模型
首先,您不必在控制器中添加对数据库的直接访问。对于所有数据库访问代码,您必须创建模型。 在上面的代码中,您在direct controller中添加了数据库访问代码,根据MVC架构,这在逻辑上是错误的。 下面是根据MVC编写的代码,所有数据库访问代码都驻留在模型中。 批量插入的主要问题是
函数插入()
当然可以,请检查一下
<?php
class Student extends CI_Controller {
public function _construct()
{
parent::_construct();
//call model
$this->load->model("StudentModel","m");
}
function index()
{
$this->load->view("index");
}
function savedata()
{
$stdarray = array();
$stdarray[] = array('studentname' => 'Reddy' ,'gender' => 'Male' ,'phone' => '456879');
$stdarray[] = array('studentname' => 'Yalla' ,'gender' => 'Female' ,'phone' => '12345678');
//mean that insert into database table name tblstudent
$this->db->insert_batch('tblstudent',$data);
$this->m->insert($stdarray);
//mean that when insert already it will go to page index
redirect("Student/index");
}
function edit($id)
{
$row=$this->m->getonerow($id);
$data['r']=$row;
$this->load->view('edit',$data);
}
function update($id)
{
$updateArray = array();
$updateArray['studentname'] = $this->input->post('studentname');
$updateArray['gender'] = $this->input->post('gender');
$updateArray['phone'] = $this->input->post('phone');
$whereArray = array();
$whereArray['id'] = $id;
$this->m->updateRow($updateArray,$whereArray);
redirect("Student/index");
}
function delete($id)
{
$whereArray = array();
$whereArray['id'] = $id;
$this->m->deleteRow($whereArray);
redirect("Student/index");
}
}
?>
重要提示:此外,您必须对所有直接发送到数据库的输入使用转义函数,以维护SQL注入的安全性。对于多值,您的html代码是什么?
