Cakephp 3:视图。ctp两个变量之和

cakephp-3.0 sum

Ken · 技术社区 · 7 年前

我有一个视图显示了相关的收入阵列。我在控制器中创建了一个集合,以隔离需要添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)

我想把这两个‘收入’加在一起

我试过:

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

但我有几个错误:

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]

在尝试获取收入属性之前,您必须重复使用$TutionandFees和$LessCholarshipAssociation。类似这样:

foreach($tuitionAndFees as $tuitionAndFee){
    echo $tuitionAndFee->revenue
}

如果视图中所需的只是所有学费和费用的总和,则可以使用

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

这将只返回匹配项的总和。做类似的事情 $lessScholarShipAllowance ,然后在您看来

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