如何在CI中将多维数组插入数据库？

I have this array.

Array
(
[customer_id] => Array
    (
        [customer_id] => 132
    )

[file_name] => Array
    (
        [0] => ht5appletv11.png
        [1] => twitter-100px11.png
    )

[file_path] => Array
    (
        [0] => C:/xampp/htdocs/maintenance_assurance_sys/uploads/ht5appletv11.png
        [1] => C:/xampp/htdocs/myproject/uploads/twitter-100px11.png
    )

)

I want to insert these data into database with Row by Row in CI.But the customer_id is always same in each row. file_name and file_path will change. For example:

How can i do that?

+---------------------------------------------------------------------+
|  customer_id     | file_name                |file_path              |
|   132            |  ht5appletv11.png        | C:/xampp/htodcs/..... |
|   132            |  twitter-100px11.png     | C:/xampp/htodcs/..... |
+---------------------------------------------------------------------+

Here is my Code... 

function insertUploadedFiles($data)
{   

    foreach ($data as $fileData)
    {   
        $datas[] = array(
            'customer_id' => $fileData['customer_id'],
            'file_name' => $fileData['file_name'],
            'file_path' => $fileData['file_path']
        );

    }
    $this->db->insert_batch('t_customer_file_ref', $datas);
}

But it's only get customer_id and the file_name & file_path show error like this.

Message: Undefined index: file_name

Undefined index: file_path

我有这个数组。 

  Array 
（\  n [customer_id] =＆gt;数组
（
 [customer_id] =＆gt; 132 
）
 
 [file_name] =＆gt;数组
（
 [0] =＆gt; ht5appletv11.png 
  [1] =＆gt; twitter-100px11.png 
）
 
 [file_path] =＆gt;数组
（
 [0] =＆gt; C：/xampp/htdocs/maintenance_assurance_sys/uploads/ht5appletv11.png  
 [1] =＆gt; C：/xampp/htdocs/myproject/uploads/twitter-100px11.png 
）
 
）
   
 
 
 I 想要在CI中逐行插入这些数据到数据库中。但是每行的customer_id总是相同的。  file_name和file_path将更改。  
例如： 
 
 
 
 
我该怎么做？ 
  
 
 
  + ---  --------------------------------------------------  ---------------- + \ N |  customer_id |  file_name | file_path | 
 |  132 |  ht5appletv11.png |  C：/ xampp / htodcs / ..... | 
 |  132 |  twitter-100px11.png |  C：/ xampp / htodcs / ..... | 
 + -----------------------------------  ---------------------------------- + 
   
 
 <  p>这是我的代码...  
 
 
  function insertUploadedFiles（$ data）
 {
 
 foreach（$ data as $ fileData）
 {
 $  datas [] = array（
'customer_id'=＆gt; $ fileData ['customer_id']，
'file_name'=＆gt; $ fileData ['file_name']，
'file_path'=＆gt; $ fileData ['  file_path'] 
）; 
 
} 
 $ this-＆gt; db-＆gt; insert_batch（'t_customer_file_ref'，$ datas）; 
} 
   
 
  
但它只获得customer_id和file_name＆amp;  file_path显示如下错误。 
 
 
 
 
消息：未定义的索引：file_name  
 
 
未定义的索引：file_path

    Please try the below code,

    function insertUploadedFiles($data)
{   

foreach ($data['file_name'] as $key => $fileData)
{   
      $datas[] = array(
          'customer_id' => $data['customer_id']['customer_id'],
          'file_name' => $fileData,
          'file_path' => $data['file_path'][$key]
      );

  }
  $this->db->insert_batch('t_customer_file_ref', $datas);
}

    I assume that both the file_name and file_path elements will have same indexes like 0, 1, 2 etc.,
