【中文标题】如何在 Laravel 中调整图像大小并同时将数据保存在数据库中【英文标题】：how to resize image in Laravel and save data in database at the same time 【发布时间】：2021-03-16 12:42:23 【问题描述】：我正在尝试将数据（标题、描述和调整大小的图像）传递到我的数据库
这是存储功能，现在它将我的图像保存在该路径中，但不会将它们保存在数据库中
如果我删除调整大小的图像，商店功能可以工作。
public function store(Request $request)
$request->validate([
'title' => 'required',
'image' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:10240',
'description' => 'required',
]);
$path = $request->file('image');
$filename = $path->getClientOriginalName();
$image_resize = Image::make($path->getRealPath());
$image_resize->resize(800, 800);
$image_resize->save(public_path('images/' .$filename));
$post = new Post;
$post->title = $request->title;
$post->description = $request->description;
$post->image = $image_resize;
$post->save();
return redirect()->route('posts.index')
->with('success','Post has been created successfully.');
enter image description here enter image description here
这是新的商店功能
public function store(Request $request)
$request->validate([
'title' => 'required',
'image' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:10240',
'description' => 'required',
]);
$path = $request->file('image');
$filename = $path->getClientOriginalName();
$image_resize = Image::make($path->getRealPath());
$image_resize->resize(800, 800);
$image_resize->save(public_path('images/' .$filename));
$post = new Post;
$post->title = $request->title;
$post->description = $request->description;
$post->image = 'images/' .$filename;
$post->save();
return redirect()->route('posts.index')
->with('success','Post has been created successfully.');
这是刀片代码

数据库中的“图像”列是哪种类型？ 【参考方案1】：将文件名放入mysql而不是图像对象!!!!!!
$post->image = "images/$filename";
【讨论】：
数据库中的图片类型是VARCHAR以上是关于如何在 Laravel 中调整图像大小并同时将数据保存在数据库中的主要内容，如果未能解决你的问题，请参考以下文章
