File upload using codeigniter Framework

pre-requesties

1)However create a uploads directory at the project root to store files.
2)After that, we need to prepare a simple form. It allow us to select the file.
3)In addition to that generate the controller for include file details.
4)Finally, create the model for database.

Step by step procedure:

The following steps are used to upload the file.

step1:

Create a directory name as ‘uploads’ And it should have the file permission of 777. Because, this is the most important step to allow permission on upload the file.

step 2:

Using a text editor, create a form and name it as fileview.php(application/views/). This will be used for rendering the html to user for allowing file upload functionality.

For example,

<html>
   <head>
      <title>My Form</title>
   </head>
   <body>
      <!-- <form action = ""> -->
      <?php echo $error;?>
      <?php echo form_open_multipart('Form/do_upload');?>
      <h5>firstname</h5>
      <input type = "text" name = "firstname" value="">
      <h5>gender</h5>
      <input type = "text" name = "gender" value="">  
      <h5>hobbies</h5>
      <input type = "text" name = "hobbies" value="">
      <h5>district</h5>
      <input type = "text" name = "district" value="">
      <h5>discription</h5>
      <input type = "text" name = "discription" value="">
      <h5>userfile</h5>
      <input type = "file" name = "userfile"  value="">
      

      </tr>  
      <?php
         echo form_close();
         ?>  
   </body>
</html>

step 3:

Instantly, create a controller file and also name it as Form.php
File name : (application/controllers/ Form.php).

public function upload_control() { 
          $this->load->library('form_validation');
         $this->load->view('fileview', array('error' => ' ' )); 
      } 

   public function do_upload() { 
      #Used to load the model
      $this->load->model('Insert_model');
       #Used to load the form validation library  
      $this->load->library('form_validation');
       #Used to load the upload library
       $this->load->library('upload');

          #used to get the file details
         $config['upload_path'] = './uploads/'; 
         $config['allowed_types'] = 'php|gif|jpg|png|txt|doc|docx'; 
         $config['max_size']      = '1000'; 
         $config['max_width']     = '1024'; 
         $config['max_height']    = '768';  
         
         $this->upload->initialize($config);

           #used to upload the file name in to the folder(uploads)

         if ( ! $this->upload->do_upload('userfile')) { 
              #$error used to display about error
            $error = array('error' => $this->upload->display_errors());
            $this->load->view('fileview', $error); 

         }
         else
          {         

           $data = array('upload_data' => $this->upload->data());
            $uploadData = $this->upload->data();
            #used to get the file name
            $userfile1 = $uploadData['file_name']; 
              
             $postData = array(
                'firstname' => $this->input->post('firstname'),
                'gender' => $this->input->post('gender'),
                  'hobbies' => $this->input->post('hobbies'),
                    'district' => $this->input->post('district'),
                      'discription' => $this->input->post('discription'),
                      'userfile' => $userfile1,
                      'discription' => $this->input->post('discription'),
                 ); 
                 # used to insert the values in to database 
              $insert = $this->Insert_model->insert($postData); 
          echo "Data inserted successfully";
           
            
         } 
        
         }
  • $this->load->model(‘Insert_model’); = Used to load the form model(database).
  • $this->load->library(‘form_validation’); = Used to load the form validation library.
  • $this->load->library(‘upload’); = Used to load the upload library for file upload.
  • $this->upload->do_upload(‘userfile’) =Used to upload the file name into the folder.
  • $error = array(‘error’ => $this->upload->display_errors()); = Used to diplay the error.
  • $this->load->view(‘fileview’, $error); = This will load the form with the error.

step4:

As a result of create a model, name it as Insert_model.php(application/controllers/ Insert_model.php).

<?php
class Insert_model extends CI_Model 
{
	public function insert($data = array()) 
	{
        $insert = $this->db->insert('form', $data);
    }
}
?>

conclusion:

Finally, The selected file name will show in the database and the file is uploaded to the folder with file name(uploads).
