X-Cart forums - Add a true Google search to your X-cart.

Hello all,
I've just finished adding a site-specific google-search to our advanced search page. For anyone interested, here's how to do it for x-cart 3.3.1...please note that I've already made fix for the price search bug in version 3.3.1:

First you need to sign up for a Google API key at:
http://www.google.com/apis/

Then, you need to download the excellent google search class and supporting files from the original author (written in French). You can find them here:

ftp://ftp2.xhtml.net/xhtml/php/google.zip

Then extract the files you downloaded and upload everything except index.php into your /customer/ folder.

So you should have copied the following extracted files from the google.zip file to the /customer/ folder:
SOAP_Google.php
PEAR.php
The entire SOAP directory

Then you should replace your customer/search.php page with the following code:

Code:

Then you should replace your /skindirectory/customer/main/search_result.tpl with the following code:

Code:

{ include file="location.tpl" last_location=$lng.lbl_search_results}

{include file="customer/main/navigation.tpl"}

{capture name=dialog}

{include file="customer/main/products.tpl"}

{/capture}

{if $smarty.capture.dialog ne ""} 

        {include file="dialog.tpl" title=$lng.lbl_search_results content=$smarty.capture.dialog extra="width=100%"}

{elseif $google_links ne ""}

        {capture name=dialog2}

                {section name=google_link loop=$google_links}

                {$google_links[google_link]}

                {/section}

                {if $google_nav ne ""}

{/if}

{include file="customer/main/navigation.tpl"}

Oh yeah, and replace the skindirectory/customer/main/advanced_search.tpl with the following code:

{/capture} {include file="dialog.tpl" title=$lng.lbl_advanced_search content=$smarty.capture.adv_search

Now look at the customer/search.php page and fill in your key where it says:

Code:

$clef = 'insert_your_google_key_here';

$site_url = 'www.realestate-school.com';

Replace the parameters with your google key and your url, save and upload the file.

You're done. You now have a google search embedded in your site that will search only your site. It will also offer spelling suggestions whenever possible for misspelled queries that don't return any results. If you wish to change the format of the navigation links at the bottom of the results, just modify the search.php page, as I've not bothered to use $smarty logic for the nav link generation. It's just way easier to do it with php and then spit it out into the template once the links are formatted. Feel free to do whatever you want with this code. Someone else did all the hard work here, I just put it together with x-cart.
