If you look at the source for the home_url() function, you’ll note a small series of function calls eventually invoking get_option(). As explained in this WPSE Answer, the get_option() function is cached, meaning that if an option’s value is already in memory, get_option() returns that value instead of querying the database again. As a result, … Read more
This is a PHP question not related at all to WP, but since it was upvoted…. TL;Dr version – Compilres do this kind of micro optimizations much better then you, no point in even trying. lets look at what compilers will do with your question code // is this less efficient $meta = get_post_meta($post->ID,’meta’); $permalink … Read more
You need to check the actual access logs, such as web, SSH, etc., and if you can access it, the MySQL log, too. That will show you what is possibly hitting the site at that time and let you differentiate between a huge unexplained web traffic spike from a bot and something that is happening … Read more
Defining WP_HTTP_BLOCK_EXTERNAL constant (wp-config.php is good place to do this) would kill all outgoing network requests, other than those for hostnames, defined in WP_ACCESSIBLE_HOSTS. See source for details, doesn’t seem to be documented in Codex.
In my opinion you are focusing on a wrong issue in this case. For instance, if I want to change the Read More message I have to browse all files to see if it is there. This doesn’t indicate localization problem. This indicates templating problem. What if you want to change markup of Read More … Read more
The overhead of PHP function as a mechanism is minimal. After all nearly everything going on is function calls. On a reasonable hardware you will have to ramp up function calls into thousands and tens of thousands to generate significant overhead (as opposed to doing same things with less function calls involved). Worth noting that … Read more
You can do it like this, put it in your functions.php : This is the correct way of doing it “the WordPress way”. <?php // Check if function exisits if (!function_exists(‘rg_templateScriptSetup’)) { // if not, create one function rg_templateScriptSetup() { // Register styles in WordPress wp_register_style(‘prefix-basic-css’, get_template_directory_uri(). ‘/css/basic-style.css’); // Register styles in WordPress wp_register_style(‘first-css’, get_template_directory_uri(). … Read more
Siteground has WP-CLI installed and when you have WooCommerce installed it adds its own set of WP-CLI commands. See this: https://github.com/woocommerce/woocommerce/wiki/WC-CLI-Overview With this your solution would be cleaner as it would go though WC’s API. Maybe you can also check for ideas how WC does it. I remember in the add/edit product UI there was … Read more
Depends on the use case. But 100 def. says there’s something gone wrong. If you got a lot of custom tables and a lot of different stuff from different tables that you need to display on one page/request, then I’d say 40 is higher than usual. My personal framework does around 10-15(?) queries for a … Read more
You can get rid of most of your code above. WP_User_Query has an include parameter (introduced in WordPress 3.9) include (array) – List of users to be included. So we need to get a random array of author ID’s. I have modified your count_users_with_posts() a bit here to extend it to make it more dynamic … Read more
