Hooks Question

[DJ29Joesph]

I have a hook that I want to add to the admincp login page. I know I have to use adminfunctions.php. The question I have is I have a hook that usually goes in the navbar near the login and submit buttons. Anyway I'm trying to add the hook and I know I have to use

PHP Code:

($hook = vBulletinHook::fetch_hook('hook_name_here')) ? eval($hook) : false; 


But the question I have is how do I add it so it is in php? Do I have to do it in php? Mainly, what am I doing wrong?

Heres what I think it is (yes I know I did change hook_name_here):

PHP Code:

<!-- submit row -->
        <tbody>
        <tr>
            <td colspan="3" align="center"><div style="float: right">
            <?php ($hook = vBulletinHook::fetch_hook('hook_name_here')) ? eval($hook) : false; ?></div>
                <input type="submit" class="button" value="  <?php echo $vbphrase['log_in']; ?>  " accesskey="s" tabindex="3" />
                <?php if ($showoptions) { ?><input type="button" class="button" value=" <?php echo $vbphrase['options']; ?> " accesskey="o" onclick="js_show_options('loginoptions', this)" tabindex="4" /><?php } ?>
            </td>
        </tr>
        </tbody>
        <!-- /submit row -->

The main thing I'm changing (or adding) is:

PHP Code:

<div style="float: right">
            <?php ($hook = vBulletinHook::fetch_hook('hook_name_here')) ? eval($hook) : false; ?></div>

Any help would be great, thanks!
