    session value and radio button

    On one page I have radio buttons below pictures, here is one picture...

    <img src="images/web-aroundworld458c .jpg" width="100" height="51"
    border="0"
    onclick="this.s rc='./images/web-aroundworld458c .jpg';this.heig ht=102;this.wid th=200"
    ondblclick="thi s.src='./images/web-aroundworld458c .jpg';this.heig ht=51;this.widt h=100"
    alt="" /><br />
    <input type="radio" name="image_cho ice" value="lp15-web-aroundworld458c "
    style="width: 35px;"/>LP-15<br />

    ....then I have a link to a page in which if a radio button is chosen, a
    value will be passed to the new page.

    <?php
    $_SESSION['image_choice']=image_choice;
    ?>

    The theory works but what is passed is the wording "image_choi ce" and not
    what I expected...."lp 15-web-aroundworld458c ".

    If the value of image_choice is "lp15-web-aroundworld458c ", then why would
    it return the literal "image_choi ce"?
    How can I get the value of the button to go to the new page?

    Also, does session_start() ; need to be on each php page when passing the
    values between pages?

    Thanks,
    Thad

      Advice: be clearer about what your code is, don't say "I've got this
      and that code", just show us

      Firstly yes session_start needs to be whereever you wish to use the
      session - see http://uk.php.net/session_start
      and secondly
      what is this expected to do?

      <?php
      $_SESSION['image_choice']=image_choice;
      ?>

      don't you mean
      <?php
      $_SESSION['image_choice']=$image_choice;
      ?>

      where $image_choice is what you sent, either $_GET['image_choice'] or
      $_POST['image_choice']
      but you havent actually given enough code to help us help you.

          Re: session value and radio button

          I will try this worded different...

          HTML page 1: I have two radio buttons...
          <?php session_start() ; ?>
          <input type="radio" name="image_cho ice" value="lp13-web-wild165c"
          style="width: 35px;"/>LP-13<br />
          <input type="radio" name="image_cho ice" value="lp14-web-wild289c"
          style="width: 35px;"/>LP-14<br />

          HTML page 2: Problem...on html page 2, how would I show which button was
          pressed?

          Would it be....
          <?php session_start() ;
          echo $_SESSION['image_choice'];
          ?>

          What I am looking to get as a result is lp13-web-wild165c or
          lp14-web-wild289c to be printed to the screen.

              <?php session_start() ;
              echo $_SESSION['image_choice'];
              ?>
              If your form method is POST
              use
              echo $_POST['image_choice'];
              If your form method is GET
              use
              echo $_GET['image_choice'];
              Sessions aren't really relevant to your problem.
