我设法通过修改默认的GoogleAnalytics模块来实现它：
app / code / core / Mage / GoogleAnalytics / Block 复制 Ga.php 文件，然后导航至 / www / app / code / local / Mage / GoogleAnalytics / Block 并粘贴（如果不存在则创建必要的文件夹）在 _toHtml（）$ c>中添加新的 Ga.php 中的
code>函数在测试后是否从Magento后端激活分析，测试当前页面是产品详细信息页面：
$ _ product = Mage :: registry（'current_product'）;
if（$ _ product）{
//带有_setCustom的输出代码var
} else {
//输出正常跟踪代码
}
自定义变量集的代码如下所示：
$ this-> addText（'
<！ - BEGIN GOOGLE ANALYTICS CODE - >
< script type = \text / javascript\ >
var _gaq = _gaq || [];
_gaq.push（[\'_setAccount\'，\'UA-25272379-1\']）;
_gaq.push（[\'_setCustomVar\'，1，\'Product View \'，\''。$ _ product-> getSku（）。'\'，3]）;
_gaq.push（[\__trackPageview\']）;
（function（）{
var ga = document.createElement（\'script\'）; ga .type = \'text / javascript\'; ga.async = true;
ga.src =（\'https：\'== document.location.protocol？\'https：/ / ssl\'：\'http：// www \'）+ \'.google-analyti cs.com/ga.js\\';
var s = document.getElementsByTagName（\'script\'）[0]; s.parentNode.insertBefore（ga，s）;
} ）（）;
< / script>
<！ - END GOOGLE ANALYTICS CODE - >
'）;
UPDATE:
Hopefully this is a better explanation of the problem:
I'm trying to pass on the product SKU on my product details page to Google Analytics using _setCustomVar.
I'm running on Magento 1.4.0.1 and my Analytics async code is inserted by the default GA module in the <head> section and it looks like this:
<script type="text/javascript">
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-xxxxxxxx-1']);
_gaq.push(['_trackPageview']);
(function() {
var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();
</script>
The custom variable I'm trying to add has this syntax:
_gaq.push(['_setCustomVar',1,'View Product','<?php echo $_helper->productAttribute($_product, $_product->getSku(), 'sku') ?>',3]);
According to the Analytic documentation, in order for the custom variable to be recorded, the _setCustomVar must be called BEFORE the _trackPageView,
but there's no support for this in the default GoogleAnalytics module. There are 2 issues to this problem:
- How can I add my
_setCustomVar function BEFORE the default tracking code?
- How can I add my
_setCustomVar function ONLY on product pages?
Original post:
I'm trying to store the SKU of the product being viewed by a visitor in a Analytics Custom Variable. The syntax for this is _gaq.push(['_setCustomVar',3,'View Product','SKU12345',2]);.
Obviously this snippet of code should be added only to the product detail pages, and not to the list, cart, or checkout pages. So I've tried editing the view.phtml file in app/design/frontend/default/my_package/template/catalog/product by adding the following piece of code:
<script>
_gaq.push(['_setCustomVar',
1,
'View Product',
'<?php echo $_helper->productAttribute($_product, $_product->getSku(), 'sku') ?>',
3]);
</script>
The problem is that the I'm adding this custom variable AFTER the basic tracking code, which is added by default in the <head> section, so it doesn't get recorded in Analytics.
I tried to avoid altering the core files with the Analytics module in app/code/core/Mage/GoogleAnalytics/Block/Ga.php, but I think the solution may lay there.
How can I add the piece of code that sets the custom variable so that it appears within the basic tracking code BEFORE _gaq.push(['_trackPageview']);?
This is my async code provided by Analytics:
<script type="text/javascript">
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-xxxxxxxx-1']);
_gaq.push(['_trackPageview']);
(function() {
var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();
</script>
Idea from here
Note: I'm using Magento 1.4.0.1 and the Analytics Asynchronous Syntax
I've managed to make it work by modifying the default GoogleAnalytics module:
In app/code/core/Mage/GoogleAnalytics/Block copy the Ga.php file, then navigate to /www/app/code/local/Mage/GoogleAnalytics/Block and paste it (create the necessary folders if they don't exist).
in the new Ga.php, in the _toHtml() function after testing if Analytics is activated from the Magento backend, test if the current page is a product details page:
$_product = Mage::registry('current_product');
if($_product) {
//output code with _setCustom var
} else {
//output normal tracking code
}
The code with the custom variable set looks like this:
$this->addText('
<!-- BEGIN GOOGLE ANALYTICS CODE -->
<script type=\"text/javascript\">
var _gaq = _gaq || [];
_gaq.push([\'_setAccount\', \'UA-25272379-1\']);
_gaq.push([\'_setCustomVar\', 1, \'Product View\',\''.$_product->getSku().'\', 3]);
_gaq.push([\'_trackPageview\']);
(function() {
var ga = document.createElement(\'script\'); ga.type = \'text/javascript\'; ga.async = true;
ga.src = (\'https:\' == document.location.protocol ? \'https://ssl\' : \'http://www\') + \'.google-analytics.com/ga.js\';
var s = document.getElementsByTagName(\'script\')[0]; s.parentNode.insertBefore(ga, s);
})();
</script>
<!-- END GOOGLE ANALYTICS CODE -->
