wordpress: back to (grand)parent

was challenged at work and couldn’t think of a proper solution. i knew it was possible, but didn’t know how to execute it

this is what happens when you don’t know all the tools you have available to you…

thank god for the wordpress community

background

this makes absolutely no sense without any background! essentially i have a splash page that goes to several sub-sites. when you get to a sub-site, i want each sub-site’s home to go back to its own home location, not the splash page, which would be 

< ?php echo get_option('home'); ?>

code

< ?php //parent variables
	$parent = get_post($post->post_parent);
	$parent_title = get_the_title($parent);
	$grandparent = $parent->post_parent;
	$grandparent_title = get_the_title($grandparent);?>

	< ?php // is the homepage the granparent?
	if ($grandparent == is_page('0')) { ?>
	<li><a href="/<?php echo get_permalink($grandparent); ?>">Back to < ?php echo $grandparent_title; ?></a></li>
	<li><a href="<?php echo get_permalink($post->post_parent); ?>">Back to < ?php echo $parent_title; ?></a></li>

	< ?php // is the homepage the parent?
	} elseif ($post->post_parent ==is_page('0')) {?>
   <li> <a href="<?php echo get_permalink($post->post_parent) ?>">Back to < ?php echo $parent_title; ?></a></li>

    < ?php // I must be a top level page!
	} else { ?> <!-- no parent to show -->
< ?php }?>

wordpress php snippets

here are a bunch of frequently used code snippets i’ve used with many of my projects

* i really should know these by now… but what are ya gonna do?

linking to the homepage

    <a href="<?php echo get_option('home'); ?>">...</a>

    image references

      <img src="<?php bloginfo('stylesheet_directory'); ?>/images/FILE_NAME.jpg"
alt="<?php bloginfo('name'); ?>" title="<?php bloginfo('name'); ?>" />

      dynamic widgets

        <?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('WIDGET_NAME') ) : ?>
<?php endif; ?>

        then, in functions.php, add this:

        register_sidebar(array('name'=>'WIDGET_NAME',
'before_widget' => '',
'after_widget' => '',
'before_title' => '<h3>',
'after_title' => '</h3>',
));

        custom fields – mentioned before on my site, but just to have ’em all together

          <?php $VARIABLE_NAME=get_post_meta($post->ID, "CUSTOM_FIELD_NAME", true);
if (get_post_meta($post->ID, "CUSTOM_FIELD_NAME", true)) {
echo ("<img src=\"FULL_PATH_TO/$VARIABLE_NAME\" />");
} ?>

          copyright

            &copy; <?php echo date('Y'); ?> - <?php bloginfo('name'); ?>

            wordpress: creating your own custom theme

            hot on the heels of my first tutorial, i come back at ya with a new one.

            i REALLY like using wordpress as a cms — not only for its ease of customization or its extensive library of useful (mostly) plugins, but for these two huge reasons:

            1. ability for the end-user to modify the web site content without breaking the overall site geography
            2. search engine optimization — yea i kinda did mention them earlier, but several plugins can work to help your site get spidered like the best of them.

            so i guess that answers the “why use wordpress?” question — here’s my method of getting a custom theme setup for wordpress

            wordpress: change your home page to a custom page

            so chaunce asked if i could do a small tutorial for a wordpress (wp) question he had… i’m honored that he asked me to do so… actually, i think i might start to write a bunch of tutorials that i’ve learned along the way…

            and here… we… go…

            this tutorial deals with the user wanting a site with a blog and pages, but the user wants a specific page to be the front page, not the blog (something similar to andy’s site, but not — since he doesn’t want his site to be full-on wordpress)

            *note, i suck at technical writing, but i’ll try to fake it… i’m open to suggestions/comments for future tutorials
