Question

我试图在我的循环中通过'alpha'做一个简单的组，用于词汇表页面但不确定如何实现这一点。我的数据是

alpha glossary_title

Apple B Banana另一个Apple！

GlossaryController.php

public function index() {

  $glossary = Glossary::groupBy('alpha')->orderBy('glossary_title', 'asc')->get();
  return View::make('glossary')->with('glossary', $glossary);

}

迁移

Schema::create('glossary', function(Blueprint $table)
        {
             // columns
            $table->increments('id');
            $table->string('glossary_title');
            $table->text('glossary_desc')->nullable();
            $table->char('alpha', 1);
            $table->timestamps();
        });

glossary.blade.php

@foreach($glossary as $glossary)
        <li>{{ $glossary->glossary_title}} <br /> {{ $glossary->glossary_desc}}</li>
@endforeach

这将返回按$glossary->alpha分组的新收藏：

$glossary = Glossary::orderBy('glossary_title', 'asc')->get();
$glossary = $glossary->groupBy('alpha');

// same as this:
$glossary = $glossary->groupBy(function ($entry) {
  return $entry->alpha;
});

您的视图中需要2个循环，首先是组，第二个是每组中的条目。
