从Laravel 5.8表单的复选框传递布尔值 [英] Passing a boolean value from checkbox in Laravel 5.8 form

问题描述

我尝试在创建新的帖子时保存布尔值，然后在更新帖子时让它更新值.当我创建一个新的帖子并保存时，它会持久保存到数据库中，甚至可以毫无问题地对其进行更新.我在处理复选框布尔值时遇到了一些麻烦.这是我在拉拉韦尔(Laravel)的拳头项目，这是我确定的障碍之一.

I am trying to save boolean value when I create a new Post and then have it update the value if I update the Post. When I create a new Post and save, it persists to the database and I can even update it without issue. I am just having a little trouble dealing with a checkbox boolean. This is my fist project in Laravel, which is part of my hurdle I'm sure.

模式

...
public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->increments('id');
            $table->unsignedBigInteger('user_id');
            $table->string('title');
            $table->text('body')->nullable();
            $table->string('photo')->nullable();
            $table->boolean('is_featured')->nullable()->default(false);
            $table->boolean('is_place')->nullable()->default(false);
            $table->string('tag')->nullable()->default(false);
            $table->timestamps();
        });

        Schema::table('posts', function (Blueprint $table) {
            $table->foreign('user_id')->references('id')->on('users');
        });
    }
...

PostController.php

...
public function store(Request $request)
    {
        $rules = [
            'title' => ['required', 'min:3'],
            'body' => ['required', 'min:5']
        ];
        $request->validate($rules);
        $user_id = Auth::id();
        $post = new Post();
        $post->user_id = $user_id;
        $post->is_featured = request('is_featured');
        $post->title = request('title');
        $post->body = request('body');
        $post->save();

        $posts = Post::all();
        return view('backend.auth.post.index', compact('posts'));
    }

<input type="checkbox" name="is_featured" class="switch-input"

推荐答案

您不清楚问题到底是什么，但是您可以

You're not very clear on what exactly the problem is, but you can cast the attribute as a boolean in the model.

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    protected $casts = [
        'is_featured' => 'boolean',
        'is_place' => 'boolean',
    ];
}

然后在表单中，您需要检查该值以确定是否选中了该框.

Then in your form you'll want to check that value to determine if the box is checked.

<input type="checkbox" name="is_featured" class="switch-input" value="1" {{ old('is_featured') ? 'checked="checked"' : '' }}/>

在您的控制器中，您只想检查输入是否已提交.未经检查的输入将不会被加总.

In your controller, you'll want to just check if the input is submitted. An unchecked input won't be sumitted at all.

$post->is_featured = $request->has('is_featured');
