Tag: themes

I have written code to use on a single page, but I’ve placed it in the theme’s functions.php and created a javascript file and placed it in the theme’s JS directory.

Recently, the theme was updated and functions.php was overwritten and JS file disappeared.

Where do I need to put this code so when the theme is updated, my code will not be lost?

functions.php:

 add_action('wp_ajax_zip_search', 'zip_search'); add_action('wp_ajax_nopriv_zip_search', 'zip_search' ); function zip_search() {     global $  wpdb;      $  zip = $  _REQUEST["zip_code"];      /**/      $  query = 'SELECT zone FROM Counties WHERE zip = %s';     $  zone = $  wpdb->get_var( $  wpdb->prepare($  query, $  zip) );      $  output = "<h1>".$  zone."</h1>";     $  t_zone = $  zone;     $  trimmed_zone = trim($  t_zone);      $  query = 'SELECT * FROM Managers WHERE zone = %s;';     $  manager_info = $  wpdb->get_row(  $  wpdb->prepare($  query, $  trimmed_zone) );      $  output .= "<table style=\"width:100%\">" .
