Question

您好我正在创建一个简单的宣传册申请表，以捕获用户的品牌和价格信息以及他们的电子邮件ID。我为三个页面创建了代码（Page1.php用于品牌选择，Page2.php用于价格范围和电子邮件地址。我在下一页获得用户选择的page1.php值，但我没有在邮件页面中获取值（我需要在这里收集这两个页面值并提交给电子邮件）。请在下面找到页面代码。请帮忙。

page1.php中

<html>
<body  bgcolor="#fff" text="#000" >
<form method="post" action="page2.php">
<p>Which car you want to buy?<P>
<TABLE border="1" width="500">
<TR ><TD><input type="checkbox" value ="ferrari"  name="brand[]"><TD>Ferrari</td></TR>
<TR><TD><input type="checkbox" value ="mercedes"  name="brand[]"><TD>Mercedes</td></TR>
<TR><TD><input type="checkbox" value ="bugatti"  name="brand[]"><TD>Bugatti</td></TR>
</TABLE>
<input type="hidden" value="1" name="car_brand" >

<input type="submit" value="Continue" >

Answer 1

检查每页的以下代码

第1页

<html>
<body  bgcolor="#fff" text="#000" >
<form method="post" action="page2.php">
<p>Which car you want to buy?<P>
<TABLE border="1" width="500">
<TR ><TD><input type="checkbox" value ="ferrari"  name="brand[]"><TD>Ferrari</td></TR>
<TR><TD><input type="checkbox" value ="mercedes"  name="brand[]"><TD>Mercedes</td></TR>
<TR><TD><input type="checkbox" value ="bugatti"  name="brand[]"><TD>Bugatti</td></TR>
</TABLE>
<input type="hidden" value="1" name="car_brand" >
<p>
<input type="submit" value="Continue" >
</form>
</body>

2页

在这个页面中，我使用了implode函数将数组转换为字符串

<html>
<body  bgcolor="#fff" text="#000" >

<div id="firstpage-value" style="border:1px solid #000;">
<h4>Selected Brand</h4>
<?php
if(isset($_POST['car_brand']))
{   
    $count=count($_POST['brand']);
    for($i=0;$i<$count;$i++)
    {
        echo $_POST['brand'][$i]." ";
    }
    $brand = implode("," ,$_POST['brand']);
}
?>
</div>

<form method="post" action="mail.php">
<p>Choose a Price Range<P>
<TABLE border="1" width="500">
<TR ><TD><input type="checkbox" value ="under20k"  name="price[]"><TD>Under $20K</td></TR>
<TR><TD><input type="checkbox" value ="35-85k"  name="price[]"><TD>$35K-$85K</td></TR>
<TR><TD><input type="checkbox" value ="over85k"  name="price[]"><TD>Over $85K</td></TR>
</TABLE>
<input type="text" name="email" value="email" />
<input type="hidden" value="1" name="car_price" >
<p>
<input type="submit" value="Submit" >

<input type="hidden" name="brand" value="<?php  echo $brand; ?>">
</form>
</body>
</html>

邮件页面

<?php 



/* Subject and email variables */

$emailsSubject = 'Brochure Request';
$thanks = 'Thank you for requesting Brochure';
$webMaster  = 'mailsample@gmail.com';
$mailheader .= "Reply-To: ".$_POST["email"]."\r\n";

//Get the input.
 $email = $_POST['email'];
$brand = $_POST['brand'];
$price = implode(",",$_POST['price']); 


$body = '
<p>A user has been submitted "Request Brochure" form with the following info.</p>
<table width="600" border="1" >
      <tr>
      <th width="556" height="37" align="left"><h2>Which car you want to buy?</h2></th>
      <th width="268" style="border-bottom:1px solid #ccc; ">'.$brand.'</th>
    </tr>
    <tr>
      <th width="556" height="37" align="left"><h2>Choose price range</h2></th>
      <th width="268" style="border-bottom:1px solid #ccc; ">'.$price.'</th>
    </tr>

    <tr>
      <th width="556" height="37" align="left"><h2>Email Address</h2></th>
      <th width="268" style="border-bottom:1px solid #ccc; ">'.$email.'</th>
    </tr>   
    ';


    $headers = "From: $email\r\n";
$headers .= "Content-type: text/html\r\n";
$headers .= 'Cc:'. $email . "\r\n";
$reply = "";

/* This is what sends the email */
$success = mail($webMaster, $body, $headers, "-f $email");


/* Results Rendered as Html */



header('location:thankyou.php');exit;
?>

Answer 2

此处有太多信息要发表评论。你可以记住一些事情。首先：

检查POST请求

仔细检查处理请求的页面上是否有有效的POST请求，现在您只是假设第2页上有任何请求。这样您就可以确定您需要的数据。例如，在page1.php上命名您的按钮：<input type="submit" name="step1" value="Continue" />，现在您可以在第2页上验证按下此按钮：

if( isset( $_POST['step1'] )) 
{
    // Process your code, otherwise return to page1
}

验证发送到下一页的数据

通过检查发送的数据，确保您从上一页收到正确的数据。您可以使用简单的var_dump()执行此操作。如果将var_dump（）包装在<pre>标记内，它会为您提供更好的可读结果。例如：

if( isset( $_POST['step1'] )) 
{
    echo '<pre>'; var_dump($_POST); echo '</pre>';
}

使用内爆并爆炸

您在第2步中将$ _POST [＆＃39;品牌＆＃39;]回复到文本字段，这是不可能的，因为$ _POST [＆＃39;品牌＆＃39;]是PHP数组。你可以做几个选项，最简单的就是使用implode()，这个函数会破坏一个数组并返回一个字符串：

if( count($_POST['brand']) > 0 ) {
    $brands = implode(",", $_POST['brand']);  // returns: ferrari,mercedes,bugatti
}

要将此字符串返回到数组，您可以使用explode(",", $brands);

全部应用并调试

应用这些内容，验证每个帖子的请求并调试出错的地方和位置。这些简单的步骤将使您的脚本尽快运行。您的脚本还需要学习和改进很多东西。但是现在让我们通过这些提示离开它。

Answer 3

问题出在page2.php上在这里，您要将数组转换为第<input type="hidden" name="brand" value="<?php echo $_POST['brand']?>">行

的字符串

解决此问题的一个简单方法是，您可以使用implode函数将所有选定的品牌转换为逗号分隔字符串，然后将该字符串分配给隐藏输入的值，以便您可以在邮件中访问它。 php页面。

$brand = '';
if(isset($_POST['brand']))
{   
    $brand = implode("," ,$_POST['brand']);
}

然后

<input type="hidden" name="brand" value="<?php echo $brand; ?>">

通过多个页面传递复选框值并使用php发送电子邮件

3 个答案:

验证发送到下一页的数据
