Hide a div if the fiels is empty

Question

I have a problem to hide a div when the input of a custom field is empty. This is the code I am using, it's fine when the field is not empty. But when the fireld empty, the div will show.

The field that displays the content is postintro2, the div I want to hide when empty is

<div class="single2-intro">

The complete codes is:

<?php { $postintro2 = get_post_meta ($post->ID, 'postintro2', $single = true);
if($postintro2 !== '') 
echo '<div class="single2-intro">'.$postintro2.'</div>';                            
} ?>

Thanks for any helps.

Answer 1

Try:

$postintro2 = get_post_meta ($post->ID, 'postintro2', true);

if ( ! empty( $postintro2 ) ) {
     echo '<div class="single2-intro">'.$postintro2.'</div>';                            
}

From the codex: get_post_meta
