Uplad file validation trouble

[eluser]Kurai[/eluser]
Hi!
I've got this upload function:

Code:

function upload()
    {
        $config['upload_path'] = './uploads/';
        $config['allowed_types'] = 'gif|jpg|png';
        //$config['max_size']    = '100';
        $config['max_width']  = '1024';
        $config['max_height']  = '768';
        
        $this->load->library('upload', $config);
    
        if ( ! $this->upload->do_upload())
        {
            $error = array('error' => $this->upload->display_errors());
            
            $this->load->view('backend/upload', $error);
        }    
        else
        {
            $data = array('upload_data' => $this->upload->data());
            
            $this->load->view('backend/uploadok', $data);
        }
    }

Now, I would like not to get the "you did not select a file to upload" error when I load the view for the first time. But I don't want two different functions as in the example provided in the user guide. How can I do it?

Thank you!

Try

Code:

if (!$_FILES)
{
    ...
}

Try changing it to this....

Code:

function upload()
    {
if ($this->input->post('submit'))
{
        $config['upload_path'] = './uploads/';
        $config['allowed_types'] = 'gif|jpg|png';
        //$config['max_size']    = '100';
        $config['max_width']  = '1024';
        $config['max_height']  = '768';
        
        $this->load->library('upload', $config);
    
        if ( ! $this->upload->do_upload())
        {
            $error = array('error' => $this->upload->display_errors());
            
            $this->load->view('backend/upload', $error);
        }    
        else
        {
            $data = array('upload_data' => $this->upload->data());
            
            $this->load->view('backend/uploadok', $data);
        }
}
else
{
$this->load->view('backend/upload');
}

This assumes that your submit button is:

Code:

<input type="submit" name="submit" value="something or other" />
