Error with GTM4WP_WPFILTER_COMPILE_DATALAYER

    I am adding custom fields to the data layer through by adding this code to functions.php

    add_filter( GTM4WP_WPFILTER_COMPILE_DATALAYER, “custom_dataLayer”);

    function custom_dataLayer( $dataLayer ) {

    $dataLayer[“price”] = get_field( ‘product_price’, false, false );
    $dataLayer[“name”] = get_field( ‘product_name’, false, false );

    return $dataLayer;
    }

    This worked fine but recently I am getting this error message:

    constant GTM4WP_WPFILTER_COMPILE_DATALAYER – assumed ‘GTM4WP_WPFILTER_COMPILE_DATALAYER’ (this will throw an Error in a future version of PHP) in functions.php on line 62

    Any idea why and how to fix it?

    Hi,

    What changes did you make on your hosting recently?
    Perhaps an upgrade in PHP? WP core upgrade?

    I am hosting on Siteground. PHP 7.3.15 and WP 5.3.2.
    I believe PHP was recently upgraded but otherwise I don’t remember any changes.

    Thanks

    What is you replace the constant to the string value 'gtm4wp_compile_datalayer'?

    This seems to do the trick!

    Thanks!!

    add_filter( ‘gtm4wp_compile_datalayer’, ‘custom_dataLayer’);

    function custom_dataLayer( $dataLayer ) {

    $dataLayer[“price”] = get_field( ‘product_price’, false, false );
    $dataLayer[“name”] = get_field( ‘product_name’, false, false );

    return $dataLayer;
    }
