Installation

Run this command in your Laravel Nova project:

composer require philperusse/nova-column-filter

Usage

Create a filter with artisan

 $ php artisan nova:filter UserColumnFilter 

Extend your filter class with the ColumnFilter class instead of Nova's base Filter class and add the columns on which you want to filter on in the options

use \philperusse\Filters\ColumnFilter as Filter;

class ColumnFilter extends Filter
{
  
   /**
    * Apply the filter to the given query.
    *
    * @param  \Illuminate\Http\Request  $request
    * @param  \Illuminate\Database\Eloquent\Builder  $query
    * @param  mixed  $value
    * @return \Illuminate\Database\Eloquent\Builder
   */	 
  public function apply( Request $request, $query, $value )
  {
     $args = collect($value)->values()->filter(); //Remove any empty keys.
     if($args->isEmpty())
          return $query;
		  
      return $query->where(...$args->all());
  }
  
  /**
   * Get the filter's available options.
   *
   * @param  \Illuminate\Http\Request  $request
   * @return array
   */
  public function options( Request $request ) : array
    {
        return array_merge(parent::options($request), [
            'columns' => [
                'name'      => 'Name',
                'age'       => 'Age',
            ]
        ]);
    }
}

Customization

You can customize the operator list by overriding the operators key in the filters options.

use philperusse\Filters\ColumnFilter as Filter;

class ColumnFilter extends Filter
{
    public function options( Request $request ) 
    {
        return array_merge(parent::options($request), [
            'columns' => [
                'name'      => 'Name',
                'age'       => 'Age',
            ],
            'operators' => [
                '='     => '=',
                '>'     => '>',
                '>='    => '≥',
                '<'     => '&lt;',
                '<='    => '&le;',
            ]
        ]);
    }

    protected function componentName()
    {
        return 'column-filter';
    }
}

The filter is loosely-based on 64Robots's Date Filter and its custom filter selector component
