php - CodeIgniter not submitting form values to database -

setting "method" attribute of form fixed me, submitting database fine, now, have similar problem validating credentials maybe has same root problem since forgot method in first place, thank much.

i have problem while attempting learn codeigniter , general mvc principles.

i have sign form view

<div class="container"> <form class="form-horizontal" style="width:500px;" action="sign_up"> <fieldset>  <!-- form name --> <legend>sign up</legend>  <!-- text input--> <div class="control-group">   <label class="control-label" for="username">username</label>   <div class="controls">     <input id="username" name="username" placeholder="username" class="input-xlarge" required="" type="text">     <p class="help-block">your username</p>   </div> </div>  <!-- text input--> <div class="control-group">   <label class="control-label" for="email_address">email</label>   <div class="controls">     <input id="email_address" name="email_address" placeholder="email address " class="input-xlarge" required="" type="text">     <p class="help-block">enter email address</p>   </div> </div>  <!-- text input--> <div class="control-group">   <label class="control-label" for="first_name">first name</label>   <div class="controls">     <input id="first_name" name="first_name" placeholder="first name" class="input-xlarge" required="" type="text">     <p class="help-block">enter first name</p>   </div> </div>  <!-- text input--> <div class="control-group">   <label class="control-label" for="last_name">last name</label>   <div class="controls">     <input id="last_name" name="last_name" placeholder="last name" class="input-xlarge" type="text">     <p class="help-block">help</p>   </div> </div>  <!-- password input--> <div class="control-group">   <label class="control-label" for="password">password input</label>   <div class="controls">     <input id="password" name="password" placeholder="password" class="input-xlarge" required="" type="password">     <p class="help-block">help</p>   </div> </div>  <div class="control-group">   <label class="control-label" for="password">password confirmation</label>   <div class="controls">     <input id="password2" name="password2" placeholder="password" class="input-xlarge" required="" type="password">     <p class="help-block">help</p>   </div> </div>  <!-- button --> <div class="control-group">   <label class="control-label" for="singlebutton"></label>   <div class="controls">     <button class="btn btn-success" onclick="submit" >sign up</button>   </div> </div>  </fieldset> </form> </div> 

which submits (user/)sign_up

public function sign_up() {       $this->load->model('login_model');         if($query = $this->login_model->create_member()){             $data['main_content'] = 'user_login_view';             $this->load->view('template', $data);             }      } 

and passes model function "create_member"

function create_member()     {         $newdata = array(             'user_name' => $this->input->post('username'),             'password' => md5($this->input->post('password')),             'email' => $this->input->post('email_address'),             'first_name' => $this->input->post('first_name'),             'last_name' => $this->input->post('last_name')              );          $insert = $this->db->insert('users', $newdata);         return $insert;     } 

i believe have correct table set , following mvc principle.

id  int(11)          user_name   varchar(25)          password    varchar(32)          email   varchar(50)          first_name  varchar(32)          last_name   varchar(32) 

my problem password value passing on database rest submits 0, suggestions or obvious mistakes point out?

id      user_name   password                        email first_name last_name 20      0       d41d8cd98f00b204e9800998ecf8427e    0   0   0 

thank

i suggest change form open tag explicitly call controller, , need include method="post" attribute form post. e.g.

<form class="form-horizontal" style="width:500px;" action="/user/sign_up" method="post"> 

if wanted use ci's form helper, use following:

$attributes = array('class' => 'form-horizontal', 'style' => 'width:500px;');  echo form_open('user/sign_up', $attributes);
