[Resolved] checking if isset

[g7ibby]

a3t is the 10th feild in my table
That table row is populated only to the the 9th field.

I want my script to check if a feild contains data
If it does the do this.
If not move to the next feild to check that one.

$result = mysql_query("SELECT * FROM table",$db);
	while ($myrow = mysql_fetch_array($result))
{

if (isset($myrow["a3t"])){
printf ("<tr><td>\n");
echo "string is set";
//printf ($myrow["question"]);
printf ("</td></tr>\n");
}
else{
printf ("<tr><td>\n");
echo "string is NOT set";
printf ("</td></tr>\n");
}
}

if I change where is says

if (isset($myrow["a3t"])){

to

if (isset($myrow["a1t"])){

I should get string is set sent back to me since it does contain data.

Where might I be going wrong???

try is_null() instead, since isset() will come back true even if there is "" in the database, isset() is usually used to see if, say, a submit button is pushed
