Fill out event schema from ACF fields

Hello,

Thank you for reaching out to us with your questions about using ACF fields in the event schema and automatically filling in the current URL for an online event.

To pull the starting date of the event from an ACF date/time picker field, you can achieve this by defining a new variable using a filter to get the value from the ACF field and use it in the Schema Generator. Here’s an example of how you can do this:

1. Register the ACF variable in Rank Math by adding code similar to how WooCommerce variables are registered in the Rank Math plugin. You can find an example of registering a WooCommerce variable in the Rank Math plugin here.

2. Use the rank_math/json_ld filter to generate the event schema on the front end instead of adding it manually from the Schema generator. You can add the following code snippet to your theme’s functions.php or rank-math.php file:

add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
    $start_date = get_field('your_acf_start_date_field_name');

    $data['startDate'] = $start_date; // Assign the ACF start date to the startDate field in the JSON-LD data

    return $data;
}, 10, 2 );

Regarding automatically filling in the current URL for an online event, you can achieve this by dynamically populating the Online Event URL field with the current page URL. This can be done using JavaScript or PHP to fetch and insert the current URL into the field.

If you need further assistance or have any more questions, please feel free to ask.

Best regards!

Hello,

Since you are simply using ACF fields for your event information, you can simply use this variable %customfield(FIELD_NAME)% and insert it into the schema fields.

With schema PRO you can fully customize the schema structure to your liking, however, you also need to make sure that it is always valid by checking it here.

As for the Event schema’s startDate, having multiple of that property may cause an invalidation.

Looking forward to helping you.
