在 laravel 的 td 元素中使用多个 for 循环

Question

大家好，我有 3 个雄辩的表成员，即承诺和活动，它们之间有关系，即： 对于成员模型

 protected $table = "members";

public function loans()
{
    return $this->hasMany(Loan::class, 'borrower_id', 'id');
}

public function user()
{
    return $this->hasOne(User::class, 'id', 'user_id');
}

public function pledges()
{
    return $this->hasMany(Pledge::class, 'member_id', 'id');
}

用于广告系列

    protected $table = "campaigns";

    public function pledges()
    {
        return $this->hasMany(Pledge::class, 'campaign_id', 'id')->orderBy('created_at', 'desc');
    }
}

那么对于质押模型

protected $table = "pledges";

    public function campaign()
    {
        return $this->hasOne(Campaign::class, 'id', 'campaign_id');
    }


    public function member()
    {
        return $this->hasOne(Member::class, 'id', 'member_id');
    }
}

在 plegde.create.blade 中

<div class="control-group">
                                     <label class="control-label">Member</label>
                  <div class="controls">
                    <select>
                       @foreach ($member as $members)
                        <option>{{ $members->first_name }}</option>
                        @endforeach
                    </select>

            <div class="control-group">

                  </div>
                </div>

              <div class="control-group">
                <label class="control-label">Amount</label>
                <div class="controls">

然后在我的承诺.index.blade.php 我有这个但它没有正确显示这是代码

<div class="widget-content nopadding">
        <table class="table table-bordered data-table">
          <thead>

任何帮助将不胜感激。

Answer 1

这不是一个好的解决方案。相同的表，不同的模型，不同的 foreachs。 你可以只做一个 foreach 和 function。像这样：

public function memberFunction()
{
    return $this->hasOne('App\Member');
}

//

 public function campaignFunction()
{
    return $this->hasOne('App\Campaign');
}

我们将连接作为一个函数。现在在 foreach 中使用带有 [' '] 标签的函数。

@foreach ($example as $examples)
<td>{{ $examples->memberFunction['firstname'] }}</td>
<td> {{ $examples->campaignFunction['name'] }} </td>
@endforeach

你可以这样继续。
