I'd like to do a search and replace of post titles but only affect those with a specific tag.

Eg,

Change post title: This is a new post

to: This is an old post

but on only on posts that have the tag: old

  • I looked at some search and replace plugins but couldn't find one where the option was just to change posts with a specific tag. – Austin Apr 20 '15 at 13:25

//Search by tags
$query = new WP_Query( 'tag=old' );

// Then update post titles 
if ( $query->have_posts() ) {
    while ( $query->have_posts() ) {
        $query->the_post();
        //check if title have "a new"
        if(strpos(get_the_title(),'a new') !== false) :

            $post = array(
                'ID'=> get_the_id(),
                'post_title'=> str_replace('a new','an old',get_the_title())
            );

            // Update the post into the database
            wp_update_post( $post );

        endif;
    }
}
  • Wouldn't this update all posts with tag=old to the new post title? I only want to update those that have matching title 'This is a new post'. More specifically I only want to change that part of the title. Search and replace 'a new' to 'an old'. – Austin Apr 20 '15 at 11:23
  • @Austin i have updated code according to your requirements – M Haseeb Apr 20 '15 at 11:59
  • @M Thanks for the updated code. I'm assuming this will change the whole title to "This is an old post"? I only want to change the part 'a new' and replace it with 'an old'. The title I have given is just an example - I have 100's of posts with different titles but common words that I have to replace. – Austin Apr 20 '15 at 13:36
  • @Austin i replaced it again :) – M Haseeb Apr 20 '15 at 17:56
