do have form wrapped in form tag? should wrapping html code there tag. otherwise there no form submit , thing in $_get array update.
session_start() going initialize session, nothing in code see adds txtquant session. if doing is, clicks "update" link , submits update code snippet have won't work. need wrap table on bottom there in form:
<?php if(!empty($_session["products"])){ ?> <form> <?php ($i=0; $i< count($_session["products"]); $i++) { ?> <tr> <td><?php echo($_session["products"][$i]); ?></td> <td width="10px"> </td> <td><input type="text" name="txtquant[]"></td> <td width="10px"> </td> <td><?php echo($_session["amounts"][$i]); ?></td> <td width="10px"> </td> <td><input type="submit" value="update"></td> <td><input type="hidden" name="update" value="<?php echo($i); ?>" /></td> </tr> <?php } ?> </form> <?php } ?>
