I would try:
if (isset($fieldname) && empty($fieldname)){
// do something here with the variable
} else {
$fieldname="na";
} // if (isset($fieldname) && empty($fieldname))

Subject: [PHP] check null value
If I have one input text box that when it is submitted to next page, I want
to check first if it is nothing, then write "na" on next page, else just
echo whatever it is, is it correct to do this?
if ($fieldname == ""){
$fieldname ="na";
}
...
(then come to the html bit below)
<td><?php echo $fieldname ?></td>
I wonder specificly about the check if it is null part if it is corerct. Any
thoughts?
Jack
