How can I include user_submit_name value in the post

This must only show up, when post is submitted by regular user or unregistered user.

You could do this by editing the theme template. For example, here is one way to do it via functions.php:

// USP prefix submitted content
function my_the_content_filter($content) {
	global $post;
	$usp_author = get_post_meta($post->ID, 'user_submit_name', true);
	if (usp_is_public_submission()) {
		$content = $usp_author . ' writes: ' . $content;
	}
	return $content;
}
add_filter('the_content', 'my_the_content_filter');

Thank you.

Thank you but we still have a small problem.
This works fine in front page but not in single post view.

This is “not resolved”. Please do not mark this as resolved.

Could be an issue with whatever theme you are using.. the code just works by filtering the content wherever it is displayed using the_content().

Apologies for marking the thread as “resolved”, it seemed pretty resolved to me.

Let me know if any further questions or confusion, glad to help.

I hope I am not wasting you time. I am not a programmer so it’s possible I am talking rubbish. ??

I searched and searched a bit more and it sounds to me that the_content returns content with a line-brake in front of it unless a filter is used.
Filter you posted, works nice in front page but not in single post view.

This is how my content.php looks like (post page)

<?php if ( is_singular() ) { ?>

		<header class="entry-header">
			<?php echo apply_atomic_shortcode( 'entry_title', '[entry-title]' ); ?>
			<?php echo apply_atomic_shortcode( 'byline', '<div class="byline">' . __( 'Published by [entry-author] on [entry-published] [entry-comments-link before=" | "] [entry-edit-link before=" | "]', 'path' ) . '</div>' ); ?>
		</header><!-- .entry-header -->

		<div class="entry-content">
 			<?php  the_content(); ?>
....

And it return:
BlaaBlaa writes: (paragraph tag p line brake)
What ever he/she wrote blaa blaa blaa…

same time, on the front page, where only excerpt is returned, I get

BlaaBlaa writes: What ever he/she wrote blaa blaa blaa…

Do you see the difference.
One has a line brake after the “user name writes:”

Thanks stuudio!
