Introduction The purpose of this document is to explain how to integrate the CarTrawler AJAX booking engine into the web page. To implement the booking engine take the following steps-: Set up the server environment: 1. For the first and most common form, it is required to have a web browser and a PHP enabled web server. You can download PHP installer from http://ie.php.net/downloads.php 2. Ensure curl extension (php_curl.dll) for PHP is enabled and appropriately set the extension_dir directive in php.ini. 3. Download otaproxy, (http://www.cartrawler.com/otaproxy.zip) which contains otaproxy.php. Upload the php file as is to the root directory in the web server. It should not be modified in any way. 4. The otaproxy and the webpage containing the booking engine must be hosted on the same webserver. Set up the webpage with the AJAX Booking Engine: 1. Choosing a DOCTYPE 2. Include certain Javascript include files from the Cartrawler server. 3. Create a HTML table with a placeholder for the booking engine. 4. Using javascript, create a CT_OTA_Engine object. Note: CT_OTA_Engine object should be included in the <body> tag after the placeholder. 5. Customise the booking engine using methods of the CT_OTA_Engine. 6. Invoke the booking engine. Dependencies Browser Support: IE 5.5 or above, FireFox 1.5 or above Javascript must be enabled. For IE, activex controls need to be enabled. Please note: The CarTrawler booking engine is entirely based on AJAX.

Deployments There are three ways the booking engine can be deployed: Easy Client Complete Client Smart Client Easy Client Only Step 1 (where the user is asked to enter their search criteria) is hosted on the website. On clicking Search, the user is redirected to a full-page booking engine showing the results hosted by CarTrawler. This will only require small real estate space on the webpage as in the following example. The recommended minimum width is 300 pixels.

Complete Client The entire booking engine is displayed in one page using the template. This will require a large amount of real estate on your webpage. You must ensure that sufficient space is given to the booking engine so that it can display large availability responses that could be returned in Step 2 of the booking process. The recommended width is 780 pixels. If you intend to embed in iframe, the recommended size of iframe to display the booking engine is 780px width & 700px height (to display 4 cars). Also enable scroll bars in iframe.

More Information Easy Client Include Files Before the <Head> tag include the following DOCTYPE: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/tr/html4/loose.dtd"> or <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> In the <Head> tag include the following javascript files: <script type="text/javascript" src="https://ota.cartrawler.com/cartrawlercustomabe/abe/js/ct_abe.js"></script> HTML Placeholder <div id="abe_abe"><noscript>your BROWSER DOES NOT SUPPORT JAVASCRIPT</noscript></div> Include the <!DOCTYPE> declaration in your document, before the <html> tag as indicated above. Create a HTML table with one row and one column or block element like <div>. Assign the table cell/block element an id="abe_abe". We will use this id later when creating the booking engine object. We have also added a noscript tag, which will display the text YOUR BROWSER DOES NOT SUPPORT JAVASCRIPT in the case where the customer does not have javascript enabled.

Create and customise CT_OTA_Engine for Easy Client <script type="text/javascript">  </script> Explanation: var ctotaengine = new CT_OTA_Engine("ABE"); This creates CT_OTA_Engine object, and ties it to the HTML element identified by abe_abe. ctotaengine.setstep2url("https://www.cartrawler.com/affiliates/afullrequestbook.asp"); This tells the engine the URL of the webpage which will display the result of the availability request.

Linking Easy Client and Complete Client In some scenarios, you would want to host Easy Client on the Step 1 or Search page on your website and on clicking Search, redirected to Complete Client or full-page booking engine hosted by you to display large availability responses. To achieve this, just configure setstep2url in the step1 page to point to complete client hosted by you. ctotaengine.setstep2url("https://yourwebsite/yourcompletebookengine.html"); This tells the engine the URL of the webpage, which will display the result of the availability request. Note: This should be https as this page will take credit card information from the customer. Call Out Method The reserved functions/call out methods can be triggered, if required, on different steps of the AJAX booking engine. The following call out methods is supported in the booking engine: abestep1() function abestep1() // invoked in step1 abestep2() function abestep2() // invoked in step2 abestep3() function abestep3() // invoked in step3 abestep4() function abestep4() // invoked in step4

abestep2_onprogressbar() function abestep2_onprogressbar() // invoked when we search for availability from step1, before the availability is displayed in step2 abestep2_onload() function abestep2_onload() // invoked when we deeplink to step2, before we send the availability request Where to place the script The call out method should be placed proceeding CT_OTA_Engine configuration. That is, include immediately after ctotaengine.displaybookengine(); Example1: Including header (step1/2/3) for the engine This script will display the steps for the engine. function abestep1() { abeid.display("headertype2", "block"); abeid.get("type2header1").classname = "header_style2"; abeid.get("type2header2").classname = "header_style1"; abeid.get("type2header3").classname = "header_style1"; } function abestep2() { abeid.display("headertype2", "block"); abeid.get("type2header1").classname = "header_style1"; abeid.get("type2header2").classname = "header_style2"; abeid.get("type2header3").classname = "header_style1"; } function abestep3() { abeid.display("headertype2", "block"); abeid.get("type2header1").classname = "header_style1"; abeid.get("type2header2").classname = "header_style1"; abeid.get("type2header3").classname = "header_style2"; } function abestep4() { abeid.display("headertype2", "none"); } function abestep2_onload() { abeid.display("headertype2", "none"); } function abestep2_onprogressbar() { abeid.display("headertype2", "none"); }

Example2: Including Google Tracking Pixel The google code snippet to track conversions is placed on the conversion page (in step4 of the AJAX booking engine). Follow the steps below. Include container anywhere on the page <img id="abe_conversiontracking_google" width="1" height="1" border="0" /> Inserting Google Code in the engine: Sample code snippet only - DO NOT USE function abestep4() { var google_conversion_id = 1234567890; var google_conversion_language = "en_gb"; var google_conversion_format = "1"; var google_conversion_color = "666666"; var google_conversion_label = "Purchase"; abeid.get("conversiontracking_google").src="https://www.googleadservices.com/pagead/conversion/ 1234567890/?value=1&label=Purchase&script=0"; } Placing Google Code (conversion.js) to the end of the page <script language="javascript" src="https://www.googleadservices.com/pagead/conversion.js"></script> Support If you require help or support can you direct your queries to our support page at: http://www.cartrawler.com/support/ CarTrawler do not provide telephone or email support for any issues relating to this document.

Miscellaneous configuration ctotaengine.setpopoutiframe (1); This is used for a standalone Step1, based inside an IFrame. The default behaviour is for the results in Step 2 to be displayed inside the same IFrame. When this is set, this will cause the results to popout of the IFrame, taking up the full browser window. ctotaengine.setshowavailnewwindow (1); This is used for a standalone Step1 (both inside an IFrame and outside an IFrame). The default behaviour is for Step2 to be displayed inside the same browser window. When this is set, the engine will attempt to create a new browser window containing the results in Step2. WARNING: Pop up blockers will prevent new browser windows being created by javascript. They will have to be disabled for this functionality to work.
