Forloop錯誤codeigniter

Question

我寫了一個代碼發送電子郵件到控制器中的多個電子郵件地址，但我想我寫錯了，我不確定我是否在forloop的寫入部分寫了明確的電子郵件。對不起，這可能是一個簡單的問題，但我是這個領域的一些新東西。

public function sendEmailforUnpaidInvoiceFromDB() { 
    //fetch tha data from the database 
    $this->load->model('invoice_page'); 
    $foo = $this->invoice_page->getInvoicesForNotification(); 
    $result = json_decode(json_encode($foo[0]), true); 
    foreach ($foo as $result){ 
    $this->load->library('email'); 
    $this->email->from('helloworld@hello.com', 'HELLO'); 
    $this->email->to($result['Email']); 
    $this->email->subject('Pay Payments'); 
    //$msg = $this->load->view('mypayment_view', '', true); 
    $this->email->message('your due date is '.$result['duedate']); 
    $returnvalue = $this->email->send(); 


    if(!$returnvalue) { 
     alert("email failed to send"); 
    } else { 
    // $uptArray = array('customer_notified_dt' => NOW()); 
     //$this -> db -> update('invoice', $uptArray); 
     } 
    $this->email->clear(TRUE); 
    } 
} 

我從模型中獲得2個數組，包括Email和duedate。 錯誤圖片和

Answer 1

問題是在這裏，

$result = json_decode(json_encode($foo[0]), true); 
foreach ($foo as $result){ 
       ^// overwriting previous variable 

如果$result爲對象，請訪問使用->

$result->email; 

如果其陣陣Ÿ

$result['email']; 

編輯

你得到只有一個原因，

$result = json_decode(json_encode($foo[0]), true); 
            ^

你只考慮第一個索引列，刪除0爲指標。

Answer 2

您正試圖將對象讀取爲數組，如錯誤所述。嘗試更換這些：

​​

有了這些：

$this->email->to($result->Email); 
$this->email->message('your due date is '.$result->duedate);

試試這個：

public function sendEmailforUnpaidInvoiceFromDB() { 
     //fetch tha data from the database 
     $this->load->model('invoice_page'); 
     $foo = $this->invoice_page->getInvoicesForNotification(); 

     foreach ($foo as $result){ 
     $this->load->library('email'); 
     $this->email->from('helloworld@hello.com', 'HELLO'); 
     $this->email->to($result->Email); 
     $this->email->subject('Pay Payments'); 
     //$msg = $this->load->view('mypayment_view', '', true); 
     $this->email->message('your due date is '.$result->duedate); 
     $returnvalue = $this->email->send(); 


     if(!$returnvalue) { 
      alert("email failed to send"); 
     } else { 
     // $uptArray = array('customer_notified_dt' => NOW()); 
      //$this -> db -> update('invoice', $uptArray); 
      } 
     $this->email->clear(TRUE); 
     } 
    }
