HTML $ _GET方法不起作用

标签： php html forms get

我正在尝试从我的某个页面中的列表中获取值。问题是它不显示它应该显示的值。举个例子，我有这些;

i）$ _GET ['name'] = a value
ii）$ handsome = $ _GET ['name']
iii）$ qq = mysql_query（“SELECT * FROM student where name ='$ handsome';”）

当我测试值检查时，$ _GET和$ handsome产生相同的结果（有效），但$ qq ['name']或从数据库中获取的任何其他值都不显示任何值。页面没有指定任何错误，它只是空的。

对不起，如果代码太长而且令人困惑。

    $sqp = mysql_query("SELECT * FROM student WHERE name='$name'");

{
    if($_SESSION['level'] == 'student')
    {
        $us = $_SESSION['matric'];
    }
    if($_SESSION['level'] == 'admin')
    {
        $us = $_SESSION['user'];
    }

    $sql = mysql_query("SELECT * FROM student WHERE matric = '$us';");
    $sqq = mysql_query("SELECT * FROM place");
    $sqe = mysql_query("SELECT * FROM student");
    $sqc = mysql_query("SELECT * FROM student");
    $sol = mysql_fetch_array($sql, MYSQL_ASSOC);

我想知道出了什么问题。在此之前（在较小的缩放页面上），$ _GET始终有效。请帮帮我。提前谢谢大家。
