[NoDoze]

if (isset($row['murl']))
echo "<a href=".$row['murl'] . ">more info</a>";
else
echo "<a href=".$row['mhover'] . ">more info</a>";

 

I think this is correct....but if the variable isn't present, it's NOT showin the mhover URL....what am I doing wrong?

 

I'm trying to do...

 

If variable is pesent in DB

do THIS

ELSE

Do THAT

 

Thanks!

Well a variable will always be set unless the DB doesn't have that column. Try using empty instead.

as ken2k7 noted, as long as you select the column $rows['murl'] will always be set. you need to know its value. try using is_null and empty. something like...

 

if (is_null($row['murl']) || empty($row['murl'])) {
  ...
} else {
  ...
}

First of all if is_null($var) is true, then empty($var) is true. There's no need to call both, especially when it's an OR statement.

yep. just re-read the man page for empty. sum-bitch. been coding redundancy into my first php app already. thanks for the info. gonna have to fix that in the next iteration.
