While I was reviewing the docs here, I noticed that the meta queries are done via an SQL query syntax since the WP_Query() won't support meta queries directly. I fully understand that. However, do other parameters such as 'order_by' => 'meta_value' continue to work? If not, what are the workarounds for using meta values in the query to do things like sorting?
Sorry for the late reply. You can still use the parameter 'order_by' => 'meta_value' in WP Query. The SQL query helps you to get a list of post IDs that have the specific field value stored in the custom table.
