[Resolved] Custom Field Filter containing dates are compared to epoch datetime

This thread is resolved. Here is a description of the problem and solution.

Problem:
A View filter uses TODAY() for a date comparison, and it doesn't work because that generates a timestamp and the non-Types date field is stored in the mySQL format.

Solution:
If your custom field must be in a non-timestamp format then the solution is to use the wpv_filter_query hook to modify the query arguments so that they compare the dates in the same format.

Hi,

I'm building an archive view with a custom field filter.

I'm comparing the custom field to 'TODAY', as shown in the attached file.

I always got no results in my view, so I opened the code and noticed the 'TODAY' sql statement used the epoch format ('timestamp').

My question:

Do custom fields containing dates must be formatted with epoch format, rather than standard WordPress ('mysql') format ?

Hi Patrice

Types date fields are stored as UNIX timestamps, hence when you add a date Query Filter it expects to use a timestamp for the comparison, which is what the functions such as TODAY() will generate. (And as timestamps are numbers, the comparison should be NUMBER.)

If you are using a non-Types field where the date is not stored as a timestamp, you should use the wpv_filter_query hook and manually set up the query arguments as required.
