Cakephp 3:从view.ctp中的关联表中获取foreach数组

Question

我正在看一张年度运营预算表。我有许多与单一年度经营预算有关的预算开支。我想把这些费用列在清单上。我该如何为这些做一个预测呢？

在我的AnnualOperatingBudgetController：

public function view($id = null)
    {
        $annualOperatingBudget = $this->AnnualOperatingBudgets->get($id, [
            'contain' => ['Azinstitutions', 'BudgetExpenses']
        ]);

        $this->set('annualOperatingBudget', $annualOperatingBudget );
    }

当我查看调试器中的变量时，我可以看到它们。

annualOperatingBudget (array)
id 2
azinstitutions_id 2
budget_year 2015
assumptions
budget_expenses (array)
0 (App\Model\Entity\BudgetExpense)
1 (App\Model\Entity\BudgetExpense)
2 (App\Model\Entity\BudgetExpense)
3 (App\Model\Entity\BudgetExpense)
4 (App\Model\Entity\BudgetExpense)
5 (App\Model\Entity\BudgetExpense)
azinstitution (array)
[new] (false)
[accessible] (array)
[dirty] (empty)
[original] (empty)
[virtual] (empty)
[errors] (empty)
[invalid] (empty)
[repository] AnnualOperatingBudgets

但我不能用

<?php foreach ($annualOperatingBudget as ?): ?>

只有一个。我如何到达与前驱相关的数组？

Answer 1

如果$annualOperatingBudget是一个数组，则可以使用以下方法访问费用：

<?php foreach ($annualOperatingBudget['budget_expenses'] as $expense): ?>

如果它是一个对象，那么使用以下方法访问它们：

<?php foreach ($annualOperatingBudget->budget_expenses as $expense): ?>
