iScript in PeopleSoft

For those who have heard about iScript and wondering what it is, I could give a basic understanding on the

iScripts. iScript is a method by which Peoplesoft offers control to the developer in overriding the people tools

frame work. In simple words using iScript, developer will be able to get complete control on the browser. Youcan create pages which looks like other websites (eg: facebook, amazon etc) still within the Peoplesoft system.

iScript have two main classes, Request and Response. Those who have experience with web development couldeasily relate these words. For others I could explain it in simple words.

Request class will get the parameters passed from the browser. For eg: in google if you search for Peoplesoft,

then the browser will send a request to the server with parameter q and parameter value PeopleSoft. So in ouriScript we can get the parameter value PeopleSoft using the request class and send out appropriate result

(response).

As you have thought, Response class is the class responsible to give result to a query. In the above example

once we receive the search word Peoplesoft and performed the search, we need to display the search result in

the browser. For this we will formulate the result html and prints it on the user browser using the Write() or

WriteLine() method of the response class.

Writing iScript Programs

. You should write iscript programs in record field event of any record starting with WEBLIB_ .

2. The iScript program will be written like a normal function except that the function name starts with IScript_

For example I want to display a hello world page to the users. The basic steps are as follows.

First I choose a record, say WEBLIB_HELLOWORLD and on the record field (say HTML) Field Formula and

write a function IScript_HelloWorld.

Now I create a HTML object with the html code to be printed.

HTML object name is HELLOWORLD.

Hello World

Now my code looks as below.

Function IScript_HelloWorld()

Local string &sHTML;rem Get the text to be printed from the HTML object;

&sHTML = GetHTMLText(HTML.HELLOWORLD);

rem Print the html to the client browser;

%Response.Write(&sHTML);End-Function;

. Now I need to give permission to the iScript. It is like normal activity, go to permission list open web libraries

section and give necessary permission to the iScript (you need to choose iScript by drilling down from theunderlying record).

4. Now you can access your iScript page by going to the below navigationhttp://server:port/psc/site_name/portal_name/node_name/s/WEBLIB_name.FIELDNAME.FieldFormula.IScript_name

If you are already logged in, you will be taken to the hello world page. Otherwise peoplesoft sign in page willappear and from there you will be directly taken to the iscript page on successful login.

Now if you come to real applications, instead of printing hello world, if you want to print a value from data

base. In the place of string Hello world in the HTML definition replace it with %bind(:1).

Now in the code where you get the html text, use the below.

rem I print iscript example as the text;

&sHTML = GetHTMLText(HTML.HELLOWORLD,iscript example);

The hard coded string can be replaced with a variable with has fetched the value from the database. Thus

making your program more interactive. To add on more functionality you could use post functionality in theHTML and obtain the parameters using the Request class and printing sensitive data.

rem Getting parameter passed by the browser.

&sParm = %Request.GetParameter(search);

Now you can do processing based on the obtained string and print the output method.

iScripts are interesting method in peoplesoft to un-cuff the restrictions put by peoplesoft application designer.

You can create content rich pages, implement ajax/json services, create mobile pages, redefine portels that has

visibility in larger crowds, create mobile applications etc using the peoplesoft iscript.

While using iscript, you should take care of the below 3 points

. Browser compatibility of the HTML rendered2. Translation of the text printed on the browser

. Multi-lingual, multi-market and multi-currency situations should be taken care.

You can start with the hello world example and unwind yourself. Im sure it will be fun experience.
