Question

我正在尝试使用ci上传图片。然而，在我正在进行图片处理空白屏幕之后。

我正在尝试上传660 KB图片。

控制器/ Cuploadfile.php

 //file upload function
function uploadgallerypic()
{
    //set preferences
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'jpg|gif';
    $config['max_size']    = '1000000';

    //load upload class library
    $this->load->library('upload', $config);
    $this->load->model('Mpages');


    if (!$this->upload->do_upload('filename'))
    {
        // case - failure
        $upload_error = array('error' => $this->upload->display_errors());
        $this->load->view('addpicture', $upload_error);
    }
    else
    {
        // case - success
        $gallery_id = $this->uri->segment(3);

        $upload_data = $this->upload->data();
        $filename = $upload_data['file_name'];
        $this->Mpages->add_picture_gallery($filename, $gallery_id);

        $data['success_msg'] = '<div class="alert alert-success text-center">Your file <strong>' . $upload_data['file_name'] . '</strong> was successfully uploaded!</div>';
        $this->load->view('addpicture', $data);
    }
}

我想知道为什么在我上传幻灯片图片后出现空白屏幕？

Answer 1

你能看到实际的图片进入uploads文件夹吗？您的错误显示设置是什么？

我的猜测是，您可能会在上传内容时遇到错误，但它不会向您显示错误是什么，因为它在加载视图之前发生。尝试检查这两个Stack Overflow文章，以便尝试：

此外，请确保服务器本身可以写入uploads目录。希望这有助于你的事业。
