try this, use $_POST array in foreach:
action.php
foreach ($_POST as $key => $value)
echo "Field ".htmlspecialchars($key)." is ".htmlspecialchars($value)."<br>";
i hope it will be helpful.

what if i have in my form several input that i wish to get elements form by post like :
<form method="post" action="action.php"><input type="submit" name="'.$name.'"> <input type="text" name="'.$course.'"</form> ?you can simply put it like
$_POST["{$name}"];
or
you can concatenate it like
$_POST['abc_'.$name];
To make it more clear See http://www.php.net/manual/en/language.types.string.php

Try this.
$name = 'name';
$var = $_POST[$name];
The result will display the value of the name variable.

Try This: print_r($_POST);
This is print all values with parameter.

This is just print all parameters.
I figured out how to do it .
<form method="post" action="action.php"><input type="hidden" name="name" value="'.$name.'">
action.php: $var=$_POST['name']; echo $var;
it displays the value of the input which is $name.
input can be whatever you want !!
$namevariale will come
