You need to implement your Widget using the Widgets API, so that WordPress knows how to make multiple instances of the Widget. Your Widget declaration should take the following format: class My_Widget extends WP_Widget { function My_Widget() { // widget actual processes } function form($instance) { // outputs the options form on admin } function … Read more
check your sidebar.php and functions.php of the theme, the sidebar define the markup outside the widget; the function register_sidebar() defines the markup before content of the widgets; this markup you must change. See the codex for this function: codex register_sidebar() Edit Specifically, you need to look at the before_widget and after_widget parameters of the register_sidebar() … Read more
This is sort of sloppy as the style will still be enqueued regardless. In the code to display your widget, change the CSS selectors based on whether or not the user selected own style: <?php $prefix = $instance[‘own_style’] ? ‘ownstyle_’ : ‘pluginstyle_’; //then…. ?> <div id=”<?php echo $prefix; ?>selector”> …</div> etc A user would be … Read more
If I understand correctly you want to include a php file that validates the form input, but only when you need to actually validate something? In this case, you don’t need to check if the contact form exists on some page – you just need to check if the form data has been posted. All … Read more
Does unregistering them the also disable the database queries? Goes in functions.php: //Unregister all Default Widgets function unregister_default_wp_widgets() { unregister_widget(‘WP_Widget_Pages’); unregister_widget(‘WP_Widget_Calendar’); unregister_widget(‘WP_Widget_Archives’); unregister_widget(‘WP_Widget_Links’); unregister_widget(‘WP_Widget_Meta’); unregister_widget(‘WP_Widget_Search’); unregister_widget(‘WP_Widget_Text’); unregister_widget(‘WP_Widget_Categories’); unregister_widget(‘WP_Widget_Recent_Posts’); unregister_widget(‘WP_Widget_Recent_Comments’); unregister_widget(‘WP_Widget_RSS’); unregister_widget(‘WP_Widget_Tag_Cloud’); } add_action(‘widgets_init’, ‘unregister_default_wp_widgets’, 1);
One way around this I’ve discovered since posting the above question is to instantiate inline via WP_Widget::form(), with wp_enqueue_script() loading the necessary JavaScript (exactly as mentioned above) — except, and here’s the key part, load the JavaScript in the header instead of the footer (fifth argument of wp_enqueue_script()). Which makes a lot of sense now … Read more
To quote the Codex The return value should be used to determine whether to display a static sidebar. This ensures that your theme will look good even when the Widgets plug-in is not active. So essentially you can use is to display other content if the user has not activated any widgets in the sidebar.
There actually are filters coming with WP 3.9+: do_action( ‘dynamic_sidebar_before’, $index, false ); do_action( ‘dynamic_sidebar_after’, $index, false ); apply_filters( ‘dynamic_sidebar_has_widgets’, false, $index ); The 2nd argument indicates if the sidebar has widgets. Current workaround: Hook into sanitize_title() as this will hold the current sidebar name/ID. Then hook into wp_get_sidebars_widgets() as this is where you already … Read more
You don’t need to worry to much about your query as there is not much you can do about it. You can unfortunately not just only query categies, post titles and images natively using WP_Query. Post categories needs to be called separately inside the loop, just like featured images. If you dig deeper into core, … Read more
As per the last comment, this is the correct answer: $paged = get_query_var( ‘page’, 1 ); if(1 != $paged) …
