在 Cakephp 中使用 Paginator 时出错答案

【问题标题】：Error when using Paginator in Cakephp在 Cakephp 中使用 Paginator 时出错
【发布时间】：2018-07-10 18:03:33
【问题描述】：

我有一个用于分页数据的变量 $paginator

在我的控制器中

public $paginator = [
    'limit'=>5,
    'order'=>[
        'author'=>'desc'
    ]
];

在我的视图模板（.ctp）中

<?= $this->Paginator->prev('<< pre') ?>
<?= $this->Paginator->next('next >>')?>
<?= $this->Paginator->counter() ?>

但我收到很多错误：

注意（8）：未定义索引：pageCount [CORE/src/View/Helper/PaginatorHelper.php，第 591 行] 注意（8）：未定义索引：count [CORE/src/View/Helper/PaginatorHelper.php, line 595] 注意（8）：未定义索引：perPage [CORE/src/View/Helper/PaginatorHelper.php，第 598 行] 注意（8）：未定义索引：count [CORE/src/View/Helper/PaginatorHelper.php, line 599] 注意（8）：未定义索引：count [CORE/src/View/Helper/PaginatorHelper.php, line 600] 注意（8）：未定义索引：页面[CORE/src/View/Helper/PaginatorHelper.php，第613行] 注意（8）：未定义索引：当前 [CORE/src/View/Helper/PaginatorHelper.php，第 615 行] 注意（8）：未定义索引：count [CORE/src/View/Helper/PaginatorHelper.php, line 616]

我知道只有这一行会导致错误

<?= $this->Paginator->counter() ?>

我无法分页。为什么会这样？ :(

显示该视图的整个控制器操作
哦。谢谢你。谢谢你，我在控制器中看到了我的失踪。我还没有声明分页 $paginate = $this->paginate($this->Articles); $this->set(compact('$paginate'));
我想是的 :)

【解决方案1】：

在控制器分页属性中

public $paginate = [
        'States' => ['scope' => 'states'],
        'Lgas' => ['scope' => 'lgas'],
];

在控制器动作中

  $lgas = $this->paginate($this->Lgas, ['scope' => 'lgas']);
  $states = $this->paginate($this->States, ['scope' => 'states']);
  $this->set(compact('lgas', 'states'));

在视图中

<div class="paginator">
        <ul class="pagination">
            <?=$this->Paginator->first('<< ' . __('first'), ['model' => 'Lgas', 'tab' => 'lga'])?>
            <?=$this->Paginator->prev('< ' . __('previous'), ['model' => 'Lgas', 'tab' => 'lga'])?>
            <?=$this->Paginator->numbers(['model' => 'Lgas', 'tab' => 'lga'])?>
            <?=$this->Paginator->next(__('next') . ' >', ['model' => 'Lgas', 'tab' => 'lga'])?>
            <?=$this->Paginator->last(__('last') . ' >>', ['model' => 'Lgas', 'tab' => 'lga'])?>
        </ul>
        <p><?=$this->Paginator->counter(['format' => __('Page {{page}} of {{pages}}, showing {{current}} record(s) out of {{count}} total'), 'model' => 'Lgas', 'tab' => 'lga'])?></p>
    </div>

    <div class="paginator">
        <ul class="pagination">
            <?=$this->Paginator->first('<< ' . __('first'), ['model' => 'States'])?>
            <?=$this->Paginator->prev('< ' . __('previous'), ['model' => 'States'])?>
            <?=$this->Paginator->numbers(['model' => 'States'])?>
            <?=$this->Paginator->next(__('next') . ' >', ['model' => 'States'])?>
            <?=$this->Paginator->last(__('last') . ' >>', ['model' => 'States'])?>
        </ul>
        <p><?=$this->Paginator->counter(['format' => __('Page {{page}} of {{pages}}, showing {{current}} record(s) out of {{count}} total'), 'model' => 'States'])?></p>
    </div>
