File upload validation

[eluser]mindesign[/eluser]
[quote author="pistolPete" date="1235453832"]Say we have a form which consists of a input field (called "image_title") and one file upload.
Both of them are required to pass the validation.

The rule looks like:

Code:

$this->form_validation->set_rules('image_title', 'Image title', 'trim|required|callback__do_upload');

Code:

// callback function to process the file upload and validate it
function _do_upload($file)
{
    $config['upload_path'] = './folder/';
    $config['allowed_types'] = 'put|your|allowed|types|here';
    $this->load->library('upload', $config);
        
    if ( ! $this->upload->do_upload())
    {
        // set the validation error using the errors provided by the upload class
        $this->form_validation->set_message('_do_upload', $this->upload->display_errors());
        return FALSE;
    }    
    else
    {
        return TRUE;
    }
}

Hey there. i'm trying to implement what you posted here but i'm running into problems....absolutely nothing happens, no errors, nothin.

I set my rule like so

Code:

$this->form_validation->set_rules('image', 'Image', 'required|callback__do_upload');

and your callback function like so. I added in 'image' into the do_upload thinking that might be the problem...but alas i guess it's not.

Code:

function _do_upload($file)
    {
        $config['upload_path'] = './public/images/temp_images/';
        $config['allowed_types'] = 'jpg|jpeg|png|gif';
        $this->load->library('upload', $config);
            
        if ( ! $this->upload->do_upload('image'))
        {
            // set the validation error using the errors provided by the upload class
            $this->form_validation->set_message('_do_upload', $this->upload->display_errors());
            return FALSE;
        }    
        else
        {
            return TRUE;
        }
    }

any help greatly appreciated!!
