[Help] I wanna learn Sessions

Hello ,
I wanna learn about session ,
I wanna know how to show a "heelo $user" when user login
and show or hide things depend on the user's access level .
Can anyone tell me where to start, please ?
Thanks..

I choose to assume you are asking how to do this with PHP. If I've guessed wrong, do reply with more information.
I wanna learn about session ,
See Session Handling in the PHP Manual
http://us.php.net/manual/en/book.session.php
I wanna know how to show a "heelo $user" when user login
See echo http://us.php.net/manual/en/function.echo.php
Or print() http://us.php.net/manual/en/function.print.php
and show or hide things depend on the user's access level .
Now you're probably going to require login and database features. DW does have some built-in server behaviors that can help with this, but there is some preparation to do. Here is one of the DW support pages:

Can anyone tell me where to start, please ?

  • Hi! I bought my iPhone from USA and the power button doesn't work. I have warranty. I will come to UK soon. I wanna learn; can i benefit my warranty in UK?

    Hi! I bought my iPhone from USA and the power button doesn't work. I have warranty. I will come to UK soon. I wanna learn; can i benefit my warranty in UK?

    The warranty is not and has never been International.  Warranty and support are only valid in the country of origin.  The only exception is for devices sold in the EU where the EU is treated as one country for warranty and support purposes.

  • I have an iphone 4 but can't update to the new ios coz it has no software update shows in my settings.... Pls help i wanna download new apps.. Thanks

    I have an iphone 4 but can't update ios coz the phone has
    No software update on general setings pls help i wanna download latest apps... Thank u

    Your iOS version is probably too old to support software update.  You must update using iTunes on your computer.
    Make sure your iTunes on the computer is current.  Plug your iPhone into iTunes.  Let it sync.  Then choose "Check for Updates..." from the iPhone's summary tab in iTunes.  That should od it for you.

  • Can someone help me in learning how to make business cards using pages

    can someone please help me in learning how to make business cards using pages

    You could jump start the process with an Avery MS Word 8-up business card template as a free download. Either version of Pages will digest it nicely. Once you load it into Pages, do a File > Save As Template.. , add it to Chooser, and give it your name choice. Both versions of Pages will remove the printer registration marks in all four template corners. The free LibreOffice Writer retains them.

  • Help!! - Live Web Cam Chat in a Captivate E-Learning Session

    I really hope someone can help me with this one.  I am doing an elearning session in Adobe Captivate which needs to contain a live web cam chat.  I was thinking about creating a flash video to record the live web cam chat but have no idea how to do it.  Unfortunately this is one skill that I haven't had the opportunity to learn and have never had to do this before.  Its very new and sophisicated for me!!!!
    Please help someone!!!
    Many thanks
    Lisa

    Hi Lisa
    Okay. Gotcha!
    For starters, you won't want to use Captivate to capture the Web Chat. I recently tried some full motion using Captivate 4 and it's seldom going to give you anything remotely close to what you want. So you will need to investigate some other software to capture the Web Cam stuff.
    Perhaps investigate another Adobe product called Visual Communicator.
    Once you get something that is able to capture the Web Cam, it needs to spit back out a file in FLV or SWF output. You would then drop the FLV into Captivate. (Or present it in a frame on a web page).
    Hopefully this helps a smidge.
    Happy Friday! Rick

  • Help need to learn how to do this?

    1. Name, which has fields:
        - String lastname
        - String firstname
    2. Address, which has fields:
        - int stnum
        - String street
        - String city
        - String postalCode
    3. PassengerRecord, which has fields:
        - int passengerID
        - Name passengerName
        - Address passengerAddr
    4. Passengers, which has fields:
        - int numpassengers
        - PassengerRecord[] passRecords
    5. TrainStation, which has fields:
        - String  trainStationName
        - Address trainStationAddr
        - Passengers passengerRecs
    The main routine, in class MainClass, MUST look like this:
    public static void main(String[] args){
      TrainStation station = new TrainStation();
      station.readIn();
      System.out.printf("station=%s",station.toString());
    }//main
    which creates an instance of class TrainStation,
    then calls the readIn() function of that TrainStation object which will:
    1.  read in the  trainStationName, which is a String
    2.  read in the trainStationAddr, by calling trainStationAddr.readIn()
    3.  read in passengerRecs, by calling passengerRecs.readIn() which
        reads in the number of PassengerRecord objects and
        creates the array passRecords.
        Then, passengerRecs.readIn() calls readIn() on each
        passenger record in array passRecords, which will
        in turn read in the passengerID,
        and call passengerName.readIn(), and passengerAddr.readIn()
    After calling station.readIn(), main will print out all of
    the contents of the TrainStation object pointed to by printing
    station.toString().can someone help me learn this fast like any places where i can read and learn how to do this?

  • Help needed in learning the basics of Java Smart Card and implementation?

    Hello every body,
    I am trying to develop the applications on java contactless smart cards technology.
    Can any body give me the details like how to start?
    What are the required softwares and installation procedure and path settings and etc.?
    I am the beginner in java smart card application development.
    plz help me out

    Dear Friend,
    I would advice to divide learning into two main parts: JavaCard technology and contactless RFID cards. For JavaCard technology you can find useful articles on Sun web-site (developers.sun.com/mobility/javacard/articles/javacard1/). For contactless RFID you can find few useful books at Amazon. Regarding software you need JC development kit. How to install it there is an instrunction in JCDK user guide.
    If it is not a secret what a javacard contactless card you are going to use in your work?
    Yours

  • Wanna learn XSLT mapping??

    hi forum, i want to learn xslt mapping, can the forum pls help me....
    and i want to know in which case XSLT mapping is better than java mapping and Graphical mapping

    Hi Sudeep,
    XSLT  mapping is just a  mapping similar to  Message mapping  available in the SAP XI,  the xml  mapped file  is said to  be XSLT  mapping, A tool  available  from Stylus studio . it  will be  graphical one  and very  easy  one.assume if u want to add zero in front of the
    field we have to add that many zeros  in that field thats it.. similar kind  of lot  of  functions  ready made  available.
    this will make the performance of the system bit  slow.. if  we  use  XSLT mapping  and BPM  then  the interface is in  Task (  will have performance  impact a lot )
    Advantage is  we  can mappe as we  wish  and import the file that it.
