Question

I’m doing a script that will upload an image and save the image path in the database. The only problem that I have is if a user doesn’t upload an image I want to set a default image.

But in codeigniter when an image is not selected it automatically gives an error saying that the input file hasn’t been selected.

my controller

  if ( !$this->upload->do_upload('image'))
     {
    $error = array('error' => $this->upload->display_errors());
    $this->load->view('upload_success', $error);

     }
    else {
        $image_data=array('image_info' => $this->upload->data('image')); 
        $image_path=$image_data['image_info']['full_path'];

        $data =array(
        'submitedby'=>$username,
        'city'=>$this->input->post('towncity'),
        'image' => $image_path

);  
   }

Can someone please suggest me how to set a default image if the user hasn’t selected an image without displaying the default error?

In the clause where do_upload() fails, check to see if the file was uploaded.

if (!$this->upload->do_upload('image')) {

    if (!empty($_FILES['image']['name'])) {
        // Name isn't empty so a file must have been selected
        $error = array('error' => $this->upload->display_errors());
        $this->load->view('upload_success', $error);
    } else {
        // No file selected - set default image
        $data = array(
            'submitedby' => $username,
            'city'       => $this->input->post('towncity'),
            'image'      => 'path/to/default/image',
        );
    }

} else {
    $image_data = array('image_info' => $this->upload->data('image'));
    $image_path = $image_data['image_info']['full_path'];

    $data = array(
        'submitedby' => $username,
        'city'       => $this->input->post('towncity'),
        'image'      => $image_path,
    );
}

This could be refactored further but the point is that you can check $_FILES['field_name']['name'] to see if a file was selected.
