[Plugin: DB Cache Reloaded Fix] Clear cache for a particular query
Your plugin is great for our situation, where a majority of the users will be logged-in and so cannot benefit from page caching.
But now I’m writing my own first plugin. It generates a shortcode for insertion into a page or post. The shortcode may update a database table, and queries involving that table are cached by DB Cache Reloaded Fix.
I have found a hacky way around the problem that works on my local installation:
$time = time();
$wpdb->get_results( $wpdb->prepare( “SELECT $time, my_data FROM ….. ” ..
which changes the query each time it is run.
1. Is there a better way?
2. Is this going to be reliable? I’m more experienced with Oracle than with MySQL, and the MySQL documentation doesn’t make it clear that this syntax is acceptable.
