Custom advanced search

Replies: 0

Hi all,
I created an advanced search form that retrieves custom posts by their meta tags. The search works, except for two issues I cannot manage to solve.
The first is the search page’s template: wordpress lists all post in an archive page (with its template), while I would like to show them in a page that has a template of my choice.
The second issue is related to empty query: if none of the fields is selected, the search page returns me 10 posts chosen by criteria I cannot understand. I’d like it to show me a page with all posts of the given post type. Is it possible?

Thanks for any help.

This is the code for the advanced search form:

<?php

/**
*Registering custom query vars
*
*/

function sy_register_query_var( $vars ){
  $vars[] = 'type';
  $vars[] = 'people';
  $vars[] = 'base';
  $vars[] = 'duration';

  return $vars;
}
add_filter( 'query_vars', 'sy_register_query_var' );

/**
* Build a custom query based on several conditions
* The pre_get_posts action gives developers access to the $query object by reference
* any changes you make to $query are made directly to the original object - no return value is requested
*
*/

function sy_pre_get_posts( $query ){
  if( is_admin() || ! $query->is_main_query() ){
    return;
  }
  $query->set( 'type', get_query_var( 'type' ) );
  $query->set( 'people', get_query_var( 'people' ) );
  $query->set( 'base', get_query_var( 'base' ) );
  $query->set( 'duration', get_query_var( 'duration' ) );

  if( !is_post_type_archive( 'fleet' ) ){
    return;
  }

  $meta_query = array();

  if( !empty( get_query_var( 'type' ) ) ) {
    $meta_query[] = array( 'key' => 'type', 'value' => get_query_var( 'type' ), 'compare' => 'LIKE' );
  } elseif ( !empty( get_query_var( 'people' ) ) ){
    $meta_query[] = array( 'key' => 'people', 'value' => get_query_var( 'people' ), 'compare' => 'LIKE' );
  } elseif ( !empty( get_query_var( 'base' ) ) ){
    $meta_query[] = array( 'key' => 'base', 'value' => get_query_var( 'base' ), 'compare' => 'LIKE' );
  } elseif ( !empty( get_query_var( 'duration' ) ) ){
    $meta_query[] = array( 'key' => 'duration', 'value' => get_query_var( 'duration' ), 'compare' => 'LIKE' );
  }

  if( count( $meta_query ) > 1 ){
    $meta_query['relation'] = 'AND';
  }

  if( count( $meta_query ) > 0 ){
    $query->set( 'meta_query', array($meta_query) );
  }

}
