Hi i am using following snippet for copying the same image url to all translations when create for a specific language from the frontend.

class WpmlFeaturedImageDuplicationFix{
 
    function __construct(){
        // check $sitepress object
        global $sitepress;
        if ( !is_object($sitepress) ) {
            return;
        }
 
        // Add hooks
        add_action( 'icl_make_duplicate', array($this, 'make_duplicate'), 99, 4 );
        add_action('save_post', array($this, 'save_post'), 99, 3);
    }
 
    function make_duplicate($master_post_id, $lang, $post_array, $id){
        $this->copyImageToDuplicates($master_post_id);
    }
 
    function copyImageToDuplicates($post_id){
        global $sitepress;
        $trid = $sitepress->get_element_trid($post_id);
        $translations = $sitepress->get_element_translations($trid);
 
        // get thumbnail and id of src post
        foreach( $translations as $translation ) {
            if ($translation->original=='1') {
                $src_id = $translation->element_id;
                $src_thumbnail_id = get_post_meta($translation->element_id, '_thumbnail_id', true);
            }
        }
 		
        // ensure a src post is found
        if (!$src_thumbnail_id) {
            return;
        } 
 
        // get all duplicates of this post
        $duplicates = $sitepress->get_duplicates($src_id);
 
        // set thumbnail on all duplicates
        foreach( $duplicates as $countryCode => $duplicateId ) {
            update_post_meta ( $duplicateId, '_thumbnail_id', $src_thumbnail_id );
        }
    }
 
    function save_post( $post_id, $post, $update ){
        $this->copyImageToDuplicates($post_id);
    }
}
 
$wpmlFeaturedImageDuplicationFix = new WpmlFeaturedImageDuplicationFix();

all working fine as expected. but i keep having following error showing in the debugging info:

Notice: Undefined variable: src_thumbnail_id in /home3/domain/domain.co/wp-content/toolset-customizations/duplicate-featured-img.php on line 39

I am not sure how to get rid of this error.

Hello,

It is a bug of your custom PHP codes, you can define a default value for variable: src_thumbnail_id, for example, add a line after this line

// get thumbnail and id of src post

like this:

// get thumbnail and id of src post
$src_thumbnail_id = 0;
