【问题描述】：
我正在尝试将 php 与 mysql 一起使用。基本上我有一个用户填写表格的索引页面和显示所有行的另一个页面。我为每一行设置了复选框，用于删除选定的行/行。我正在尝试创建一个仅显示所选行的新页面（即详细信息）。 我正在尝试使用 $_GET 但我做不到。也许语法是错误的。欢迎任何帮助。
以下是相关代码部分：
display.php:
<?
require_once('auth.php');?>

<head>
<title>Goruntule</title>
<meta name="GENERATOR" content="Arachnophilia 4.0">

<body bgcolor="#ffffff" text="#000000" link="#0000ff" vlink="#800080" alink="#ff0000">
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" name="checkboxForm">
<?
require "config.php"; // All database details will be included here
$page_name="display.php";
$start=$_GET['start']; // To take care global variable if OFF
if(!($start > 0)) { // This variable is set to zero for the first page
$start = 0;
}
$eu = ($start -0);
$limit = 10; // No of records to be shown per page.
$this1 = $eu + $limit;
$back = $eu - $limit;
$next = $eu + $limit;
// WE have to find out the number of records in our table. We will use this to break the pages
$query2=" SELECT * FROM table1 ";
$result2=mysql_query($query2);
echo mysql_error();
$nume=mysql_num_rows($result2);
/////// The variable nume above will store the total number of records in the table////
/////////// Now let us print the table headers ////////////////

正如我所说，我猜测的唯一问题是语法，或者当我给 var1 一个特定的 id 时我可以回显该行的一些小问题。 如果我要重新发布，我很抱歉，但我找不到答案。谢谢！
编辑：我正在考虑删除复选框部分并在 while 循环中添加 gif 链接，用户可以在其中删除、编辑或详细查看相应行。我猜似乎更容易。
