Question

我的Laravel分页输出就像以前的laravel分页一样，但是我需要为每个对象更改数据数组。我的输出是：

如您所见，数据对象有2个项目，我需要更改。

我的代码是：

$items = $this->items()
        ->where('position', '=', null)
        ->paginate(15);

返回带有数据透视表的用户项目，但我不喜欢数据透视表在JSON中的显示方式，所以我决定更改项目，并在项目之前用枢轴组织每个项目。 / p>

为此，我尝试使用foreach

foreach ($items->data as $item)
        {

        }

这给我一个错误，原因我不知道：

Undefined property: Illuminate\Pagination\LengthAwarePaginator::$data"
status_code: 500

任何帮助？

Answer 1

paginator的项目是一个集合。您可以抓住它并转换数据，如下所示：

$paginator = $this->items()->where('position', '=', null)->paginate(15);
$paginator->getCollection()->transform(function ($value) {
    // Your code here

    return $value;
})

Answer 2

如果您想保留分页的项目：

    $itemsPaginated = $this->items()
         ->paginate(15);

    $itemsTransformed = $itemsPaginated
        ->getCollection()
        ->map(function($item) {
            return [
                'id' => $item->id,
            ];
    })->toArray();

    $itemsTransformedAndPaginated = new \Illuminate\Pagination\LengthAwarePaginator(
        $itemsTransformed,
        $itemsPaginated->total(),
        $itemsPaginated->perPage(),
        $itemsPaginated->currentPage(), [
            'path' => \Request::url(),
            'query' => [
                'page' => $itemsPaginated->currentPage()
            ]
        ]
    );

Answer 3

如果要更改或更新Laravel分页输出，但不影响分页，则应遵循以下说明。

$items = Model::paginate(10);

$updatedItems = $items->getCollection();

// data manipulation

// ...

$items->setCollection($updateItems);

您可以从here

进行检查

Answer 4

我可以做的更短一些。这将返回编辑后的$array而不是简单的$paginated。本示例修改文件名。 doc对我有用。

    $paginated=$query->paginate(12);
    $array=$paginated->toArray();
    foreach ($array['data'] as $r=>$record) {
        $array['data'][$r]->gif=$array['data'][$r]->gif.".gif";
    }
    return $array;

Answer 5

-Laravel 5.4

// example update column "photo" 
// from "/path/to/photo.png" 
// to "abc.com/path/to/photo.png"
foreach ($items as $item)
{
    $path = $item->photo;

  // Remove 
  $item->offsetUnset("photo");

  // Set
  $item->offsetSet("photo", url($path));
}

Answer 6

我遇到了同样的问题然后我发现了Eloquent mutators。

它们允许您在获取或设置数据时修改数据。

在我的示例中，我将HTML存储为Markdown，然后以HTML格式检索它你已经在你的问题中包含了很少的代码，所以我将为我的特定事件提供我自己的版本。此外，mutator代码放在模型中，而不是控制器。

use Illuminate\Mail\Markdown;
use Facades\League\HTMLToMarkdown\HtmlConverter as Markup;

class Post extends Model
{
    protected $fillable = [
        'title', 'body'
    ];

    /**
     * Convert to HTML when displaying on the screen.
     */
    public function getBodyAttribute($value)
    {
        return $this->attributes['body'] = Markdown::parse($value);
    }

    /**
     * Convert to Markdown when storing in the database.
     */
    public function setBodyAttribute($value)
    {
        return $this->attributes['body'] = Markup::convert($value);
    }
}

函数名称必须符合以下条件：

以小写字母get或set开头。
必须是PascalCase中的数据库列（或者Laravel引用它的StudlyCase;虽然我认为命名不正确。请参见此处：https://stackoverflow.com/a/32731818/3578036）。
最后，函数名称必须以Attribute结尾，并带有大写A。

getCollection

是获取物品的一种方法。另一种方法是使用这个例如，user没有name参数，只有first_name和last_name

$userPaginatedData = User::paginate(15);
$users = $userPaginatedData->items();

foreach($users as $user) {
   $user->name = $user->first_name . ' ' . $user->last_name;
}


return $userPaginatedData;

现在，在data键中，您将看到每个user都具有name参数。

注意 $models->setCollection(collect($franchiseData));你必须使用 collect() 否则你会得到错误。

Answer 9

事实上，$items是一个Paginator个实例，您可以将其删除：

foreach ($items as $item)
{

}

应该有用。

Answer 10

<?php 

$itemsPaginated = $this->items()->paginate(15);

$itemsPaginated = json_encode($itemsPaginated);

foreach ($itemsPaginated->data as $key => $item) {
    $results->data[$key]; //Modify
}

$itemsPaginated = json_encode($results);

Answer 11

忽略laravel中的分页并击中正常数据

foreach ($items as $item)
{

}

Answer 12

您必须在刀片中使用以下代码

{!! $items->render() !!}

Laravel更改分页数据
