For example, there is a field named "username" in the user table. If there is anin the form, then

$User = M('User'); $data = $User->create(); echo $data['username'];

will Output "Xiao Ming", you don't need to use $_POST['username'] to receive it.

2. Use the create method to perform token verification on the form to prevent repeated submission of the form.

3. The data can be automatically verified. The premise is that you must manually create a UserModel.class.php file in the Model folder and add verification responsibilities in it.

protected $_validate = array( array('username','require','用户名必须', 1), );

4. The data can be automatically verified. The field is automatically assigned a value. The prerequisite is that you must manually create a UserModel.class.php file in the Model folder and add

protected $_auto = array( array('create_time','time',self::MODEL_INSERT,'function'), );

to it. Then the user's registration time will be automatically assigned the current time.

After the settings are completed, you can write code in the corresponding method in the controller. When executing this sentence, $data = $goods->create() will automatically obtain each value of the form. Even if you want to add fields to the data table in the future, you only need to add the corresponding field names to the form, which can be said to be very convenient.

if(IS_POST){ $goods = M('goods'); if($data = $goods->create()){ if($goods->add($data)){ $this->success('添加成功','show_list','2'); }else{ $this->error('添加失败'); }}}

The create method is also special - it can remove fields that are not in the database from the array.

For example, if there is no aa field in your database, but there is in your form, the create method will filter it out when submitting the added data.
