User Social Profiles

To use this plugin – your theme (or child theme) must support it.
To display additional profiles for user you just need to use native WordPress function the_author_meta( 'profile-name' ) where ‘profile name’ can be ‘twitter’, ‘facebook’, ‘googleplus’, ‘instagram’, ‘pinterest’.

Code example (with Font Awesome Icons):

<?php
    $prefix_twitter_url = get_the_author_meta( 'twitter' );
    $prefix_facebook_url = get_the_author_meta( 'facebook' );
    $prefix_googleplus_url = get_the_author_meta( 'googleplus' );
    $prefix_instagram_url = get_the_author_meta( 'instagram' );
    $prefix_pinterest_url = get_the_author_meta( 'pinterest' );
?>
<?php if ( ! empty( $prefix_twitter_url ) ) : ?><a href="<?php the_author_meta( 'twitter' ) ?>"><span class="fa fa-twitter"></span></a><?php endif; ?>
<?php if ( ! empty( $prefix_facebook_url ) ) : ?><a href="<?php the_author_meta( 'facebook' ) ?>"><span class="fa fa-facebook"></span></a><?php endif; ?>
<?php if ( ! empty( $prefix_googleplus_url ) ) : ?><a href="<?php the_author_meta( 'googleplus' ) ?>"><span class="fa fa-google-plus"></span></a><?php endif; ?>
<?php if ( ! empty( $prefix_instagram_url ) ) : ?><a href="<?php the_author_meta( 'instagram' ) ?>"><span class="fa fa-instagram"></span></a><?php endif; ?>
<?php if ( ! empty( $prefix_pinterest_url ) ) : ?><a href="<?php the_author_meta( 'pinterest' ) ?>"><span class="fa fa-pinterest"></span></a><?php endif; ?>
