Problème with duplication of

Resolved

(@46cl)

Il use polylang 1.9.3 and I try to synch custom metasdatas in all languages by using this :

add_filter('pll_copy_post_metas', function ($metas) {
    if (get_post_type() == 'projet') {
        return array_merge($metas, array(
            'galerie'
        ));
    }
});

And I get thoses errors only when I translate a post. Of course no data is synch (not even the thumbnail)

Warning: array_merge(): Argument #1 is not an array in /my-folder/wp-content/themes/bach-nguyen-architecture/config/metaboxes/projet.php on line 69

Warning: array_unique() expects parameter 1 to be array, null given in /my-folder/wp-content/plugins/polylang/modules/sync/admin-sync.php on line 202

Warning: Invalid argument supplied for foreach() in /my-folder/wp-content/plugins/polylang/modules/sync/admin-sync.php on line 205

NB : When I remove the pll_copy_post_metas filter I still have the last 2 errors

Can anybody help me ?

Hi!

Please make a test with Twenty Sixteen + Polylang only. Then switch to your theme and activate other plugins one by one to find out the conflict source.

The problem comes from my theme not from other plugin

I’ve found the solution : I forgot to put return $metas; in another pll_copy_post_metas filter
```
add_filter('pll_copy_post_metas', function ($metas) {
    if (get_post_type() == 'projet') {
        return array_merge($metas, array(
            'galerie'
        ));
    }
    return $metas;
});
```
