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'); ?>
