Question

这是我用来更新所有行的代码，我使用的是update_batch函数，但是它无法正常工作

     SELECT LogDate,
     LogTime  AS InTime,
     (
         SELECT TOP 1 t1.LogTime
         FROM   yourTable AS t1
         WHERE  Mode = 0
     )        AS OutTime   FROM   yourTable  WHERE  Mode = 1

我的$ users var_dump看起来像这样

 public function edit_project_involved($users)
{

    foreach ($users as $v_user) {

    $data=array('involved'=>1);
    $v=$this->db->where('user_id',$v_user);
    $query=$this->db->update_batch('tbl_users',$data,$v);
    }

    if($query)
    {
        return true;
    }

}

我收到这样的错误

C:\wamp64\www\spectra\application\models\Project_model.php:536:
array (size=3)
0 => string '40' (length=2)
1 => string '42' (length=2)
2 => string '37' (length=2)

文件名：C：/wamp64/www/spectra/system/database/DB_query_builder.php

行号：2010

我的表格看起来像这样

One or more rows submitted for batch updating is missing the specified index.

var_dump（$ data）看起来像这样

user_id     username        involved
    1         admin           0
    36        siraj           0
    37        faizal          0
    38        nesru           0
    40        jaseer          0
    42        maltu           0
    43        shahul          0     
    44        samsheera       0

您没有遵循文档https://www.codeigniter.com/user_guide/database/query_builder.html

中提到的规则

试试这个（注意循环外的update_batch以及数组的制作方式）

foreach ($users as $v_user) {
  $data[] = array(
   'user_id' => $v_user,
   'involved'=> 1
  );
}
$query = $this->db->update_batch('tbl_users',$data,'user_id');

codeigniter中的update_batch
