Why implement your own Social Sharing Button?

Not all but most of social sharing plugins are not optimized for your need
They may load social sharing icons individually which increased unnecessary HTTP requests to your server
If you are using official social sharing buttons then it loads Java Script for each Sharing button which eventually impacts your page load speed significantly
If your page speed is high, your site will rank high in Google Search
If your page speed is high, there are more chances users will return to your site more frequently as it's smooth experience for them

Let's check what all scripts your site loads for above 5 social sharing plugins. If you add more then add an extra script for each.

========> Twitter script : <========

========> Facebook HTML5 script : <=========

var js , fjs = d . getElementsByTagName ( s ) [ 0 ] ;

if ( d . getElementById ( id ) ) return ;

js = d . createElement ( s ) ; js . id = id ;

js . src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.0" ;

fjs . parentNode . insertBefore ( js , fjs ) ;

} ( document , 'script' , 'facebook-jssdk' ) ) ; </script>

========> Buffer script : <========

========> Google+ script : <========

( function ( ) {

var po = document . createElement ( 'script' ) ; po . type = 'text/javascript' ; po . async = true ;

po . src = 'https://apis.google.com/js/platform.js' ;

var s = document . getElementsByTagName ( 'script' ) [ 0 ] ; s . parentNode . insertBefore ( po , s ) ;

} ) ( ) ;

</script>

========> Pinterest script : <========

========> LinkedIn script : <========

There is no point to load above scripts on each and every page on your site.

Now let's get started: Create Social `Sharing` Buttons

Step-1

Go to your theme's function.php file and paste below code. This will add sharing button at the bottom of the post.

function crunchify_social_sharing_buttons ( $content ) {

global $post ;

if ( is_singular ( ) | | is_home ( ) ) {

// Get current page URL

$crunchifyURL = urlencode ( get_permalink ( ) ) ;

// Get current page title

$crunchifyTitle = htmlspecialchars ( urlencode ( html_entity_decode ( get_the_title ( ) , ENT_COMPAT , 'UTF-8' ) ) , ENT_COMPAT , 'UTF-8' ) ;

// $crunchifyTitle = str_replace( ' ', '%20', get_the_title());

// Get Post Thumbnail for pinterest

$crunchifyThumbnail = wp_get_attachment_image_src ( get_post_thumbnail_id ( $post-> ID ) , 'full' ) ;

// Construct sharing URL without using any script

$twitterURL = 'https://twitter.com/intent/tweet?text=' . $crunchifyTitle . '&url=' . $crunchifyURL . '&via=Crunchify' ;

$facebookURL = 'https://www.facebook.com/sharer/sharer.php?u=' . $crunchifyURL ;

$googleURL = 'https://plus.google.com/share?url=' . $crunchifyURL ;

$bufferURL = 'https://bufferapp.com/add?url=' . $crunchifyURL . '&text=' . $crunchifyTitle ;

$linkedInURL = 'https://www.linkedin.com/shareArticle?mini=true&url=' . $crunchifyURL . '&title=' . $crunchifyTitle ;

// Based on popular demand added Pinterest too

$pinterestURL = 'https://pinterest.com/pin/create/button/?url=' . $crunchifyURL . '&media=' . $crunchifyThumbnail [ 0 ] . '&description=' . $crunchifyTitle ;

// Add sharing button at the end of page/page content

$content .= '' ;

$content .= '<div class="crunchify-social">' ;

$content .= '<h5>SHARE ON</h5> <a class="crunchify-link crunchify-twitter" href="' . $twitterURL . '" target="_blank">Twitter</a>' ;

$content .= '<a class="crunchify-link crunchify-facebook" href="' . $facebookURL . '" target="_blank">Facebook</a>' ;

$content .= '<a class="crunchify-link crunchify-googleplus" href="' . $googleURL . '" target="_blank">Google+</a>' ;

$content .= '<a class="crunchify-link crunchify-buffer" href="' . $bufferURL . '" target="_blank">Buffer</a>' ;

$content .= '<a class="crunchify-link crunchify-linkedin" href="' . $linkedInURL . '" target="_blank">LinkedIn</a>' ;

$content .= '<a class="crunchify-link crunchify-pinterest" href="' . $pinterestURL . '" data-pin-custom="true" target="_blank">Pin It</a>' ;

$content .= '</div>' ;

return $content ;

} else {

// if not a post/page then don't include sharing button

return $content ;

}

} ;

add_filter ( 'the_content' , 'crunchify_social_sharing_buttons' ) ;

We have used the_content WordPress hook. It displays the contents of the current post/page.

Here is how your code looks like in functions.php file.

Step-2

Open style.css file of your WordPress theme and put below code for better styling.

