[Addon] AdWords Dynamic Remarketing Tag

[fur]

This a light-weight add-on for Google AdWords dynamic remarketing tag.

 

Dynamic remarketing lets you reach your past site visitors with ads that show the specific products people viewed on your site. Once you've set up your dynamic remarketing campaign, you'll need to add the dynamic remarketing tag, including custom parameters, to your site so your lists can start working.

hi Richard, thank you for your contribution.

I've just a little problem: I've installed SPPC on my web page and when I made a special offer the tag doesn't charge the special price but only the original price.

 

I think that it should be very important for the remarketing campaign that the special would be shown.

 

do you have any idea?

thank you again for your help.

Hi Richard,

I thought I've solved the problem doing this change in FILENAME_PRODUCT_INFO, but it seems doesn't work correctly.

 

case FILENAME_PRODUCT_INFO:

global $_GET;

if(tep_not_null($_GET['products_id'])){

$return[0] = "'" . $_GET['products_id'] . "'";

global $product_info;

if ($new_price = tep_get_products_special_price($product_info['products_id'])) {

$product_info['specials_new_products_price'] = $new_price;

}

$return[2] = $product_info['specials_new_products_price'] ? $product_info['specials_new_products_price'] : $product_info['products_price'];

}

$return[1] = 'product';

break;

 

do you other ideas... ? I'm not a professional coder.... :-

 

thank you

Thanks for pointing this out riccardo,

 

My apologize I customized products_info.php page and put $product_info['specials_new_products_price'] by my own.

 

Your approach is correct and I cannot see anything wrong in your code...

 

My site doesnt have SPPC installed so I can't test it esaily... My updated version work good in special price with function tep_get_products_special_price()...

 

So... may be if you can locate and post the part of code where the special price is shown in product_info.php, that may help debugging...

Hi richard,

I've tested your updated version and it works great as it is, even with SPPC installed.

Great job!

thank you very much!

good, my bad didnt test well before releasing it~

[rikic]

Hi richard,

I've tested last version of yo our contribution on my website abnd I think there's a bug: it doesn't charge the "coma" in the price.

I mean, if the price is € 109,00 it shows 10900.

any idea?

thank you very much

riccardo

[fur]

thx for your reply, rikic

 

I did that on purpose, in US dollars e.g. $1,234.56 need to be 1234.56...

had no idea comma in € can be decimal point too... may work on it these few days...

[fur]

v.1.4.2 uploaded, please try and test. :D

[rikic]

Hi Richard, I'va just tested your last version: everything is working.

Great! thank you again!

Hi stubbsy,

 

sorry for the very late reply. It seems work ok in your product page. Have you fixed it?

[Roaddoctor]

echo 'ecomm_totalvalue: \'' . $this->page_totalvalue . '\'' . "\n";

This line is giving me issues...

First the current Google spec call for a numeric entry with no quotes.

 

I tried changing to

echo 'ecomm_totalvalue: ' . $this->page_totalvalue . '' . "\n";

which works on product pages that have a price, but gives an error on all other pages that do not have a product (null entries), with error "Tag Paramater object could not be parsed."

 

So the original line works ok on non product pages but not well on product pages.

The revised line works ok on product pages, but not on other pages

 

What do do? Any help appreciated.  The code is brief, so here is the whole file: adwords_tag.php (remarketing tag)

easiest I think is to initialize the value to 0 in the 'var' declaration in the beginning of the file.

 

	var $page_totalvalue = 0;

it is kinda dirty, possibly you should not have that line when you have null values, but forcing it to be 0 will likely get rid of the error for you.

[♥kymation]

@@Roaddoctor You can just test the value and change the output to suit:

  if( empty( $this->page_totalvalue ) {
    echo 'ecomm_totalvalue: \'\'' . "\n"; // No use including the variable if it's empty (null)
  } else {
    echo 'ecomm_totalvalue: ' . $this->page_totalvalue . "\n";
  }

Sorry to say, but my addition of the initialization of the variable to 0 logically does the same and I think is much cleaner code.

[Rachael w.]

I've tried the fixes mentioned here and I still can't get rid of the error: Number field should not be quoted: 'ecomm_totalvalue'

When I try either of the fixes the page shows no tags. With the original code it's just the error. 

Anyone still working on this?

I see Google tag changed

Global tag in header:

<!-- Global site tag (gtag.js) - Google Ads: your tag number -->
<script async src="https://www.googletagmanager.com/gtag/js?id=AW-your tag number"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'AW-your tag number');
</script>

 

and also to add recommended event snippet:

<script>
  gtag('event', 'page_view', {
    'send_to': 'AW-your tag number',
    'value': 'replace with value',
    'items': [{
      'id': 'replace with value',
      'google_business_vertical': 'retail'
    }]
  });
</script>

 

Anyone done an update on this?
