如何在 Laravel 中调整图像大小并同时将数据保存在数据库中

Question

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

Answer 1

将文件名放入mysql而不是图像对象!!!!!!

$post->image = "images/$filename";
