    problems

    Hi guys,
    On my site, the members can upload photos to a selected gallery, the photos
    will go into the correct folder depending what gallery they click.

    This all works ok, accept wen it causes an error, like the file exists or
    not enough data has been entered. It is then redirected to the addphotos
    page, but this time it loses which folder it should go into.

    addphotos2.php

    $table=$_GET[gal];
    $folder=$_GET[folder];
    echo $error; ?>
    <form action="connect photos.php" method="post"
    enctype="multip art/form-data">
    File:<br>
    <input type="file" name="imagefile " size="30"><br>
    Title:<br>
    <input type="text" name="title" size="50" maxlength="100" ><br>
    Comment:<br>
    <input type="text" name="comment" size="50" maxlength="200" ><br>
    <input type="hidden" name="table" value="<?php echo $table ?>">
    <input type="hidden" name="folder" value="<?php echo $folder ?>">
    <p>
    <input type="submit" value="Add Photo To <?php echo $folder?>"
    name="submit"> Please click only once, this may take a while.
    </form>

    connectphotos.p hp

    if
    (file_exists("/usr/local/psa/home/vhosts/x-tractband.co.uk/httpdocs/x-tract/
    photos/".$folder."/".$_FILES['imagefile']['name']))
    {
    $error= "<font face=\"Arial\" color=\"Yellow\ "><strong>F ile with name
    (".$_FILES["imagefile"]["name"] .") already exists</strong></font><br> ";

    include 'addphoto2.php' ;
    }

    how do i get the data sent by the form in the 1st place, to see be available
    when the error occurs.

    Hope fully you understand what i mean.

    Thanks

      Re: problems

      That's because you use the GET variable 'folder' to set the selected
      folder in your addphotos2.php script:

      $folder=$_GET[folder];

      and

      <input type="hidden" name="folder" value="<?php echo $folder ?>">

      The connectphotos.p hp doesn't send a querystring to the addphotos2.php
      script, hence $_GET[folder] will be null.

      To store the value of $_GET[folder] you could use a session-var for
      instance, so it'll still be available after an error occured.

      HTH.

              Use session_start in each script you want to use your session
              variables:

              addphotos2.php
              <?php
              session_start() ;
              // check if $_GET['folder'] is set, if not use the session-var
              //
              if (isset($_GET['folder'])
              {
              $folder = $_GET['folder'];
              $_SESSION['folder'] = $folder;
              }
              else
              {
              $folder = $_SESSION['folder'];
              }

              .... other code ....
              ?>

              in connectphotos.p hp you should destroy the session when you don't need
              it anymore. That's probably when you don't have an error, so you get:

              <?php
              session_start() ;

              if
              (file_exists("/usr/local/psa/home/vhosts/x-tractband.co.uk/httpdocs/x-tract/photos/".$folder."/".$_FILES['imagefile']['name']))
              {
              $error= "<font face=\"Arial\" color=\"Yellow\ "><strong>F ile with
              name
              (".$_FILES["imagefile"]["name"] .") already exists</strong></font><br>
              ";

              include 'addphoto2.php' ;
              }
              else
              {
              session_destroy ();
              }
              ?>

              Also make sure to read the PHP manual page on sessions:
              PHP: session_start - Manual
              http://nl3.php.net/session_start
              Start new or resume existing session

                      Re: problems

                      I think that's because of the
                      include 'addphotos2.php '

                      That way session_start gets called twice, first in connectphotos.p hp
                      and then in addphotos2.php.

                      You can circumvent that by moving the session_start() in
                      connectphotos.p hp to the else block.

                      Probably a cleaner way is to circumvent the include 'addphotos2.php ',
                      by using:

                      header("Locatio n: addphotos2.php" );

                      Make sure you don't output *anything* before using the header call
                      though.

                          if (!isset($_SESSI ON)) session_start() ;
