在哪里把验证代码的PHP表单验证

如果我正在做用户输入的表单验证，我必须把phpcode的形式正确的页面？在哪里把验证代码的PHP表单验证

也在<form>标记中，我必须指定任何东西。我的意思是，如果出现错误，用户将不得不返回到出现错误的相同输入页面。如果它是成功的输入，用户应转到订单process.php

PHP验证码：

<?php 
$name = $_POST['name']; 
$nameregex = '/^[a-zA-Z]+\s?[a-zA-Z]+$/'; 
if (!preg_match($nameregex, $name)) { 
    echo '<font color=red>Please enter a valid name</font>'; 
} 
$email = $_POST['email']; 
$emailregex = '/^[a-zA-Z\_\-\.0-9]+\@[a-zA-Z\_\-\.0-9]+$/'; 
if (!preg_match($emailegex, $email)) { 
    echo '<font color="red">please Enter a valid email id</font>'; 
} 
$address = $_POST['address']; 
$addressregex = '/^[0-9a-zA-Z\,\s]+$/'; 
if (!preg_match($$addressregex, $address)) { 
    echo '<font color="red">please Enter a valid Address</font>'; 
} 
$state = $_POST['state']; 
$stateregex = '/^[a-zA-Z]+\s?[a-zA-Z]+$/'; 
if (!preg_match($stateregex, $state)) { 
    echo '<font color="red">please Enter a valid state name</font>'; 
} 
$pincode = $_POST['pincode']; 
$pincoderegex = '/^[a-zA-Z]+\s?[a-zA-Z]+$/'; 
if (!preg_match($pincoderegex, $pincode)) { 
    echo '<font color="red">please Enter a valid pincode</font>'; 
} 
?>

不是一个这个问题，但一个想法。该正则表达式不会让你输入特殊字符的名字。 Pär例如是一个瑞典名字......其他语言中也有很多其他语言。你不能使用这样的东西：http://www.w3schools.com/php/php_ref_filter.asp？ – 2012-01-07 09:01:12

+1。我是PHP的初学者，非常感谢您指出！：D – defiant 2012-01-07 09:07:25

我只写了一个项目在我的生活中的PHP和一些PHP的WordPress模板。所以也许我不是合适的人。但我只是发现发现问题;） – 2012-01-07 09:09:41

你必须把在'process-order.php'中使用php代码（用于验证）。它会收到表单数据。

那么，我怎样才能以他们输入数据的形式显示错误？或者这在PHP中是不可能的？：/ – defiant 2012-01-07 09:08:30

** process-order.php **将验证数据。如果没关系，它会_directs_到'成功'页面，如果没有，它会_directs_到表单。在表单中，您可以检查一些会话变量以检查是否有错误。但这只是一种方法。（我用这个） – 2012-01-07 09:11:00

它会去表单的ACTION（这是process-order.php）。

如果验证失败，用户将不得不返回到表单页面，所有内容都将为空。

将所有表单域再次预填所以一切不为空，你可以做，例如

<input id="pincode" name="pincode" class="text" />

变化

<input id="pincode" name="pincode" class="text" value='<?php echo (isset($_POST['pincode'])) ? $_POST['pincode'] : '' ?>' />

您可以重定向到同一页面（即订单），并根据验证结果选择显示不同的HTML内容：

<?php 
    // Validation routine here -- you can count the number of validation errors and use this as decision whether to show the form again or not 
    if ($_POST['submit']) { 

    $errorCount = 0; 

    // Validations here + count errors 


    } 
    // -- end of validation routine 

    if ($errorCount == 0) { ?> 

    <h1>Order Processed</h1> 
    <p>Your order was processed...</p> 

    <?php } 
    // If error count is above zero OR the submit button was never pressed, display form: 
    else { ?> 

    <form>...</form> 

    <?php } ?>
