如何可以利用这 - >数据[]从控制器，以查看在PHP CI

Question

for ($i = 0; $i < $count; $i++) { 
    $this->data["schedule_count"] = $count; 
    $this->data["user_travels" . $i] = $this->travel_order_model->get_travel_schedule($this->data["user_dates"]{$i}->id); 
} 

错误我通过内部循环变量遇到了

严重性：警告

Message: Invalid argument supplied for foreach()

Filename: travel_order/travel_order_report_summary.php

Line Number: 213

Answer 1

for ($i = 0; $i < $count; $i++) { 
    $this->data["schedule_count"] = $count; 
    $this->data["user_travels"][$i] = $this->travel_order_model->get_travel_schedule($this->data["user_dates"][$i]->id); 
} 
$this->load->view('your_view_file', $data); 

您查看文件，您可以打印数据这种方式，

foreach($user_travels as $travelData){ 
    print_r($travelData); 
} 

Answer 2

for ($i = 0; $i < $count; $i++) { 
    $this->data["schedule_count"] = $count; 
    // pass Id 
    $this->data["user_travels"][$i] = $this->travel_order_model->get_travel_schedule($this->data["user_dates"][$i]->getId()); 
}
