在这里,我必须#second_area在点击输入时隐藏div id .ID名称是 #employee_id

<form id="search_form" name="search_form" method="get" action="" >

        <table width="98%" id="performance_tbl" align="center">

          <div id="first_row">  
          <tr class="first_tr">
            <th scope="row"><label for="employee_id">Employee ID: </label></th>
            <td><input type="text" name="employee_id" id="employee_id" /></td>
          </tr>
          </div>

          <tr>
            <td>&nbsp;</td>
          </tr>

          <div id="second_area">
           <tr>
            <th scope="row"><label for="company_id">Company Name:</label></th>
            <td><input type="text" name="company_id" id="company_id" /></td>
            <th><label for="department_id">Department Name: </label></th>
            <td><input type="text" name="department_id" id="department_id" /></td>
          </tr>

          <tr>
            <th scope="row"><label for="current_year">Select Year: </label></th>
            <td><input type="number" name="current_year" id="current_year" /></td>
            <th><label for="compare_year">Compare Year: </label></th>
            <td><input type="number" name="compare_year" id="compare_year" /></td>
          </tr>

          <tr>
            <th …

//this is my connection function. It is connecting databse successfully when I check.
$conn = connection($config['servername'],$config['username'],$config['password']);

在此之后,我使用以下代码从数据库中获取数据

$id = 2;
if($conn) {

    try {

        $stmt = $conn->prepare('SELECT * FROM customer_tbl WHERE cus_id = :id');
        $stmt->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

        $stmt->bindParam(':id', $id);

        $results = $stmt->execute();

    }catch (PDOException $e){

        echo 'Error: ' . $e->getMessage();
    }

}

此代码在浏览器上显示以下错误消息

错误:SQLSTATE [IM001]:驱动程序不支持此功能:此驱动程序不支持设置属性

我的代码出了什么问题？为什么我无法从数据库中获取数据？

如果我想使用prepare语句从databese获取此指定数据如何编码？
