phpcms has a controller.

What is a controller in phpcms

phpcms controller is the class file of the module, which is stored under phpcms/modules. Each module has an independent naming method. The class name is in the file name.php naming format. The controller class inherits the system's function library by default and can be used directly. The class name of the controller class and the controller file name must be the same.

Add a new controller

Next we will create a new test folder under phpcms/modules, and create a new one named mytest.php in the test folder file, add the following code in the file:

defined('IN_PHPCMS') or exit('No permission resources.');class mytest {    function __construct() {
    }    public function init() {
        $myvar = '这是默认加载!';        echo $myvar;
    }    public function mylist() {
        $myvar = '这是自定义list!';        echo $myvar;
    }
}

Then we can enter the following access method in the browser

http://domain name/index.php?m=test&c= mytest

The init() method is loaded by default

http://domain name/index.php?m=test&c=mytest&a=mylist

Loading is the mylist method

Template introduction

Front-end template

Website front-end template location Under the phpcms/templates/default/ module

We add the loading template method in the init() method of the controller mytest.php file

include template('test', 'mytest', 'default');

Create a new one under the phpcms/templates/default/ directory The test folder and mytest.html file are enough.

Backend template

The background template file is in the phpcms/modules/module name/templates directory

Controller with permissions

Backend controller

Create a new mytest_admin.php file under phpcms/modules/admin/. The file code is as follows:

defined('IN_PHPCMS') or exit('No permission resources.');
pc_base::load_app_class('admin','admin',0);
class mytest_admin extends admin{
    function __construct()
    {
    }
    public function index(){
        echo "后台控制器";
    }
 
}

Access address: http://domain name /index.php?m=admin&c=mytest_admin&a=index

phpcms custom model

Introduce the model on the class

pc_base::load_sys_class('model', '', 0);

Then the class extends inheritance model

Add the following code in the __construct method:

$this->db_config = pc_base::load_config('database');
$this->db_setting = 'default';
parent::__construct();

Query statement

function init(){
    $sql = 'select * from v9_news ';
    $data = $this->get_array_by_sql($sql);
    var_dump($data);
}
public function sql_query($sql) {
    if (!empty($this->db_tablepre)) $sql = str_replace('phpcms_', $this->db_tablepre, $sql);
    return parent::query($sql);
}
 
public function fetch_next() {
    return $this->db->fetch_next();
}
//通过SQL语句查询一条结果
public function get_one_by_sql($sql){
    $this->sql_query($sql);
    $res = $this->fetch_next();
    $this->free_result();
    return $res;
}
//通过sql语句查询数组
public function get_array_by_sql($sql){
    $this->sql_query($sql);
    $res = $this->fetch_array();
    $this->free_result();
    return $res;
}
 
//释放数据库结果资源，调用底层完成
public function free_result() {
    $this->db->free_result();
}
