CodeIgniter图片上传-无法获得错误消息以显示

问题描述

| 这是我的上传模型

    function upload_avatar()
    {
        $id = $this->tank_auth->get_user_id();

        //config upload parameters and upload image
        $config = array(
            \'allowed_types\' => \'jpeg|jpg|png\',\'upload_path\' => $this->upload_path,\'max_size\' => 2048,\'encrypt_name\' => TRUE,\'overwrite\' => FALSE,);
        $this->load->library(\'upload\',$config);
        $this->upload->do_upload();

        //get upload data,config,resize uploaded image,save in avatars subfolder
        $image_data = $this->upload->data();

        if ($image_data[\'file_size\'] < 2048) {

            $config = array(
                \'source_image\' => $image_data[\'full_path\'],\'new_image\' => $this->upload_path . \'/avatars\',\'maintain_ratio\' => TRUE,\'width\' => 125,\'height\' => 125
            );
            $this->load->library(\'image_lib\',$config);
            $this->image_lib->resize();

            //only burn avatar path to user_profiles table if no upload errors
            if (!$this->upload->display_errors()) {
                $data = array(\'avatar\' => base_url() . \'images/avatars/\' . $image_data[\'file_name\']);
                $this->db->where(\'id\',$id);
                $this->db->update(\'user_profiles\',$data);
            }

            //delete the original file from server
            $this->load->helper(\'file\');
            unlink($image_data[\'full_path\']);

        } else {

    echo $this->upload->display_errors();

        }
    }

尝试上传大于2MB的文件时，我无法收到错误消息直接向浏览器回显。 公平地说，CI会忽略此大文件，并且当文件<2MB时正确上传。 唯一的是，我无法获得错误消息以显示在前端以向suer提供一些反馈。 有什么主意吗？

解决方法

$config[\'upload_path\'] = \'uploads/category/\'.$id.\'/\';
        //echo $file_name;die;
        //echo $config[\'upload_path\'];
        $config[\'allowed_types\'] = \'gif|jpg|jpeg|png\';
        $config[\'max_size\'] = \'2048\';
        $config[\'max_width\'] = \'1920\';
        $config[\'max_height\'] = \'1280\';
        $this->load->library(\'upload\');
         foreach ($_FILES as $key => $value) {
            //print_r($key);

            if (!empty($key[\'name\'])) {

                $this->upload->initialize($config);
                if (!$this->upload->do_upload($key)) {
                  // echo \'test\';die;
//                    rmdir(\'uploads/category/\'.$id);
                    $errors = $this->upload->display_errors();
                    flashMsg($errors);
                }
}
}

尝试这个！！,您的

post_max_size

限额是否少于2MB？ （http://ca3.php.net/manual/zh/ini.core.php#ini.post-max-size）如果这样，则在调用代码之前，该文件可能已被丢弃。 更新： 如果您在else块中取出函数调用，然后放入exit（\'too big \'）;那你能看到错误吗？如果是这样，可能是您如何取消通话。
