help to write a custom php script to settingup yoast priority to pages or posts

I’m trying to improve this tutorial script including a switch in the first ifcondition to assign a custom priority to my Yoast Xml Sitemap only to certain post or pages.

So i’m trying to say to Yoast which if some pages have certain id the priority have to change, but my script assign the 0.5 value to all pages.

Any help?

add_filter( 'wpseo_xml_sitemap_post_priority', 'my_custom_post_xml_priority', 10, 3 );

function my_custom_post_xml_priority( $return, $type, $post) {

if($type == 'page') {
switch ($post) {
case '8':
case '395':
case '342':
$return = 0.9;
case '5':
$return = 1.00;
case '620':
case '703':
case '603':
case '688':
case '695':
case '614':
case '684':
case '639':
case '628':
case '539':
case '542':
case '521':
case '509':
case '517':
case '528':
case '533':
case '536':
case '548':
case '545':
case '525':
case '551':
$return = 0.7;
break;
default:
$return = 0.5;
break;
}
}

elseif ($type == 'post') {
$return = 0.8;
}

return $return;
}

The solution should is this:

add_filter( 'wpseo_xml_sitemap_post_priority', 'my_custom_post_xml_priority', 10, 3 );

function my_custom_post_xml_priority( $return, $type, $post) {

    if($type == 'page') {
        switch ($post->ID) {
        case '8':
        case '395':
        case '342':
            $return = 0.9;
            break;
        case '5':
            $return = 1.00;
            break;
        case '620':
        case '703':
        case '603':
        case '688':
        case '695':
        case '614':
        case '684':
        case '639':
        case '628':
        case '539':
        case '542':
        case '521':
        case '509':
        case '517':
        case '528':
        case '533':
        case '536':
        case '548':
        case '545':
        case '525':
        case '551':
            $return = 0.7;
            break;
        default:
            $return = 0.5;
            break;
        }
    } elseif ($type == 'post') {
        $return = 0.8;
    }

    return $return;
}

I think that $post is an WP_Post object, then you will have to compare the property ID on the switch.
