从Laravel 5.8表单的复选框传递布尔值

Question

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。创建新的帖子并保存时，它会持久保存到数据库中，甚至可以更新它而不会出现问题。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。

Answer 1

您不清楚问题到底是什么，但是可以在模型中将属性强制转换为布尔值。

<?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。

<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。

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

Answer 2

尝试这个 $post->is_featured = $request->input('is_featured') ? true : false;
