$select_db = mysqli_select_db($connection, 'db');

if (!$select_db){
    echo 'Not connected to database';
}
$SelectClass = $_POST ['selectclass'];


$sql= "SELECT * FROM students WHERE class = '$SelectClass'";

$query = mysqli_query($connection, $sql);

if (!$query) {
    die ('SQL Error: ' . mysqli_error($connection));
}
mysqli_close($connection);
?>

看看下面的更新代码：

<body>


<?php

$connection = mysqli_connect ('localhost', 'user', 'password', 'db');

if (!$connection){
    echo 'Not connected to server';
}

$select_db = mysqli_select_db($connection, 'db');

if (!$select_db){
    echo 'Not connected to database';
}
$SelectClass = $_POST ['selectclass'];


$sql= "SELECT * FROM students WHERE class = '$SelectClass'";

$query = mysqli_query($connection, $sql);

if (!$query) {
    die ('SQL Error: ' . mysqli_error($connection));
}
mysqli_close($connection);

//***********Form Submit Goes Here***********//
if($_POST)
{
    $student_id     =   $_POST['student_id'];
    $student_name   =   $_POST['student_name'];
    $student_marks  =   $_POST['obtmarks'];

    //your code for insertion....

}
?>
