Network activation will activate a plugin for every site in a network whereas regular activation will only activate a plugin for the site you’re currently on. As far as implementation goes, there is one other important difference: If your plugin is built to do something when it’s activated (via register_activation_hook()), this will fire automatically when … Read more
I tested this and it works for removing the categories dropdown on the All Posts page: add_action( ‘load-edit.php’, ‘no_category_dropdown’ ); function no_category_dropdown() { add_filter( ‘wp_dropdown_cats’, ‘__return_false’ ); } — below: old answer when I misunderstood the question — The code you posted works just fine for me. But here’s an alternative you might try: add_filter(“manage_posts_columns”, … Read more
Directly accessing the filesystem for writing is evil… for most of the cases where people are actually doing that. If you’re editing an image file, and it is in the wp-content/uploads directory, then you know, whatever. That’s not the common case. Plugins and themes don’t typically do that because they don’t have to do that. … Read more
Just a suggestion and not necessarily the answer, but some of those are so basic I’m wondering if using the Starkers theme from Elliot Jay Stocks and just adding a bit of style to it, could make the simple theme you’ve been looking for.
Sure. wp_install_defaults() is a pluggable function. (As are wp_new_blog_notification() and wp_upgrade(), in case you ever need to override those too.) # in wp-config.php if ( defined(‘WP_INSTALLING’) && WP_INSTALLING ) { include_once dirname(__FILE__) . ‘/wp-content/install.php’; } # in wp-content/install.php function wp_install_defaults($user_id) { global $wpdb, $wp_rewrite, $current_site, $table_prefix; // do whatever you want here… }

You can have a custom field (e.g., “order”) and use it to indicate the order of your posts. You then need to use a custom query to order these posts when they are displayed. You … Read more
The problem is that in a url the ‘+’ sign is equivalent to a space so that’s how PHP sees it. If you use an action on parse_request you can make this work like so: add_action( ‘parse_request’, ‘category_search_logic’, 11 ); function category_search_logic( $query ) { if ( ! isset( $query->query_vars[ ‘cat’ ] ) ) return … Read more
Caution: very mac/linux/unix centric thoughts ahead. Includes a lot of command line fu. Put All the Code Under Version Control I like git. Mark Jaquith has some good suggestions on keeping an entire site under version control using git and submodules for the WordPress core. You could also put plugins in as git submodules. The … Read more
First off, you should not register functions loose in functions.php because you cannot remove them (using remove_action). It can also cause debug errors since WP may not yet be stable. By using a hook you are making sure WP is stable enough to run your code, and what you need to use has been loaded. … Read more
Working Example in Oct 2020, Working answer, I went to different answers none of them works now in new WordPress. function hide_categories_for_specific_user( $exclusions, $args ){ if ( ((defined( ‘REST_REQUEST’ ) && REST_REQUEST) or $GLOBALS[‘pagenow’] === ‘edit.php’ ) && !current_user_can( ‘manage_options’ ) ) { // IDs of terms to be excluded $exclude_array = array(“12″,”16″,”17”); // CHANGE … Read more
