如何消除此脚本中 die() 的使用，以便底部的 HTML 仍然运行？

发布于 2024-11-18 12:39:16 字数 5557 浏览 2 评论 0原文

当我最初编写这个脚本时，站点设计不需要在 die() 函数之后执行 html。现在确实如此。我意识到我可以将 HTML 代码的末尾复制到每个 die() 语句中，但它包含一个 php 包含文件 (footer.inc.php)，然后该文件会被忽略。 （这是我目前正在使用的解决方法，因此页面看起来不错，但不包含页脚。）

我尝试将第一个序列中的 die() 函数切换为 if() 和 elseif() 函数，但是然后它会显示 die() 消息以及电子邮件代码后面的消息，表明电子邮件功能成功。

我确信有一种方法可以让脚本只执行其中一个语句而不使用 die()，但我无法弄清楚。任何提示将不胜感激！

原文

When I initially wrote this script, the site design did not require the execution of the html after the die() functions. Now it does. I realize I can copy the end of the HTML code into each of the die() statements, but it contains a php include file (footer.inc.php) which is then ignored. (This is the workaround that I am going with at the moment, so the page looks OK but does not contain the footer.)

I tried switching the die() functions in the first sequence to if() and elseif() functions, but then it displays both the die() message and the message after the email code that indicates the email function was successful.

I am sure there is a way to have the script execute only one of these statements without using the die(), but I can't figure it out. Any tips would be greatly appreciated!

您可以构建一个 $error 变量并在尝试发送电子邮件之前检查它。大致如下：

$error = '';
//validate sumbitted data
if (empty($name)){
    $error .= '<p class="center">Please provide your name.</p>';
}

if (empty($email)){
    $error .= '<p class="center">Please provide your email.</p>';
}

// etc...

if (empty($error)) {
    //formulate email message
    $to = '[email protected]';
    $from = 'centercourtstringing.com';
    $subject = 'Contact from centercourtstringing.com';

    // etc...

    if (mail($to, $subject, $body, "From $from")) {
        echo '<p>Your pick-up has been requested...</p>';
    } else {
        die('<p>Sorry, there was a mail delivery error...');
    }
} else {
    echo $error;
    echo '<form><p class="center"><input type="button" value="Go back" onClick="history.go(-1);return true;"> </p></form>';
}

// Rest of HTML

You can build an $error variable and check it before attempting the email. Something along the lines of:

$error = '';
//validate sumbitted data
if (empty($name)){
    $error .= '<p class="center">Please provide your name.</p>';
}

if (empty($email)){
    $error .= '<p class="center">Please provide your email.</p>';
}

// etc...

if (empty($error)) {
    //formulate email message
    $to = '[email protected]';
    $from = 'centercourtstringing.com';
    $subject = 'Contact from centercourtstringing.com';

    // etc...

    if (mail($to, $subject, $body, "From $from")) {
        echo '<p>Your pick-up has been requested...</p>';
    } else {
        die('<p>Sorry, there was a mail delivery error...');
    }
} else {
    echo $error;
    echo '<form><p class="center"><input type="button" value="Go back" onClick="history.go(-1);return true;"> </p></form>';
}

不要使用 die()，因为它被编程为阻止整个脚本运行。相反，您应该使用 echo 或 print 方法在屏幕上显示内容。

示例：

<div id="phpscreen">
     <?
     //validate sumbitted data
     if (empty($name)) {
         echo '<p class="center">Please provide your name.</p> <form><p class="center"><input type="button" value="Go back" onClick="history.go(-1);return true;"> </p></form>';
     }
     else if (empty($email)) {
          ...
     }
     ....
     else {
         if(mail($to, $subject, $body, "From $from")) {
              ...
         } 
         else {
              ...
         }
     } ?>
</div>

然后对所有其他检查使用“else if”。否则，如果您不填写 10 个字段，您将显示 10 个表格。 :)

Simply do not use die() because it is programmed to stop your entire script from running. Instead, you should use either the echo or print method to display content on your screen.

Example:

<div id="phpscreen">
     <?
     //validate sumbitted data
     if (empty($name)) {
         echo '<p class="center">Please provide your name.</p> <form><p class="center"><input type="button" value="Go back" onClick="history.go(-1);return true;"> </p></form>';
     }
     else if (empty($email)) {
          ...
     }
     ....
     else {
         if(mail($to, $subject, $body, "From $from")) {
              ...
         } 
         else {
              ...
         }
     } ?>
</div>

And then use "else if" for all the other checks. Else you will show 10 forms if you do not fill in 10 fields. :)

将您的 if 和 邮件发送 语句更改为 if-elseif-else 块

//validate sumbitted data
if (empty($name)){
    echo('<p class="center">Please provide your name.</p> <form><p class="center"><input type="button" value="Go back" onClick="history.go(-1);return true;"> </p></form>');
}
elseif (empty($email)){
    echo('<p class="center">Please provide your email.</p> <form><p class="center"><input type="button" value="Go back" onClick="history.go(-1);return true;"> </p></form>');
}
//... other validation conditionals...

//None of the above conditionals are true, send the message.
else
{

   $to = '[email protected]';
    $from = 'centercourtstringing.com';
    $subject = 'Contact from centercourtstringing.com';
    $body = "

Change your if and mail sending statements into an if-elseif-else block

//... other validation conditionals...

//None of the above conditionals are true, send the message.
else

   $to = '[email protected]';
    $from = 'centercourtstringing.com';
    $subject = 'Contact from centercourtstringing.com';
    $body = "
