Instead of using
query_posts why don't you use a
WP_Query? This will get you an array that you can query the size of, then you could then have a counter which increments and once it hits the halfway mark, you insert whatever you want and move on.
Set it up like this:
// first, run the main loop to get the text editor content
while(have_posts()) : the_post();
// we just assign it to a variable at this point without printing it
$content_to_insert = get_the_content();
// now we set up the query to get out all the party posts
$parties_query = array(
'cat' => 10,
'tag' => 'parties',
'orderby' => 'rand',
'posts_per_page' => -1
// NB. you will not get ALL your results unless you use 'posts_per_page' or 'showposts' set to -1
// Now run a new WP_Query with that query
$parties = new WP_Query($parties_query);
// get the halfway point - needs to be a whole number of course!
$half = round( sizeof($parties)/2 );
// this is our counter, initially zero
$i = 0
while($parties->have_posts()) : $parties->the_post(); ?>
<?php if ($i == $half) : ?>
// we are halfway through - print the text!
<?php echo apply_filters('the_content', $content_to_insert); ?>
<?php else : ?>
// render your party stuff
// you can use tags reserved for use in the loop, eg.
<h2><?php the_title(); ?></h2>
<?php endif; ?>
<?php $i++; endwhile; ?>
Hope that works. It was a late old night of Christmas parties last night.
