Slow query while searching a product woocommerce

I was struggling with this issue since long with my wordpress with wooocommerce website. Whenever i was doing a search in admin dashboard for wooommerce products it was taking long time and end up with no results.

SELECT DISTINCT posts.ID as product_id, posts.post_parent as parent_id
    FROM wp_posts posts 
         LEFT JOIN wp_postmeta postmeta ON posts.ID = postmeta.post_id 
    WHERE ( posts.post_title LIKE '%Samsung%' 
            OR posts.post_excerpt LIKE '%Samsung%' 
            OR posts.post_content LIKE '%Samsung%' 
            OR ( postmeta.meta_key = '_sku'
                 AND postmeta.meta_value LIKE '%Samsung%' ) ) 
          AND posts.post_type IN ('product','product_variation') 
    ORDER BY posts.post_parent ASC, posts.post_title ASC

After months of troubleshooting i am still not able to fully resolve the issue, however with this workaround i am finally somewhat relived.

To resolve this issue…

Edit this file – public_html/wp-content/plugins/woocommerce/includes/data-stores/class-wc-product-data-store-cpt.php

In Woocommerce version 3.4.6 look for search_products function

On line no. 1397 look for

$term_group_query .= $wpdb->prepare( ” {$searchand} ( ( posts.post_title LIKE %s) OR ( posts.post_excerpt LIKE %s) OR ( posts.post_content LIKE %s ) OR ( postmeta.meta_key = ‘_sku’ AND postmeta.meta_value LIKE %s ) )”, $like, $like, $like, $like ); // @codingStandardsIgnoreLine.

Remove following code

OR ( postmeta.meta_key = ‘_sku’ AND postmeta.meta_value LIKE %s )

It should then look like this…

$term_group_query .= $wpdb->prepare( ” {$searchand} ( ( posts.post_title LIKE %s) OR ( posts.post_excerpt LIKE %s) OR ( posts.post_content LIKE %s ) )”, $like, $like, $like, $like ); // @codingStandardsIgnoreLine.

Save the file and you should be able to search for products now. The downside with this is you’ll not be able to search SKU’s. But i was ok with this as dont have SKU’s added to my products.

I hope this will help you.

Forgotten wp-admin Password and Username – WordPress




Retrieve WordPress User Name

Go back to PhpMyAdmin, go to the ‘SQL’ tab, and paste this:

SELECT * FROM wp_users LEFT JOIN wp_usermeta ON wp_users.ID = wp_usermeta.user_id WHERE meta_value LIKE '%administrator%'

You should get a list of all the users with the ‘administrator’ role. One of those should be your account. You ought to recognize the email address or something. Then use the password reset function at /wp-login.php to straighten things out. Be sure to check that the email address in the database is an address you still use. If not, change it so that you get the reset email.
