It’s fun! 🙂 Anyway … <?php $meta = get_post_meta( get_the_ID(), ‘rw_agentPhone’, TRUE ); // get_post_meta() returns an empty string if it doesn’t find anything. // We just test for this. If the string is not empty, we print it out. ” != $meta and … Read more

You could also use wp_list_pages() (Codex ref): <?php $has_pages = wp_list_pages( array( ‘echo’ => false ) ); if ( $has_pages ) { // There are pages; do something } ?>
is_category() takes an array as arguments if you want to check for more than one category. But you can make it even easier with a check for existing files: if ( is_category() ) { $slug = get_queried_object()->slug; $theme_path = “/images/slider_$slug.png”; $file = get_template_directory() . $theme_path; if ( file_exists( $file ) ) { echo ‘<img src=”‘ … Read more

I’m not sure if lang is a reserved/used query variable in WordPress, but if it’s not, then adding might help. Use a filter on query_vars like this: function my_query_vars( $vars ) { $vars[] = ‘lang’; return $vars; } add_filter( ‘query_vars’, ‘my_query_vars’ ); Although WordPress will now know about the language query variable, I’m not sure … Read more
Try adding global $post; to the function, so that the $post variable will be available within the function’s scope. Also, make sure your code is executing inside The Loop. If the function is executing too early, then $post may not be available. If neither of those things work, please post the full function and any … Read more
You can do that via echo, just place it on a new line inside the if conditionals braces { and } e.g. if(this statement is true) { // <- do everything between here /* stuff that happens if the statement is true */ } // <– and here else { // stuff that happens if … Read more
