在我的图书馆管理系统中传递id和button单击参数后，我想以表格格式显示结果
[英]I want to display my results in table format after passing a parameter of id and button click in my library management system
问题描述
这是我的全部代码，用于使用特定学生的学生ID生成报告。 我的SQL查询将显示该学生尚未归还的书籍清单。
在调试时，我注意到如果我在代码中手动放置任何学生ID，我可以看到结果，但是按钮单击功能不起作用...按钮不知何故没有从我的SQL查询中获取任何数据，也没有执行。

需要在输入字段值中输入studentid 。 这样，当表单提交时，它就会发布并生成报告。 更新以下行并检查。
<input class="form-control" type="text" name="studentid" id="studentid" autocomplete="off" required value="<?php echo strtoupper($_POST['studentid']); ?>" />
