validating on a string. 1

[Nightsoft]

I have this little piece of code that says that if [tt]$KONVERTERNAVN[/tt] = the string which contains : KFUM-Spejderne i Danmark
But even if the [tt]$KONVERTERNAVN[/tt] is something else than KFUM-Spejderne i Danmark it still runs through this code.
The [tt]$KONVERTERNAVN[/tt] is brought by an SQL query and if i just echo the [tt]$KONVERTERNAVN[/tt] then it print's out KFUM-Spejderne i Danmark
So how can it be that even if the [tt]$KONVERTERNAVN[/tt] is something else it does it anyway ?? Any good answers?

My code :
[tt]

/* some SQL code before this. */

if($KONVERTERNAVN = "KFUM-Spejderne i Danmark")
{
  $mail = "korpskontor@kfumscout.dk";
  echo '<script language=&quot;javascript&quot;>winopen(\'mailform.php?modtmail='.$mail.'\')</script>';
}

you are using the assignment operator in the line
if($KONVERTERNAVN = "KFUM-Spejderne i Danmark&quot


You will want to change that to:
if($KONVERTERNAVN == "KFUM-Spejderne i Danmark&quot
to change it to a comparison operation.

Thank you very much.!

What's the difference on the == and the =
Where would one use just a single = ?

a single = is an assignment operator. It means "left operand gets set to the value of the expression on the rights"

double == is a comparison operator. It is asking the question: Is the left operand equal to the right operand?

Hope this helps
