Question

我是PHP的新手，我正在尝试创建一个表单，当用户填写时，会重定向到我的成功页面，然后启动下载并将其详细信息保存到.txt文件中。

我已设法完成上述所有操作，但未重定向用户，但仍会运行下载文件的代码（位于成功页面中）。

为什么会这样？

如果我删除了下载文件的代码，那么用户被重定向，我是否需要在文件下载之前添加延迟？

Answer 1

success.php是一个下载。您的浏览器不会重定向到下载，它只会下载它。您需要将下载代码移动到另一个文件 - 比如download.php，然后重定向到该文件。拥有“下载报告”按钮而不是自动下载可能是更好的用户体验。

标题（ “位置：success.php”）;运行位置代码而不是重定向
