Combining search results

To produce a combined display of the normal WP search results and the WPPA+ serach results do the following:

Find the file search.php in your theme directory, and bring it in a text editor.
Locate the line where the decision is made if there is anything to show on the page:
<?php if ( have_posts() ) : ?>
and change it into the next 3 lines that will find out if there are posts or photos to be printed:
```
<?php $have_photos = function_exists('wppa_have_photos') && wppa_have_photos('450'); ?>
<?php $have_posts  = have_posts(); ?>
<?php if ( $have_posts || $have_photos ) : ?>
```
The next action is to find the place where the posts are printed. There are two possibilties:
- <?php while ( have_posts() ) { : ?>
  change it into:
  <?php if ( $have_posts ) while ( have_posts() ) { : ?>
- get_template_part( 'loop', 'search' );
  change it into:
  if ( $have_posts ) get_template_part( 'loop', 'search' );
Add after the the closing of the while loop:
if ( $have_photos ) wppa_the_photos();
(make sure this code is within <?php ?> tags)

Notes:

The argument '450' in this call: wppa_have_photos('450'); is the column width you want the albums and photos to be displayed. It is the same as the shortcode argument size="450", and may be ommitted for using the full (responsive) width of the display area.
It is required to have a page assigned to the search results (See Basic settings -> Search -> I -> Item 1: Search landing page) that contains at least a landing page wppa shortcode like [wppa type="landing"] in order to make the links from photos and albums work.
Two working examples for the theme twentyten and twentysixteen (used on theis site) are included in the plugin. See .../wp-content/plugins/wp-photo-album-plus/theme/search-2016.php
