[SOLVED] Code problem?

[wwfc_barmy_army]

Hello everyone, i have this code:

 

$result = mysql_query("SELECT * FROM user WHERE user_id = $user_id") 
or die(mysql_error());  

while ($qry = mysql_fetch_array($result))
{ 
while ($i <= $rowcount){
$result3 = mysql_query("SELECT * FROM type WHERE type_id = $i") or die(mysql_error());
$qry3 = mysql_fetch_array($result3);
$isvalue = $qry[$i];
echo $isvalue;
if (isset($isvalue) || $isvalue != "" || $isvalue != " "){	
echo "<img src='images/" . $qry3['imgurl'] . "'/> " . $qry[$i] . "<br/>";
} else {
echo "nothing";
}
$i = $i + 1;
}
}

 

When run it echos the "<img... etc", although for some reason if there isn't a value for one record in the database it will still print it, any ideas?

 

thanks.

i believe its to do with the line..

 

if (isset($isvalue) || $isvalue != "" || $isvalue != " "){

 

im sure theres another way to use the || command.... im on my pda right now though so hopefully someone else can help.

use && instead of || but if your DB returns a null value then you'll have to check for that as well.

Ahh the && worked! Thanks guys.
