I am converting wordpress custom fields into one single array in the wp database. I am able to do it but I have duplicated entries. I just need one. Please guide me. Thanks!
My code:
add_action( 'init', function() {
if ( 'migrate' !== filter_input( INPUT_GET, 'action' ) ) {
return;
}
$query = new WP_Query( [
'posts_per_page' => -1,
'post_type' => 'post',
'post_status' => 'any',
] );
if ( ! $query->have_posts() ) {
return;
}
while ( $query->have_posts() ) {
$query->the_post();
$field_id_1 = 'gallery';
$field_value_1 = get_post_meta( get_the_ID(), $field_id_1, false );
update_post_meta( get_the_ID(), $field_id_1, $field_value_1);
}
} );

@Mulli I got it working this way. Instead of updating the post_meta, I decide to delete the post_meta first and then add_post_meta. Thank you for your help!
