WordPress How to Build a WordPress Plugin Building WordPress Widgets, and Shortcodes WordPress Widgets Code Challenges

4/6 - WordPress Widgets Code Challenges

"Inside of the widget function, below the extract function, apply the widget_title filter to get the title of the instance. Assign it to a variable named title."

I feel like I'm missing something obvious. I've got the right variable name, $title is in the right location, the filter appears to be written correctly.

What am I missing?

function widget($args, $instance) {
    extract($args);
    $title = apply_filters('widget_title', $instance['title']);
}

Thanks

Your code is correct. However, when I went through the challenge, I got an error and then I moved the code to different lines to make it work. Here is my full code that passed that test. I deleted the comments on that section and put the extract there and then got it to work. Maybe there's something weird with how they check the result there?

<?php

    class My_Plugin_Widget extends WP_Widget {

        function my_plugin_widget() {
            parent::__construct( false, 'My Plugin Widget' );
        }

    function widget( $args, $instance ) {
        extract( $args );
    $title = apply_filters('widget_title', $instance['title']);
    }

    function update( $new_instance, $old_instance ) {
        // Save widget options
    $instance = $old_instance;
    $instance['title'] = strip_tags($new_instance['title']);
    return $instance;
    }

    function form( $instance ) {
        // Output admin widget options form
    $title = esc_attr($instance['title']);
    require('inc/widget-fields.php');
    }
}

That was quite the ordeal. Must have been a bug. I guess a few code challenges would be buggy out of dozens.

Thanks for your help.

Below the My_Plugin_Widget class, add a function named my_plugin_register_widgets that registers the widget.

here is my code ... not working ... why ?

class My_Plugin_Widget extends WP_Widget {

function my_plugin_register_widgets() {
register_widget( 'WP_Widget' );

}

    function my_plugin_widget() {
        parent::__construct( false, 'My Plugin Widget' );
    }


function widget( $args, $instance ) {
    extract( $args );
$title = apply_filters('widget_title', $instance['title']);
}

function update( $new_instance, $old_instance ) {
    // Save widget options
$instance = $old_instance;
$instance['title'] = strip_tags($new_instance['title']);
return $instance;
}



function form( $instance ) {
    // Output admin widget options form
$title = esc_attr($instance['title']);
require('inc/widget-fields.php');
}



}
