Follow Teacher Zhu’s video "ThinkPHP5 Rapid Development of Enterprise Sites" to write code. When running the admin_edit page, an "undefined array index: is_update" error appears. I don’t know how to solve it. I would like to ask you for help. Thank you!
Admin.php controller code:
//Perform update operation
public function update(Request $request)
{
if ($request->isAjax(true)) {
//Get the submitted data and automatically filter out null values
$data = array_filter($request->param() );
//Set update conditions
$where = ['is_update' => $data['is_update']];
//Update user table
$result = AdminModel::update($data, $where);
//Prompt message for successful update
$status = 1;
$message = 'Update successful';
//If the update fails
if (is_null($result)) {
$status = 0;
$message = 'Update failed';
}
}
return ['status' => $status, 'message' => $message];
}
admin_edit .html code (the html page has been tested and can run normally after deleting the controller logic code):
{layout name="public/layout" /}
<div class="x-body">
<form class="layui-form">
<div class="layui-form-item ">

I found the cause of the error. The code for saving the Session when logging in is as follows: //Session::set('user_id', $userName);Session::set('user_info', $data);The above $data is only The username and password information of admin does not include field information such as is_update. I changed it to this: //Session::set('user_id', $userName);Session::set('user_info', $admin); Bug disappears. Note: Change the Base controller as well: define('USER_ID', Session::get('user_info.id'));
