    open functions.php and add this to the top:

    <?php
    if ( function_exists('register_sidebars') )
    register_sidebars(6, array(
    'before_widget' => '<div id="%1$s" class="widget %2$s">',
    'after_widget' => '</div>',
    'before_title' => '<h2>',
    'after_title' => '</h2>

      where 6 is the number of your widgetized sidebars,
      save it.

      open sidebar.php (or left sidebar/right sidebar) and add this to the top after div sidebar id/class:

      <?php if ( function_exists('dynamic_sidebar') && dynamic_sidebar(6) ) : else : ?>

      where 6 is the sixth sidebar you want to register.

    Adding most popular post without a plugin to a WordPress theme:

    <?php

    save it, open single php template, add this to an appropriate place:

    <?php breadcrumb(); ?>

    you might want to add more info like this:

    <?php previous_post_link(); ?> | <?php breadcrumb(); ?> | < a accesskey="s" title = "Sitemap will help you find your interests at this site." href = "/sitemap/">Sitemap</ a > | <?php next_post_link(); ?> | < a accesskey="t" href = "#top" title= "Jump to Page Top">Top ↑</ a >

    Add exec php to your WordPress theme, exec is the ability to post php and js codes in your posts and pages, e.g. archive plugins:

    open functions php file, add this:

    <?php
    define('EXECPHP_VERSION', '2.0');
    define('EXECPHP_CAP', 'exec_php');
    function execphp_fix_tag($match)
    {
    // replacing WPs strange PHP tag handling with a functioning tag pair
    $output = '<?php'. $match[2]. '?>';
    return $output;
    }
    function execphp_eval_php($content)
    {
    // for debugging also group unimportant components with ()
    // to check them with a print_r($matches)
    $pattern = '/'.
    '(?:(?:<)|(\[))[\s]*\?php'. // the opening of the <?php or [?php tag
    '(((([\'\"])([^\\\5]|\\.)*?\5)|(.*?))*)'. // ignore content of PHP quoted strings
    '\?(?(1)\]|>)'. // the closing ? > or ?] tag
    '/is';
    $content = preg_replace_callback($pattern, 'execphp_fix_tag', $content);
    // to be compatible with older PHP4 installations
    // don't use fancy ob_XXX shortcut functions
    ob_start();
    eval(" ?> $content <?php ");
    $output = ob_get_contents();
    ob_end_clean();
    return $output;
    }
    function execphp_restricted_eval_php($content)
    {
    global $post;
    if (!isset($post) || !isset($post->post_author))
    return $content;
    $poster = new WP_User($post->post_author);
    if (!$poster->has_cap(EXECPHP_CAP))
    return $content;
    return execphp_eval_php($content);
    }
    function execphp_install_cap()
    {
    global $wp_roles;

    // if there is at least one role with the EXECPHP_CAP capability, then
    // the plugin was previously been installed and we must not do
    // anything; don't rely that the cap is attachted to the same roles
    // as during installation because this could already be changed
    // by the administrator

    foreach($wp_roles->role_objects as $role)
    {
    if ($role->has_cap(EXECPHP_CAP))
    return;
    }

    $role = get_role('administrator');
    if ($role !== NULL)
    $role->add_cap(EXECPHP_CAP);
    $role = get_role('editor');
    if ($role !== NULL)
    $role->add_cap(EXECPHP_CAP);
    }

    function execphp_activate_1_x()
    {
    add_filter('the_content', 'execphp_eval_php', 1);
    }

    function execphp_activate()
    {
    add_action('admin_menu', 'execphp_install_cap');
    add_filter('the_content', 'execphp_restricted_eval_php', 1);
    }

    function execphp_init()
    {
    global $wp_version;
    if (substr($wp_version, 0, 2) == "1.")
    execphp_activate_1_x();
    else
    execphp_activate();
    }
    add_filter('init', 'execphp_init');
    ?>

    save it, from now all php and/or js java codes will be executed throughout WordPress posts and pages.

    Separating Trackbacks from Comments

    Open comments.php, and search for the following line:

    <?php foreach ($comments as $comment) : ?>

    paste the following after the above line:

    <?php $comment_type = get_comment_type(); ?>
    <?php if($comment_type == 'comment') { ?>

    find this line:

    <?php endforeach; /* end for each comment */ ?>

    paste this one line BEFORE it:

    <?php } else { $trackback = true; } /* End of is_comment statement */ ?>

    now find this line:

    <?php else : // this is displayed if there are no comments so far ?>

    and paste this BEFORE it:

    <?php if ($trackback == true) { ?>
    <h3>Trackbacks</h3>
    <ol >
    <?php foreach ($comments as $comment) : ?>
    <?php $comment_type = get_comment_type(); ?>
    <?php if($comment_type != 'comment') { ?>
    < li ><?php comment_author_link() ?></ li >
    <?php } ?>

    save it.
    <?php endforeach; ?>

    WordPress Conditional tags:

    is_home()
    used on the main blog page, usually your home page

    is_single()
    used on single blog post pages

    Sidebar examples

    <?php /* If this is the frontpage */ if ( is_home() || is_page() ) { ?>
    <?php wp_list_bookmarks(); ?>

    < li><h2>Meta</h2>
    < ul>
    <?php wp_register(); ?>

    < li><?php wp_loginout(); ?></ li>
    < li>< a href ="//validator.w3.org/check/referer"" title=""This">Valid <abbr title="eXtensible HyperText Markup Language">XHTML</abbr>< /a></ li>
    <li >< a href= "//gmpg.org/xfn/""><abbr title="XHTML Friends Network">XFN</abbr>< /a>< /li>

    <li >< a href ="//wordpress.org/"" title=""Powered">WordPress< /a></ li>

    <?php wp_meta(); ?>
    < /li>
    < /ul>
    < /li>
    <?php } ?>

    display your blogroll and meta items on the sidebar of the homepage and single pages only - not on any archive pages, author pages, 404 pages

    NOTE: enabling widgets within this area is slightly tricky, as each conditional element
    will carry its own widget area e.g. sidebar 1, sidebar 2...

    setBodyId function

    add this to the functions php, of course your else if paths has to reflect your own server/wp settings:

    <?php function setBodyId() { $path = $_SERVER['REQUEST_URI']; if(!isset($bodyId)) { if(eregi(’^/about/’,$path) == 1) { $bodyId = ‘about’; } else if(eregi(’^/blog/’,$path) == 1) { $bodyId = ‘blog’; } else if(eregi(’^/contact/’,$path) == 1) { $bodyId = ‘contact’; } else if(eregi(’^/work/’,$path) == 1) { $bodyId = ‘work’; } else if(eregi(’^/play/’,$path) == 1) { $bodyId = ‘play’; } else if ($path == ”) { $bodyId = ‘home’; } else { $bodyId = ‘general’; } } return $bodyId; } ?>

    add both sections to your wp header and footer theme file:

    add_action('wp_head', 'setBodyId');
    add_action('wp_footer', 'setBodyId');

    call the wp_head hook from your header:

    <?php wp_head(); $bodyId = setBodyId(); ?>
