我的Code大概如下：
我要如何确定Submit过后，checkbox全部是uncheck的？（我在Submit过后的页面，按 F5；Checkbox全Check！！！）
谢谢！！！

<?php
  session_start();
  $_SESSION['Name'] = $_POST['Name'];
  $_SESSION['sex'] = $_POST['sex'];
  $_SESSION['Code'] = $_POST['Code'];
$_SESSION['good'] = $_POST['good'];
?>

<meta http-equiv="Content-Type" c>
<head>
<body>
<?php
      function CheckBoxValue($chekboxvalue) {

            if (isset($_POST["hobby1"])) {

                     $ArrayOfSelection = $_POST["hobby1"];

                     for ($x = 0; $x < count($ArrayOfSelection); $x++) {

                              if ($ArrayOfSelection[$x] == $chekboxvalue) {
                                    echo ("CHECKED");
                                    break;
                              }

是吗？我拷贝你的程式，但是我submit后，按F5没有你所谓的uncheck，而是停留在submit过后应该停留的页面。

还有，Goods的field只有(A)能retrieve你所填的资料，(B)retrieve不到哦。

对啦！这只是我原来的Code大概而已，所以不是很详细。我的问题是每当我Submit过后(already insert to Database)，然后我按F5（检查是否有相同的资料 - Validation), 过后回到主页。那个Checkbox 会全部Tick；我要如何解决这个问题呢？谢谢!

在你的Code里：

<?php if (isset($hobby[0])) echo "checked"; ?>

就是说，如果isset($hobby[0]) 就会 checked。那么你可以double check 看到底isset($hobby[0])是 true 还是 false噢。

或者不要用isset，用别的，比如 empty()，或$hobby[0] == NULL，看看行吗？
