Counting the number of uploaded files

Question

I am working on my CodeIgniter project, and it is so far working very well.

However, I need some way to count the number of uploaded files, since I want to limit it in some cases (but not all).

How can I do that? I tried count($_FILES) but that gave me nothing usable.

I also tried a bunch of other things, but neither gave me the information I need.

The upload form is a multiple file upload, and I am using this library to handle multiple uploads.

The upload function without the counting looks like this:

function do_upload()
{
    $setid = $this->input->post('imageset');
        $this->load->library('upload');
        $this->load->library('image_lib');
        $this->upload->initialize(array(
                "upload_path"   => "./photos/",
                "allowed_types" => "jpg|jpeg|png|gif",
                "encrypt_name" => TRUE
        ));
        try {
            $this->upload->do_multi_upload("files");
            $images = $this->upload->get_multi_upload_data();
            $config = array(
                    'image_library'  => 'gd2',
                    'create_thumb'   => TRUE,
                    'maintain_ratio' => TRUE,
                    'width'          => '145',
                    'height'         => '145'
            );
            foreach ($images as $image)
            {
                $config['source_image'] = $image['full_path'];
                $this->image_lib->initialize($config);
                $this->image_lib->resize();
                $this->manage_model->insertimage($image['file_name'],$image['orig_name'],$image['file_size'],$image['file_type'],$setid);
            }
            $this->session->set_flashdata('success','Billederne er nu blevet uploadet.');
        } catch (Exception $e) {
            $this->session->set_flashdata('error', $e);
        }
        redirect('manage/images','refresh');
}

Any help is very appreciated.

Solution

You can check the number of items in your $_FILES variable using for example:

$total = count($_FILES['your_variable_array_in_html']['tmp_name']);

You need to do that before the:

$this->upload->do_multi_upload("files");

line.

As you have already noticed, $_FILES only contains one variable - an array - containing arrays of the different sections, tmp_name, name, error, etc. Check the manual for more details.

@jeroen Any idea how to get the count of the number of files a user has actually uploaded. Right now, my form has 5 file fields, and using this method gives me 5 even when the user uploads only 2 files.
