可能重复：
如何在 php 中显示两个具有相同数据的不同表的信息，但名称或 id 不同

此代码显示表的两个信息只想显示我选择的一个表信息

因为有两个表菜单和非菜单。

并且在这 2 个表中，n 个字段和项目作为输入给出，所以当我选择表中的一个项目时，将显示这些项目的信息

因为当我选择表格的特定项目时，它会同时显示表格信息。

任何尝试n帮助..

<?php
session_start();
if(isset($_GET['id']))
{
    $_SESSION['n']=$_GET['id'];
}

$n=$_SESSION['n'];

$con=mysql_connect("localhost","root","");

使主题独占。如果我理解正确，这可能会起作用：

if(isset($_GET['id']) && (!isset($_GET['nid']))) {
// id tasks
die;
}

if(isset($_GET['nid']) && (!isset($_GET['id'])) ) { 
// nid tasks
die;
}

更新：

<?php
session_start();
if ( isset( $_GET[ 'id' ] ) && ( !isset( $_GET[ 'nid' ] ) ) ) {
  $_SESSION[ 'n' ] = $_GET[ 'id' ];
  $n = $_SESSION[ 'n' ];
  $con = mysql_connect( "localhost", "root", "" );
  mysql_select_db( "menu", $con );
  $sql    = "select * from menus where id=$n";
  $result = mysql_query( $sql );
  $row    = mysql_fetch_array( $result );
  echo "<table border=0 width=100%  ><tr>";
  echo "<td><h1><img src=\"images/veg.jpg\" height=35 width=35  /> $row[tittle]</h1></td>";
 ?>

<?php echo" <td><h1><img src=\"images/telephone1.jpg\" height=35 width=35  /> $row[phone]    </h1></td>";
  //<img src="images/Kapu-Lighthouse.jpg"  title="Non veg" width="210" height="150" />
  //echo " - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -<br>";
