Custom search by attributes only

    I am creating a custom search on front page only for attributes. Can someone direct me in right way? I am still a newbie and I got stuck :/

    Search form is sending url as ?s=&post_type=product&color=blue

    // Woo attributes
$woo_atts = array('color', 'depth', 'length');

// set query vars
function themeslug_query_vars( $qvars ) {
  global $woo_atts;
  foreach($woo_atts as $att)
    $qvars[] = $att;
  return $qvars;
}
add_filter( 'query_vars', 'themeslug_query_vars' , 10, 1 );

// search query vars
add_action('pre_get_posts', 'woo_search_pre_get_posts');

function woo_search_pre_get_posts($query){

  if ( is_search() ) {

    global $woo_atts;

    foreach($woo_atts as $att) :

      if(get_query_var($att)) :

          $meta_query[] = array(
           'key'       => 'pa_'.$att,
           'value'     => get_query_var($att),
           'compare'   => 'LIKE',
           );

     $query->set('meta_query', $meta_query);   

     endif;

     endforeach; 

   }

 }

    Is this even the right approach? Both key and values are correctly set but I don’t get any results

    Uh finally got it working after a few hours…. 

    $query->set( 'tax_query', array(
        'relation' => 'AND',
        array(
          'taxonomy' => $attribute,
          'field' => 'slug',
          'terms' => array(get_query_var($att))
          )
        ) );

    Hey filovewg, thanks for this it helped me on my way to building something similar. Just incase you pop back here, you may find it easier to build your array before setting the query in your pre_get_posts hooked function.

    In your original solution you are also overwriting the set->query each time you iterate through the foreach loop.

    Here is my complete woo_search_pre_get_posts function

    function woo_search_pre_get_posts($query){

  // Good practice to also check we are on the main query to ensure others are not effected
  if ( is_archive() && $query->is_main_query() ) {

    // Build array for tax query
    $tax_array = array();

    foreach($woo_atts as $att) {
      // if the attribute is set, add the tax query to our array
      if(get_query_var($att)) {
        $tax_array[] = array(
          'taxonomy' => 'pa_' . $att,
          'field' => 'slug',
          'terms' => get_query_var($att)
        );
      }
    }

    // Set query only if tax_query array is populated
    if(!empty($tax_array)) {
      // use relation 'OR' or 'AND' depending on output required
      $query->set( 'tax_query', array(
          'relation' => 'AND',
          $tax_array
        )
      );
    }

  }

}

add_action('pre_get_posts', 'woo_search_pre_get_posts');
