It seems the problem lies within redefining a widget: a widget with the ID “recent-posts” already exists, and that’s causing some strange behaviour when saving the widget. This is possibly due the callback on saving the widget being on the original widget class WP_Widget_Recent_Posts). It’s not really a good idea anyway to redefine a widget; … Read more
I don’t really think there is a safe way to make changes to your functions file, and for that matter any other template file. And I personally think that the back end editor are a big evil. It is unwise to make any changes to a live site, period. Any type of syntax or fatal … Read more
You can use site_url() or get_site_url(). Depending on your install and setup, you could as well use network_site_url() – which is what I would prefer as it falls back to site_url() internally if it is no multisite setup. The site_url( $path, $scheme ); function also takes two arguments: The $path can be used to append … Read more
You should wrap your condition inside the function, rather than the function inside the condition (this will also prevent errors with code running too early as WordPress loads). function my_admin_notice() { global $wpdb, $post; $depth = $wpdb->get_var( $wpdb->prepare( “SELECT post_parent FROM $wpdb->posts WHERE ID = %d”, $post->ID ) ); if ( $depth == ‘0’ ) … Read more
WordPress is running Jquery in noconflict mode. (WordPress Codex Reference) or read this brief article I posted some time ago. View it here. You need to replace: $(document).ready(function(){ With this: jQuery(document).ready(function($){ So all together, try this: jQuery(document).ready(function($){ $(“#contact_form”).validate({ rules: { name: “required”, email: { required: true, email: true }, message: “required” }, messages: { name: … Read more
It isn’t really WordPress-related indeed, but then again, OP doesn’t seem to know that, so here’s your answer :-). However, next time: this isn’t WordPress-related, please post PHP-questions in the corresponding SE. Sorting a PHP array can be achieved by using the sort function, which sorts an array alphabetically by its values. I’m assuming you … Read more
Use WordPress Transient API instead. This should be something like this (modified your existing shortcode function). function skips_get_random_tags() { $transient_name=”skips_random_tag”; $transient_expiration = 60 * 60 * 24; // 1 day if ( false === ( $tag = get_transient( $transient_name ) ) ) { // tag isn’t found in transient so get it from WP database … Read more
You can write conditionals in your functions.php file to conditionally load the javascript files. For example: function theme_scripts() { // If this is the home page, run this script if(is_home()) { wp_enqueue_script( ‘example-script’, get_stylesheet_directory_uri().’/path/to/file.js’); } // Otherwise, run this script else { wp_enqueue_script( ‘other-script’, get_stylesheet_directory_uri().’/path/to/file.js’); } } add_action( ‘wp_enqueue_scripts’, ‘theme_scripts’ ); Codex page for home … Read more
wp_get_attachment_image_src() takes ID of attachment “post type” (in quotes because it’s native WP post type so not quite same thing as CPT). Now while users are shared in multisite, posts are not. The ID (94) that points to specific attachment in your main site has no meaning whatsoever in any other site of your multisite. … Read more
I think the path to the image is wrong, use get_stylesheet_directory_uri() to retrieve the style.css path. If this isn’t it let me know and I will take a closer look. I just dug out an example which worked for me in the past: function my_login_logo() { ?> <style type=”text/css”> body.login div#login h1 a { background-image: … Read more
