Need to access post using slug

Code like this will do it.

<?php
$my_query = new WP_Query('name=my-post-slug');
while ($my_query->have_posts()) {
$my_query->the_post();
the_title(); // whatever you want to display the post here
the_content(); // just like a normal Loop
}
?>

That works great!

I am using this to create a specif intro texts for each category and subcategory.

I give the intro text post for a category or subcategory a slug name composed of the section number followed by “intro”, so for category 13 the slug for the intro post would be “13intro”

(btw, I am editing editing category.php)

With my additions the code looks like this

<?php
$postSlug = $this_category->cat_ID.”intro”;
$postSlug = “name=”.$postSlug;
$my_query = new WP_Query($postSlug);
while ($my_query->have_posts()) {
$my_query->the_post();
// the_title(); // whatever you want to display the post here
the_content(); // just like a normal Loop
}
?>

How can I modify this text to get the post slugs in the loop, to use it in my code?
