從控制器傳遞foreach的值來查看

Question

我想從控制器傳遞foreach值來查看，但我只收到一個空數組。在下面的代碼基於foreach中的值我執行了一個查詢，我想設置值，以便我可以在視圖中使用它。

foreach($logresponse as $row1){ 
    $customerid = $row1['customerid']; 
    $topicid = $row1['topicid']; 
    $todolistid = $row1['todolistid']; 
    $sqlQry="select leadid,customerid as leadcustid,formname from lead_frontend where customerid='$customerid' order by leadid DESC limit 1"; 
    $leadInfo[] = $this->execute_flatten($sqlQry); 
    if($topicid == 1){ 
     $query2="SELECT a.*,b.username,b.user_id,b.group_id,b.email as salesmanemail,d.email,d.phone1,e.subject,e.subject1,e.content,e.embed_template FROM todolist_frontend as a LEFT JOIN users_backend as b ON a.salesmanid=b.user_id LEFT JOIN customer as c ON c.customerid=a.customerid LEFT JOIN customer_address as d ON d.customerid=a.customerid LEFT JOIN admin_email_action as e ON a.combination_id=e.combination_id where a.todolistid='$todolistid'"; 
    } 
    else if($topicid == 2){ 
     $query2="SELECT a.*,b.username,b.user_id,b.group_id,b.email as salesmanemail,d.email,d.phone1,e.subject,e.subject1,e.call_info as content FROM todolist_frontend as a INNER JOIN users_backend as b ON a.salesmanid=b.user_id INNER JOIN customer as c ON c.customerid=a.customerid INNER JOIN customer_address as d ON d.customerid=a.customerid INNER JOIN admin_call_action as e ON a.combination_id=e.combination_id where a.todolistid='$todolistid'"; 
    } 
    else if($topicid == 18){ 
     $query2="SELECT a.*,b.username,b.user_id,b.group_id,b.email as salesmanemail,d.email,d.phone1,e.subject,e.subject1,e.call_info as content FROM todolist_frontend as a INNER JOIN users_backend as b ON a.salesmanid=b.user_id INNER JOIN customer as c ON c.customerid=a.customerid INNER JOIN customer_address as d ON d.customerid=a.customerid INNER JOIN admin_managercall_action as e ON a.combination_id=e.combination_id where a.todolistid='$todolistid'"; 
    } 
    else{ 
     $query2="SELECT a.*,b.username,b.user_id,b.group_id,b.email as salesmanemail,d.email,d.phone1,e.content,e.subject1,f.emailname as subject,g.mailername AS mailersubject FROM todolist_frontend as a LEFT JOIN users_backend as b ON a.salesmanid=b.user_id LEFT JOIN customer as c ON c.customerid=a.customerid LEFT JOIN customer_address as d ON d.customerid=a.customerid LEFT JOIN admin_mailer_action as e ON a.combination_id=e.combination_id LEFT JOIN emailtype_backend as f ON e.subject=f.emailid LEFT JOIN mailer_backend AS g ON e.subject = g.mailerid where a.todolistid='$todolistid'"; 
    } 
    $result = $this->execute_flatten($query2); 

    $subjecttodo = array(); 
    foreach ($result as $res1){ 
     if($res1['topicid'] == 1 && !empty($res1['subject'])){ 
      $subject1 = $res1['subject']; 
      $sub_qry="select emailname from emailtype_backend where emailid=$subject1"; 
      $subject_result=$this->execute_flatten($sub_qry); 
      $subjecttodo=isset($subject_result['0']['emailname']) ? $subject_result['0']['emailname'] : ""; 
     } 
     if($res1['topicid'] == 2 || $res1['topicid'] == 18){ 
      $subjecttodo=$res1['subject']; 
     } 
     if($res1['topicid'] == 8){ 
      $subjecttodo=$res1['mailersubject']; 
     } 
    $this->set('subjecttodo', $subjecttodo); 
    } 
    $this->set('leadInfo', $leadInfo); 
}

      $logresponse[$key]['subjecttodo'] = isset($subjecttodo) ? $subjecttodo : ''; 

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

Answer 2

首先檢查你是否得到值代入變量$subjecttodo和$leadInfo foreach循環中。然後將這些值分配給Array。

$subjecttodoArray[] = $subjecttodo; 
$leadInfoArray[] = $leadInfo;  

後，在控制器的功能，試圖通過這個陣列設置像你這樣

$this->set('subjecttodo', $subjecttodoArray); 
$this->set('leadInfo', $leadInfoArray); 

然後嘗試打印內部視圖陣列值這樣

echo "<pre>"; 
print_r($subjecttodo); 
echo "</pre>"; 

echo "<pre>"; 
print_r($subjecttodo); 
echo "</pre>"; 

希望這有助於。
