Question

我正在使用此功能上传多张图片。它在新的codeigniter设置中工作正常。但是当我在现有网站（codeigniter）中使用它时，它无法工作，也没有向我显示任何警告或错误。我没有得到我所缺少的东西。在调用函数$ this-＆gt; upload-＆gt; do_multi_upload（“uploadfile”）后，它没有显示任何内容。

  public function do_upload(){
    // Detect form submission.
    if($this->input->post('submit')){
        $path = './uni_images/';
        $this->load->library('upload');
        $this->upload->initialize(array(
            "upload_path"       =>  $path,
            "allowed_types"     =>  "gif|jpg|png",
            "max_size"          =>  '10000',
            "max_width"         =>  '1024000',
            "max_height"        =>  '7680000'
        ));
        if($this->upload->do_multi_upload("uploadfile")){
           echo "12";
            $data['upload_data'] = $this->upload->get_multi_upload_data();
            echo '<p class = "bg-success">' . count($data['upload_data']) . 'File(s) successfully uploaded.</p>';
        } else {   
        echo "13";
            // Output the errors
            $errors = array('error' => $this->upload->display_errors('<p class = "bg-danger">', '</p>'));              

            foreach($errors as $k => $error){
                echo $error;
            }
        }
    } else {
        echo '<p class = "bg-danger">An error occured, please try again later.</p>';
    }
    exit();
}

这是我的html代码，用于调用上面的函数

    <?php echo form_open_multipart('welcome_image/do_upload', array('class' => 'upload-image-form'));?>
        <input type="file" multiple = "multiple" accept = "image/*" class = "form-control" name="uploadfile[]" size="20" /><br />
        <input type="submit" name = "submit" value="Upload" class = "btn btn-primary" />
    </form>

尝试将ENVIRONMENT设置为development并在index.php中的根目录下添加ini_set('display_errors', 1);以显示错误。此外，请确保您的./uni_images/路径可写。

据我所知，do_multi_upload不是codeigniter上传库中的内置方法。 Here是通过扩展本机codeigniter上传库的第三方库。

希望它对你有用。

在codeigniter中无法使用多个文件上传
