How to set the default value of a option in a theme?

As @Ashfame as already pointed out, you shouldn’t store defaults in the database – that should be for user selected options (of course, if they select the defaults, then fine – store them :). However, you don’t need to use wp_parse_args() either. get_option allows you to select a default value. For instance: //If nuod_logo is … Read more

Override Current Theme Setting in wp_config.php

Drop this in a plugin & activate. I should note this doesn’t take into account things like child themes – it’s purely for toggling which theme renders based on SOME_FLAG. add_filter( ‘stylesheet’, ‘switch_ma_theme’ ); add_filter( ‘template’, ‘switch_ma_theme’ ); function switch_ma_theme() { // Return the theme directory name return SOME_FLAG ? ‘theme-1’ : ‘theme-2’; }

You can do this by using pre_get_posts() which will adjust the query before it’s run. Therefore we can exclude pages from the query. function wpse_hide_special_pages($query) { // Make sure we’re in the admin and it’s the main query if ( !is_admin() && !is_main_query() ) { return; } // Set the ID of your user so … Read more

How to disable 3.1 “Admin Bar” via script for the admin user?

You could use a function inside your theme’s functions file to selectively disable it for specific users. function disable_bar_for_user( $ids ) { if( !is_user_logged_in() ) return; global $current_user; if( is_numeric( $ids ) ) $ids = (array) $ids; if( !in_array( $current_user->data->ID, $ids ) ) return; add_filter( ‘show_admin_bar’, ‘__return_false’, 9 ); } Then call it for the … Read more

What can I hook into after_setup_theme?

Think of WordPress execution as a series of rungs on a ladder: WordPress climbs one rung, then the next, then the next, and so on. Think of action hooks as the rungs themselves. Here is a (slightly abbreviated, I think) list of those actions, or “rungs” executed during a typical WordPress request. Thus, an add_action() … Read more

Child Theme not loading parent CSS

Take a look at How to create a Child Theme and you’ll see that: the previous method to enqueue the parent stylesheet was to import the parent theme stylesheet using @import: this is no longer best practice. The correct method of enqueuing the parent theme stylesheet is to add a wp_enqueue_scripts action and use wp_enqueue_style() … Read more
