    Assigning values back to drop down box

    Group,

    I have several drop down boxes that I'd like to repopulate with the value
    the user selected -- after the form posts by calling itself -- these fields
    are blanked out. I am having difficulty getting the drop downs to repopulate
    with the values the user's selected. If any of you have implemented this
    before, how have you done this and what is the syntax?

    Thanks,

      This is pure HTML.

      Option 2 is set:

      <option value="1"></option>
      <option value="2" selected='selec ted'></option>
      <option value="3"></option>

      Regards,
      Matthias

          Here is some sample code that should get you going:

          <?php

          /* this is the form handling code */
          $myselect = '';
          if ( isset( $_POST['myselect'] ) ) { $myselect = $_POST['myselect'] ; }
          if ( isset( $_GET['myselect'] ) ) { $myselect = $_GET['myselect'] ; }

          ?>
          <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

          <html>
          <head>
          <title>Form Select Handler</title>
          </head>

          <body>
          <form action="<?php $_SERVER['PHP_SELF']; ?>" name="myform" id="myform" method="GET">
          <select name="myselect" id="myselect">
          <option value="1" <?php print ($myselect==1) ? 'SELECTED' : ''; ?>>option1</option>
          <option value="2" <?php print ($myselect==2) ? 'SELECTED' : ''; ?>>option2</option>
          </select>
          <input type="submit">
          </form>
          </body>
          </html>

                  This looks very complicated.

                      Use a select box like following:

                      [HTML]
                      <select name="mySelect" >
                      <option value="1" <?=$mySelectOpt ion['1']?>>option1</option>
                      <option value="2" <?=$mySelectOpt ion['2']?>>option2</option>
                      <option value="3" <?=$mySelectOpt ion['3']?>>option3</option>
                      <option value="4" <?=$mySelectOpt ion['4']?>>option4</option>
                      <option value="5" <?=$mySelectOpt ion['5']?>>option5</option>
                      <option value="6" <?=$mySelectOpt ion['6']?>>option6</option>
                      </select>
                      [/HTML]

                      And code your PHP like following:

                      [PHP]
                      $mySelectOption['1'] =
                      $mySelectOption['2'] =
                      $mySelectOption['3'] =
                      $mySelectOption['4'] =
                      $mySelectOption['5'] =
                      $mySelectOption['6'] = '';
                      if(!empty($_REQ UEST['mySelect']))
                      $mySelectOption[$_REQUEST['mySelect']] = 'selected';
                      else
                      $mySelectOption[1] = 'selected'; // Default selected, for first time

                      [/PHP]

                      This is just a possible way to achieve this.
                      Another method will be output your Select box in a loop and check for
                      selected condition, and ouput the *selected* text when necessary.

                      --
                      Cheers,
                      Rahul

                          That's because it is an HTML reply post, which your newsreader apparently
                          does not understand. That is the reason HTML posts on usenet are discouraged.

                              Personally I like to do this:

                              <? $selected = array($menu => "selected") ; ?>
                              <select name="menu">
                              <option value="1" <?=$selected[1]?>>Item 1</option>
                              <option value="2" <?=$selected[2]?>>Item 2</option>
                              <option value="3" <?=$selected[3]?>>Item 3</option>
                              </select>
