我有一个段落试图通过 bootstrap class 截断它text-truncate。在输出中我只得到一行。

<p class="text-truncate" style="max-width:300px;">
    Resize the browser window to see that its width (max-width) will change at different breakpoints.Resize the browser window to see that its width (max-width) will change at different breakpoints
</p>

获取输出

Resize the browser window to see that its wid...

期待输出

Resize the browser window to see that its width (max-width) 
will change at different breakpoints...

在内联CSS中我尝试过-webkit-line-clamp: 2，得到相同的结果。如何使用 bootstrap 获得多行text-truncate？

我正在尝试在 cakephp 版本 4 中上传文件。

我正在关注这个文档

我在控制器中尝试过

if ($this->request->is('post')) {

            $image = $this->request->getData('image');
            $fileName = $image->getClientFilename();

            $targetPath = WWW_ROOT.'img'.DS.$fileName;

            $image->moveTo($targetPath);

            $user = $this->Users->patchEntity($user, $this->request->getData());   //line 58

            $user->image = $fileName;

            $this->Users->save($user);
}

图片上传工作正常，名称也保存在数据库中。但是当发生验证错误时，我得到

Warning (4096): Object of class Laminas\Diactoros\UploadedFile could not be converted to string [CORE\src\Database\Type\StringType.php, line 97]
