I am updating post meta with this
update_post_meta( '3100', 'mymetakey', 'mymetavalue' );
How can I add this metakey and metavalue not only to post ID 3100, but several other IDs?
CodePudding user response:
You can define array
of post ids and then you can iterate loop of ids. Try the below code.
$postIds = array( 3100, 1234, 5678....);
foreach ( $postIds as $key => $post_id ) {
update_post_meta( $post_id, 'mymetakey', 'mymetavalue' );
}
Update as per OP comment.
$args = array(
'post_type' => 'product',
'posts_per_page' => -1,
'tax_query' => array(
array(
'taxonomy' => 'product_cat', // custom taxonomy
'field' => 'slug',
'terms' => 'your-category-slug', // taxonomy term (category)
)
)
);
$products = new WP_Query( $args );
if( $products->have_have() ){ while ( $products->have_have() ) { $products->the_post();
update_post_meta( get_the_ID(), 'mymetakey', 'mymetavalue' );
} wp_reset_postdata(); }
