1.準備news表格，id,title,slug,text

2.新建Crud.php，並繼承

classCrudextendsCI_Controller 3. publicfunction__construct() { parent::__construct(); $this->load->database(); } 4.新增記錄 publicfunctionc() { $arrNews=array(); $arrNews['title']='第一條標題'; $arrNews['slug']='A'; $arrNews['text']='thisisatest'; var_dump($this->db->insert('news',$arrNews)); echo$this->db->insert_id(); } 5.通過id讀取一條 publicfunctionr() { $arrParams=$this->uri->uri_to_assoc(); if(empty($arrParams)||empty($arrParams['id'])){ echo'no'; return; } $this->db->from("news")->where('id=',$arrParams['id']); $res=$this->db->get(); var_dump($res->result());
} 6.讀取全部 publicfunctionra() { $res=$this->db->get("news"); var_dump($res->result()); } publicfunctionu() { $this->db->set('title','testfortitle2'); $this->db->where('id',2); var_dump($this->db->update('news')); } 7.刪除一條
publicfunctiond() { $this->db->where('id',3); var_dump($this->db->delete('news')); }
