I'm trying to come up with a solution, where if a div is empty, I would like to add a class so that I can display:none;. I tried searching without any luck.

I don't know how to write this expression though? Any help would be appreciated :)



<div class="<?php echo '$hiddenclass'; ?>">
<?php
echo $errors['amount'];
echo $errors['weight'];
echo $errors['date'];
echo $errors['time'];
?>
</div>

I don't really know what you're doing... but what if it was more like this:

<?php if ( empty($errors) ) {
// do nothing
} else { ?>
<div class.....

I have a div that contains all my errors on a form. I have it styled and positioned where needed, but when there are no errors, I would like the div to not be visible.

I'm going to see if I can work with the idea above, thanks.

Well that's not going over too well lol. I tried writing that function ( I always get mixed up about the names of php [statements/expressions/functions]) outside the div, inside the class="" itself and lots of different ways, I could never get it to work. I think I was doing it wrong, but not sure?

TheDoc

I'm not the strongest with PHP, so my solution might not be EXACTLY what you need to write.

Thanks for trying @TheDoc.

Even with my limited knowledge, there has to be something we can do! What code did you try?

Sweet, I asked a buddy and he helped out. I was thinking of it the same way and trying like you said, if empty do not display vice if not empty display.



<?php 
if(!empty($errors)){
echo '<div id="error-container">';
echo $errors['example'];
echo '</div>';
}
?>

wait, if you're using php why have an empty div in the first place? use php to output the div only when there is an error

TheDoc

I think that's what he finished with there.

yup, that'll teach me not to refresh the page after having a cup of coffee...
