Codeigniter/PHP如何正确使用for循环？

我的型号如下

Array ( [cFirstName] => Array ( [0] => Tom [1] => Alexa ) [cLastName] => Array ( [0] => Jones [1] => Planter ) )

//Get all the customers currently pending 
//install for the user making the request. 
function getAllCustomersPendingInstall()
{
    $data=array();

    //Need to use sessions to display proper 
    //records for each user. Temp set id to user #7
    $id = 7;

    //query the db and return all record where SalesRepId == $id
    $query = $this->db->get_where('customers', array('SalesRepId' => $id));

        //check logic, if rows exist RETURN all rows, else
        //return message that no pending installs is available.
        if($query->num_rows != 0) {
            foreach($query->result() as $row) {
                $data['cFirstName'][] = $row->customerFirstName;
                $data['cLastName'] [] = $row->customerLastName;
            }
        } else {
            $data = "No pending installs available!";
            return $data;
        }   
//the following var_dump is only showing the last record.
//need to show all rows (which should be 2)
//var_dump($data); exit;
return $data;           
}

我的控制器如下所示

Array ( [cFirstName] => Array ( [0] => Tom [1] => Alexa ) [cLastName] => Array ( [0] => Jones [1] => Planter ) )

//Get all the customers currently pending 
//install for the user making the request. 
function getAllCustomersPendingInstall()
{
    $data=array();

    //Need to use sessions to display proper 
    //records for each user. Temp set id to user #7
    $id = 7;

    //query the db and return all record where SalesRepId == $id
    $query = $this->db->get_where('customers', array('SalesRepId' => $id));

        //check logic, if rows exist RETURN all rows, else
        //return message that no pending installs is available.
        if($query->num_rows != 0) {
            foreach($query->result() as $row) {
                $data['cFirstName'][] = $row->customerFirstName;
                $data['cLastName'] [] = $row->customerLastName;
            }
        } else {
            $data = "No pending installs available!";
            return $data;
        }   
//the following var_dump is only showing the last record.
//need to show all rows (which should be 2)
//var_dump($data); exit;
return $data;           
}

我的问题是如何在视图中正确地使用FOR循环，以便循环所有返回的行。正如您所看到的，

打印\u r

正确地返回了正确的行-但是我无法循环它们。谢谢你的帮助！非常感谢

我认为您要做的是为数据库返回的每一行获取一个关联数组。如果我错了，请纠正我

应该解决你的问题

{
    $this->load->library('table');
    $this->load->model('GetData');
    $data['optimum'] = $this->GetData->getAllCustomersPendingInstall();
    $this->load->view('welcome_message', $data);
}

然后在您的视图中（其中

$customer

是

$data

数组）

在您的视图中尝试以下操作：

<?php foreach($customer as $c):?>
<?php echo $c['cfirst'];?>
<?php endforeach;?>

这不回显任何内容这不回显任何工作内容，但什么是数据索引？为什么需要允许代码运行？您需要创建一个数组数组。您以前的做法是创建一个带有2个键的关联数组，然后在模型中覆盖foreach循环每次迭代的值。感谢您的帮助，虽然您的答案工作正常，但我选择了上面的答案，因为我觉得它与我的原始代码融合得更好。非常感谢。这是可行的，但什么是数据索引？为什么需要允许代码运行？您需要创建一个数组数组。您以前的做法是创建一个带有2个键的关联数组，然后在模型中覆盖foreach循环每次迭代的值。感谢您的帮助，虽然您的答案工作正常，但我选择了上面的答案，因为我觉得它与我的原始代码融合得更好。非常感谢。
