Problem: I have a custom field that holds date-like values in the format YYYY-MM. I would like to add a Query Filter to my View based on this custom field, and set it up so that the results are from the current year and the previous two years.
Solution: Use the wpv_filter_query PHP filter to find date fields "like" the 3 most recent years:
// Filter a View by date-like custom field value YYYY-MM, show only results from current year and two previous years
// https://toolset.com/forums/topic/view-which-filters-on-yyyy-mm/
add_filter( 'wpv_filter_query', 'tssupp_yyyy_mm_two_years_ago', 99, 3 );
function tssupp_yyyy_mm_two_years_ago( $query_args, $views_settings, $view_id) {
$view_ids = array( 123 ); // your view ID or IDs
$date_field_slug = 'field-slug'; // your date field slug
// --------- you should not edit below this line ---------------------
if (in_array($view_id, $view_ids)){
$year = date('Y');
$query_args['meta_query'] = array(
'relation' => 'OR',
'year1_clause' => array(
'key' => 'wpcf-'.$date_field_slug,
'compare' => 'LIKE',
'type' => 'STRING',
'value' => $year
),
'year2_clause' => array(
'key' => 'wpcf-'.$date_field_slug,
'compare' => 'LIKE',
'type' => 'STRING',
'value' => ($year-1)
),
'year3_clause' => array(
'key' => 'wpcf-'.$date_field_slug,
'compare' => 'LIKE',
'type' => 'STRING',
'value' => ($year-2)
)
);
}
return $query_args;
}
Problem:
The user has a select field with dynamic option values. The options of the field are generated using Toolset Types filter wpt_field_options. The generated options are the months of the last two years.
Inside a view, the field is not displayed anymore.
Solution:
It turns out that the values that are not displayed are not included in the values generated by the wpt_field_options filter. Toolset returns an empty value.
The solution is to use a custom shortcode that will return the row value from the database.
// The shortcode needs to be added in Toolset->Settings->Custom Code.
add_shortcode('meta', 'meta_fun');
function meta_fun($atts){
global $post;
$atts = shortcode_atts(array(
'field' => NULL,
), $atts);
extract($atts);
if( NULL === $field ) return;
// return "Voila";
return get_post_meta($post->ID, $field, true);
}
// How to use it inside the view
[meta field="wpcf-production-year-month"]
