Javascript php mail（）在填写表单之前发送邮件

javascript php html

Javascript php mail（）在填写表单之前发送邮件,javascript,php,html,Javascript,Php,Html,我有一个自我发布文档，它有表单字段，可以在同一文档上用php处理来填写。我的问题是，在打开页面（网站）时，“message Sent！”消息会在表单填写信息之前立即显示。php mail（）函数链接到我的电子邮件帐户，因此我可以从电子邮件中获取表单数据。但是没有发送数据，因为电子邮件是在填写表格之前发送的。我希望能够在电子邮件发送前填写表格，以便表格发送实际信息。我研究过这个话题，什么也没想到。任何帮助都会很棒！这是我的密码 <?php foreach($_POST as $key

发生这种情况是因为您尚未创建表单并要求用户提供输入。您需要做的是创建表单，然后检索表单值，并在提交表单时发送邮件。这肯定会起作用。…
首先检查提交的内容，如
$\u POST['Email Address']
或使用
if
子句的内容。这会阻止文档发送电子邮件，并允许我在发送电子邮件之前填写表单。但现在它不让我提交信息。我可以点击提交，但什么也没发生。我知道这个按钮是有效的，因为当我单击它而不填写任何表单字段时，表单会要求您填写一个字段，因为我已经验证了表单。奇怪的东西！你让我走上了正确的道路。因为你的代码让我更进一步，我知道你对isset的看法是正确的，所以我做了更多的研究。我发现这是一个错误的isset。我使用了isset（$_POST[]），效果非常好。谢谢你的帮助，让我走上正确的道路！您可以使用
$\u POST[]
完整地表示POST数组，当您使用
$\u POST['form\u element\u index']
时，表示您正在检查表单中的单个html元素，这就是区别。@RobinJennings:如果你认为答案对你有帮助，请接受并向上投票。我单击了“喜欢”按钮，它说它被录制了，但由于我的声誉很低，所以不会显示类似的内容。我使用了，如果（isset（$_POST['submit']）{，它就像一个符咒一样有效！

if( isset($_REQUEST['form_element_index']) )
{
     // Above code here
     // Now the code executes when form is submitted 
}
