Question

我有一个显示相关收入数组的视图。我在控制器中创建了一个集合来隔离我需要加在一起并显示为货币的两个变量。

public function view($id = null)
    {
        $annualOperatingBudget = $this->AnnualOperatingBudgets->get($id, [
            'contain' => ['Azinstitutions', 'BudgetExpenses', 'BudgetExpenses.ExpenseTitles', 'BudgetRevenues', 'BudgetRevenues.RevenueTitles']
        ]);
        $collection = new Collection($annualOperatingBudget->budget_revenues);
        $revenuesGroup1 = $collection->match(['revenue_title.revenue_group' => 1 ]);
        $revenuesGroup2 = $collection->match(['revenue_title.revenue_group' => 2 ]);
        $tuitionAndFees = $collection->match(['revenue_title.revenue_title' => 'Tuition and Fees']);
        $lessScholarshipAllowance = $collection->match(['revenue_title.revenue_title' => '- less Scholarship Allowance']);

        $this->set(compact('annualOperatingBudget', $annualOperatingBudget,'revenuesGroup1', 'revenuesGroup2', 'tuitionAndFees', 'lessScholarshipAllowance')); 
    }

我可以使用调试工具包查看变量：

annualOperatingBudget (array)
revenuesGroup1 (array)
revenuesGroup2 (array)
tuitionAndFees (array)
  4 (App\Model\Entity\BudgetRevenue)
     id 5
     annual_operating_budget_id 1
     revenue 1278
     revenue_title_id 5
     revenue_title (array)
lessScholarshipAllowance (array)
   5 (App\Model\Entity\BudgetRevenue)
     id 6
     annual_operating_budget_id 1
     revenue -257
     revenue_title_id 6
     revenue_title (array)

我想补充两个＆＃39;收入＆＃39;在一起

我试过了：

<?= $this->Number->currency(
     ($tuitionAndFees->revenue) + ($lessScholarShipAllowance->revenue), 
    'USD', ['places' => 1]) 
?>

但是我收到了几个错误：

Notice (8): Undefined property: Cake\Collection\Iterator\FilterIterator::$revenue [ROOT\plugins\Twit\src\Template\AnnualOperatingBudgets\view.ctp, line 49]
Notice (8): Undefined variable: lessScholarShipAllowance [ROOT\plugins\Twit\src\Template\AnnualOperatingBudgets\view.ctp, line 49]
Notice (8): Trying to get property of non-object [ROOT\plugins\Twit\src\Template\AnnualOperatingBudgets\view.ctp, line 49]

Answer 1

在尝试获取revenue属性之前，您必须迭代$ tuitionAndFees和$ lessScholarShipAllowance。像这样：

LoginPage

Answer 2

如果视图中所需的全部是所有学费和费用，您可以使用

$tuitionAndFees = $collection
    ->match(['revenue_title.revenue_title' => 'Tuition and Fees'])
    ->sumOf('revenue');

这将仅返回匹配项的总和。为$lessScholarShipAllowance执行类似操作，然后在您看来，只需

$this->Number->currency($tuitionAndFees + $lessScholarShipAllowance,
    'USD', ['places' => 1])

Cakephp 3：view.ctp求和两个变量
