Hi!
It’s not exactly like that. The $allpageposts variable holds an array() of objects, and each object is one result.
Here is a quick snippet I had just written, it takes all the categories from a post and appends it to the end of the post title:
add_filter( 'asp_pagepost_results', 'my_results_modify', 1, 1 );
function my_results_modify( $pageposts ) {
foreach ($pageposts as $k=>$v) {
/** The structure is:
object(stdClass) {
["title"] => "Post title"
["id"] => 1234
["date"] => "2014-08-06 12:48:19"
["content"] => "Post content
["author"] => "author"
["post_type"] => "post"
["image"] => "http://..."
["link"] => "http://..."
}
*/
// Get the post categories
$post_categories = wp_get_post_categories( $pageposts[$k]->id );
$cats = "";
// Concatenate category names to the $cats variable
foreach($post_categories as $c){
$cat = get_category( $c );
$cats = " ".$cat->name;
}
// Modify the post title
$pageposts[$k]->title .= " ".$cats;
}
return $pageposts;
}
I’ve also added the structure in the commented section, so you can see which variables you can access and change.
