为什么我不能得到$ _post这些值？

Question

我仍然是新手,所以我对于获取跨页面内容的帖子价值感到有些不稳定.

我有一个在线应用程序,我正在制作,到目前为止它主要工作但我遇到了3个字段的问题似乎不想转移,无论我做什么.

我有其他的变量,我所看到的是完全相同的方式,工作正常,但这三个给我带来麻烦

谁能指出我做错了什么？

php代码到目前为止

$notes = $_POST["notes"];

echo "<br>experince <br>";
echo $experince = $_POST["exp"];<--------------

$education = $_POST["education"];
echo "<br>clearnce <br>";
echo $clearance = $_POST["clearance"]; <-----------------
echo "<br>jobname <br>";
echo $jobname = $_POST["jobname"];<--------------

$name = $_POST["username"];
$phone= $_POST["phone"];
$email= $_POST["email"];
$avail =$_POST["availability"];
$subject = "New Online Application: $jobname " ;
$subject .= rand(1000,9999);

如果您发布了其余的表单代码,它会有所帮助.无论如何,值得尝试的第一级调试表单是您要发布到的页面上的以下代码:

<pre>
<?php print_r($_POST);?>
</pre>

这至少会清楚说明哪些变量被发布到您的脚本中
