vwo

This class provides some simple PHP helper function for implementing Visual Website Optimizer within your website.

Getting Started

You can install this package using Composer by adding this line to your composer.json require statement.

"marcwitteveen/vwo": "dev-master"

And then run from terminal:

sudo composer update

Code Sample

use MarcWitteveen\Vwo\Vwo;

Vwo::asynchronous("xxxxxx", true, $2000, 2500, false);

/* This will render the following code:
<!-- Start VWO Async Smartcode -->
<script type='text/javascript'>
window._vwo_code = window._vwo_code || (function(){
var account_id=xxxxxx,
settings_tolerance=2000,
library_tolerance=2500,
use_existing_jquery=false,
is_spa=1,
hide_element='body',

f=false,d=document,code={use_existing_jquery:function(){return use_existing_jquery;},library_tolerance:function(){return library_tolerance;},finish:function(){if(!f){f=true;var a=d.getElementById('_vis_opt_path_hides');if(a)a.parentNode.removeChild(a);}},finished:function(){return f;},load:function(a){var b=d.createElement('script');b.src=a;b.type='text/javascript';b.innerText;b.onerror=function(){_vwo_code.finish();};d.getElementsByTagName('head')[0].appendChild(b);},init:function(){
window.settings_timer=setTimeout('_vwo_code.finish()',settings_tolerance);var a=d.createElement('style'),b=hide_element?hide_element+'{opacity:0 !important;filter:alpha(opacity=0) !important;background:none !important;}':'',h=d.getElementsByTagName('head')[0];a.setAttribute('id','_vis_opt_path_hides');a.setAttribute('type','text/css');if(a.styleSheet)a.styleSheet.cssText=b;else a.appendChild(d.createTextNode(b));h.appendChild(a);this.load('https://dev.visualwebsiteoptimizer.com/j.php?a='+account_id+'&u='+encodeURIComponent(d.URL)+'&f='+(+is_spa)+'&r='+Math.random());return settings_timer; }};window._vwo_settings_timer = code.init(); return code; }());
</script>
