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);
}
}
}
}
add_action('save_post', 'auto_generate_month_year_from_date_field', 101);
Problem:
The customer wanted to display only posts with a custom image field in her view. However, when attempting to add a filter for this custom image field, it was not listed, nor were any other custom image fields.
Solution:
After further investigation, it was confirmed that the custom image fields not appearing in the filter section is expected behavior. We suggested using a wpv-conditional shortcode to test if the image exists as a workaround and provided a link to additional code that could help. Rita decided to rework the website to make images a required element when creating profiles.
