where to see the "canonical URLs" function work correctly?

I already choose "use canonical url if speciied" ,while I don't know how to see this function works well
Because I cann't see canonical code in my products page source codes.
So Can you help me on that?

Thank you very much.

Hi,

It is in the head part of the source code, in a link tag.
You should find it thanks to a search on "canonical".

Hi Xavier:
But I never see "canonical" code in my site page's source code.
If I do something wrong?
The only change after use canonical urls is the url of product is unique,regardless of what path I visit this problem,while before the product urls are not stable depends on the visit path.
But I cann't find any "canonical" code in my site's source code.
I think if I cann't see canonical code,the search engines can not see it too.

Hi,

After reading again your first message, I can see that you have selected the option "use canonical url if specified".
Do you have specified it for each products in the product edition page ?

If not, you can potentially select the value "Use canonical URL and generate it if missing", this way you are sure to have canonical urls.

Yes I choose the option "use canonical url if specified".
And I specified it for each product in the product edition page,please see the attached picture
Let's take www.open17.com/fluegas/934-afriso-b20 as an example
In this product detailed page,No cononical code found.

Hi,

Do you had edited the view "product / show" ?
Thanks to check if the following code is present at the top of the view:

<?php
$canonical=false;
if(!empty($this->element->main->product_canonical)){
	$canonical = $this->element->main->product_canonical;
}elseif(!empty($this->element->product_canonical)){
	$canonical = $this->element->product_canonical;
}
if($canonical){
	$doc = JFactory::getDocument();
	$doc->addCustomTag( '<link rel="canonical" href="'.hikashop_cleanURL($canonical).'" />' );
}
?>

Thank you very much Xavier,
I add the codes you provide to product/show,
Is the position right?
Now I can see "cononical" in page source code.
