Search…

By default the plugin allows searching any character without restriction. If you however need to replace (or remove) certain special characters, use the code below.
​What is this, and where do I put this custom code?​
1
add_filter('asp_search_phrase_before_cleaning', 'asp_replace_characters', 10, 1);
2
add_filter('asp_query_args', 'asp_replace_characters', 10, 1);
3
​
4
function asp_replace_characters( $s ) {
5
  $characters = "',._-?!"; // Type characters one after another
6
  $replace_with = ' ';     // Replace them with this (space by default)
7
​
8
  if ( is_array($s) ) {
9
    if ( isset($s['s']) && !$s['_ajax_search'] ) 
10
      $s['s'] = str_replace(str_split($characters), $replace_with, $s['s']);      
11
  } else {
12
    $s = str_replace(str_split($characters), $replace_with, $s);
13
  }
14
​
15
  return $s; 
16
}
