Change management in WordPress

I have a beginner question. What is the best way to address the change management issues in WordPress? I have an all-pages WordPress installation. Suppose name of some event or an entity changes from A to B, then I have to go to all the pages to make that change. Is there any better way of doing it? Like externalization or something. Or 开发者_如何转开发the way similar to how WordPress handle blog name using bloginfo() function. You change blog name at one place and it is reflected everywhere.

Thanks, Paras

If a URL on your site changes, it is always wise to leave a redirect to the new page. This will help your visitors and search engines. If you create redirects, it doesn't matter too much if you still have a link to the old address in one of your posts. There will probably be a plugin for this, but I don't know which one.

If you really want to keep all links pointing to the latest version, you could replace them with shortcodes that are evaluated to the real URL. <a href="[linkto postid=123]"> would then result in <a href="/2010/08/05/some-post">. I think this is doable, but I don't know whether a plugin already exists for this.

You can also use this technique to replace short snippets, like your company name. The Shortcode API is really easy:

// [company_name]
function replace_company_name($atts) {
    return "My Awesome Company";
}
add_shortcode('company_name', 'replace_company_name');


// More generic
// [replace r='company_name']
// [replace r='company_motto']
function do_replacement($atts) {
    $replacements = array(
        'company_name' => 'My Awesome Company',
        'company_motto' => 'A Company so Awesome even you would want to work here!',
    );

    return $replacements[$atts['r']];
}
add_shortcode('replace', 'do_replacement');

You can hardcode the strings in your plugin code, or you could create a Wordpress options page where users can add and edit new shortcodes.
