在crud中遇到php错误

我正在尝试安装

groceryCRUD

。我已经成功安装了代码点火器，但当我尝试访问

/index.php/examples

时，会显示许多错误，例如：

<h4>A PHP Error was encountered</h4>

<p>Severity: Notice</p>
<p>Message:  Undefined property: stdClass::$</p>
<p>Filename: libraries/Grocery_CRUD.php</p>
<p>Line Number: 1612</p>

有人能帮我修理虫子吗？谢谢。

这些错误似乎是您试图错误地访问数据（数组与对象），或者数据设置不正确。注释掉导致错误的四行，然后尝试记录或打印各个变量，直到您可以确定是哪一行导致了错误。我将首先测试这三个：

$data->list[$num_row]

$data->primary_key

$row->{$data->primary_key}这个输出打印（$data->list[$num_row]）：stdClass对象（[id]=>1[department]=>Purchasing[tgl_daftar]=>01/06/2020[jabatan_id]=>2[aktif]=>Y[$num\u row]->primary\u key\u value）。此输出：遇到PHP错误严重性：注意消息：未定义属性：stdClass:：$primary\u key\u value

文件名：libraries/groundry\u CRUD.PHP

行号：1612

请不要将澄清添加为注释。请将其编辑到您的问题中。

foreach($data->list as $num_row => $row)
{
    $data->list[$num_row]->primary_key_value = $row->{$data->primary_key};
    $data->list[$num_row]->edit_url = $data->edit_url.'/'.$row->{$data->primary_key};
    $data->list[$num_row]->delete_url = $data->delete_url.'/'.$row->{$data->primary_key};
    $data->list[$num_row]->read_url = $data->read_url.'/'.$row->{$data->primary_key};
}
