无法处理php表单

php email

无法处理php表单,php,email,Php,Email,我是一个新手，对php既老又新。 我正在努力学习php（以及其他一切），以便将其整合到web站点中。 我已经撕下了一个带有php控件的示例表单，以帮助我学习。 将HTML页面和php文件上传到我的web主机上，我发现当我按下submit“按钮”时什么也没有发生——网页上有短暂的停顿，然后是空白页面。 请有人看一下精简的php代码，并告诉我我犯了什么错误？ 非常感谢你 HTML代码： <!DOCTYPE html> <head> <meta c

整个PHP文件被一个大的
包围，如果
：


if(isset($_POST['email'])) {


但是您的表单不包含名为
email
的字段。因此，要么包含名为
email
的文本字段，要么删除
if
，要么将
if
更改为


if(isset($_POST['first_name'])) { 



由于代码似乎会生成电子邮件，因此第一个选项可能是最佳选择。
非常感谢您的回复。我所做的是将html和php剥离到我认为最小的程度（以节省空间）。如果我能够发布完整（原始）的HTML和php代码，那会有帮助吗？原始文件中有电子邮件字段。。。。。我是罪魁祸首。
