    hi to the community,

    i'm building a widget to login from the sidebar and print errors if any,
    so everything is working fine except that when i login it returns an error:
    Warning: Cannot modify header information - headers already sent.....

    the code of the widget:

    <?php
    // Custom Login/Meta Widget
    function widget_artdev_meta() { ?>
    
    <?php global $user_ID, $user_identity, $user_level ?>
    <?php if ( $user_ID ) : ?>
    <div class="widget">
    	<h2>Control Panel</h2>
    	<ul>
    		<li>Identified as <strong><?php echo $user_identity ?></strong>.
    		<ul>
    			<?php if ( $user_level >= 10 ) : ?>
    			<li><a href="<?php bloginfo('url') ?>/wp-admin">Dashboard</a></li>
    			<?php endif // $user_level >= 10 ?>
    
    			<?php if ( $user_level >= 1 ) : ?>
    			<li><a href="<?php bloginfo('url') ?>/wp-admin/post-new.php">Write an article</a></li>
    			<?php endif // $user_level >= 1 ?>
    
    			<li><a href="<?php bloginfo('url') ?>/profile">Profile & personal options</a></li>
    			<li><a href="<?php echo wp_logout_url( $_SERVER['REQUEST_URI'] ); ?>" title="Exit">Exit</a></li>
    		</ul>
    		</li>
    	</ul>
    </div>
    
    <?php elseif ( get_option('users_can_register') ) : ?>
    
    <?php
    if ( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) && $_POST['action'] == 'log-in' ) :
    	global $error;
    	$login = wp_login( $_POST['log'], $_POST['pwd'] );
    	$login = wp_signon( array( 'user_login' => $_POST['log'], 'user_password' => $_POST['pwd'], 'remember' => $_POST['rememberme'] ), false );
    endif;
    ?>
    
    <div class="widget">
    	<h2>Identification</h2>
    
    	<?php if ( $error ) : ?>
    		<p class="error">
    			<?php echo $error; ?>
    		</p><!-- .error -->
    	<?php endif; ?>
    
    	<ul>
    		<li>
    		<form action="<?php the_permalink(); ?>" method="post">
    			<label for="log">User ID
    				<input type="text" name="log" id="log" value="<?php echo wp_specialchars(stripslashes($user_login), 1) ?>" size="22" class="input_text_login alignright" />
    			</label>
    			<label for="pwd">Password
    				<input type="password" name="pwd" id="pwd" size="22" class="input_text_login alignright" />
    			</label>
    				<input type="submit" name="submit" value="Login" class="button" style="margin-right:35px; width:70px;" />
    				<input name="rememberme" id="rememberme" type="checkbox" checked="checked" value="forever" /> Remember me
    				<input type="hidden" name="action" value="log-in" />
    				<input type="hidden" name="redirect_to" value="<?php echo $_SERVER['REQUEST_URI']; ?>"/>
    		</form>
    		</li>
    		<li><a href="<?php bloginfo('url') ?>/wp-login.php?action=lostpassword">Recover password</a></li>
    		<li><a href="<?php bloginfo('url') ?>/register">Register</a></li>
    	</ul>
    </div>
    
    <?php endif // get_option('users_can_register') ?>
    <?php }
    if ( function_exists('register_sidebar_widget') )
    register_sidebar_widget(__('→ Login/Meta Widget','artdev'), 'widget_artdev_meta');
    ?>

    thanks a lot!
    Philip
