Hi,

I'm trying to add "Query Filter" for a custom field set by the theme that I purchased. The problem is, I don't know how to filter custom field having multiple values (see database under postmeta table and views query filter, screenshot attached).

Custom Field (meta_key):
event_details

Values (meta_value):
• event_date_from: 07/01/2016
• event_date_to: 07/01/2016

I need to filter Upcoming Events and Past Events using event_date_from and event_date_to.

Need your help guys! Thanks in advance.

Hello. Thank you for contacting the Toolset support.

You can not filter view with such field which have multiple values using views filter. For such field I suggest you need to use view's filter hook: 'wpv_filter_query".

When displaying a View listing posts, this filter is applied to the arguments being generated by the View settings before they are passed to the WP_Query class. That means you can add/remove query on fly.

For example:

add_filter( 'wpv_filter_query', 'limit_time_on_query', 99, 3 );
function limit_time_on_query($query_args, $view_setting, $view_id) 
{
 if ($view_id == 999) {
    /// ADJUST your query_arguments with your meta query here as per your custom field as meta key and meta values here
 }
    return $query_args;
}

Where:
Please change "999" with your original view id.

I hope above solution will help you to resolve your issue.

Hi Minesh,

Thank you for your quick response. I'm not a typical back-end developer. Can you give an example of meta_query inside of your sample statement?

Please check following code that may help you:

add_filter( 'wpv_filter_query', 'custom_search_criteria',10,2 );
function custom_search_criteria( $query_args ,$view_settings ) {
 if (isset($view_settings['view_id']) && $view_settings['view_id'] == 14840 ) {
    
             $index = 0;
             if(isset($query_args['meta_query'])){
                $index = count($query_args['meta_query'])+1; 
             }
             $query_args['meta_query'][$index] =   array(
                        'relation' => 'AND', 
                           array(
                                'key' => 'cf-college-cost-instate',
                                'value' => '',
                                'compare' => '!=',
                        ),
                        array(
                                'key' => 'cf-college-employed',
                                'value' => '',
                                'compare' => '!=',
                        ),
                        array(
                                'key' => 'cf-college-finaid',
                                'value' => '',
                                'compare' => '!=',
                        )
        );
     
}
return $query_args;
}

This will requie some PHP and Database knowldege to build such solution that is called custom programming.
