我需要我的系统仅显示用户点击的一组“分钟”，而不是当前用户参与的每组分钟。
当我单击“图像”查看一组分钟时，它会打印出用户参与的每组分钟，我需要它仅打印出来并能够编辑一组特定的分钟...编辑功能可以工作，但我只需要它打印出用户点击的内容，而不是每组。请任何人都可以帮忙解决这个问题，我花了一整天，不明白如何让它工作。
下面是在 分钟.php 页面中显示 php 和查询的代码，当您单击“查看”图像时，它会将您带到“viewstudentmonths.php”页面，我只希望它打印出分钟您点击的不是每组。

数据库中的分钟表包含以下字段...
1 ID Primary int(10) AUTO_INCREMENT
2 B_number varchar(15) latin1_swedish_ci
3 Date date
4 Time time
5 Discussion text latin1_swedish_ci
6 Actions text latin1_swedish_ci
7 Dateofnextmeeting date
8 Status enum('Submitted', 'Approved', 'Rejected', '') latin1_swedish_ci
9 Supervisor_comments text latin1_swedish_ci
10 E_number varchar(15) latin1_swedish_ci
请帮忙:(
最佳答案
有一些变量我不确定它们是什么 - 更新您的问题以包括 $currentUser这会有帮助。
也就是说，问题可能出在您的 SQL 语句中:
$db->prepare("select * from minute where '$currentUser'=B_number ");
您正在选择位置 $currentUser等于B_number 。但在您的数据库模式中，您显示 B_number是一列。
我会尝试这个 SQL 语句:
$db->prepare("SELECT * FROM `Minute` WHERE `B_number` = '" . $currentUser . "' AND `id` = " . $yourIDVariable );
编辑
您的viewstudentminutes.php将迭代 SQL 查询中返回的每条记录。您需要唯一标识您的Minute记录以仅在您的 viewstudentminutes.php 上显示一个页。您可以通过单击 <img> 访问此页面标签。但你永远不会发送 Minute 的数据您想要的对象通过此表格。您可以通过以下方式添加:
<form class='display:inline' method='post' action='viewstudentminutes.php' onsubmit='viewstudentminutes.php'>
<input type='image' src='view.png' style='padding-top:7px'>
<input type='hidden' name='minute_id' value='" . $ID . "'>
</form>
然后在您的 viewstudentminutes.php 上访问此内容如
$db->prepare("SELECT * FROM `Minute` WHERE `B_number` = '" . $currentUser . "' AND `id` = " . $_POST['minute_id']);
