今天学习了CI的Model模型，总的来说Model完全就是用来给数据库打交道用了。
在models文件架建立blog_model.php用于给文章的数据增加，更新，查询的Model。
<?php class Blog_model extends Model {
public $post_title;
public $post_content;
public $post_date;
function __contrust(){
parent::Model();
}
function insert_art(){
$this->post_content = $this->input->post('content');
$this->post_title = $this->input->post('title');
$this->post_date = date('Y-m-d H:m:s');
$this->db->insert('posts',$this);
}
function update_art($id){
$this->post_content = $this->input->post('content');
$this->post_title = $this->input->post('title');
$this->post_date = date('Y-m-d H:m:s');
$this->db->update('posts',$this,array('id'=>$id));
}
function get_ten_art() {
$sql = "select post_content,post_title,post_date from wp_posts limit 3";
$query = $this->db->query($sql);
return $query->result_array();
} } ?>
在控制器页面：
load->model('Blog_model','',TRUE);
}
function index(){
$data['title'] = 'my web';
$data['art'] = $this->Blog_model->get_ten_art();
$this->load->view('blog_view',$data);
}
function insert(){
$this->Blog_model->insert_art();
}
function update($id){
$this->Blog_model->update_art($id);
}
}
?>
