Question

我有一个简单的表单，当我提交时，重定向回homepic.php（包括）。我在localhost上使用wamp服务器。这与它有什么关系吗？表格信息将通过电子邮件发送给收件人，我尚未编码。这是代码：

<?php
$field_name = $field_email = $field_message = "";
$nameError = $emailError = $messageError = "";
if ($_SERVER["REQUEST_METHOD"] == "POST"){
    if (empty($_POST["cf_name"])) {
    $nameError = "Name is required";}
    else{$field_name = test_input($_POST['cf_name']);
    if (!preg_match("/^[a-zA-Z ]*$/",$field_name)) {
      $nameError = "Only letters and white space allowed";
    }
    }
    if (empty($_POST["cf_email"])) {
    $emailError = "Email is required";}
    else{$field_email = test_input($_POST['cf_email']);
    if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$field_email)) {
      $emailError = "Invalid email format";
    }}
    if (empty($_POST["cf_message"])) {
    $messageError = "Message is required";}
    else{$field_message = test_input($_POST['cf_message']);}

}
function test_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}
?>

<form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>" method="post">
    Your name<br />
    <input type="text" name="cf_name" value="<?php echo $field_name;?>">
    <span class="error">* <?php echo $nameError;?></span><br />
    Your e-mail<br />
    <input type="text" name="cf_email" value="<?php echo $field_email;?>">
    <span class="error">* <?php echo $emailError;?></span><br />
    Message<br />
    <textarea name="cf_message" value="<?php echo $field_message;?>"></textarea>
    <span class="error">* <?php echo $messageError;?></span><br />
<input type="submit" value="Send">
<input type="reset" value="Clear">
</form>

这是我的索引导航：

<div class="main">
    <?php switch ($_GET['page']) {
    case 'home':
    include ('homepic.php');
    break;
    case 'about':
    include ('about.php');
    break;
    case 'contact':
    include ('contact_form.php');
    break;
    case 'newwork':
    include ('ainewwork.php');
    break;
    case 'nature':
    include ('nature.php');
    break;
    case 'structures':
    include ('structures.php');
    break;
    case 'other':
    include ('other.php');
    break;
    default:
    include ('homepic.php');
    break;

    }              
    ?>

这是我的导航代码：

<nav>

     <ul id="menu">                              
        <li class="left"><a href="index.php?page=home">home</a></li>
        <li><a href="index.php?page=about">about</a></li>
        <li class="top"><a href="#">portfolios</a>
            <ul class="item"><li ><a href="index.php?page=newwork">new work</a></li>          

            <li ><a href="index.php?page=nature">nature</a></li>

            <li ><a href="index.php?page=structures">structures</a></li>               

            <li ><a href="index.php?page=other">other</a></li>
           </ul>
        </li>
        <li class="right"><a href="index.php?page=contact">contact</a></li>                 
       </ul>                
      </nav>

如果您更改开关代码以允许GET / POST变量。您可以根据您正在执行的操作定义该var。

 <?php switch ($_REQUEST['page']) {
    case 'home':
    include ('homepic.php');
    break;
    case 'about':
    include ('about.php');
    break;
    case 'contact':
    include ('contact_form.php');
    break;
    case 'newwork':
    include ('ainewwork.php');
    break;
    case 'nature':
    include ('nature.php');
    break;
    case 'structures':
    include ('structures.php');
    break;
    case 'other':
    include ('other.php');
    break;
    default:
    include ('homepic.php');
    break;

    }              
    ?>

然后在表单中，您可以像这样维护变量。

<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post">
    Your name<br />
    <input type="text" name="cf_name" value="<?php echo $field_name;?>">
    <span class="error">* <?php echo $nameError;?></span><br />
    Your e-mail<br />
    <input type="text" name="cf_email" value="<?php echo $field_email;?>">
    <span class="error">* <?php echo $emailError;?></span><br />
    Message<br />
    <textarea name="cf_message" value="<?php echo $field_message;?>"></textarea>
    <span class="error">* <?php echo $messageError;?></span><br />
    <input type="hidden" name="page" value="<?php echo $_GET['page']; ?>" />
<input type="submit" value="Send">
<input type="reset" value="Clear">
</form>

简单的形式不会在wamp服务器上发布
