I have around 2000 products which has no tags. Now i want to update tag for those products. I want to set post_title=tag for all 2000 products.

Below code works for a product to set CUSTOM TAG to PRODUCT

wp_set_object_terms($productID, array('product_tag1','product_tag2','product_tag3'), 'product_tag');

Instead of complicating the work from front end for each product.

Can someone please guide me how to set post_title=tag using php for all my products.

You can loop through your products and assign the tags, maybe something like this:

Update: If you want to just add a tag to posts which dont have any existing tags, you could do something like this:

<?php
add_action('init', 'add_tags_products');

function add_tags_products()
{
    $args = array(
        'post_type' => 'products', // your product post type
        'posts_per_page' => - 1,
    );

    $posts = get_posts($args);

    foreach ($posts as $post):
        setup_postdata($post);

        // get the title of the post
        $title = get_the_title($post->ID);

        // check to see if the post has any tags
        if( ! has_term( '', 'product_tag', $post->ID ) ) :
            // create the term
            wp_set_object_terms($post->ID, array($title), 'product_tag');
        endif;

        wp_reset_postdata();
    endforeach;

}

Paste the above code in your index.php file for testing and visit the site, and after all the tags are set, remove it. Also backup first in case something happens.
