I put it in function.php and single.php but still not working.

Using WP 4.9 and MyCred 1.8 (beta). Already tried with 1.7.x (latest)

https://mycred.me/tutorials/awarding-points-for-users-who-share-a-post/

add_shortcode( ‘mycred_share_this’, ‘mycred_render_shortcode_share_this’ );
function mycred_render_shortcode_share_this( $attr, $link_title )
{
// Get URL (we assume you only use this shortcode inside the loop)
$url = get_permalink();

// Add affiliate link (requires myCRED 1.5.3 or higher)
$url = mycred_render_affiliate_link( array( ‘url’ => $url ) );

// Append social media share urls
if ( $attr[‘href’] == ‘facebook’ )
$attr[‘href’] = ‘https://www.facebook.com/sharer/sharer.php?u=’ . urlencode( $url );
elseif ( $attr[‘href’] == ‘twitter’ )
$attr[‘href’] = ‘http://twitter.com/home?status=’ . urlencode( $url );
elseif ( $attr[‘href’] == ‘google’ )
$attr[‘href’] = ‘http://plus.google.com/share?url=’ . urlencode( $url );
elseif ( $attr[‘href’] == ‘pinterest’ )
$attr[‘href’] = ‘http://pinterest.com/pin/create/button/?url=’ . urlencode( $url );

// Always make links open in a new window
$attr[‘target’] = ‘_blank’;

// Pass it on
return mycred_render_shortcode_link( $attr, $link_title );
}

but as I can make links are displayed facebook , twitter , etc , so that the user can click

but it seem like it can not be works after added the code snippet into the script file, so may i have your assisting for what i was miss out or anything may be goes wrong?
(see near the bottom sentence that have stated ‘//giore add mycred affiliate code’ which i insert your code snippet)

// custom_share_message_address
$post_essb_post_share_message = $postMetaOptions['essb_post_share_message']; //get_post_meta($post->ID, 'essb_post_share_message', true);
$post_essb_post_share_url = $postMetaOptions['essb_post_share_url']; //get_post_meta($post->ID, 'essb_post_share_url', true);
$post_essb_post_share_image = $postMetaOptions['essb_post_share_image']; //get_post_meta($post->ID, 'essb_post_share_image', true);
$post_essb_post_share_text = $postMetaOptions['essb_post_share_text']; //get_post_meta($post->ID, 'essb_post_share_text', true);
$post_essb_post_fb_url = $postMetaOptions['essb_post_fb_url']; //get_post_meta($post->ID, 'essb_post_fb_url', true);
$post_essb_post_plusone_url = $postMetaOptions['essb_post_plusone_url']; //get_post_meta($post->ID, 'essb_sidebar_pos', true);

if (!$is_shortcode) {
$force_wp_fullurl = isset($options['force_wp_fullurl']) ? $options['force_wp_fullurl'] : 'false';
if ($force_wp_fullurl == 'true') {
//if (ESSBOptionsHelper::exsitQueryString()) {
$url = ESSBOptionsHelper::curPageURL();
//}
}
}


if you want to have a look for the whole script file, i can send it to you.

many thanks
