"The upload path does not appear to be valid". Codeigniter file upload not working [closed]

Question

I have been stuck at this point for a long time and even after reading a number of posts, I haven't been able to find a solution.

I am making an interface for a quiz, and in the admin interface, I need to upload images to a folder and upload the image name to the database. I can handle to other things but the image upload is bugging me alot for a long time.

Please take a look at my code below.

The Form

<?php echo form_open_multipart('admin/update_question'); ?> <?php echo form_hidden('questionid', $question->level); ?> <?php echo form_label('Comment', 'comment'); ?> <div class="input"> <?php     $arr_comment = array(         'name'  => 'comment',         'id'    => 'comment',         'value' => $question->comment         );         echo form_textarea($arr_comment); ?> </div> <br/> <?php echo form_label('Answer', 'answer'); ?> <div class="input"> <?php     $arr_answer = array(             'name'  => 'answer',             'id'    => 'answer',             'size'  => '10000',             'value' => $question->answer     );     echo form_input($arr_answer); ?> </div> <br/> <?php echo form_label('Image', 'userfile'); ?> <div class="input"> <?php     $arr_image = array(         'name'  => 'userfile',         'id'  => 'userfile',         'value' => ''     );     echo form_upload($arr_image); ?> </div> <br/> <?php $arr_button = array(     'name'  => 'submit',     'value' => 'Update Question',     'class' => 'btn primary large'     ); ?> <div class="input"> <?php echo form_submit($arr_button); ?> </div> <br/> <?php echo form_close(); if ($error != '')     echo '<div class="alert-message error">'. $error.' </div>'; echo validation_errors(); ?> 

I have tried running a js which returns the filename in the upload box, and it does return it.

The Controller

public function update_question() {         $comment = $this->input->post('comment');         $answer = $this->input->post('answer');          echo var_dump(is_dir(base_url().'uploads/'));          /*          * Uploading image          */         $config['upload_path'] = base_url().'/uploads/';         $config['allowed_types'] = 'gif|jpg|png';         $config['max_width'] = 0;         $config['max_height'] = 0;         $config['max_size'] = 0;         $config['encrypt_name'] = TRUE;          $this->load->library('upload', $config);         if ( ! $this->upload->do_upload())         {                 $error = array('error' => $this->upload->display_errors());                 print_r($error);         }         else         {                 $arr_image = array('upload_data' => $this->upload->data());                 print_r($arr_image);         }          $questionid = $this->input->post('questionid');         $question_data = array(             'comment'   => $comment,             'answer'    => $answer         );         $this->load->model('adminmodel', 'admin');         $question_data = $this->admin->update_question_data($questionid, $question_data);         //redirect('admin/questions', 'location'); } 

For my upload path, I have tried a number or combinations and the only one which returned a TRUE value was var_dump(is_dir('/wamp/www/quark_edorado/uploads')); but this also returned the same error.

I do not know where I am going wrong.

Update

My directory structure is

/application/ /public/     css/     fonts/     images/     js/ /system/ /uploads/ 

I am operating a Windows machine and using WAMP. Does that make a difference?

Answer 1

I was autoloading the library and somehow when I was trying to initialize the configuration by $this->load->library('upload', $config); it wouldn't do so.

Instead I put my config files in config/upload.php

The other method to do so would have been $this->upload->initialize($config);
