Original: thinkphp auto-Create data, auto-validate, auto-Complete Detailed example introduction (19)
1: Automatically create data
//$name =$_post[' name '];
//$password =$_post[' password '); ---The post value that this registration page passes over
The following uses the auto-dress Create method can not use this, will act bound
$user =m (' user ');
$User->create (); Will pass the $_post data to the field of the database
$user->add (); You can write directly to
2: Automatic verification(you only need to define the $_validate attribute within the Model class)
Use Step (register to validate user table)
A: Create user table Custom mode--->home\lib\model\usermodel.class.php
<?php
//Note: Code username password .... is the name value of your form, which corresponds to the
//The field name within the form defines the
class Usermodel extends model{
protected $_validate=array (
Array (' Code ', ' Require ', ' verification code must be filled in! '),
Array (' Code ', '
checkcode', ' captcha error! ', 0, ' callback ', 1),//Use callback function Checkcode
Array (' username ', ' require ', ' user must fill in! '),
Array (' username ', ' ', ' user already exists ', 0, ' unique ', 1),
Array (' username ', '/^\w{6,}$/', ' username must be 6 letters above ', 0, ' regex ', 1),
Array (' Repassword ', ' Password ', ' Confirm password incorrect ', 0, ' confirm '),
);
protected function
checkcode($code) {
if (MD5 ($code)!=$_session[' code ') {
return false;
}else{
return true;
}
}
}
?>
//Control please register the value corresponding method
<?php
class Registeraction extends action{
Public function Doreg () {
$user =d (' user '); The Big D method is to find your custom mode first (using the UserModel.class.php class created above)
//If there is a custom with custom, otherwise with the original D equivalent M m!=d
if (! $user->create ()) {//will automatically go to verify return a Boolean type, Success automatically creates data
$this->error ($user->geterror ());//Get specific error messages
}
$lastId = $user->add ();
if ($lastId) {
$this->redirect (' Index/index ');
}else{
$this->error (' User registration failed ');
}
}
}
?>
3: Auto-complete(example of making a message)
steps:
One: Create the message table Custom mode--->home\lib\model\messagemodel.class.php
<?php
class Messagemodel extends relationmodel{
protected $_auto=array (
Array (' Time ', ' time ', 1, ' function '),
Array (' uid ', '
getId', 1, ' callback ')
);
protected function
getId() {
return $_session[' id '];
}
}
?>
II: In the Controller
<?php
class Messageaction extends action{
Public function Doliuyan () {
$message =d (' message ');
//$message->time=time ();
//$message->uid=$_session[' id ']; These 2 values will be automatically populated in the custom Messagemodel complete
$message->add ();//return value is the new ID number
}
}
?>
