The current Google Analytics Dashboard for WordPress integrates no Opt-Out to disable tracking, which is required in Europe. Here is a workaround for that.
Paste this into your theme function.php.

if ( !is_user_logged_in() && class_exists('GADWP_Manager') ) { add_action('wp_head', 'ga_optout_script', 1); } function ga_optout_script(){ // Read GA Dashboard Settings $options = (array) json_decode(get_option('gadash_options')); // Get GA Dashboard profiles foreach($options['ga_dash_profile_list'] as $profile){ $ga_ua_profile[$profile[1]] = $profile[2]; } // Get active Analytics profile for the current website $active = $options['ga_dash_tableid_jail']; $activeUA = $ga_ua_profile[$active]; // Add opt-out script + active UA echo "<script> var gaProperty = '".$activeUA."'; var disableStr = 'ga-disable-' + gaProperty; if (document.cookie.indexOf(disableStr + '=true') > -1) { window[disableStr] = true; } function gaOptout() { document.cookie = disableStr + '=true; expires=Thu, 31 Dec 2099 23:59:59 UTC; path=/'; window[disableStr] = true; } </script>"; } |
Then add this to your data privacy document:
|

<a href="javascript:gaOptout()">Disable Google Analytics tracking</a> |
When the defer attribute is present in the script tag, it specifies that the script is executed when the page has finished parsing. A requirement that is enforced by Google for example (Page-Speed ranking).
Currently the WordPress wp_enqueue_script provides no easy way to add new attributes, but there is a way around that :)
The below hack / filter needs to be added to your theme function.php. The filter should be your preferred solution, as the clean_url filter has been deprecated.
Make sure that your website / theme is still loading after adding these changes. If needed you can add more exceptions, as I did for jQuery.

Compressing your content saves bandwidth and improves render time, particular on devices with slow internet connections. Compression allows your web server to provide smaller file sizes that load faster for your visitors. Compression of your HTML and CSS files with gzip typically saves around 50 to 70 % of the file size.

A good candidate is the WP Far Future Expiration Plugin ,which not only activates GZIP compression but adds file expiration for various static file types.

Will be adding some basic information about using the current Facebook API with the PHP SDK. Have been updating a lot of old API integrations over the past 2 months and finally solved many badly documented areas of the new API. Will be updating this in the future, as I dive deeper into the latest API changes.

require_once _DIR_TO_AUTOLOAD.'/facebook_sdk/autoload.php'; use Facebook\FacebookSession; use Facebook\FacebookRedirectLoginHelper; use Facebook\FacebookRequest; use Facebook\FacebookResponse; use Facebook\FacebookSDKException; use Facebook\FacebookRequestException; use Facebook\FacebookAuthorizationException; use Facebook\GraphObject; use Facebook\Entities\AccessToken; use Facebook\HttpClients\FacebookCurlHttpClient; use Facebook\HttpClients\FacebookHttpable; |
Depending on what you want to do with the API, the above needs to be adjusted. Check the Facebook API documentation for more details.

I had a problem with the tag pagination throwing 404 errors and was forced to integrate a custom query into the 404 page, while fixing the rewrite rules ;)
This is how you force a different HTTP response header with WordPress, in this case a simple HTTP/1.1 200 OK.

$GLOBALS['wp_query']->is_404 = false; status_header( 200 ); |

“countUp.js is a dependency-free, lightweight JavaScript “class” that can be used to quickly create animations that display numerical data in a more interesting way.”

var sum = myfoos.reduce(function(a, b) { return a + b; }); var avg = sum / myfoos.length; |

1. Add Vimeo iframe
|
1 |
<iframe id="vimPlayer" width="500" height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe> |
2. Load Froogaloop and add some Javascript
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
var vimID = ""; var playerID = "vimPlayer"; $("#vimPlayer").attr("src", "//player.vimeo.com/video/"+vimID+"?api=1&title=0&byline=0&portrait=0&color=f00010&player_id="+playerID); Froogaloop(jQuery('#'+playerID)[0]).addEvent('ready', ready); function ready(playerID){ Froogaloop(playerID).addEvent('play', play(playerID)); Froogaloop(playerID).addEvent('seek', seek); Froogaloop(playerID).api('play'); } function play(playerID){ alert(playerID + " is playing"); } function seek() { alert('Seeking'); } |
This will add a READY event for the player, which allows you to handle other stuff within that function from that point on. Like making the video responsive using fitVid for example :)
Its important that you reference the playerID in the actual iframe source or the ready function will never fire !
