I’m not sure I fully understood your question, but wrapping a function inside a new function will make it shorter. For example, do the following in your functions.php file: function is_parent($slug){ if(is_category($slug)){ return true; }else{ return false; } } And then simply use it like: if(is_parent(‘slug’)){ // do something }
I’d suggest moving the script registering into the init action, and moving the enqueue(s) into a callback hooked onto wp_print_scripts. Eg. add_action( ‘init’, ‘register_those_scriptsNstyles’ ); function register_those_scriptsNstyles() { wp_register_script( .. your script params .. ); wp_register_style( .. your style params .. ); ..etc.. } add_action( ‘wp_print_scripts’, ‘enqueue_those_scriptsNstyles’ ); function enqueue_those_scriptsNstyles() { if( !is_page( ‘some-page’ ) … Read more
WordPress never makes any HTTP requests for gravatars, it just generates URLs to them. You don’t really need to override function completely. You can filter get_avatar hook and return different URL if email matches user with custom avatar set.
This gets asked a lot so lets try and fully explain it. We can simply wrap it in an if statement and echo the value, for example, <?php if ( get_post_meta($post->ID, ‘genre’, true) ) : ?> <?php echo get_post_meta($post->ID, ‘genre, true) ?> ?> <?php endif; ?> But that is ugly, and why do 2 queries … Read more
Try putting a wp_reset_query function call after your loop on the homepage template. If you’re using a custom query on the home page and not used wp_reset_query, then the conditional check will always point to the last post fetched by that custom query hence failing to check if homepage.
Using the code you posted, the selected category’s ID is available in the $_REQUEST, you can check that ID against your products category in the default_content filter and add content if there’s a match: add_filter( ‘default_content’, ‘wpa70073_default_products_content’ ); function wpa70073_default_products_content( $content ) { // change this to your desired category ID $products_category_id = 42; if( … Read more
WordPress has no conditional for substring testing but you can do this using PHPs built-in function: strpos() global $post; if( false !== strpos( $post->post_name, ‘beef’ ) ) { // Do Things } The above returns true if beef is found somewhere in the post slug.
One way to do it is getting the author data and checking it’s role with get_userdata() Codex For that you will need the user ID, and you can get that with get_post_field() Codex You will need the post ID to use the get_post_field(), so you can use the get_queried_object_id()Codex So, you would have something like: … Read more
How about a few simple lines With jQuery? jQuery(document).ready( function ($) { if ($(“.entry-content:first-child”).has(‘img’).length) //this check for the img tag $(“.entry-content:first-child”).after(“<div>MY CUSTOM CODE</div>”); else $(“.entry-content:first-child”).before(“<div>MY CUSTOM CODE</div>”); }); Update: Here is a simple solution using php’s native DOMDocument add_filter(‘the_content’,’add_code_before_afterImage’); function add_code_before_afterImage($content){ $MYCODE = ‘<div>this is my custom code</div>’; $doc = new DOMDocument(); @$doc->loadHTML(‘<?xml encoding=”‘.get_bloginfo(‘charset’).'”>’.$content); $ps … Read more
From quick look at code this conditional only seems to be processed for styles and not scripts.
