I have created 3 custom widgets named Prakash Category Widget, Prakash Author Widget and Prakash Tag Widget. Their codes are:
<?php
// Begin Prakash Category Widget
/*
Plugin Name: Prakash Category Widget
Description: A Simple Category Widget
Version: 1.0
Author: Prakash Pazhanisamy
Author URI: http://prakashpazhanisamy.wordpress.com
*/
class CategoryWidget extends WP_Widget
{
public function __construct() {
parent::__construct("text_widget", "Prakash Category Widget",
array("description" => "A Simple Category Widget"));
}
public function widget($args, $instance) {
$cats = get_categories(); // Get categories
if ($cats) :
echo '<h2>Categories</h2>';
echo '<ul>';
foreach ($cats as $cat) {
// Create a query for the category to determine the number of posts
$category_id= $cat->term_id;
$cat_query = new WP_Query( array( 'post_type' => 'post',
'posts_per_page' => -1,
'cat' => $category_id
) );
$count = $cat_query->found_posts;
// Print each category with it's count as a list item
echo "<li>" . $cat->name . " (" . $count . ")</li>";
}
wp_reset_query(); // Restore global post data
echo '</ul>';
endif;
}
}
add_action("widgets_init", function () { register_widget("CategoryWidget"); });
// End Prakash Category Widget
?>
<?php
//Begin Prakash Author Widget
/*
Plugin Name: Prakash Author Widget
Description: A Simple Author Widget
Version: 1.0
Author: Prakash Pazhanisamy
Author URI: http://prakashpazhanisamy.wordpress.com
*/
class AuthorWidget extends WP_Widget
{
public function __construct() {
parent::__construct("text_widget", "Prakash Author Widget",
array("description" => "A Simple Author Widget"));
}
public function widget($args, $instance) {
global $wpdb;
$authors = $wpdb->get_results("SELECT ID, user_nicename from $wpdb->users ORDER BY display_name");
echo "<h2>Authors</h2>";
foreach($authors as $author) {
echo "<li>";
echo "<a href=\"".get_bloginfo('url')."/?author=";
echo $author->ID;
echo "\">";
echo get_avatar($author->ID);
echo "</a>";
echo '<div>';
echo "<a href=\"".get_bloginfo('url')."/?author=";
echo $author->ID;
echo "\">";
the_author_meta('display_name', $author->ID);
echo "</a>";
echo "</div>";
echo "</li>";
}
}
}
add_action("widgets_init", function () { register_widget("AuthorWidget"); });
//End Prakash Author Widget
?>
<?php
//Begin Prakash Tag Widget
/*
Plugin Name: Prakash Tag Widget
Description: A Simple Tag Widget
Version: 1.0
Author: Prakash Pazhanisamy
Author URI: http://prakashpazhanisamy.wordpress.com
*/
class TagWidget extends WP_Widget
{
public function __construct() {
parent::__construct("text_widget", "Prakash Tag Widget",
array("description" => "A Simple Tag Widget"));
}
public function widget($args, $instance) {
$terms = get_terms('post_tag',array('hide_empty'=>false));
echo "<h2>Tags</h2>";
foreach($terms as $t) {
echo $t->name.' ('.$t->count.')</br>';
}
}
}
add_action("widgets_init", function () { register_widget("TagWidget"); });
//End Prakash Tag Widget
?>
All the above 3 files are located in plugins folder. After activating all the 3 plugins, all custom widgets are not showing in widget area at the same time. It is showing only any one of the widget. Help!
