If my blog is set up for only one post displayed at a time do I need "the loop"?

    Yes, yes, mark this question absurd, and showing my misunderstanding of the glorious \o/ //**LOOP**\\ \o/. All due respect and reverence aside, I’ve done my best to display only one post at a time. The visitor selects “older” or “newer post” to select the next in time either raw-time or, if a tag is being searched, the newer or older in that tag. A home link is also provided, always to allow navigation to the most recent post.

    Now. Let’s get to it. I have the familiar “if we have any posts, while there are any, loop through them one at a time…” structure. Followed by the usual “else display GO FISH”. Is there any reason I could not rewrite my template to, instead of looping, simply “if have posts, display a post (with appropriate next/prev links)”… [and eliminate the while loop]?

    I like simplicity.

  • This is possible, although I haven’t thoroughly tested it yet. You could use get_posts() to get the appropriate post information:

    <?php
$args = array(
   'category'       => 38,
   'posts_per_page' => 1,
);

$query = get_posts( $args );

echo '<h2>' . $query[0]->post_title . '</h2>';
echo '<p>' . $query[0]->post_content . '</p>';
?>

    This code gets one post from the category with the ID 38 and displays the post title wrapped in <h2> tags and the post content wrapped in <p> tags.

    I suppose, in the end, all I’m asking is, is the loop a necessary component, considering (as I understand it) that the query is already done upon page display in the head section? Is not post content, next- and prev- post link info available within appropriate PHP/Wordpress functions, without having to nest them within “the loop”?

    Not without a bit of coercing, because the_content() sets a bunch of filters on the content to make things like shortcodes work. But you could do this:

    <?php
echo '<h2>' . $post->post_title . '</h2>';

$content = $post->post_content;
$content = apply_filters( 'the_content', $content );
echo $content;

previous_post_link();
next_post_link();
?>

    for use in single.php or page.php, i.e. where you definitively expect one post and only one, you could replace the default loop structure:

    <?php
if ( have_posts() ) {
	while ( have_posts() ) {
		the_post();
		//
		// Post Content here
		//
	} // end while
} // end if
?>

    simplified with:

    <?php
		the_post();
		//
		// Post Content here
		//
?>

    not sure what the advantage of this would be if any.
