music widget in page template - select options - php

Question

I am using the Rockit Now wordpress theme, which comes with a music player widget. When adding the widget to a sidebar, you have the followings options-
Title- (a section to type text..)
Artist for playlist- (a dropdown menu with all artist post names)
No of tracks to play- (a section to type a number..)
I am trying to display this widget in my artist page template so that it appears on each artist page with the music for that particular artist post.
I have added the following to my single-artists.php page template-
<?php the_widget( 'cs_music_player' ); ?>
This has successfully called the widget as I am now receiving the message 'No Results Found' on the page.. What I need to do is be able to select the options as above in the php.. I unfortunately can't work out how to do this..
Here is the cs_music_playlist_widget.php code-
<?php
class cs_music_player extends WP_Widget
{
function cs_music_player()
{
$widget_ops = array('classname' => 'cs_music_player', 'description' => 'Select artist to Play Your Playlist.' );
$this->WP_Widget('cs_music_player', 'ChimpS : MusicPlayList', $widget_ops);
}
function form($instance)
{
$instance = wp_parse_args( (array) $instance, array( 'title' => '' ) );
$title = $instance['title'];
$get_post_slug = isset( $instance['get_post_slug'] ) ? esc_attr( $instance['get_post_slug'] ) : '';
$numtrack = isset( $instance['numtrack'] ) ? esc_attr( $instance['numtrack'] ) : '';
?>
<p>
<label for="<?php echo $this->get_field_id('title'); ?>">
<span>Title: </span>
<input class="upcoming" id="<?php echo $this->get_field_id('title'); ?>" size="40" name="<?php echo $this->get_field_name('title'); ?>" type="text" value="<?php echo esc_attr($title); ?>" />
</label>
</p>
<br />
<p>
<label for="<?php echo $this->get_field_id('get_post_slug'); ?>">
<span>artist for Playlist:</span>
<br /><br />
<select name="<?php echo $this->get_field_name('get_post_slug'); ?>" style="width:225px;">
<?php
global $wpdb,$post;
$args = array( 'post_type' => 'artists', 'posts_per_page' => -1,'post_status'=> 'publish');
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
?>
<option <?php if($get_post_slug == $post->post_name){echo 'selected';}?> value="<?php echo $post->post_name;?>">
<?php echo substr(get_the_title(), 0, 20); if ( strlen(get_the_title()) > 20 ) echo "...";?>
</option>
<?php endwhile; ?>
</select>
</label>
</p>
<p>
<label for="<?php echo $this->get_field_id('noot'); ?>">
<span>No Of Tracks To Play: </span>
<input class="upcoming" id="<?php echo $this->get_field_id('numtrack'); ?>" size="2" name="<?php echo $this->get_field_name('numtrack'); ?>" type="text" value="<?php echo esc_attr($numtrack); ?>" />

Answer 1

the_widget accept three arguments:
$widget : the widget name, in your case cs_music_player
$instance : the widget instance settings. It's an array where your widget options goes. You can do something like this: array('title' => 'Your widget title', 'get_post_slug' => 'slug_of_your_artist', 'numtrack' => 10)
$args : an array of options used to display your widget. You can send an empty array to use the defaults, or just ignore that parameter.
In the end, your widget call will look like that:
global $post;
the_widget(
'cs_music_player',
array(
'title' => 'Your widget title',
'get_post_slug' => $post->post_name,
'numtrack' => 10
)
);
