Cakephp 3：从 view.ctp 中的关联 table 获取 foreach 数组

Question

我正在查看 table 年度运营预算。我有许多与单个年度运营预算相关的预算支出。我想在视图中列出这些费用。我如何为这些做一个 foreach 语句？

在我的 AnnualOperatingBudgetController 中：

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

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

当我查看 debugkit 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

但是我不会用

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

只有一个。如何到达 foreach 的关联数组？

Answer 1

如果 $annualOperatingBudget 是一个数组，您可以通过以下方式访问费用：

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

如果它是一个对象，那么访问它们：

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