Is there a way to bulk tag all posts which have for instance "bottle" in their titles? Thanks!

1 Answer 1


Did a little bit of searching around this site and found some links that should help you achieve your goal

1) Search all posts that match a specific title - Found this nifty code on another thread here - A use case example of the above function here

2) Updating the "tags" for a specific post is fairly simple with this function:

  wp_set_object_terms($post_id, 'mytagname', 'post_tag', true);

3) When you put everything together, it should look something like this (this code is untested)

    add_filter( 'posts_search', '__search_by_title_only', 500, 2 );

$query = new WP_Query(
        's'         => 'title_to_search_for'

remove_filter( 'posts_search', '__search_by_title_only', 500 );

if ( $query->have_posts() ) :
    while ( $query->have_posts() ) :
     $post_id = get_the_id();
        wp_set_object_terms($post_id, 'tag_to_add', 'post_tag', true);


Good luck!

  • Hi. Thanks for your detailed reply! The problem is that I have thousand and thousand articles so the website gave me a "504 Gateway Time-out". Is there a way to achieve my goal via SQL command in phpmyadmin ?

  • '504 Gateway Time-Out' means the php script ran longer than the allotted execution time. use 'set_time_limit()' to increase the execution time, and the script will run fine. you should avoid direct query calls to wp db unless you really know what you're doing.
