php - Show the correct error validation messages -

i have page 2 forms on it: registration form , login form. each form has submit button. i'm validating both forms, example if press submit button of registration form i'd show error messages of registration form , not of login form. @ moment both error message being shown. there way around this?

<div class="grid-container">      <div class="grid-50 login">         <h3>inloggen</h3>         <?php              $loginemail = array('placeholder' => "email", 'name' => "loginemail");             $loginpassword = array('placeholder' => "wachtwoord", 'name' => "loginpassword");             $loginsubmit = array('name' => "loginsubmit", 'class' => "btn", 'value' => "inloggen");             $loginforgot = array('name' => "loginforgot", 'class' => "link", 'value' => "wachtwoord vergeten?");              echo form_open('login/inloggen', array('class' => 'grid-100 formc'));             echo form_input($loginemail);             echo form_password($loginpassword);             echo form_submit($loginsubmit);             echo form_submit($loginforgot);             echo form_close();         ?>         <?php echo validation_errors('<p class="error">');?>     </div>        <div class="grid-50 login">         <h3>registreren</h3>          <?php              $registername = array('placeholder' => "naam", 'name' => "registername");             $registeremail = array('placeholder' => "email", 'name' => "registeremail");             $registerpassword = array(  'placeholder' => "wachtwoord", 'name' => "registerpassword");       $registersubmit = array('name' => "registersubmit", 'class' => "btn", 'value' => "registreer");          echo form_open('login/register');         echo form_input($registername, set_value('registername'));         echo form_input($registeremail, set_value('registeremail'));         echo form_password($registerpassword);         echo form_submit($registersubmit);         echo form_close();     ?>      <?php echo validation_errors('<p class="error">');?> </div> 

validation in controller

$this->form_validation->set_rules('registeremail', 'email verkeerd', 'trim|required|valid_email');         $this->form_validation->set_rules('registerpassword', 'password te kort', 'trim|required|min_length[4]'); 

it nicer if create different rules login , you're registration.

how?

create form_validation.php file on application/libraries

inside specify rules you're login , register example

$config = array(   'login_validation_rules'=>array(         array(         'field' => 'username',         'label' => 'the user name',         'rules' => 'required'     ),         array(         'field' => 'password',         'label' => 'the password',         'rules' => 'required'     )     ),    'registration_validation_rules'=>array(         array(         'field' => 'email',         'label' => 'the email',         'rules' => 'required|valid_email'     ),         array(         'field' => 'firstname',         'label' => 'the firstname',         'rules' => 'required'     )    )  ); 

then on you're controller can catch form submitting , validation rules use example

if($this->input->post('registersubmit')) {   if($this->form_validation->run('registration_validation_rules') == false)   {    //error   }else{    //good   } }elseif($this->input->post('loginsubmit')){   if($this->form_validation->run('login_validation_rules') == false)   {    //error   }else{    //good   } } 

at same time you're controller not cluttered rules. makes reading easier can read more of on codigniter manual - validation config file
