Stored quiz could be unpublished by default (optionally)

Hi

I did some quick fixes for this for 4.x.

Here are my steps.

1. set quiz content type that it is created unpublisehd by default. (content type workflow settings)
2. Use Publish content module for setting that authenticated users (or any you wanted roles) can set Published/Unpublished for their quizes. It will create Publish/Unpublish tabs on Quiz node.
3. edit node.tpl and add this code (for full node, not for teaser ):

<?php if ($unpublished) { ?>
    <div class="unpublished"><?php print t('Unpublished'); ?></div>
    <?php 
		if ($node->type == 'quiz') {
			if ( $user->uid == $node->uid) {
				if ( $node->number_of_questions == 0) {			
					print '<div style="font-size: 140%; line-height: 110%; border: 1px solid blue; color: navy; margin-top: 80px; padding: 9px; ">This quiz is marked as Unpublished, and it doesn't contains any questions. Questions for this quiz you can create and add after click on tab Manage questions. <br /><br />When your quiz will be prepared and you will be want to publish it for the others, click on the tab Publish..</div>';
				} else {
					print '<div style="font-size: 140%; line-height: 110%; border: 1px solid blue; color: navy; margin-top: 80px; padding: 9px; ">This quiz is marked as Unpublished, and it is waiting when you publish it. <br /><br />When you will be have all questions you want in this quiz, and you will be want to publish this quiz, click on the tab Publish.</div>';
				}
			}
		}
		
		} else {
			if ( $node->type == 'quiz' ) {
				if ( $node->number_of_questions == 0) {
					if ( $user->uid == $node->uid) {
					?>
					<div style="font-size: 140%; border: 2px solid red; color: maroon; padding: 9px; line-height: 110%; background: yellow;">This quiz doesn't contains any questions <strong>but it is marked as Published</strong>. Click on tab Unpublish and you do it invisible for others, until you add some appropriate questions. After then you can publish it.</div>
					<?php
					}
				}
			}
		}
		?>

That's all, quizes on your site will be from now published only when they will be complete, not more empty quizes, and quiz creators will be notified about publish/unpublish options.

Btw sorry for my english in the code above, I have it in Slovak language for my needs.

Have a nice day
