Question

我有一个页面，为每个游戏生成一个游戏列表和按钮，价值为＃34;购买游戏＆＃34;。目标是在单击特定游戏的按钮时执行多个SQL查询。

访问＆＃39;，＆＃39; consolename＆＃39;等的合适方式是什么？对于来自ARRAY的每个游戏，并在另一个页面上执行查询 - purchase.php？

注意：我确实考虑过使用会话但是当我将变量$ index作为SESSION变量传递时，我只会一直得到最终值。

buygame.php

<?php
session_start();
//connect to db
dbConnect("root", "") ;
dbSelect("webdesign");

//SEARCH FOR GAMES
print "<h3>Games to Buy: </h3>";
$query = "SELECT  gamecode,name, consolename,price, points, genre from game";
$result = runQuery($query);
while($row = mysql_fetch_array($result))
{ 
  $array[] = $row;
}
$index =0 ;

//DISPLAYING A LIST OF GAMES
 while($index<sizeof($array))
  { 
echo $array[$index]['name'];
echo $array[$index]['consolename'];
echo $array[$index]['genre'];
echo ("Price is: ".$array[$index]['price']." USD"); 
echo ("Loyalty Points: ".$array[$index]['points']);

//THE BUTTON "BUY GAME"
echo("<a href='purchase.php'><input type='submit' name='submit[$index]' value='Buy Game'/></a>");
$index = $index + 1;
}
?>

purchase.php

<?php
session_start();
//connect to database
dbConnect("root", "") ;
dbSelect("webdesign");
$index = 0;
echo "Button clicked ";

//I am trying this but I'm sure that this is not right
if (isset($_POST['submit[$index'])){
  print "$index was clicked";
}
?>

Answer 1

//THE BUTTON "BUY GAME"
$gamecode = $array[$index]['gamecode'];
echo("<a href='purchase.php?gamecode=$gamecode'><input type='submit' name='submit[$index]' value='Buy Game'/></a>");
$index = $index + 1;

然后在purchase.php你完全知道，已经买了什么游戏。

Answer 2

在buygame.php中将代码更改为：

//THE BUTTON "BUY GAME"
echo("<a href='purchase.php?gamecode={$array[$index]['gamecode']}'><input type='submit' name='submit[$index]' value='Buy Game'/></a>");

在purchase.php

<?php

if(isset($_GET['gamecode'])) {
  echo $_GET['gamecode'];
//and make ......
}

如何在链接中发送一些信息（值）（<a>) to another page?</a>
