Hello,
First of all i want to underline i'm a complete noob in php.
I need help with this file.
The file comes from a plugin that i'have installed on a wordpress website. The plugin gives a list of stores and maps that are in order of insertion. I need this order to be alphabetical in the "all categories" results and also in the results of each single category.
This is the file
<?php

var $wpdb;
var $table_name;
var $table_name_category;
