Split results into 5 columns

问题

I have a query like:

$results = Post::all();

For the sake of simplicity, let's say the output is this (by id):

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15

My website has a 5-column layout. I need to split/divide these results into 5 columns such that it ends up like this:

 1 |  2 |  3 |  4 |  5
 6 |  7 |  8 |  9 | 10
11 | 12 | 13 | 14 | 15

The 5 column layout is split like this (the total number of columns is 25):

<div class="row">
    <div class="col-xs-5">
        //
    </div> 
    <div class="col-xs-5">
        //
    </div> 
    <div class="col-xs-5">
        //
    </div> 
    <div class="col-xs-5">
        //
    </div> 
    <div class="col-xs-5">
        //
    </div> 
</div>

How can I split $results up like this? Any way to make use of Laravel's Collection methods?

回答1:

Try this , i think it should give you the expected result

$chunks = $results->chunk(5);
 dd($chunks->toarray());

Laravel Docs

The chunk method breaks the collection into multiple, smaller collections of a given size

also it can be used in the View like this ( keep the same query in the controller and do the splitting in the View)

EDIT

             @foreach ($results->chunk(5) as $chunk)
                 <div class="row">
                      @foreach ($chunk as $test)
                   <div class="col-md-2">
                     {{ $test->id }}
                   </div>
                      @endforeach
                 </div>
              @endforeach

I think @AchrafKhouadja was right, you can use either array_chunk() or Collection chunk(), here is an example how to render it to be like what you've expected:

$cells = range(1, 25)
$rows  = array_chunk($cells, 5);

foreach ($rows as $row) {
    echo '<div class="row">';

    foreach ($row as $cell) {
        echo '<div class="col-xs-5">' . $cell . '</div>';
    }

    echo '</div>';
}

And the output would be:

<div class="row">
    <div class="col-xs-5">1</div>
    <div class="col-xs-5">2</div>
    <div class="col-xs-5">3</div>
    <div class="col-xs-5">4</div>
    <div class="col-xs-5">5</div>
</div>
<div class="row">
    <div class="col-xs-5">6</div>
    <div class="col-xs-5">7</div>
    <div class="col-xs-5">8</div>
    <div class="col-xs-5">9</div>
    <div class="col-xs-5">10</div>
</div>
<div class="row">
    <div class="col-xs-5">11</div>
    <div class="col-xs-5">12</div>
    <div class="col-xs-5">13</div>
    <div class="col-xs-5">14</div>
    <div class="col-xs-5">15</div>
</div>
<div class="row">
    <div class="col-xs-5">16</div>
    <div class="col-xs-5">17</div>
    <div class="col-xs-5">18</div>
    <div class="col-xs-5">19</div>
    <div class="col-xs-5">20</div>
</div>
<div class="row">
    <div class="col-xs-5">21</div>
    <div class="col-xs-5">22</div>
    <div class="col-xs-5">23</div>
    <div class="col-xs-5">24</div>
    <div class="col-xs-5">25</div>
</div>
