请帮助，我正在尝试创建php分页。我第一次运行它时显示了我指定的行的确切10条记录，但是一旦我点击下一条以获得另外10条它就会返回：
注意：未定义的索引：第7行的C：\ wamp \ www \ seore \ 1.em \ r \ recordsbycourse.php中的课程 注意：未定义的索引：第8行的C：\ wamp \ www \ seore \ 1.em \ r \ recordsbycourse.php中的课程 注意：未定义的索引：第9行的C：\ wamp \ www \ seore \ 1.em \ r \ recordsbycourse.php中的课程
以下是代码：
<?php
include_once("mysession.php");
include_once("connect.php");
?>
<?php
$course_code = $_POST['course'];
$semester = $_POST['semester'];
$level = $_POST['level'];
$result1 = mysqli_query($con, "SELECT *
FROM srcoe_nce_courses_registration
WHERE course_code = '$course_code'
AND semester = '$semester'")
or die(mysqli_error($con));
$row1=mysqli_fetch_array($result1);
$regno= $row1['regno'];
?>

您应该使用POST方法而不是Service方法。
