How to get connected post IDs by current post ID
To get an array of connected posts you can use the translationIds function. That method is the equivalent of mlp_get_linked_elements in MultilingualPress 2:
The first parameter is the source post id, the second is the column “type” in the wp_mlp_relationships table in the database and the third parameter is the source site id .
About the type value, this must be either “post” or “term”, depending on whether the
Translation of a post or translation of a term is to be queried:
$translations = InpsydeMultilingualPresstranslationIds(1, ‘post’, 1);
it will return an array of key value pairs as site id and post id:
array (size=2)
1 => int 1
2 => int 1
You can loop through $translations like this:
if($translations) {
foreach($translations as $siteId => $postId) {
echo ‘Site ID: ‘ . $siteId . ‘ Post ID: ‘ . $postId . ‘
‘;
}
}