.crunchify-link {

padding : 2px 8px 4px 8px !important ;

color : white ;

font-size : 12px ;

border-radius : 2px ;

margin-right : 2px ;

cursor : pointer ;

-moz-background-clip : padding ;

-webkit-background-clip : padding-box ;

box-shadow : inset 0 -3px 0 rgba ( 0,0,0,.2 ) ;

-moz-box-shadow : inset 0 -3px 0 rgba ( 0,0,0,.2 ) ;

-webkit-box-shadow : inset 0 -3px 0 rgba ( 0,0,0,.2 ) ;

margin-top : 2px ;

display : inline-block ;

text-decoration : none ;

}

.crunchify-link:hover,.crunchify-link:active {

color : white ;

}

.crunchify-twitter {

background : #00aced ;

}

.crunchify-twitter:hover,.crunchify-twitter:active {

background : #0084b4 ;

}

.crunchify-facebook {

background : #3B5997 ;

}

.crunchify-facebook:hover,.crunchify-facebook:active {

background : #2d4372 ;

}

.crunchify-googleplus {

background : #D64937 ;

}

.crunchify-googleplus:hover,.crunchify-googleplus:active {

background : #b53525 ;

}

.crunchify-buffer {

background : #444 ;

}

.crunchify-buffer:hover,.crunchify-buffer:active {

background : #222 ;

}

.crunchify-pinterest {

background : #bd081c ;

}

.crunchify-pinterest:hover,.crunchify-pinterest:active {

background : #bd081c ;

}

.crunchify-linkedin {

background : #0074A1 ;

}

.crunchify-linkedin:hover,.crunchify-linkedin:active {

background : #006288 ;

}

.crunchify-social {

margin : 20px 0px 25px 0px ;

-webkit-font-smoothing : antialiased ;

font-size : 12px ;

}

Step-3

Make sure you clear your site cache. I'm using WP Super Cache plugin on my site. If you want to optimize all setting for WP Super Cache then follow the tutorial.

Step-4

Deactivate and Delete other Social Sharing plugin if you have it installed before. That's it.

You should see beautiful sharing buttons on your site. Check out live example at the end of each post on Crunchify.

NOTE: I'm using ShortURL on my blog. If you want to have more social sharing buttons then please visit tutorial.

If you want to show Sharing button at the `top of the post` then use this code (Step-1 only):

function crunchify_social_sharing_buttons ( $ content ) {

global $ post ;

if ( is_singular ( ) | | is_home ( ) ) {

// Get current page URL

$ crunchifyURL = urlencode ( get_permalink ( ) ) ;

// Get current page title

$ crunchifyTitle = htmlspecialchars ( urlencode ( html_entity_decode ( get_the_title ( ) , ENT_COMPAT , 'UTF-8' ) ) , ENT_COMPAT , 'UTF-8' ) ;

// $crunchifyTitle = str_replace( ' ', '%20', get_the_title());

// Get Post Thumbnail for pinterest

$ crunchifyThumbnail = wp_get_attachment_image_src ( get_post_thumbnail_id ( $ post-> ID ) , 'full' ) ;

// Construct sharing URL without using any script

$ twitterURL = 'https://twitter.com/intent/tweet?text=' . $ crunchifyTitle . '&url=' . $ crunchifyURL . '&via=Crunchify' ;

$ facebookURL = 'https://www.facebook.com/sharer/sharer.php?u=' . $ crunchifyURL ;

$ googleURL = 'https://plus.google.com/share?url=' . $ crunchifyURL ;

$ bufferURL = 'https://bufferapp.com/add?url=' . $ crunchifyURL . '&text=' . $ crunchifyTitle ;

$ linkedInURL = 'https://www.linkedin.com/shareArticle?mini=true&url=' . $ crunchifyURL . '&title=' . $ crunchifyTitle ;

// Based on popular demand added Pinterest too

$ pinterestURL = 'https://pinterest.com/pin/create/button/?url=' . $ crunchifyURL . '&media=' . $ crunchifyThumbnail [ 0 ] . '&description=' . $ crunchifyTitle ;

// Add sharing button at the end of page/page content

$ variable .= '' ;

$ variable .= '<div class="crunchify-social">' ;

$ variable .= '<a class="crunchify-link crunchify-twitter" href="' . $ twitterURL . '" target="_blank">Twitter</a>' ;

$ variable .= '<a class="crunchify-link crunchify-facebook" href="' . $ facebookURL . '" target="_blank">Facebook</a>' ;

$ variable .= '<a class="crunchify-link crunchify-googleplus" href="' . $ googleURL . '" target="_blank">Google+</a>' ;

$ variable .= '<a class="crunchify-link crunchify-buffer" href="' . $ bufferURL . '" target="_blank">Buffer</a>' ;

$ variable .= '<a class="crunchify-link crunchify-linkedin" href="' . $ linkedInURL . '" target="_blank">LinkedIn</a>' ;

$ variable .= '<a class="crunchify-link crunchify-pinterest" href="' . $ pinterestURL . '" data-pin-custom="true" target="_blank">Pin It</a>' ;

$ variable .= '</div>' ;

return $ variable . $ content ;

} else {

// if not a post/page then don't include sharing button

return $ variable . $ content ;

}

} ;

add_filter ( 'the_content' , 'crunchify_social_sharing_buttons' ) ;
