php - codeigniter validation not working in bootsrap modal window -

i trying validation class working in codeigniter within bootstrap modal window. function in controller contains codes not being seen form-open function.

this modal form:

<div class="modal fade" id="login" tabindex="-1" aria-labelledby="modallabel" aria-hidden="true">   <div class="modal-dialog">     <div class="modal-content">       <div class="modal-header">         <button type="button" class="close" data-dismiss="modal" aria-hidden="true"></button>         <h4 class="modal-title" id="mymodallabel">login</h4>       </div>       <div class="modal-body">         <?php echo validation_errors();?>         <?php echo form_open('site/login_validation');?>         <form>           <div class="input-group">             <span class="input-group-addon"></span>             <input type="text" name="email" class="form-control" placeholder="email">           </div></br>           <div class="input-group">             <span class="input-group-addon"></span>             <input type="text" name="password" class="form-control" placeholder="password">           </div></br>           <button type="button" class="btn btn-default" data-dismiss="modal">close</button>           <button type="submit" value="login" class="btn btn-primary">login</button>           </br>         </form>         <?php echo form_close();?>         <div class="modal-footer">           <a href="#" >forgot password</a>         </div>       </div>     </div>   </div> </div>   

this form in controller:

public function login_validation(){     $this->load->helper(array('form','url'));     $this->load->library('form_validation');     $this->form_validation->set_rules('email','','required');     $this->form_validation->set_rules('password','','required');      if ($this->form_validation->run() == false){         $this->load->view('view_index');     }else {         redirect('site/view_member');                    } } 

as jcorry pointed out, you're duplicating <form> , </form> tags. if you're using form_open() , form_close(), don't need include them in view html.

from codeigniter docs:

form_open() creates opening form tag base url built config preferences

form_close() produces closing tag.

i suspect incorrect nesting confusing browser, trying close tags itself. if view source might see like:

<form action="site/login_validation"> </form><!-- closing tag added automatically browser --> <form>     <!-- form fields ... --> </form> </form> 

the second <form> element, contains fields, has no action, isn't talking controller when hit submit. delete <form> , </form> in html , let know how goes.
