Hello

This example doesn't want to work..
It keeps saying

Quote:The File field is required.

even if I removed the validation rule, it just show me the form again and again..

Am I missing something here ?

CI ver: 2.0.2

controller:

Code:
&lt;?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Test_files extends CI_Controller

{

    public function __construct()

    {

        parent::__construct();

    }

    public function index()

    {

        $this->load->library( 'form_validation' );

        $this->form_validation->set_rules( 'inp_file', 'File', 'required' );

        if( $this->form_validation->run() === FALSE )

        {

            $this->load->view( 'test_files' );

        }

        else

        {

            echo '<pre>', print_r( $_FILES, TRUE ), '</pre>';

        }

    }

}

view:

Code:
<!DOCTYPE html>

&lt;html lang="en"&gt;

&lt;head&gt;

    &lt;meta charset="utf-8"&gt;

&lt;/head&gt;

&lt;body&gt;

&lt;?=form_open_multipart( $this->uri->uri_string() );?&gt;

    <div id="infoMessage">&lt;?=validation_errors();?&gt;</div>

    &lt;?=form_label('File: ', 'inp_file') . form_upload('inp_file', '', 'id="inp_file"');?&gt;

    &lt;?=form_submit('submit', 'Upload');?&gt;

&lt;?=form_close(); ?&gt;

&lt;/body&gt;

&lt;/html&gt;

Thanks

You can't check for inputs with type="file" via the form validation library. It only validates what's in the $_POST array and file upload info will be in $_FILES.

Have a look at the file uploading class (http://ellislab.com/codeigniter/user-gui...ading.html) instead, maybe that'll help you.

You're right.. but as i said:

Quote:even if I removed the validation rule, it just show me the form again and again..

the upload class is great,.. but I just wonder why I can't use the form_validation library with <input type="file" /> ??

aw, thanks bro

To answer your first question: The test_files view is loaded everytime you submit the form because no validation rules = is not valid, meaning $this->form_validation->run() always returns FALSE.

To answer your second question: Because it doesn't support it Wink

The lib doesn't know what type of input the fields are you set the rules for. It loops through all the rules and checks $_POST for each field according to what rules you defined, e.g. trim|required|valid_email. Now in case of an input with type="file", it'll not appear in $_POST but rather in $_FILES (but the form validation lib doesn't check that one).

Some time back I read about an extended version of the form validation that actually works with file uploads, but I haven't used it yet. I'm still kickin' it old school by combining form validation with file uploading and works fine for me so far.

Right,..

You made me check the form_validation::run()

Code:
[....]

    function run($group = '')

    {

        // Do we even have any data to process?  Mm?

        if (count($_POST) == 0)

        {

            return FALSE;

        }

        // Does the _field_data array containing the validation rules exist?

        // If not, we look to see if they were assigned via a config file

        if (count($this->_field_data) == 0)

        {

            // No validation rules?  We're done...

            if (count($this->_config_rules) == 0)

            {

                return FALSE;

            }

            [....]
