It depends on where you want to put the ‘hello’ thing. For instance, you could use the_content filter to put it before or after the content: function wp_add_to_the_content($content) { $content=”Text before the content.” . $content . ‘Text after the content’; return $content add_filter(‘the_content’, ‘wp_add_to_the_content’,10,1); You’d need to add any CSS and other tags to format … Read more

You probably want to drop the conditional during init. You are just registering the script here, not enqueueing it. Once registered, you should be able to call the script later in the action sequence. Please try something like this: function myplugin_css() { if ( is_page( ‘myinfopage’ ) ) { wp_enqueue_script( ‘RGraph’ ); } } add_action( … Read more

It’s untested, but should work. $expireDays=”15″; $querystr = ” SELECT $wpdb->posts.* FROM $wpdb->posts, $wpdb->postmeta WHERE $wpdb->posts.ID = $wpdb->postmeta.post_id AND $wpdb->posts.post_status=”publish” AND $wpdb->posts.post_type=”post” AND $wpdb->posts.post_date >= ( CURDATE() – INTERVAL $expireDays DAY ) ORDER BY $wpdb->posts.post_date DESC “; $pageposts = $wpdb->get_results($querystr, … Read more
You can handle this much more simply with CSS and a print stylesheet. Just add display:none within that stylesheet for all elements you don’t want visible in the print version.
Use has_nav_menu to check if a location has been assigned a menu or not <?php if ( has_nav_menu( $location ) ) { echo “Also in this section”; } ?> http://codex.wordpress.org/Function_Reference/has_nav_menu For more advanced checks you’ll need to do a call to wp_get_nav_menu_items and process the items it returns to see if any of them are … Read more
