Multiple file upload error

[eluser]EEssam[/eluser]
Hi,

The following code (http://ellislab.com/forums/viewthread/66017/) is not working for me:

Code:

function upload_images()
    {
        $config['upload_path'] = './system/application/uploads/images/';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '2048';
        $config['max_width'] = '0';
        $config['max_height'] = '0';

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

        $keys = array_keys($_FILES);
        $errors = array();
        $uploads = array();

        foreach ($keys as $field)
        {
            if (!$this->upload->do_upload($field))
            {
                $errors[] = $this->upload->display_errors();
            }
            else
            {
                $uploads = $this->upload->data();
            }
        }
    }

And I have the following in my view:

<?php echo form_upload('myimages[]') ?>
<?php echo form_upload('myimages[]') ?>
<?php echo form_upload('myimages[]') ?>
<?php echo form_upload('myimages[]') ?>

- The error message: You did not select a file to upload.
- I'm using form_open_multipart

Please help, what's wrong?

Thanks.

Don't you need to set up the arrays when using the form helpers?
like:

Code:

$data_file_1 = array(
   'name' => 'userfile_1',
   'id' => 'userfile_1',
   'size' => '50',
   'style' => 'width:50%',
);
$data_file_2 = array(
   'name' => 'userfile_2',
   'id' => 'userfile_2',
   'size' => '50',
   'style' => 'width:50%',
);
echo form_input($data_file_1);
echo form_input($data_file_2);

and so on ?

As far as i know, the usage of

Code:

myimages[]

Is just a shortcut of

Code:

push_array($destination_array, $new_data)

for example

Code:

$myimages[] = 'data_to_push_into_array_myimages';

But maybe I'm wrong and just are not familiar with the coding style you used!

I don't know how your view file looks in detail so it's hard to say
what could be missing ..

maybe you get that error because it is trying to uplaod fields you have left blank
from what i can tell your code doesn't account for fields that aren't filled
try putting
die(print_r($keys)); right after you declare that variable and see what you are actaully getting for data
