Undefined array index: is_update

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 ">

<label for="username" class="layui-form-label">

<span class="x-red">*</ span>Login name

</label>

<div class="layui-input-inline">

<input type="text" id ="username" name="username" required="" lay-verify="required" autocomplete="off" value="{$admin.username}"

class="layui-input" disabled>

</div>

<div class="layui-form-mid layui-word-aux">

<span class="x- red">*</span>Username cannot be modified

</div>

</div>

<div class="layui- form-item">

<label for="L_email" class="layui-form-label">

<div class="layui-input-inline">

</div>

<div class="layui-form-mid layui-word-aux">

</div>

</div>

<div class="layui-form-item">

<label for="L_pass" class="layui-form-label">

<span class="x-red">*</span>新密码

</label>

<div class="layui-input-inline">

<input type="password" id="password" name="password" required="" lay-verify="password" autocomplete="off" class="layui-input"

value="123456" placeholder="密码">

</div>

<div class="layui-form-mid layui-word-aux">

6到12个字符

</div>

</div>

<!--添加隐藏字段-->

<input type="hidden" name="id" value="{$Think.session.user_info.id}" lay-filter="id">

<input type="hidden" name="is_update" value="{$Think.session.user_info.is_update}" lay-filter="is_update">


<div class="layui-form-item">

<label for="repassword" class="layui-form-label">

</label>

<button class="layui-btn" lay-submit lay-filter="save" id="btnSubmit">

保存

</button>

</div>

</form>

</div>

<script>

layui.use('form', function () {

// $ = layui.jquery;

var form = layui.form;

// ,layer = layui.layer;


//自定义验证规则

form.verify({

password: [/(. ){6,12}$/, '密码必须6到12位']

});


//监听提交

form.on('submit(save)', function () {

$.ajax({

type: 'POST',

url: "{:url('admin/update')}",

data: $(".layui-form").serialize(),

dataType: "json",

success: function (data) {

if (data.status == 1) {

layer.msg(JSON.stringify(data.message), {icon:6,time:2000}, function() {

// 获得frame索引

var index = parent.layer.getFrameIndex(window.name);

//关闭当前frame

parent.layer.close(index);

});

} else {

layer.msg(JSON.stringify(data.message), {icon:5,time:2000});

}

}

});

return false;

});

});

</script>

    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'));

    Fortunately, you found out the reason, otherwise I would have spent a long time reading this code.
