cakePHP Validations : one model for to forms in the same view -

i have 1 view wich has 2 forms 1 login , 1 registration following : signup.ctp //my view

    <div>      <?php         echo $this->form->create("tbluser");         echo $this->form->hidden('formsent', array('value' => 'signup'));        echo $this->form->input('username' ,array('label'=>'username'));         echo $this->form->input('password' ,array('label'=>'password','type' => 'password'));         echo $this->form->input('email' ,array('label'=>'email'));        echo $this->form->end('register');      ?>      </div>  <div>  <?php      echo $this->form->create("tbluser");  ?>     echo $this->form->hidden('formsent', array('value' => 'login'));      echo $this->form->input('username' ,array('label'=>"username :"));     echo $this->form->input('password' ,array('label'=>"password :",'type' => 'password'));     echo $this->form->end('login');   ?> <div> 

the model i'm using both forms following :

<?php class tbluser extends appmodel{      public $validate = array(         'username'=>array(             array(                 'rule'=>'alphanumeric',                 'allowempty'=>false,                 'message'=>'invalide username!'             ),             array(                 'rule' => array('minlength', '4'),                 'message' => 'username has more 3 chars'             ),             array(                 'rule'=>'isunique',                 'message'=>'username taken!'             )         ),         'password' => array(                 array(                     'rule' => 'alphanumeric',                     'allowempty'=>false,                     'message' => 'password must alphanumeric!'                 ),                 array(                     'rule' => array('minlength', '4'),                     'message' => 'username has more 3 chars'                 )             ),         'email'=>array(             array(                 'rule'=>array('email',true),                 'required'=>true,                 'allowempty'=>false,                 'message'=>'invalide email adress!'             ),             array(                 'rule'=>'isunique',                 'message'=>'mail adress taken!'             )         )     ); } ?> 

the controller i'm using following :

<?php class tbluserscontroller extends appcontroller {     public $uses = array(         'tbluser'     );      public function signup()     {       if ($this->request->is('post')) {             if ('signup' === $this->request->data['tbluser']['formsent']) {                          // registration part.                 }else if('login' === $this->request->data['tbluser']['formsent']){                          //login part                 }     } } ?> 

my appcontroller looks :

<?php class appcontroller extends controller {     public $helpers = array('form', 'html');     public $components = array('session','cookie','auth'=>array(         'authenticate'=>array(              'form' => array(                 'usermodel' => 'tblforumuser',                 'fields' => array(                     'username' => 'username',                     'password' => 'password'                 )             )         )     )); } ?> 

right if fill wrong data signup form , submit validation occurs in login form fields how can set validation apply signup form , not both forms? thanks.

it looks validation being invoked on every read , write because telling model run validation without restriction. better way handle separate model each form.

by creating 2 new models userlogin , userregister extend tbluser, can set specific validation rules each form. :

view/tbluser/signup.ctp

<div>  <?php     echo $this->form->create("userregister");     echo $this->form->hidden('formsent', array('value' => 'signup'));    echo $this->form->input('username' ,array('label'=>'username'));     echo $this->form->input('password' ,array('label'=>'password','type' => 'password'));     echo $this->form->input('email' ,array('label'=>'email'));    echo $this->form->end('register');  ?>  </div>  <div>  <?php      echo $this->form->create("userlogin");  ?>     echo $this->form->hidden('formsent', array('value' => 'login'));      echo $this->form->input('username' ,array('label'=>"username :"));     echo $this->form->input('password' ,array('label'=>"password :",'type' => 'password'));     echo $this->form->end('login');   ?> <div> 

here, since we're using 2 separate models each $this->form-create(); helper, validation in specified model run. models contain validation applies form assigned it:

model/userregister.php

class userregister extends tbluser{     public $validate = array(         'username'=>array(             array(                 'rule'=>'alphanumeric',                 'allowempty'=>false,                 'message'=>'invalide username!'             ),             array(                 'rule' => array('minlength', '4'),                 'message' => 'username has more 3 chars'             ),             array(                 'rule'=>'isunique',                 'message'=>'username taken!'             )         ),         'password' => array(                 array(                     'rule' => 'alphanumeric',                     'allowempty'=>false,                     'message' => 'password must alphanumeric!'                 ),                 array(                     'rule' => array('minlength', '4'),                     'message' => 'username has more 3 chars'                 )             ),         'email'=>array(             array(                 'rule'=>array('email',true),                 'required'=>true,                 'allowempty'=>false,                 'message'=>'invalide email adress!'             ),             array(                 'rule'=>'isunique',                 'message'=>'mail adress taken!'             )         )     ); } 

model/userlogin.php

class userlogin extends tbluser{     public $validate = array(         'username'=>array(             array(                 'rule'=>'alphanumeric',                 'allowempty'=>false,                 'message'=>'invalide username!'             ),             array(                 'rule' => array('minlength', '4'),                 'message' => 'username has more 3 chars'             ),             array(                 'rule'=>'isunique',                 'message'=>'username taken!'             )         ),         'password' => array(             array(                 'rule' => 'alphanumeric',                 'allowempty'=>false,                 'message' => 'password must alphanumeric!'             ),             array(                 'rule' => array('minlength', '4'),                 'message' => 'username has more 3 chars'             )         )     ); } 

then in signup(); method, want load 2 new models created accordingly:

controller/tbluserscontroller.php

class tbluserscontroller extends appcontroller {     public $uses = array(         'tblforumuser'     );      public function signup() {       $this->loadmodel('userlogin');       $this->loadmodel('userregistration');        if ($this->request->is('post')) {             if ('signup' === $this->request->data['tblforumuser']['formsent']) {                          // registration part.                 }else if('login' === $this->request->data['tblforumuser']['formsent']){                          //login part                 }     } } 

hope helps
