Wordpress: Hide title if there is less then one post...??

This seems like a dumb question but I can't seem to figure it out.

I have created a query post that will list the last 5 posts based on some custom fields data. However, its a new site so it might be a little bit before any posts show up in the list. Above the query post, I have added a title (i.e. "Latest Posts") but want the title to not appear if there are no posts in the list. Obviously, if I put it within the while loop that generates the list, it will get repeated each time.

So how do I remove my title from outside the loop if there is less then one post in the list? Again, it seems like a real simple concept but I think my brain is a little fried at the moment and I can't quite figure it out.

You could put in a variable that changes within the the loop based on whether your query returns rows. Then outside the loop, do the comparison. I am not sure which database type you are using, but in MS SQL it would be something along this line:

declare @count int
set @count = 0

While <condition exists>
begin
<your code here>
set @count = @count + @@ROWCOUNT
end

If @count < 1
begin
<hide title>
else
<display title>

I am not as familiar with MySQL, but here is a reference for the functions.

Make sure that you set the @count variable directly after the select statement that returns your rows. The @@ROWCOUNT counts the number of rows in the previous SQL statement and if it isn't a select statement, it will not work as expected.

This is covered in "Other Loop Tricks" in the Codex:

http://codex.wordpress.org/The_Loop_in_Action#Other_Loop_Tricks

<?php if (have_posts()) : ?>

  <?php if (($wp_query->post_count) > 1) : ?>
     <?php while (have_posts()) : the_post(); ?>
       <!-- Do your post header stuff here for excerpts-->
          <?php the_excerpt() ?>
       <!-- Do your post footer stuff here for excerpts-->
     <?php endwhile; ?>

  <?php else : ?>

     <?php while (have_posts()) : the_post(); ?>
       <!-- Do your post header stuff here for single post-->
          <?php the_content() ?>
       <!-- Do your post footer stuff here for single post-->
     <?php endwhile; ?>

  <?php endif; ?>

<?php else : ?>
     <!-- Stuff to do if there are no posts-->

<?php endif; ?>

Open in new window


So you can see from the above that first you check for if have_posts() and then open the loop.  Put the text outside of the while statement and it will only repeat once.  If you don't have any posts, that's where the else comes in.  In your case, do nothing.



<?php if (have_posts()) : ?>

  <?php if (($wp_query->post_count) > 1) : ?>
     <?php while (have_posts()) : the_post(); ?>
       <!-- Do your post header stuff here for excerpts-->
          <?php the_excerpt() ?>
       <!-- Do your post footer stuff here for excerpts-->
     <?php endwhile; ?>

  <?php else : ?>

     <?php while (have_posts()) : the_post(); ?>
       <!-- Do your post header stuff here for single post-->
          <?php the_content() ?>
       <!-- Do your post footer stuff here for single post-->
     <?php endwhile; ?>

  <?php endif; ?>

<?php else : ?>
     <!-- Stuff to do if there are no posts-->

<?php endif; ?>

Open in new window

And I have no idea why the snippet doubled up, but enjoy it.
