WP_Query goes only through posts by default. Try adding page as your post type: $the_query = new WP_Query(array( ‘post_type’ => ‘page’, /* overrides default ‘post’ */ ‘meta_key’ => ‘_wp_page_template’, ‘meta_value’ => ‘templates/_partner.php’ )); See: WP_Query – Type Parameters
The cart widget isn’t showing because it’s configured to not show on the cart and checkout page.

Filter widget_text (for the text) widget_title (for the title) Example function add_smiley($content) { $new_content=””; $new_content.= $content . ‘:)’; return $new_content; } add_filter(‘widget_text’, ‘add_smiley’); Note that this works only for the content so not if you have a widget with only a title.

Add a widget area to your single.php, front-page.php, home.php or whatever you want.. template’s theme file. Than at the back-end go to Appearance > Widgets and move the widget to the widget area you just created.
The Widgets API is the quickest way to make a widget that’s reusable. Example use: class My_Widget extends WP_Widget { /** * PHP4 constructor */ function My_Widget() { My_Widget::__construct(); } /** * PHP5 constructor */ function __construct() { // actual widget processes } /** * Echo the settings update form * * @param array $instance … Read more
The error isn’t actually caused by your PHP version (PHP 4 constructors won’t be removed until PHP 7) – it’s a warning produced by WordPress in preparation for this. Each repetition of the error represents a plugin using the outdated code. Until your plugins’ authors update them, you can run the following shell command on … Read more
You can get the instance ID with echo $this->id; ($this is the class instance) The only time you can’t get this id is from the form() function, right after you just dropped the widget (here‘s the reason why)
Put simply: not inherently. If you have a widget that does NOTHING at all…like, literally you add it and there’s no code for the widget outside of registering it, you’ll see SUCH a small performance hit from adding it that you would need to be looking at microtime() numbers to notice anything. That said, as … Read more
