Question

我已经看过对Ajax的引用，但我并不完全确定如何将其与数组集成，并且仍然具有正常运行的系统。我想在每次用户按下按钮时更改$ place和$ title的值，我知道我需要一个if语句和一些处理表单的方法（PHP中没有点击），但我不知道除此之外别无他法。我已经粘贴了我的PHP和下面的HTML按钮：

<!DOCTYPE html>
<html>
<head>
<title>StatsCalc V1</title>
<link rel="stylesheet" type="text/css" href="sheen.css">
<link rel="script" type="text/javascript" href="slide.js">
<link rel="icon" type="image/png" href="favicon.ico">
<link href='http://fonts.googleapis.com/css?family=Raleway:500' rel='stylesheet' type='text/css'>
</head>
<body>
      <?php
        $place = 0;
        $title = 0;

        echo '<div class="boxes"><h1>Statistics Calculator: Version 1</h1></div>';

        $links = array('<div class="fancyBoxes"><a href="standardisedForm.php"><img class="mainPic" src="normalDist.svg" alt="a normal distribution, courtesy openclipart.org"></a></div>', "", "");
        echo $links[$place];

        /*if($_GET){
            if(isset($_GET['clickies'])){
                $place = 1;
                $title = 1;
            }
        }*/

        if($_POST['clickies'] and $_SERVER['REQUEST_METHOD'] == "POST"){
            $place = 1;
            $title = 1;
        }

        $subtitle = array('<div class="boxes"><h1>Standardised Score</h1></div>', '<div class="boxes"><h1>Standard Deviation</h1></div>', '<div class="boxes"><h1>Averages</h1></div>');
        echo $subtitle[$title];

      ?>
      <input type="submit" id="clickies" name="clickies" value="" />
      <script src="move.js"></script>
      <script src="slide.js"></script>
      <script src="jquery-1.11.2.js"></script>
      <!--The calculator must be able to field standardised score, standard deviation, and averages (mean/median/mode)-->
      <!--Headings will be assigned with an array; slides will be navigated with tabs on either side of the window-->
      <!--Credit to https://openclipart.org/detail/171055/normal-distn-shaded-outside-1s-by-oderwald-171055 for the Standardised Score image/label thingy-->
</body>

也许这可以让你了解如何做到这一点。

if($_SERVER['REQUEST_METHOD'] == "POST") {

      if (isset($_POST['clickies'])) {
         $count = intval($_POST['count']);
         $count++;
         $place = $count;
         $title = $count;
      }

   } else {
      $place = 0;
      $title = 0;
   }

        echo '<div class="boxes"><h1>Statistics Calculator: Version 1</h1></div>';

        $links = array('<div class="fancyBoxes"><a href="standardisedForm.php"><img class="mainPic" src="normalDist.svg" alt="a normal distribution, courtesy openclipart.org"></a></div>', "", "");

        echo $links[$place];

        echo $place; echo "<br/>";

        $subtitle = array('<div class="boxes"><h1>Standardised Score</h1></div>', '<div class="boxes"><h1>Standard Deviation</h1></div>', '<div class="boxes"><h1>Averages</h1></div>');

        echo $subtitle[$title];

?>
   <form action="" method="POST">
      <input type="submit" id="clickies" name="clickies" value="" />
      <input type="hidden" id="count" name="count" value="<?php echo $place;?>" />   
   </form>

我所做的是需要将按钮放在表单中并放置方法=帖子并将其提交到同一页面

我还将计数存储在隐藏的输入中，并在提交表单时将其传递，并在表单上更新其值，

尝试根据您的需要进行修改

<?php
    $_SESSION["place"] = 0;
    $place = 0;
    $title = 0;
    session_start();
    echo '<div class="boxes"><h1>Statistics Calculator: Version 1</h1></div>';

    $links = array('<div class="fancyBoxes"><a href="standardisedForm.php"><img     class="mainPic" src="normalDist.svg" alt="a normal distribution, courtesy openclipart.org">    </a></div>', "", "");

    if($_POST['clickies'] and $_SERVER['REQUEST_METHOD'] == "POST"){
        $_SESSION["place"] =  $_SESSION["place"] + 1;
        $title = 1;
    }
    echo $links[$_SESSION["place"]];
    $subtitle = array('<div class="boxes"><h1>Standardised Score</h1></div>', '<div     class="boxes"><h1>Standard Deviation</h1></div>', '<div class="boxes"><h1>Averages</h1></div>');

    echo $subtitle[$title];
 ?>
<form method="post" action="">
      <input type="submit" id="clickies" name="clickies" value="submit" />
</form>

你可以使用php的会话。

如何通过单击更改数组值？
