What happens on the user’s side is off topic as @bungeshea said already. Once the user has loaded the file it will stay in the browser cache for a while, so you don’t have to worry about double loaded files anyway. But let’s look at the server side and how WordPress handles this. If you … Read more
You should do this in the shortcode/plugin itself. An easy way to do it may be something like this: // if the shortcodes empty: if ( empty( $shortcode_content ) ) { // set a default nothing found message $shortcode_content=”Sorry! Nothing found”; } return $shortcode_content;
WordPress never makes any HTTP requests for gravatars, it just generates URLs to them. You don’t really need to override function completely. You can filter get_avatar hook and return different URL if email matches user with custom avatar set.
Hi @NetConstructor: First thing, assuming your logic worked you can use the ternary operator to simplify your example: <li id=”kids-<?php echo is_term(‘Kids’,’age_groups’) ? ‘on’ : ‘off’; ?>”>Kids Programs</li> The issue seems to be that is_term() is used to check if a term exists, not if it is associated with a particular post. I think what … Read more
Syntax is wrong you need to phrase it like so: condition ? TRUE : FALSE so change your code to : echo is_home() ? ‘1’ : ‘0’;
This gets asked a lot so lets try and fully explain it. We can simply wrap it in an if statement and echo the value, for example, <?php if ( get_post_meta($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 function has_type( $type, $_post = null ) { if ( empty( $type) ) return false; if ( $_post ) $_post = get_post( $_post ); else $_post =& $GLOBALS[‘post’]; if ( !$_post ) return false; $r = is_object_in_term( $_post->ID, ‘type’, $type); if ( is_wp_error( $r ) ) return false; return $r; } Usage: <?php if … Read more
Yes, that’s good. You can be a little safer using <?php if(current_user_can(‘manage_plugins’) ); ?>
look for the string page/ and capture just the part of the url before it with strpos and substr: $url=”/players/type/pros/page/3/”; $find = ‘page/’; $trimmed_url = substr( $url, 0, strpos($url, $find) ); EDIT – so in the context of your question you could use: $url = $_SERVER[‘REQUEST_URI’]; $find = ‘page/’; $pos = strpos($url, $find); if($pos): $url … Read more
To filter the content only when an auto-excerpt is generated you have to chain the hooks: Hook into get_the_excerpt and register a filter for the_content. In the second filter remove both elements and their content before the excerpt can see it. Sample: add_filter( ‘get_the_excerpt’, ‘t5_excerpt_clean_up’, 1 ); /** * Register handler for auto-generated excerpt. * … Read more
