如何修改 formmail 以便错误页面仍然发送、电子邮件和重定向？

发布于 2024-09-25 09:29:15 字数 7757 浏览 8 评论 0原文

到目前为止，它提交了电子邮件，但无论我做什么，它都不会重定向（服务器错误），我需要将其重定向到自定义错误页面。

我将如何修改它以使其工作？

原代码：

# If any error fields have been found, send error message to the user.   #
    if (@error) { &error('missing_fields', @error) }

新代码：

    if (@error) { # Print HTTP header and opening HTML tags.                           #
        print "Content-type: text/html\n\n";
        print "<html>\n <head>\n";

        # Print out title of page                                            #
        if ($Config{'title'}) { print "<title>$safeConfig{'title'}</title>\n" }
        else                  { print "<title>Thank You</title>\n"        }

        print " </head>\n <body";

        # Get Body Tag Attributes                                            #
        &body_attributes;

        # Close Body Tag                                                     #
        print ">\n  <center>\n";

        # Print custom or generic title.                                     #
        if ($Config{'title'}) { print "<h1>$safeConfig{'title'}</h1>\n" }
        else { print "<h1>Thank You For Filling Out This Form</h1>\n" }

        print "</center>\n";

So far it submits the email but no matter what I do it will not redirect (server errors) and I need to redirect it to a custom error page.

How would I modify this to make it work?

Original code:

# If any error fields have been found, send error message to the user.   #
    if (@error) { &error('missing_fields', @error) }

new code:

    if (@error) { # Print HTTP header and opening HTML tags.                           #
        print "Content-type: text/html\n\n";
        print "<html>\n <head>\n";

        # Print out title of page                                            #
        if ($Config{'title'}) { print "<title>$safeConfig{'title'}</title>\n" }
        else                  { print "<title>Thank You</title>\n"        }

        print " </head>\n <body";

        # Get Body Tag Attributes                                            #
        &body_attributes;

下面的代码在第 805 行工作：

    print "Location: " . &clean_html($Config{'missing_fields_redirect'}) . "\n\n";
&send_mail;

然后将其添加到表单中

<input type="hidden" name="missing_fields_redirect" value="http://www.example.com">

，但就像评论所说，最好更新到 TFMail （我很快就必须自己做）

the below worked at line 805:

    print "Location: " . &clean_html($Config{'missing_fields_redirect'}) . "\n\n";
&send_mail;

and then add this in the form

<input type="hidden" name="missing_fields_redirect" value="http://www.example.com">

but like the comments say, it would be best to update to TFMail (which i will have to do myself shortly)
