PHP 按“发送”后变量未打印出来
PHP variable not printing out after pressing 'Send"
在我的联系表单中,我想在用户按下 "Send" 按钮后在容器底部显示“"Message sent, thank you for contacting us!"。我已将 php 变量包含在 div 标记在我的 HTML 中。但是当我按下发送时,它会转到一个空白页面,而不是停留在同一页面上并显示消息。可能是什么问题?

我已经测试过,它正在运行,请查看以下屏幕,我只是添加了一个正确的文件名并且它可以运行。
在我的联系表单中,我想在用户按下 "Send" 按钮后在容器底部显示“"Message sent, thank you for contacting us!"。我已将 php 变量包含在 div 标记在我的 HTML 中。但是当我按下发送时,它会转到一个空白页面,而不是停留在同一页面上并显示消息。可能是什么问题?
