using if statement to load different “the loop”

    I have three pages that display three different categories.
    1. our products
    2. where to buy
    3. press

    When each page loads I want to show the category that relates to the page. In each case the way I layout the image and title is different. I thought I would use an if statement to see what page was loaded and then load the appropriate loop using an include.

    This works great from the home blog page (aka products page) but not from the press page?? The include loads but after the second if statement it fails. Why?

    The index page:

    <div id="mainContent">
	<!-- *note: home a.k.a. the blog page has been changed to the product page using the word press administrator but it is still refered to as home in the scripting-->

	<?php
// generate info appropriate to the page being displayed
if (is_home()) {
	 include( TEMPLATEPATH . '/theLoop_poducts.php' );
	include( TEMPLATEPATH . '/theLoop_where_to_buy.php' );
	include( TEMPLATEPATH . '/theLoop_press.php' );
 <!-- this works like a charm -->

} elseif (is_page()) {
        // we're looking at a static page.  Which one?
        if (is_page('in-the-press')) {
             // our press page.
 		echo "<p>This is in the press!</p>";
		include( TEMPLATEPATH . '/theLoop_press.php' );

        } else {
              // catch-all for other pages
			  include( TEMPLATEPATH . '/theLoop.php' );
        }
} else {
        // catch-all for everything else (archives, searches, 404s, etc)
        echo "<p>Pedro offers you his protection.</p>";
		 include( TEMPLATEPATH . '/theLoop.php' );
}
?>

</div><!--end of mainContent-->

    The include page:

    <!-- the loop
if category is "product" then display
else say sorry no post vailable
-->

Product page has loaded
			 <!-- Start the Loop. -->
 <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

		<!-- The following tests if the current post is in category Products. -->
		<!-- If it is, the div box is given the CSS class "products". -->

		<?php if ( in_category('products') ) { ?>
				<div class="product">
				<!-- Display the Title as a link to the Post's permalink. -->
				<a href="<?php the_permalink(); ?>">
				<div id="title"><?php the_title(); ?></div>

				<!-- Display the Post's Content in a div box. -->
				<div class="entry"><?php the_content(); ?></div>
				</a>

				</div> <!-- closes the first div box -->

		<?php } ?>

		 <!-- Stop The Loop (but note the "else:" - see next line). -->
		 <?php endwhile; else: ?>

		 <!-- The very first "if" tested to see if there were any Posts to -->
		 <!-- display.  This "else" part tells what do if there weren't any. -->
		 <p>Sorry, no products available.</p>

<!-- REALLY stop The Loop. -->
<?php endif; ?>

    Thanks I’ve tried that but the problem remains the same:

    The first if ( do you have post = yes) works.

    The second fails, but only in the template. ( if post category is “press” …display title etc.) 

    <?php if (in_category('press') ) {
		  echo "<p>category is press</p>";
				the_title(); 

		 } else {
		 echo "<p>no category found</p>";
		 } ?>

    Does the template launch from a different location than the root? Should the category be ../press or something weird like that? —?Stumped.

    The value in in_category’s parentheses is either a category’s ID, slug, or name. It has nothing to do with disk locations at all.

    I am still unclear on what your problem is.

    You might want to restructure your if’s – you don’t need nested If’s

    if (is_home()) {
 ....
} elseif is_page('in-the-press') {
 ...
} elseif is_page() {
 ...
} else {
 ...
}

    I’ve got it!

    you have to query the post before the loop not inside it as I have done.

    Place a call to query_posts() in one of your Template files before The Loop begins. The wp_query object will generate a new SQL query using your parameters. When you do this, WordPress ignores the other parameters it receives via the URL (such as page number or category). If you want to preserve that information, you can use the $query_string global variable in the call to query_posts().
    …more on query_posts

    So, the principal remains the same. Index file checks to see what page we are on. If the page is static and the page name is “press” then include file “theLoop_press” which loads only posts that are tagged with the “PRESS” tag.

    The fixed code for the new and included loop is:

    this is the press loop
<?php
query_posts('category_name=press');

global $more;
// set $more to 0 in order to only get the first part of the post
$more = 0; 

// the Loop
while (have_posts()) : the_post();
?>

				<div class="press">
				<!-- Display the Title as a link to the Post's permalink. -->
						<a href="<?php the_permalink(); ?>">permalink</a>
						<div id="title"><?php the_title(); ?></div>

				<!-- Display the Post's Content in a div box. -->
						<div class="entry">
						<!-- the content of the post -->
						<?php the_content('view full the article?'); ?>
						</div>
				</div> <!-- closes the first div box -->

<?php
endwhile;
?>

    *Note for those who are interested in using an “if” statement Vs. Templates :

    After educating myself I have found that my “if” statement serves the same purpose as WP’s templates. The idea being “If page loading is X; use this layout.” The advantage of using a template is that your client can change or apply the new layout on their own without having to call you to change the if statement.

    EG:
    1. “Portfolio page” has the same layout as “My photos page”.
    2. Pre-christmas layout Vs Boxing day sales Vs regular season layout. (this could be a change in the whole layout or just the header. No more calls from the client asking for trivial changes)
