机制.

真正重要的是，在那个 URL 中，是 2647789 部分:它是数据库中问题的标识符-- 即用于加载问题的 URL 部分.

What's really important, in that URL, is the 2647789 part : it's the identifier of the question in the database -- i.e. it's that part of the URL that's used to load the question.

这意味着无需将 slug 转换为用户最初输入的内容:唯一重要的是您在每个 URL 中传递数据的标识符，并使用它来查找数据.

This means there is no need to convert the slug to what was first typed by the user : only thing that matters is that you pass the identifier of your data in each URL, and use it to find your data back.

而且，如果您想要某种证据:尝试去显示带有破折号的 URL slu 的问题 没有 slug :你会看到你的问题加载得很好;-)

And, if you want some kind of proof : try going to Problem in displaying a URL slug with dash without the slug : you'll see that your question loads just fine ;-)
