Author bio Social Links

Question

I'm using simple code to show user social link in author bio. in functions.php

<?php
function add_remove_contactmethods( $contactmethods ) {
    // Add Twitter
    $contactmethods['twitter'] = 'Twitter';
    //Add Facebook
    $contactmethods['facebook'] = 'Facebook';
 // Remove Contact Methods
    unset($contactmethods['aim']);
    unset($contactmethods['yim']);
    unset($contactmethods['jabber']);

    return $contactmethods;
}
add_filter('user_contactmethods','add_remove_contactmethods',10,1);
?>

in single.php

   <a href="<?php the_author_meta('twitter'); ?>" title="Twitter" target="_blank" id="twitter"><img src="/images/twitter.png" alt="Twitter" /></a>

so how can i hide social link in author bio when the field is empty in user profile.

please help me...

Answer 1

You need to check, if the field is empty or not before printing link using the get_the_author_meta function.

<?php if(!empty(get_the_author_meta('twitter'))) { ?>
   <a href="<?php the_author_meta('twitter'); ?>" title="Twitter" target="_blank" id="twitter"><img src="/images/twitter.png" alt="Twitter" /></a>
<?php } ?>

or, try

<?php if(!empty(get_user_meta(get_the_author_meta('ID'),'twitter'))) { ?>
   <a href="<?php the_author_meta('twitter'); ?>" title="Twitter" target="_blank" id="twitter"><img src="/images/twitter.png" alt="Twitter" /></a>
<?php } ?>

but, for some reasons, followed code fixed it

<?php if(strlen(get_the_author_meta('twitter')) >5) { ?>
   <a href="<?php the_author_meta('twitter'); ?>" title="Twitter" target="_blank" id="twitter"><img src="/images/twitter.png" alt="Twitter" /></a>
<?php } ?>
