在codeigniter中使用slugs [英] Using slugs in codeigniter

问题描述

我听说过人们使用lug for来产生干净的网址。我不知道它是如何工作的。
目前我有一个codeigniter网站，生成的URL像这样

I have heard of people using slugs for generating clean urls. I have no idea how it works. Currently i have a codeigniter site which generates url's like this

www.site.com/index.php/blog/view/7

从我理解的维护一个slug字段可以实现像

From what i understand by maintaining a slug field it is possible to achieve urls like

www.site.com/index.php/blog/view/once-upon-a-time

这是怎么做的？特别是对codeigniter？

How is this done? Especially in reference to codeigniter?

推荐答案

我只是将slugs存储在我的数据库表中，在 slug ，然后找到带有slug的帖子，如下所示：

I just store the slugs in my database table, in a column called slug, then find a post with the slug, like this:

public function view($slug)
{
    $query = $this->db->get_where('posts', array('slug' => $slug), 1);

    // Fetch the post row, display the post view, etc...
}

此外，要轻松从您的帖子标题中导出a，只需使用网址帮助程序的 url_title（） ：

Also, to easily derive a slug from your post title, just use url_title() of the URL helper:

// Use dashes to separate words;
// third param is true to change all letters to lowercase
$slug = url_title($title, 'dash', true);

一点奖励：您可能希望对 slug 列，确保每个帖子都有唯一的lug，所以它不会含糊不清的哪个帖子CodeIgniter应该查找。当然，您应该首先为您的帖子提供唯一的标题，但是这样做会强制实施 该规则，并防止您的应用程序卷入。

A little bonus: you may wish to implement a unique key constraint to the slug column, that ensures that each post has a unique slug so it's not ambiguous which post CodeIgniter should look for. Of course, you should probably be giving your posts unique titles in the first place, but putting that in place enforces the rule and prevents your application from screwing up.
