Question

我一直试图解决这个问题好几天了。如果可能，请协助或建议其他方法。我可以为chrome，safari和firefox中的每个学生显示10个课程的总分。但是，我在IE9 / 10中收到此错误“此页面无法显示”。

我厌倦了调试并发现IE9 / 10在我通过requestAction使用for循环时显示上述错误。话虽如此，我会要求requestAction获得总分。

要获得总得分，我依赖于每个循环（foreach（$ customers as $ customer）{...}）来获得每个$ customer ['Customer'] ['id']并将其传递给requestAction并返回分数结果。

QNS 1.还有另一种方法可以实现这一结果吗？

QNS 2.我可以在控制器中执行所有操作吗？如果是这样，怎么样？

CONTROLLER

function eachlesson($lessonid, $sessionkey, $customer_id) {

return $this->Score->find('first', array('conditions' => array('Score.test_bk_session_id' => $sessionkey, 'Customer.customers_types' => 'student', 'Score.lesson' => $lessonid, 'Score.customer_id' => $customer_id)));

}

查看

<table>
<?php foreach ($customers as $customer) { ?>
<tr>
   <td>
      <?php echo $customer['Customer']['customers_name']; ?>
   </td>
   <td>
   <?php 
   $customer_id = $customer['Customer']['id'];
   $sessionkey = $this->params['pass'][1];

   //LOOP THROUGH 10 TIMES TO GET LESSON 1 - 10 SCORES
   for ($i=1; $i<=10; $i++) { 
       $lessonid = $i;
       $score = $this->requestAction('/scores/eachlesson/'.$lessonid."/".$sessionkey."/".$customer_id);


   //GETTING THE TOTAL SCORE FOR LESSON 1 TO 10
   (int)${'totaleachlesson'.$i} = $score['Score']['BI_pts'] + $score['Score']['FD_pts'] + $score['Score']['PO_pts']  + $score['Score']['WW_pts'] + $score['Score']['MG_pts'] + $score['Score']['FO_pts'];

   }

    //ADDING THE TOTAL SCORE OF THE 10 LESSONS
   $figureofcorrecttotal = $totaleachlesson1 + $totaleachlesson2 + $totaleachlesson3 + $totaleachlesson4 + $totaleachlesson5 + $totaleachlesson6 + $totaleachlesson7 + $totaleachlesson8 + $totaleachlesson9 + $totaleachlesson10;

   //DISPLAY THE TOTAL SCORE
   echo $figureofcorrecttotal;

Answer 1

首先，你为什么“拥有”才能使用requestAction？您根本不遵循蛋糕约定。您需要花一点时间阅读文档... Imo，您希望将“Score”模型与“Customer”模型相关联，并将两者合二为一。

<?php
// Customer model.

class Customer extends AppModel {
    var $name = 'Customer';

    var $hasMany = array(
        'Score' => array(
            'className' => 'Score',
            'foreignKey' => 'customer_id',
            'limit' => 10,
            'conditions' => array(
                '<conditions go here>'
            )
        )
    );
}

?>

<?php
// Score model.

class Score extends AppModel {
    var $name = 'Score';

    var $belongsTo = array(
        'Customer' => array(
            'className' => 'Customer',
            'foreignKey' => 'customer_id' // This assumes you have a customer_id field in the 'scores' table.
        )
    );
}

?>

现在模型是关联的，如果你没有附加可包含的行为，你可以在每个模型或主app_controller.php中添加：

var $actsAs = array('Containable');

现在，您需要做的就是在Customer模型上执行查找时包含Score模型，并且将自动为您检索10个Scores。

<?php
// customers_controller.php

class CustomersController extends AppController {
    var $name = 'Customers';

    function index() {
        // Contain the child method.
        $this->Customer->contain(array(
            'Score' => array(
                'conditions' => array(
                    'Score.test_bk_session_id' => $sessionkey,
                    'Score.lesson' => $lessonid
                )
            )
        ));
        $customers = $this->Customer->find('all', array(
            'conditions' => array(
                'Customer.customers_types' => 'student'
            )
        ));
        // Now you have all your customers, AND their associated
        // scores. No more request action needed (never use that imo)
        $this->set('customers', $customers);

        // Your array should look like this:
        // $customers =
        //array(
        //    [0] => array(
        //        'Customer' => array(<CustomerArray>),
        //        'Score' => array(<ScoreArray>)
        //    ),
        //    [1] => ...
        //)
    }
}

?>

我写得非常快，请原谅任何错误或错误的假设。希望这有助于解决您的问题。
