thinkphp Automatic Validation Failure resolution

Copy CodeThe code is as follows:
/*
* Landing
*/
Public Function Login () {
if ($_post[' submit ']) {
$DB = D (' Login ');//Custom model processing
If inside is the automatic verification of the thinkphp.
if (! $DB->create ()) {
$this->redirect (' Index/login ', ', 3, ' Error message: '. $DB->geterror (). ' <br/> system will return in 3 seconds after landing ... ');
}else{
$con [' LoginName '] = $_post[' username '];
$con [' loginpwd '] = MD5 ($_post[' userpwd ']);
$list = $DB->where ($con)->find ();
if (count ($list) >0) {
echo ' OK ';
}else{
$this->redirect (' Index/login ', ', ', 3, ' Error message: Username or password error <br/> system will return in 3 seconds after landing ... ');
}
}
return;
}
This just encapsulates the address of the template file.
A (' Public ')->showpage (' login ');
}

Copy CodeThe code is as follows:
<?php
Class Loginmodel extends Model {
Setting up a data table
Protected $tableName = ' admin ';
Automatic Validation settings
Protected $_validate = Array (
Array (' username ', ' require ', ' username must be! ', 1),
Array (' userpwd ', ' require ', ' Password must be! ', 1),
);
/* Auto-fill if it is not automatically validated, uncomment this code to see.
Protected $_auto = Array (
Array (' status ', ' 1 ', Self::model_insert),
Array (' Create_time ', ' time ', Self::model_insert, ' function '),
);*/
/* Reference ThinkPHP2.0 Development Manual: thinkphp manual type checking is only for database-level validation, so the system also has built-in data object automatic validation to complete the business rule validation for the model, and in most cases the data object is created by the $_post data submitted by the form. Need to use the automatic verification function of the system, only need to define the $_validate property in the Model class
*/
/* It says here, just want to define the $_validate attribute in the model class, but in the use of ThinkPHP2.1, it does not pass the validation, $DB->geterror () No error reason to return, and refresh the time $db-> GetError () returns a "token form error"
