I tried and had no issue with $_POST[].
Have you tried print_r($_POST); to ensure it is a $_POST variable problem.
Can you post a snippet of code that duplicates this problem?
Here is what I did:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Untitled Document</title>
</head>
<body>
<?php
if($_POST['action'] == 'submit'){
echo "print_r: ";
print_r($_POST);
echo "<br>";
echo "post: ".$_POST["fieldname"];
$var = $_POST["fieldname"];
echo "<br>var: ".$var;
}
?>
<form name="form1" method="post" action="<?php echo
$HTTP_SERVER_VARS['PHP_SELF'];?>">
<table width="400" border="1" align="center" cellpadding="0"
cellspacing="0">
<tr>
<td width="50%" align="right">Field:</td>
<td><input name="fieldname" type="text" id="fieldname"></td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
<tr align="center">
<td colspan="2"><input type="submit" name="Submit" value="Submit">
<input name="action" type="hidden" id="action" value="submit"></td>
</tr>
</table>
</form>
</body>
</html>
