ternary operator sintax help

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

<?= (isset($erros['anexo'])) ? '<div class="mensagemErro">'
.$erros['anexo'].'</div>' :''; ?>

:( 

Can I have your help with the right syntax ?


Regards,
The newbie on a Humpty Dumpty wall,
Márcio
