Predictive Search Location on PHP

[arpittailang]

Hello, I am customizing a wordpress theme. It contains a Location Search that shows locations as drop down menu. But i want to show predictive search such as when user types "NE" it shows "New York, united States". It is also called autocomplete. I want a solution for a it from beginning as i am completely newbie.

 

The Theme has admin panel where an option allow to add locations, and these location are saved in database. I just need these locations to show on predictive search.

Here is the code that calls the location databsae :

 

div class="search_row clearfix">
            <label> <?php _e(SEARCH_LOCATION_TEXT); ?> : </label>   
                <select name="srch_location" id="srch_location" onchange="" class="fl select">
                 <option value=""><?php _e(SEARCH_ALL_LOCATION_TEXT); ?> </option>
                  <?php echo get_location_dl($_REQUEST['srch_location']);?>
                <?php //echo get_category_dropdown_options(get_cat_id_from_name(get_option('ptthemes_locationcategory')),$_REQUEST['srch_location']);?>
               </select>

I think "srch_location" is the location where all these location saved. How can i show these to predictive search. Please answer in steps so i can understand because i dont know php very well.

Also it would be good if yoou include the easy jQuery or AJAX Script that does the job and a guide how to implement in the code.

 

Update: How to call the location where country list is saved using php? for example i am using this code to get the location to be appear on the predictive search :

onchange="<?php echo get_location_dl($_REQUEST['srch_location']);?>"

but its not working but I am 100% sure and tested that this code is working well when i code dropdown for location textbox. I just need to work as well for predictive search.

 

Thank you very much.
