ternary operator sintax help

Hello all,

I'm trying to display a div, only when some php value is set.
Since this will be near html, I'd like to keep it on one line. So, I'd =
love
to use shortcuts and a ternary operator for the effect.

I'm having something like this right now, but the div still appears even =
if
the error is NOT set.

'
..$erros['anexo'].'' :''; ?>

:(=20

Can I have your help with the right syntax ?


Regards,
The newbie on a Humpty Dumpty wall,
M=E1rcio

Firstly, short tags being on, which causes all sorts of problems should you ever
need PHP to output XML.

The only reason I can see that the div will always appear is a logic
error. Are you sure that the $erros['anexo'] variable is not set at some
point and not just set to an empty string? An empty string is very
different from an unset variable. Try using var_dump($erros['anexo']);
in your code somewhere to see if the it is actually an empty string
instead.

Thanks. I will give up on =20
I have declared the erros variable like this:
=20
$erros=3Darray();
=20
Instead of isset Iâ€=99ve also tried with empty();
=20
If I have something like this, it works:
=20

RE: Re: ternary operator sintax help

Sorry all,
It's ok. The sintax:

class=3D"mensagemErro">'.$erros['anexo'].'' :''); ?>

Was right all the time.=20

Anyway, I've learn something new: having a var with '' is not the same =
thing
as not been unset. So we must pay attention on what cases we use isset, =
or
!empty.


Thanks a lot,
M=E1rcio

Another one to consider...

strlen ($item) > 0 ? 'not empty' : 'empty';

Because "empty()" will return true if 0 is the value, sometimes you =20
have to check for the length of the item.
