I have some meta fields in WordPress created by theme and i want to update it by using php.
The metafield stores url and i want to add some string after current url in custom meta.
i tried these method Assign/update the custom field value for all posts
and made changes
'post_category' => array(14,16,19);
to select a particular category but it edited all posts of all categories.
and used this method to change meta field but it removed url and changet field.
$dealcode = "&deal_code=coupon"; $urlvalue = get_post_meta( $post->ID, 'metakey', false); $urlvalue = $urlvalue . $dealcode; update_post_meta( $post->ID, 'metakey', $urlvalue );
please can anyone fix this. Thanks.
