Do stuff on product id

[Nick1973]

I am trying to generate HTML for something in the head section on product information pages only.

So what would be the correct way to write something like this?

if ($current_page_base == 'index' and $cPath == '1' and $products_id == '123') {
  echo 'DO STUFF';
}

I've tried a few different variations, no success though. Thought something like this might work.

if ($current_page_base == 'product_info' and $products_id == '123') {  echo 'DO STUFF';} 

what I am trying to is output an AMP Page URL for product information pages. I can do this on categories by doing this.

if ($current_page_base == 'index' and $cPath == 'YOUR_CATEGORY_ID') {  echo '<link rel="amphtml" type="text/css" href="https://yoururl.com/your-category-name-or-url">';} 

But can't see how I would do similar for a product information page. I need to be able to specify the exact product information page id in a similar way to $cPath == 'YOUR_CATEGORY_ID'

I suspect $products_id is not set at the point you are injecting your code. Try using $_GET['products_id'].

And if your product has attributes, would recommend casting the $_GET['products_id'] to an integer otherwise when clicking on a product link in the shopping cart the "message" will not be displayed.

ok this worked

if ($current_page_base == 'product_info' and $_GET['products_id'] == '123') {  echo '<link rel="amphtml" type="text/css" href="https://MYDOMAINNAME.com/my-url-1.html">';} 
if ($current_page_base == 'product_info' and $_GET['products_id'] == '234') {  echo '<link rel="amphtml" type="text/css" href="https://MYDOMAINNAME.com/my-url-2.html">';} 

You would keep repeating the entries in tpl_main_page.php and where it reads $_GET['products_id'] == '234') - enter your product id.

<link rel="amphtml" type="text/css" href="https://MYDOMAINNAME.com/my-url-2.html">

- would be the link to your AMP page


Thanks for the help guys, if you have anything else to add to this please let me know

To make your page(s) more flexible for relocation, would suggest that the destination links be made more generic so that one doesn't have to update the domain name or the connection method. If the page is located in the root of the catalog then need only to have the href="my-url-2.html" as an example.
If it is at the root of the domain (where the catalog is found in a sub-folder), then thought should be able to use href="/my-url-2.html".

OK yes I get your point and thanks for that. I will look into it. There are some pages that can't go in the root as there are already lightweight HTML landing pages with similar names. But I think the product pages could go there.

Yeah I know all that but I am just not sure if it works the same for AMP pages as they appear to recommend the full URL including the domain name. I suppose the only way to find out though is try it.

Starting in 2016 and continuing through 2018, they say use https://... At least that won't cause the mixed content warning on a site.
