posts
表中添加了slug
列
slug由post标题组成,这些代码块分别位于Posts\u模型和Posts控制器中
从模型中:
public function slug_count($slug){
$this->db->select('count(*) as slugcount');
$this->db->from('posts');
$this->db->where('slug', $slug);
$query = $this->db->get();
return $query->row(0)->slugcount;
}
public function create_post($post_image, $slug) {
$data = [
'title' => $this->input->post('title'),
'slug' => $slug,
'description' => $this->input->post('desc'),
'content' => $this->input->post('body'),
'post_image' => $post_image,
'author_id' => $this->session->userdata('user_id'),
'cat_id' => $this->input->post('category'),
'created_at' => date('Y-m-d H:i:s')
];
return $this->db->insert('posts', $data);
}
// Create slug (from title)
$slug = url_title($this->input->post('title'), 'dash', TRUE);
$slugcount = $this->Posts_model->slug_count($slug);
if ($slugcount > 0) {
$slug = $slug."-".$slugcount;
}
从控制器:
public function slug_count($slug){
$this->db->select('count(*) as slugcount');
$this->db->from('posts');
$this->db->where('slug', $slug);
$query = $this->db->get();
return $query->row(0)->slugcount;
}
public function create_post($post_image, $slug) {
$data = [
'title' => $this->input->post('title'),
'slug' => $slug,
'description' => $this->input->post('desc'),
'content' => $this->input->post('body'),
'post_image' => $post_image,
'author_id' => $this->session->userdata('user_id'),
'cat_id' => $this->input->post('category'),
'created_at' => date('Y-m-d H:i:s')
];
return $this->db->insert('posts', $data);
}
// Create slug (from title)
$slug = url_title($this->input->post('title'), 'dash', TRUE);
$slugcount = $this->Posts_model->slug_count($slug);
if ($slugcount > 0) {
$slug = $slug."-".$slugcount;
}
为了实现我的SEO目标,我在中考虑并尝试了这种方法,但由于有许多功能需要ID(例如通过AJAX删除帖子)和其他不需要SLUG(编辑帖子)的功能,我无法(也不愿意)在控制器中实质性地修改帖子查看方法
public function post($id) {
$data = $this->Static_model->get_static_data();
$data['pages'] = $this->Pages_model->get_pages();
$data['categories'] = $this->Categories_model->get_categories();
$data['posts'] = $this->Posts_model->sidebar_posts($limit=5, $offset=5);
$data['post'] = $this->Posts_model->get_post($id);
if ($data['categories']) {
foreach ($data['categories'] as &$category) {
$category->posts_count = $this->Posts_model->count_posts_in_category($category->id);
}
}
if (!empty($data['post'])) {
// Overwrite the default tagline with the post title
$data['tagline'] = $data['post']->title;
// Get post comments
$post_id = $data['post']->id;
$data['comments'] = $this->Comments_model->get_comments($post_id);
$this->load->view('partials/header', $data);
$this->load->view('post');
} else {
$data['tagline'] = "Page not found";
$this->load->view('partials/header', $data);
$this->load->view('404');
}
$this->load->view('partials/footer');
}
以及模型中相应的代码:
public function get_post($id) {
$query = $this->db->get_where('posts', array('id' => $id));
if ($query->num_rows() > 0) {
$data = $query->row();
// run separate query for author name
$author_query = $this->db->get_where('authors', array('id' => $data->author_id));
if ($author_query->num_rows() == 1) {
$author = $author_query->row();
$data->first_name = $author->first_name;
$data->last_name = $author->last_name;
} else {
$data->first_name = 'Unknown';
$data->last_name = '';
}
return $data;
}
}
在singe post视图中,用slug替换post id的简单、不太“侵入性”的方法是什么?好吧,我认为您可以将id和slug放在同一个函数/url上,例如
/id/slug
。这样,你总是有你的id
,搜索引擎优化也很高兴,因为url有页面标题(slug)。然后在你的函数上,你可以有公共函数post($id,$slug=”“){
在模型中更新
替换
public function get_post($id) {
$query = $this->db->get_where('posts', array('id' => $id));
与
在控制器中更新
替换
public function post($id) {
与
替换
$data['post'] = $this->Posts_model->get_post($id);
与
同时更新您的路由以获得更好的用户友好url
//If you categorize your blog
$route['blog-category/(:any)'] = 'blogController/blogFunction/$1';
//this will accept any uri
$route['(:any)/(:any)'] = 'blogController/blogFunction'
这可能并不总是好的做法,假设slug实际上包含一个数字(产品id或序列号)和url中存在的另一个id,这对SEO是有害的。你会怎么做?什么是最佳的方法?所以你想做的是让post/123和post/some post(其中id是123)给你同样的结果,对吗?当我移动到slug时,我这样做了…如果URL参数是数字,我只需搜索Id,否则slug就会得到帖子。是的。我应该如何实现这一点?我的帖子位于
http://localhost/ciblog/posts/post/the-post-slug
。我必须在路线中添加什么才能拥有http://localhost/ciblog/post slug
insead?这样说。$route['(:any)/(:any)]='posts/post/$1
//If you categorize your blog
$route['blog-category/(:any)'] = 'blogController/blogFunction/$1';
//this will accept any uri
$route['(:any)/(:any)'] = 'blogController/blogFunction'
