Hide text if echo is blank

[yvon]

Hello

Im a newbie on php but i like to change a small part of the code.

<p><strong>telefoon:</strong> <?php  echo get_the_author_meta('telefoon', $curauthID); ?></p>

I would like to hide telefoon: if the echo command get_the_autor_meta is empty

First please use the code icon (<>) at the top of the menu for your code and specify PHP.

<?php
$tele=get_the_author_meta('telefoon', $curauthID);
attrib=""
if (empty($tele)){
   $attrib="hidden"
}
echo "<p $attrib><strong>telefoon:</strong>$tele</p>";
?>

Untested.

FYI - the code above is missing a couple of semicolons

Note how the code was written without leaving PHP mode and thus avoids the messy way of having to code your p tag so clumsily.  

AND - if this is not the sole contents of your php script then leave out the ?> tag.  It is not required nor is it needed to end a script.  Entering and leaving php mode is not a practical way of coding a php script.  Sure - you may have some block of JS code so you can do it but when all you are doing is running php logic and then assembling php results with html code use the echo and double quotes and avoid the in-and-out style of coding php results.  Just my $.02

Sorry. Corrected code.
