Try this code. class Image_Picker extends WP_Widget { function Image_Picker() { $widget_ops = array(‘classname’ => ‘Image_Picker’, ‘description’ => ‘Pick 2 images from media library’); $this->WP_Widget(‘Image_Picker’, ‘Image Picker’, $widget_ops); } function form($instance) { //WIDGET BACK-END SETTINGS $instance = wp_parse_args((array) $instance, array(‘link1’ => ”, ‘link2’ => ”)); $link1 = $instance[‘link1’]; $link2 = $instance[‘link2’]; $images = new WP_Query( … Read more
Someone may correct me, but I think as of Version 3.3 you can enqueue scripts and styles “inline” of a post. Means: you can add your wp_enqueue_script / style inside your shortcode function and WordPress will add them to the footer…since it’s too late to add them to the header. Means: It will just work … Read more
Looking at widget.php in trac sprintf() only runs on before_widget (Line 884): $params[0][‘before_widget’] = sprintf($params[0][‘before_widget’], $id, $classname_); Hence, it won’t work for any of the other arguments. I wondered whether you could use the dynamic_sidebar_params filter, but the $id and $classname_ arguments aren’t passed on to the filter. Outside of hacking core, I’m not sure … Read more
wp_enqueue_scripts is called way before WordPress processes the widget content, so just as in this post, you’ve missed the boat :). Instead, just call wp_enqueue_style directly: function widget($args, $instance) { wp_enqueue_style( ‘myprefix-style’, plugins_url(‘mystyle.css’, __FILE__) ); //Widget content } (no need to register if you’re just going to enqueue it straight after). Same works for wp_enqueue_script.
Use Conditional Tags to show content only if a certain condition is met. In your case, you’re probably looking to use is_front_page(). <aside> <ul> <?php if ( function_exists( ‘dynamic_sidebar’ ) ) { if ( is_front_page() ) { if ( ! dynamic_sidebar( ‘frontpage-widget-area’ ) ) { echo ‘<li>No sidebars for the frontpage.</li>’; // some default output … Read more
It sounds like you’ll need the plugins_url() function which generates the URL for the plugins directory and can handle any alternate configuration (such as if you moved it to the /mu-plugins/ directory, a personal favorite of mine). The Codex documentation is good, but here’s a quick example. Let’s say you’re making this in a plugin … Read more
It sounds like you’re trying to add a new widget area (dynamic sidebar) to your Theme. That process has three parts: Register the dynamic sidebar in functions.php, using register_sidebar(): function wpse121723_register_sidebars() { register_sidebar( array( ‘name’ => ‘Home right sidebar’, ‘id’ => ‘home_right_1’, ‘before_widget’ => ‘<div>’, ‘after_widget’ => ‘</div>’, ‘before_title’ => ‘<h2 class=”rounded”>’, ‘after_title’ => ‘</h2>’, … Read more
Widget data is stored in the options table as a two dimensional array. All data for the same type of widget is stored under the same option key. The key of the outer array is a kind of widget “index”– the identifier for the particular instance of the widget. The inner arrays contain the individual … Read more
This notice appears when you try to access an undefined index of an array. To fix this, you’ll need to check if the index exists before you access it. For this you can use isset() or array_key_exists(): I’d need to see the exact line of code that the notice is referring to (line 26) in … Read more
1 In your main plugin file (zero.php), you have invalid instantiation of your plugin object. You’re trying to create an object inside an object which doesn’t exist yet. Note: It is possible to create objects within objects, however, you must first create the initial object from the “outside world” (so to speak — or A/K/A … Read more
