In phpMyDirectory version 1.5.0, alpha search has change. The alpha search on the index page and browse categories page searches for categories with the letter selected. On the browse locations page, it searches locations with the letter selected.
In the previous version of phpMyDirectory it searches for listings with the letter selected regardless of which page you are on.
To simplify, in phpMyDirectory version 1.5.0 alpha search which shows something like this
http://www.example.com/sitemap.php?letter=A&id=&type=categories
http://www.example.com/sitemap.php?letter=A&id=&type=locations
while for previous version it show
http://www.example.com/search_results.php?alpha=A
If you are using phpMyDirectory version 1.5.0 but would like the old system, you need to edit a few files,
1. /template/YOURTEMPLATE/browse_categories.tpl
Find
<?php echo $this->block('search_alpha_categories'); ?>
2. /template/YOURTEMPLATE/browse_locations.tpl
Find
<?php echo $this->block('search_alpha_locations'); ?>
3. /template/YOURTEMPLATE/index.tpl
Find both code as in 1 & 2
Replace it with
<?php echo $this->block('search_alpha_listings'); ?>
