Filter view date from month and/or year

Started by: andreaV-4 in: Toolset Professional Support
Quick solution available

Problem:

The customer created a Custom Post Type (CPT) with a date field and wanted to allow users to filter posts by month and/or year using a select list. The Toolset view filters did not support filtering by only month or year because the date field is queried as a timestamp.

Solution:

We explained that it’s not possible to filter by month or year directly using Toolset’s default date field filters. As a workaround, we suggested creating separate custom fields for the month and year, which could then be used in the filter. We provided a code example using the save_post hook to automatically populate these custom fields based on the selected date whenever a post is created or edited:

function auto_generate_month_year_from_date_field($post_id) {
    // Check if it's the correct post type
    if (get_post_type($post_id) == 'YOUR_POST_TYPE') {
          
        // Retrieve the date field
        $date_field = get_post_meta($post_id, 'wpcf-YOUR-CUSTOM-DATE-FIELD-SLUG', true);
  
        if (!empty($date_field)) {
            // Convert the timestamp to a DateTime object
            $date_obj = DateTime::createFromFormat('U', $date_field);
  
            // Check if date creation was successful
            if ($date_obj) {
                // Extract the year and month
                $year = date_format($date_obj, "Y");
                $month = date_format($date_obj, "m");
  
                // Update the custom fields with year and month
                update_post_meta($post_id, 'wpcf-YEAR-FIELD-SLUG', $year);
                update_post_meta($post_id, 'wpcf-MONTH-FIELD-SLUG', $month);
            }
        }
    }
}
