问题描述

我可以在数据库中插入多行,但问题是当我试图更新它给我一个Codeigniter错误消息。这是我的模型,实际上我没有什么重要的控制器中发现错误,是因为我只是加载控制器中的模型。

  $ data = array(); 
// $ todayDate = date('Y-m-d');
for($ i = 1; $ i // $ code = $ _ POST ['code'] [$ i] ;
if($ _ POST ['code'] [$ i]!=''){
$ data [] = array(
$ code ='code'=> $ _POST [ 'code'] [$ i],
'price'=> $ _POST ['sell']
);
}
}
$ linksCount = count($ data);

if($ linksCount){
$ this-> db-> where('code',$ code);
$ this-> db-> insert_batch('sell_rate',$ data);
}

return $ linksCount;

解决方案

code>以下部分应为

  $ data [] = array(
$ code ='code' => $ _POST ['code'] [$ i],
'price'=> $ _POST ['sell']
);

替换为

  $ data [] = array(
'code'=> $ _POST ['code'] [$ i],
'price'=> $ _POST ['sell' ]
);

并更新您应该使用的值 update_batch 而不是 insert_batch

  $ this-& update_batch('yourtableName',$ data,'code'); //'code'is where key 

替换 yourtableName 与您的原始表名和代码正在用于其中键,因此您不需要使用 $ this-> db->其中('code',$ code)



参考 CodeIgniter


I can insert multiple rows in the database, but the problem is when I am trying to update it gives me a Codeigniter error message. Here is my model, actually I have nothing significant in the controller to find an error in, is because I just load that model in controller.

$data  = array();
//$todayDate = date('Y-m-d');
for($i = 1; $i < count($_POST['code']); $i++) {
    //$code=$_POST['code'][$i];
    if($_POST['code'][$i] != '') {
        $data[] = array(
            $code='code' => $_POST['code'][$i],
            'price' => $_POST['sell']
            );
    }
}
$linksCount = count($data);

if($linksCount) {
    $this->db->where('code',$code);
    $this->db->insert_batch('sell_rate', $data);
}

return $linksCount;

解决方案

In your Model following part should be

$data[] = array(
    $code='code' => $_POST['code'][$i],
    'price' => $_POST['sell']
);

replaced with

$data[] = array(
    'code' => $_POST['code'][$i],
    'price' => $_POST['sell']
);

and to update the values you should use update_batch instead of insert_batch

$this->db->update_batch('yourtableName', $data, 'code'); // 'code' is where key

Replace yourtableName with your original table name and code is being used for where key, so you don't need to use $this->db->where('code',$code).
