You are getting this error because your class ass no method named widget which is a must to properly use the widgets api. Meaning that each class/widget that extends the WP_Widget class must have a method named widget which is responsible for the actual widget display. So consider this structure as a widget class skeleton: … Read more
You’ve changed from sidebar-main in your myfunc_sidebars_init() to sidebar1 in sidebar.php. Change sidebar.php to use <?php if ( is_active_sidebar( ‘sidebar-main’ ) ) : ?> <?php dynamic_sidebar( ‘sidebar-main’ ); ?>
There are many solutions to your problem, I guess. Two solutions I would recommend are: 1. Register multiple sidebars. Register more sidebars and then include them conditionally in page templates. So if you need different sidebar for each category (let’s say you have 2 categories), then register 2 more sidebars (sidebar-cat-1, sidebar-cat-2) and then replace … Read more
Look at WordPress’s documentation on AJAX In your theme or plugin, you’ll want to have code like: add_action(‘wp_ajax_my_load_recent’, ‘my_load_recent_posts’); add_action(‘wp_ajax_nopriv_my_load_recent’, ‘my_load_recent_posts’); function my_load_recent_posts() { $args = array( /* Arguments go here, i.e. how many posts to get */ ); query_posts($args); /* [1] */ /* Header wrap output */ if (have_posts()) : while (have_posts()) : the_post(); … Read more
First of all I can say why your code doesn’t work. The custom css is created inside the widget function that is called by WordPress in the moment that the widget is displayed. I guess, that you on document ready send an ajax request that call advanced_widget_pack_css() function. But every ajax request is a completely … Read more
It’s likely not anything you are doing wrong but, rather, a misbehaving plugin. There is a lot of ugly code out there that causes widget zones to freak out on the admin side. Try killing all of your plugins first, do you still have the problem? If not, turn them back on a few at … Read more
Where? The WP_Comment_Query class has the following filter for its clauses: $pieces = array( ‘fields’, ‘join’, ‘where’, ‘orderby’, ‘order’, ‘limits’, ‘groupby’ ); $clauses = apply_filters_ref_array( ‘comments_clauses’, array( compact( $pieces ), &$this ) ); That means you can hook into comments_clauses and filter the $clauses[‘where’] part. How? Since WP 3.7, we got a WP_Date_Query class. It … Read more
Sorry, I was just hooking into the wrong filter. My add_filter should have hooked into widget_categories_args not widget_categories_dropdown_args.
I guess “easy” is a relative term. Yes, you can create your own. For adding an admin page there are a glut of tutorials out there. This one works (and has some other info you might need) http://wp.smashingmagazine.com/2011/03/08/ten-things-every-wordpress-plugin-developer-should-know/. Search for “Add Your Own Settings Page or Admin Menu” on the page. jQuery UI is loaded … Read more
You should check that the variable exists before using it. isset() will return true if a variable has been set and is not null. For example: update_post_meta($post->ID, “_sidebar”, $_POST[“link”]); will become: if ( isset( $_POST[“link”] ) ) { update_post_meta( $post->ID, “_sidebar”, $_POST[“link”] ); } As an aside, it’s a good idea to validate your data … Read more
