Add echo to my wordpress sidebar for non-connected users

问题

i have Nice Login Widget which does not have any link to the registration page for non-members (simple visitors). I would like to visualize the Inscription link on the sidebar, just under the login widget but NOT anymore when someone is logged in !

The idea is that i will visualize the link with echo and by its css i could position it absolute.

I do not know anything about php, i tried to add some codes in my sidebar.php file but it does not work :

The sidebar.php is a classic twentyeleven theme :

<?php

if ( 'content' != $current_layout ) :
?>
        <div id="secondary" class="widget-area" role="complementary">
            <?php if ( ! dynamic_sidebar( 'sidebar-1' ) ) : ?>

                <?php
                    if ( is_user_logged_in() ) {
                        echo '';
                    else
                        echo '<a class="inscrip-link" href="http://www.igorlaszlo.com/test/register/">Inscription</a>';
                ?>

                <aside id="archives" class="widget">
                    <h3 class="widget-title"><?php _e( 'Archives', 'vihegay' ); ?></h3>
                    <ul>
                        <?php wp_get_archives( array( 'type' => 'monthly' ) ); ?>
                    </ul>
                </aside>

                <aside id="meta" class="widget">
                    <h3 class="widget-title"><?php _e( 'Meta', 'vihegay' ); ?></h3>
                    <ul>
                        <?php wp_register(); ?>
                        <li><?php wp_loginout(); ?></li>
                        <?php wp_meta(); ?>
                    </ul>
                </aside>

            <?php endif; // end sidebar widget area ?>
        </div><!-- #secondary .widget-area -->
<?php endif; ?>

My added codes in above codes are :

<?php
    if ( is_user_logged_in() ) {
        echo '';
    else
        echo '<a class="inscrip-link" href="http://www.igorlaszlo.com/test/register/">Inscription</a>';
?>

Then i would add the css to the link class inscrip-link :

.inscrip-link {
position:absolute;
top:300px;
left: 30%;
z-index:1;
}

Can someone tell me how to do this ? (I accept better solution as well !:))

回答1:

Your code seems to be missing a few curly brackets.

<?php
    if ( !is_user_logged_in() ) 
    {
        echo '<a class="inscrip-link" href="http://www.igorlaszlo.com/test/register/">Inscription</a>';
    }
?>

I have changed your code a bit. The register link will only show when a user is not logged in.

Finally i found a better solution for my case to be able to add my link with relative position to the sidebar... if someone has the same problem :

I added a text widget with my inscription link (#text-7) under my login widget.
In sidebar.php I added a widget with the same id (#text-7) which gives a classe to the body when users are logged-in (see php codes below).
In the style.css i give style to the #text-7 widget and i display:none when the body class is "logged-in" (see codes below).

PHP

        <aside <?php echo (is_user_logged_in() ? 'class="widget widget_text logged-in"' : ''); ?> id="text-7" class="widget">
            <h3 class="widget-title"></h3>
            <div class="center"><a href="http://www.igorlaszlo.com/test/register/">Inscription</a></div>
        </aside>

CSS

#text-7 {position:relative;margin: -50px auto 30px;z-index:1;}
.logged-in #text-7 {display: none;}

Together with my personal class, i also added all other classes to the widget what a widget should have (widget and widget_text) because if not, it did not work for me... maybe it is just a "handmade" code but it work fine !
