Get back a value from a field ....

Hi, I don't know if my title is very understandable .... sorry :hurt:

I've a problem with a new hack I'm finishing ....

So, I'd like to get back a value from a field and compare it to something

I've in my table thread a fiel called adresse_icone and I'd like to get back this value for a special thread and compare it to an other value .... hum :alien: , I don't think I'm understandble

That's what I'd like to do :

PHP Code:

$threadadr=$DB_site->query_first("SELECT adresse_icone FROM thread WHERE threadid='$threadid'"); 

if (($threadadr)!=('')) 
{ 
$img="<img src="; 
$alt="alt="; 
$fin=">"; 
} 

in the global.php file to get back $img, $alt and $fin in the template forumdisplay_threadbit

If the field is empty, I don't want to do it

The query doesn't seem to be good ... Help me plizzzzzz

use this instead:

PHP Code:

$threadadr=$DB_site->query_first("SELECT adresse_icone FROM thread WHERE threadid='$threadid'"); 

if (trim($threadadr['adresse_icone'])!='') 
{ 
$img="<img src="; 
$alt="alt="; 
$fin=">"; 
}
