Blog system....posts

#1
[eluser]Adam Griffiths[/eluser]
Hey,

I've got a blog system that I am building on top of CI. So far it is really simple, I'm just pulling data out of the database and displaying it in a view. But I am not showing all my posts, just the introduction. How would I make it so I can link to a page, have the URL the same as the title but with '-' instead of spaces (I know there is already a function for this so that won't be a problem) but grab only that post from the database and display it?

So if I have a post called CodeIgniter rocks my socks I can go to www.myurl.com/index.php/post/codeigniter-rocks-my-socks/ and display the post from the databse?

The only part I'm having trouble with is how do I let CI know which post to pull from the database? I had the idea of using the function to make a new string (i.e. codeigniter-rocks-my-socks) for each post then pulling that, but I've no idea how CI would know that the string is in the URL.

I would usually use $_GET but obviously I can't with CI.


Any comments will help greatly.


Thanks,
Adam Griffiths

You have to create an extra field that stores the to url segment transformed title and you select the blog post based on that field.

I've done exactly that, I save the title using the url_title helper in the database as 'slug'
and my post method looks like this
Code:
function post($slug) {
    $query = $this->db->get_where('posts', array('slug' => $slug));
    if($query->num_rows() > 0) {
        $row = $query->row();
        $this->data['post']['id'] = $row->id;
        $this->data['post']['title'] = $row->title;
        $this->data['post']['body'] = $row->body;
        $this->data['post']['date'] = $row->post_date;
        $this->load->view('blog/post',$this->data);
    } else {
        show_404($slug);
    }
}
