Web Page home page:
Searching by category with two characters (ajax request is made when the search field
count reaches 3 characters): (NOTE* I am using ajax request to prevent from page refresh, so
when they user types in a search criteria parameter an ajax request is made to a php script that
builds a query based on the parameter to search the database by category column or title
column.)
(as you can see above, nothing will display when there are less than 3 characters in the search
field)
Searching by category with three characters:
(As you can see 3 books were returned which has CHILDREN as the category)
Searching by title:
(Note the search parameter does not have to be the entire book title, it can be partial book title
or category)
Searching by book title example 2:
Searching by category example 2:
Clearing the search field:
(note clearing the field will remove the previous search results so the user is not confused with
what results belong to what search criteria)
Extracted XML values into database table:
XML Parsing and data extraction Script:
(Note* I have created a pre.php file which is used for auto loading my DB connection and I have
a created a DB.php file which performs the mysql db connection calls)
pre.php file contents:

include "$root/class/$class_name".'.php';
