isset help!

[chard]

Hi guys,

 

Not sure if this is the right syntax but I'm a bit lost.

 

This is what i'm doing:

 

if(!isset($a,$b,$c))

{ //line 23

 

something

 

}

The error I'm getting is:

Parse error: syntax error, unexpected '{' in /home/mytest/public_html/mtun.php on line 23

if(!isset($b) ||!isset($c) ||!isset($a)){

//

}

oops you use $variables right? so i guess better to use empty

if(!empty($b) ||!empty($c) ||!empty($a)){

//

}

 

i guess checking using isset is better for post , get , session , ect..

There shouldn't be an exclamation before empty.  It should simply be

if(empty($a) && empty($b) && empty($c))
{ //line 23

something

}

 

But to decide whether it is && or ||, we need to know what you are trying to evaluate.
