Codeigniter multiple file upload

问题

In codeigniter 2 I have to do a multiple file upload.

In my view input elements looks like this

<input type="file" name="file[]" id="file_1" />
<input type="file" name="file[]" id="file_2" />
<input type="file" name="file[]" id="file_3" />
<input type="file" name="file[]" id="file_4" />
<input type="file" name="file[]" id="file_5" />
<input type="file" name="file[]" id="file_6" />

Plese help me how to write the controller to upload these files .. googled a lot .. Thanks in advance

回答1:

You can upload any number of files

$config['upload_path'] = 'upload/Main_category_product/';
$path=$config['upload_path'];
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '1024';
$config['max_width'] = '1920';
$config['max_height'] = '1280';
$this->load->library('upload', $config);

foreach ($_FILES as $key => $value) {

    if (!empty($value['tmp_name']) && $value['size'] > 0) {

        if (!$this->upload->do_upload($key)) {

            $errors = $this->upload->display_errors();
            flashMsg($errors);

        } else {
            // Code After Files Upload Success GOES HERE
        }
    }
}

And try using HTML like this:

<input type="file" name="file1" id="file_1" />
<input type="file" name="file2" id="file_2" />
<input type="file" name="file3" id="file_3" />
