                }
    }



} 
else{
$all_imgs = $this->session->userdata('image');
} 



   $this->db->insert('table_name', $all_imgs);

The problem I am facing in this code is Think suppose if I am adding 7 images, but it's showing only 5 images in database it's not taking more then five and also I want to know while editing the form if I don't want to change the image then it should remain same image so i have stored the old image in session and checking if it is empty then only it should session variable . But In my code if I will not upload new one If I keep old image as then it will save blank

You need to add an attribute multiple with input type file as <input type="file" name="img" multiple> — Harish

You should do all that php stuff the controller You have no form tags — user4419336

To avoid the offset error, inside of for loop you need to check if that array index is set or not: Here I have a demo code to upload multiple files in CodeIgniter:

views/stack_view.php

<?php if ($this->session->flashdata('status')) { ?>

    <h5><?=$this->session->flashdata('status')?>: <?=$this->session->flashdata('message')?></h5>

<?php } ?>

<?=form_open_multipart('stack', array('id' => 'my_id'))?>

  <input type="file" name="userfile[]" size="40" multiple/>
  <input type="submit" name="submit" value="Upload">

<?=form_close()?>

controllers/Stack.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Stack extends CI_Controller {

    public function __construct()
    {
            parent::__construct();

            $this->load->library('session');
            $this->load->helper(array('form', 'url'));
    }

    public function index()
    {
        if ($this->input->post('submit')) {

            $config['upload_path']          = './uploads/';
            $config['allowed_types']        = 'gif|jpg|png|jpeg';

            $files = $_FILES;

            if ($files['userfile']['name'][0] == '' ) {
                # code...
                $this->session->set_flashdata('status', 'error');
                $this->session->set_flashdata('message', "Select a file to upload");
            }
            else
            {
                $mum_files = count($files['userfile']);
                $dataInfo = array();
                for($i=0; $i<$mum_files; $i++)
                {

                    if ( isset($files['userfile']['name'][$i]) ) {

                        $config['file_name'] = time().'-'.$files['userfile']['name'][$i];
                        $this->load->library('upload', $config);

                        $_FILES['userfile']['name']= $files['userfile']['name']["$i"];
                        $_FILES['userfile']['type']= $files['userfile']['type']["$i"];
                        $_FILES['userfile']['tmp_name']= $files['userfile']['tmp_name']["$i"];
                        $_FILES['userfile']['error']= $files['userfile']['error']["$i"];
                        $_FILES['userfile']['size']= $files['userfile']['size']["$i"];    

                        $filename = rand().'-'.$_FILES['userfile']['name'];

                        if ( ! $this->upload->do_upload('userfile'))
                        {
                            $error_message = $this->upload->display_errors();

                            $this->session->set_flashdata('status', 'error');
                            $this->session->set_flashdata('message', "$error_message");
                        }
                        else
                        {
                            //$data = array('upload_data' => $this->upload->data());

                            $this->session->set_flashdata('status', 'success');
                            $this->session->set_flashdata('message', "Files upload is success");
                        }

                        $dataInfo[] = $this->upload->data(); //all the info about the uploaded files are stored in this array

                    }
                }

                //here you can insert all the info about uploaded file into database using $dataInfo
                $all_imgs = '';

                if ( count($dataInfo) > 0) {

                        $all_imgs .= $info['file_name'];
                        $all_imgs .= ',';
                    }
                }

                $insert_data = array(
                   'your_column_name' => rtrim($all_imgs,",")
                );

                $this->db->insert('your_table_name', $insert_data);
            }

        }

        $this->load->view('stack_view');

    }
}

Try this script and I hope you will get some help from this.

value is inserting twice but insert is outside the loop so it should insert only once. May be you are resubmitting the form twice?

Harish Over a year ago

@RoopaShree I checked and run the complete script on my system with database and its working perfectly fine, I don't know why are you getting this error without any logic, Have you really executed this code? Please if you really getting some error then comment with the proper error.

Harish Over a year ago

@RoopaShree Yes sure I'll but see your initial problem is resolved right so can you please accept this answer as accepted.

Roopa Shree Over a year ago

I have modified my code according to your code but the problem I am facing is if I will add more than 5 it will not take.I am not understanding why this happening

Roopa Shree Over a year ago

And I have taken stored value in session , if form is empty then it should take session value but It is not uploading can you please tell me how to do
