Did you activate the snippet after you imported it? Keep in mind, the snippet will have to forever be activated because now the cache and the table will be out of sync until the entry is manually updated on the Connections : Manage Edit admin page.
Are you, by chance, running a caching plugin like WP Super Cache or W3TC? If you are, make sure you flush the page cache.
I’ve tested and retested the snippet. With it activated, I could update line_1
in the wp_connections_address
table directly and it would show correctly on the frontend. If I edited the same entry that I edited directly in the wp_connections_address
table, using the Connections : Manage Edit admin page, both the wp_connections_address
table and the wp_connections
table : addresses
column would be updated accordingly which in turn would show the update correctly on the frontend correctly.
