Adding Custom Widgets to WordPress Sidebar
Posted on 17th June 2023
In this article, we will show you how to add custom widgets to your WordPress sidebar.
WordPress comes with a powerful widget API that allows you to create your own widgets. Widgets are small pieces of functionality that you can add to your site. For example, a recent posts widget, a social media widget, etc.
The WordPress widget API is very simple to use. It only requires you to register your widget with WordPress and then implement a few methods to display the widget content.
In this article, we will show you how to create a custom widget and add it to your WordPress sidebar.
Before we begin, please note that you will need to have a basic understanding of PHP and HTML to be able to add custom widgets to your WordPress sidebar.
Creating a Custom Widget
First thing you need to do is to create a new file called “My_Widget.php” in your WordPress theme’s folder.
You can add the following code to your newly created file:
‘my_widget’, ‘description’ => __(‘A custom widget to display recent posts.’, ‘text_domain’) );
$this->WP_Widget( ‘my_widget’, __(‘My Widget’, ‘text_domain’), $widget_ops );
}
function widget( $args, $instance ) {
extract( $args );
echo $before_widget;
if ( !empty( $instance[‘title’] ) ) {
echo $before_title . apply_filters( ‘widget_title’, $instance[‘title’] ). $after_title;
}
echo __( ‘Hello, World!’, ‘text_domain’ );
echo $after_widget;
}
function update( $new_instance, $old_instance ) {
$instance = $old_instance;
$instance[‘title’] = strip_tags( $new_instance[‘title’] );
return $instance;
}
function form( $instance ) {
$title = isset( $instance[‘title’] ) ? $instance[‘title’] : __( ‘Recent Posts’, ‘text_domain’ );
?>
<label for="get_field_id( ‘title’ ); ?>”>
<input class="widefat" id="get_field_id( ‘title’ ); ?>” name=”get_field_name( ‘title’ ); ?>” type=”text” value=”” />
This code creates a custom widget called “My Widget” and adds it to your WordPress sidebar.
Adding Your Custom Widget to the Sidebar
Once you have created your custom widget, you can add it to your sidebar from the Widgets page in your WordPress admin area.
Simply drag and drop the widget to the sidebar where you want it to appear.
Adding CSS Styles to Your Custom Widget
If you want to style your custom widget, you can add the following CSS code to your WordPress theme’s style.css file.
.my_widget {
border: 1px solid #ddd;
padding: 10px;
}
.my_widget h3 {
margin: 0 0 10px 0;
}
.my_widget ul {
margin: 0;
padding: 0;
}
.my_widget li {
list-style: none;
margin: 0 0 10px 0;
}
.my_widget li a {
text-decoration: none;
}
This CSS code will style your custom widget to match the default WordPress widgets.
Adding PHP Code to Your Custom Widget
If you want to add PHP code to your custom widget, you can use the “widget_content” filter.
For example, the following code will add a “Recent Posts” widget to your sidebar.
add_filter( ‘widget_content’, ‘my_recent_posts_widget’ );
function my_recent_posts_widget( $content ) {
if ( is_singular( ‘post’ ) && is_active_widget( false, false, ‘my_widget’, true ) ) {
$content .= ‘
- ‘;
- Recent Posts
$content .= ‘
‘;
$content .= ‘
‘;
}
return $content;
}
?>
When you have finished adding text, click on the ‘Publish’ button.
