从内部（第二级）页面提交表格答案

【问题标题】：Submitting form from interior (2nd level) pages从内部（第二级）页面提交表格

【问题描述】：

我的网站页脚中有一个使用 PHPMailer 的联系表格。所以它显示在所有页面上，因为它是模板的一部分。它在“顶级”页面（即 www.mywebsite.com/index.html）上完美运行，但在内部（或二级页面，即 www.mywebsite.com/pricing/basic.html）上它不发送。控制台说它找不到位于我的站点目录根目录中的“contact.php”文件。

我尝试添加“../contact.php”作为表单操作以向上移动，但仍然找不到。

【解决方案1】：

这听起来与此脚本中的内容无关，而与从何处加载有关。尝试将表单操作指向绝对路径而不是相对路径，即action="/contact.php" 而不是相对路径action="contact.php" 或action="../contact.php"。这样，无论从哪里提交，它都会始终指向同一个脚本。

与您描述的问题不同，这行看起来很可疑：

require 'PHPMailer-master/vendor/autoload.php';

这表明您可能正在使用 PHPMailer 自己的composer.json 文件；只有在on PHPMailer 上工作时才应该使用它，而不仅仅是在项目中使用它。您通常希望 vendor 文件夹和 composer.json 文件位于您自己项目的顶层，并且 PHPMailer 的文件会被 composer 放入 vendor/phpmailer - 尽管您不必关心这一点，因为vendor/autoload.php 会弄清楚的。请阅读自述文件，了解如何使用 Composer 在您自己的项目中安装 PHPMailer。
