Question

我已经开始为关于生物的游戏撰写 PHP 脚本, 有 4 是/ no 个问题, 我试图做的是写一个函数, 它将显示两个按钮, 显示是和否, 然后每次运行函数时给出不同的名称, 比如是是 1 和 No 1, 然后下次运行函数时, 按钮的名称将是是是 2 和 no 2 。

我已尝试这样做,但工作不正确,下面是我至今所遵循的守则,任何帮助都将非常感激。

session_set_cookie_params(2592000);
session_start();

<h1>Creature Guessing Game</h1>
<p> Welcome to the creature guessing game! </p>
<p>Click the button below to start or restart the game </p>

<form method="post" action="Creatures.php">

 <?php
 $questions = array( Does the creature live on land? ,  Does it have wings? ,  Does it live near water? ,  Can it fly? );
 function repeat()
 {
 $number = 0;
 $number++;
 echo "<form method = post  action= Creatures.php >
<input type= submit  name= yes .$number value= Yes  />
<input type= submit  name= no .$number value= No  />
</form>";

 }
//If form not submitted, display form.
if (!isset($_POST[ start ])){
?>
<?php
} //If form is submitted, process input
else{ 
switch($_POST)
{
case yes1:
echo $questions[0];
repeat();
break;
case no1:
echo $questions[1];
repeat();
break;
case yes2:
echo $questions[2];
repeat();
break;
case no2:
$questions[3];
repeat();
}
}

Answer 1

要做到这一点,您需要保持请求之间的状态。

 function repeat() {
      $number = $_SESSION[ number ];
      $number++;
      echo "<form method = post  action= Creatures.php >
     <input type= submit  name= answer  value= Yes  />
     <input type= submit  name= answer  value= No  />
     </form>";
     $_SESSION[ number ] = $number;
 }

开关

   if($_POST[ answer ]== Yes ) {
      开关($_SESSION[ number ]) {
            case 1:
            break;
            case 2:
            break;
      }
   } else {
      开关($_SESSION[ number ]) {
            case 1:
            break;
            case 2:
            break;
      }
   }

Answer 2

I am not in agreement with the accepted answer: Here is an easier way to go about it without session:

function repeat() {
      static $number = 0;
      $number++;
      echo "<form method = post  action= Creatures.php >
     <input type= submit  name= answer  value= Yes  />
     <input type= submit  name= answer  value= No  />
     </form>";
 }

Answer 3

您必须将数字保存在会话或 cookie 中, 因为它会松开提交( 重新加载) 的每页时间的值。
