laravel 4组集合/结果

Question

我想通过循环中的'alpha'做一个简单的组，用于词汇表页面，但不知道如何实现这一点。我的数据是

阿尔法glossary_title

一个苹果乙香蕉苹果的另一！

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 

Answer 1

这将返回$glossary->alpha一个电邮宣传新的集合：

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

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

您将在视图中需要2个循环，然后首先针对组，其次针对每个组中的条目。
