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'); ?>
