Question

我正在尝试创建一个多字段搜索选项。表单中有四个字段，用户可以将信息输入任何一个或多个字段，它将查询数据库。

SQL在myPHP管理员中运行，但我从mySQL中收到了一堆丑陋的错误。

当前错误

准备失败：（1054）'字段列表'中的未知列'Employee.Fname' 致命错误：在非对象中调用成员函数bind_param（）第41行/nfs/stak/students/g/greenjas/public_html/employee_info.php

以下是表单代码：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>

<head>
    <title>Bicycle Store Employees</title>
    <link rel="stylesheet" type="text/css" href="web.css" />
</head>
<body>
    <h1>Bicycle Store Manager</h1>
    <h2>Customized Business Management for Bicycle Stores</h2>

    <h3>FORM: RETRIEVE EMPLOYEE INFORMATION</h3>

    <form action="employee_info.php" method="post">
    <h3>Employee Information</h3>
    <h4>First Name: <input type="text" name="Fname"/>
    Last Name: <input type="text" name="Lname"/></h4>

    <h3>Store Information</h3>
    <h4>
    Department #: <input type="text" name="Dno"/>
    Store #: <input type="text" name="Store_num"/>

    <input type="submit" name="submit" value="SEARCH"/>
    </h4>
    </form>

    <p><a href="index.html">HOME</a></p>

</body>
</html>

这是php

Mysql表名在linux中区分大小写。请参阅此文档：http://dev.mysql.com/doc/refman/5.1/en/identifier-case-sensitivity.html

因此，如果实际表格是“EMPLOYEE”，那么您不能将其称为“员工”。

mySQLi准备失败，多个？从形式
