php未定义的索引变量跟随程序,php,Php,您好，我正在尝试下面的程序 <?php //define class database connectivity class dbconnect { var $conn; function dbcon() { if(!isset($conn)) //database connectivity { $conn = mysqli_connect('localhost','root','username','p

请帮助我如何检索

首先，您的状态字段名为“name”，但您正在查找“pro_state”的POST值。因此，改变：

 $select = "<select name='name'>";

$select=”“；

…到

 $select = "<select name='pro_state'>";

$select=”“；

此外，您正在尝试访问POST值“flw_staff”，但表单中没有任何具有该名称的字段。

帮助您检索什么？

 $select = "<select name='pro_state'>";
