我终于尝试了一些CodeIgniter,我现在卡住了。
public function get_news($slug = FALSE){
if($slug === FALSE){
// if there is no slug specified, pull all records from the 'wp_posts' table
$this->db->select('post_title, post_content, post_name');
$this->db->where('post_status', 'published');
$this->db->where('post_type', 'post');
$this->db->order_by("post_date", "desc");
$this->db->order_by("post_title", "asc");
$query = $this->db->get('wp_posts');
var_dump($query);
// return the resulting array
return $query->result_array();
}else{
// if it does exist, pull only the record(s) specified where column 'slug' = the parameter
$this->db->select('post_title, post_content, post_name');
$query = $this->db->get_where('wp_posts', array('post_name' => $slug));
// return the resulting array
return $query->row_array();
}
}
class News extends CI_Controller{
public function __construct(){
parent::__construct();
// located @ /application/models/news_model.php
$this->load->model('news_model');
}
// pull in all news items
public function index(){
$data['news'] = $this->news_model->get_news();
// give the page a title
$data['title'] = 'Articles Archive';
$data['c_year'] = date('Y');
// Load the header template
$this->load->view('templates/header', $data);
// Load the page
$this->load->view('news/index', $data);
// Load the footer template
$this->load->view('templates/footer', $data);
}
// pull in only the news item(s) where the slug matches
public function view($slug){
$data['news_item'] = $this->news_model->get_news($slug);
// give the page a title
$data['title'] = $data['news_item']['title'];
$data['c_year'] = date('Y');
// Load the header template
$this->load->view('templates/header', $data);
// Load the page
$this->load->view('news/view', $data);
// Load the footer template
$this->load->view('templates/footer', $data);
}
}
与数据库的连接很好,但我在视图中只返回show_404();
,因为有no
条记录。
直接针对数据库运行类似的查询确实会返回我的所有记录。
以下是var_dump
:
object(CI_DB_mysql_result)#18 (8) {
["conn_id"]=> resource(3) of type (mysql link persistent)
["result_id"]=> resource(4) of type (mysql result)
["result_array"]=> array(0) { }
["result_object"]=> array(0) { }
["custom_result_object"]=> array(0) { }
["current_row"]=> int(0) ["num_rows"]=> int(0)
["row_data"]=> NULL
}
我在这里做错了什么?
答案 0 :(得分:0)
更改:$this->db->where('post_status', 'published');
收件人:$this->db->where('post_status', 'publish');
这个问题已经解决了......这是一个漫长的一周......
