Question

I looked for this in Google and different answers on stackoverflow. And probaly there is an good answer in them but still i don’t get how i can implent it in my own code.

I got my own public function to upload an image, but now i want it to be optional. At this moment someone needs to upload an file to pass the validation, how can i make this optional?

my function:

public function _do_upload_image()
{
    $config['upload_path'] = './company_images/';
    $config['allowed_types'] = 'jpg|jpeg|png';

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

    if (!$this->upload->do_upload())
    {
        $this->form_validation->set_message('_do_upload_image', $this->upload->display_errors());
    }
    else
    {
        $this->_upload_data = $this->upload->data();
    }

}

Thanks in advance

–edit–

For other people, the answer worked and i gave my file_name an other name when there was no image uploaded. It looks like this:

public function _do_upload_image()
{
    $config['upload_path'] = './company_images/';
    $config['allowed_types'] = 'jpg|jpeg|png';
    $returnArr = array();

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

    if (!$this->upload->do_upload())
    {
        $returnArr = array('file_name' => 'leeg.jpg');
    }
    else
    {
        $returnArr = $this->upload->data();
    }

    $this->_upload_data = $returnArr;
}

If you mean you need to make your upload function optional then you can just do:

public function _do_upload_image()
{
    $config['upload_path'] = './company_images/';
    $config['allowed_types'] = 'jpg|jpeg|png';
    $returnArr = array(); 

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

    if ($this->upload->do_upload())
    {
        $returnArr  = $this->upload->data();
    }
    return $returnArr; //just return the array, empty if no upload, file data if uploaded
}

Hope that makes sense
