HOW TO UPLOAD IMAGE IN CODEIGNITER STEP BY STEP

STEPS TO FOLLOW

• Create the assets folder/dir in the application folder/dir.
• Create uploads folder/dir in the assets folder/dir.

• Add enctype=”multipart/form-data” in your form tag.

"
base_url('user/create_profile');?>" method="post" enctype="multipart/form-data">

• Add “input type file” tag in the form

"

• copy the below function do upload in your control.

public function do_upload($input_name)
    {
        //todo:set unique name to file
        $date = new DateTime();
        $startdata = $date->format('YmdHis');
        $newName = str_replace('/', '', $startdata) . 1;
        $config['file_name'] = $newName;
        $config['upload_path'] = 'application/assets/uploads/';
        $config['allowed_types']        = 'gif|jpg|png';
//      $config['max_size']             = 2048;
//      $config['max_width']            = 1920;
//      $config['max_height']           = 1080;

        $this->load->library('upload', $config);

        if ( ! $this->upload->do_upload($input_name))
        {
            $error = array('error' => $this->upload->display_errors());
            return false;
        }
        else
        {
            $data = array('upload_data' => $this->upload->data());
            $image = $data['upload_data']['file_name'];
            return $image;
        }
    }

• Call your function in the post request where you are submitting your form

$image['image'] = $this->do_upload('image');

now in this the name “image” in $this->do_upload(‘image’); is the name of file form input tag as we set in form.

$image[‘image’] is the unique name of an image generated by the function you can view image in assets/uploads dir we create in 1st step and you insert the image name in the database.

Good luck guys, I will write the next tutorial on how to upload images and store name into database.
