php - Unable to access data in view codeigniter -


i have 3 controller methods name blog, load_messages , load_comments. want pull comments when user clicks on button. post id passed method name load_comments if load view named blog gives error because have passed data view. want pass data is comments controller.

the functions are:

public function blog() {      $user_session_email = $this -> session -> userdata('user_email','name','id');     if(!$user_session_email) {         redirect('/');     }       $user_data = $this -> users_model -> myaccount([         'id' => $this -> session -> userdata('id'),         'name' => $this -> session -> userdata('name'),         'email' => $this -> session -> userdata('user_email'),     ]);     $data["persoanl"] = $user_data;      $returned_result = $this -> users_model -> load_messages();     $messages["message"] = $returned_result['message'];      $this -> load -> view('users/inc/header', $data);     $this -> load -> view('users/inc/blog_form', $data);     $this -> load -> view('users/blog', $messages);     $this -> load -> view('users/inc/footer'); }  public function load_messages() {     $returned_result = $this -> users_model -> load_messages();     $messages["message"] = $returned_result["message"];     $messages['id'] = $this -> load_comments();     $this -> load -> view('users/blog', $messages); }  public function load_comments() {     $messages['id'] = $this -> input -> post('post_id');     $this -> load -> view('users/blog', $messages); }

in last method want pass $message variable, when pass value other functions in blog view loaded different parameters $messages['message'], generates error says $message undefined on blog view page if remove last method work perfectly. should how pass data blog?

blog view code

            <?php              foreach($message $blog) :         ?>         <div class="row blog_post<?php echo $blog -> blog_id; ?>" id="blog_posts">              <div class="col-lg-1 col-md-2 col-sm-2 col-xs-3 user_blog_image">                 <?php if($blog -> profile_image == null) { ?>                     <img src="<?php echo base_url(); ?>public/dist/img/user2-160x160.jpg" alt="user image">                 <?php } else { ?>                     <img src="<?php echo base_url().$blog -> profile_image; ?>"  alt="user image">                 <?php } ?>             </div> <!-- end of user blog image -->              <div class="col-lg-11 col-md-10 col-sm-10 col-xs-9 post_message">                 <?php if($blog -> id == $this -> session -> userdata('id')) : ?>                 <a class="pull-right" onclick="delete_post('<?php echo $blog -> blog_id; ?>', '<?php echo base_url('users/delete_post'); ?>')">                     &times;                 </a>                 <?php endif; ?>                  <p>                      <?php echo $blog -> message; ?>                  </p>                 <span class="pull-left">                      <small> posted by: <?php echo $blog -> name; ?></small>                  </span>                 <a onclick="get_comments(this.id, '<?php echo base_url('users/load_comments'); ?>')" class="stop_interval" id="<?php echo $blog -> blog_id; ?>">                      <i class='fa fa-comment' aria-hidden='true'></i> view comments                 </a>                 <a onclick="update_like('<?php echo $blog -> blog_id; ?>', '<?php echo base_url('users/update_like'); ?>')">                     <i class='fa fa-thumbs-up' aria-hidden='true'></i> likes (<small><?php echo $blog -> likes; ?></small>)                 </a>              </div> <!-- end of post message -->              <div class="col-lg-offset-1 col-lg-11 comment_field">                  <div class="show_comments col-lg-12 col-md-12 col-sm-12 col-xs-12" id="show_comments<?php echo $blog -> blog_id; ?>">                     <?php echo $id; ?>                     <div class="col-lg-1 col-md-1 col-sm-1 col-xs-1 commentor_pic">                         <img src="<?php echo base_url(); ?>public/dist/img/user2-160x160.jpg" alt="user image">                     </div> <!-- end of commentor picture -->                     <div class="col-lg-11 col-md-11 col-sm-11 col-xs-11 comment">                         <p> lorem ipsum dummy text of printing , typesetting industry. lorem ipsum has been industry's standard dummy text ever since 1500s, when unknown printer took galley of type , scrambled make type specimen book. </p>                         <p> <small> posted by: rashid khokhar </small> </p>                     </div> <!-- end of commentor picture -->                 </div> <!-- end of show comments -->                   <form method="post" id="comment_form<?php echo $blog -> blog_id; ?>">                     <input type="text" id="blog_comment<?php echo $blog -> blog_id; ?>" required name="comment_field" class="form-control" placeholder="type comment">                     <button type="submit" id="cmntbtn<?php echo $blog -> blog_id; ?>" class="btn btn-primary"><i class="fa fa-share" aria-hidden="true"></i></button>                 </form>             </div> <!-- end of comment field -->          </div>         <script type="text/javascript" src="<?php echo base_url('public/dist/js/jquery.js'); ?>"></script>         <script type="text/javascript" src="<?php echo base_url(); ?>public/dist/js/custom.js"></script>         <script type="text/javascript">             comment_blog('<?php echo $blog -> blog_id; ?>', '<?php echo base_url('users/comment_blog'); ?>');             jquery( "#show_comments<?php echo $blog -> blog_id; ?>" ).each(function( value ) {                 jquery(this).hide();             });         </script>          <?php endforeach; ?>     </div>  </div>

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
