Changing the button type to button, opens an additional field called Click Target, there is note which says: Selector or callback function to push form values on click.

What is the selector or callback function so that the button redirects to a url?
Have tried using just a url, but the button isn’t working?

For example, I want to build a select list of posts that were published in 2017 by user XXX.

I know how to query what I want, but how do I dynamically add the query as the options value:

These options are static:

‘type’ => ‘select’,
‘options’ => array(
‘java’ => ‘Java’,
‘javascript’ => ‘JavaScript’,
),

… but I need to create them dynamically … for example

‘type’ => ‘select’,
‘options’ => ‘name_of_callback_function,
),

… or …

‘type’ => ‘select’,
‘callback’ => ‘name_of_callback_function,
),

add_filter('the_content', 'my_fun');

and

function my_fun($content){
print_r($content); // Returns blank ???
}

Should $content be blank? Doesn’t it suppose to return data like get_page( $page_id );

I’d like to use the Callback Function type for a couple of fields on the form. One to display the states in a dropdown and another to show multiple checkbox.

How should I create the filter/function to achieve this?

Thanks in advance,

I used a callback function for the wp_list_comments so that might be the case. The code is

function erubai_comments( $comment, $args, $depth ) {
	$GLOBALS['comment'] = $comment;
	?>
		<?php if ( $comment->comment_approved == '1' ): ?>
		<li class="post-comment">
			<article id="comment-<?php comment_ID() ?>" class="group">
				<div class="vcard grid-1-5">
					<?php echo get_avatar( $comment, 128 ); ?>
				</div>
				<div class="comment-content grid-4-5">
					<h4 class="fn">
						<?php comment_author_link() ?>
					</h4>
					<time>
						<a href="#comment-<?php comment_ID() ?>" pubdate>
							<?php comment_date() ?> at <?php comment_time() ?>
						</a>
					</time>

					<?php comment_text(); ?>
					<p><?php comment_reply_link(array_merge( $args, array('depth' => $depth, 'max_depth' => $args['max_depth']))); ?></p>
				</div>
			</article>
		<?php endif;
	}

What might be the problem?

Thanks in advance!!

Any help here will be appreciated.
