how to change the duration in VideoObject Schema to ISO 8601 format

Hello,

Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.

Ideally, the duration should be in ISO 8601 format. If you’ve manually added the Video schema on your page, please update the date with this format: https://rankmath.com/kb/video-schema/#duration

However, you can use the following code snippet to ensure that the duration property in the schema complies with the ISO 8601 standard. Here is the filter code you can use:

add_filter( 'rank_math/snippet/rich_snippet_videoobject_entity', function( $entity ) {
    if ( empty( $entity['duration'] ) ) {
        return $entity;
    }

    $time_parts = explode( ':', $entity['duration'] ); 
    $hours = isset( $time_parts[0] ) ? (int) $time_parts[0] : 0;
    $minutes = isset( $time_parts[1] ) ? (int) $time_parts[1] : 0;
    $seconds = isset( $time_parts[2] ) ? (int) $time_parts[2] : 0;

   
    $entity['duration'] = 'PT' . 
        ( $hours > 0 ? $hours . 'H' : '' ) . 
        ( $minutes > 0 ? $minutes . 'M' : '' ) . 
        ( $seconds > 0 ? $seconds . 'S' : '' );

    return $entity;
} );

Here’s how you can add filters/hooks to your WordPress site:

Hello,

This might happen if the duration is being calculated dynamically based on time differences.

Here’s an updated code snippet that assumes the duration is provided in the correct format (H:M:S or M:S):

add_filter( 'rank_math/snippet/rich_snippet_videoobject_entity', function( $entity ) {
    if ( empty( $entity['duration'] ) ) {
        return $entity;
    }

    $time_parts = explode( ':', $entity['duration'] ); 
    $hours = count( $time_parts ) === 3 ? (int) $time_parts[0] : 0;
    $minutes = count( $time_parts ) >= 2 ? (int) $time_parts[count( $time_parts ) - 2] : 0;
    $seconds = (int) $time_parts[count( $time_parts ) - 1];

    $entity['duration'] = 'PT' . 
        ( $hours > 0 ? $hours . 'H' : '' ) . 
        ( $minutes > 0 ? $minutes . 'M' : '' ) . 
        ( $seconds > 0 ? $seconds . 'S' : '' );

    return $entity;
} );

Thank you.
