Always the same post of a custom post type is shown on a single page

    Hi i ran into an odd problem. I am running WordPress 3.8 and the relevant plugins are advanced custom fields (including the repeater field add on) and custom post types ui. I’ve created a custom field for projects and display them in a custom post type.

    The custom field consists of:

    1) title
    2) Project summary picture (fieldname: pro_preview, field type: image)
    3)Project description (fieldname: pro_description, field type: text area)
    4) project services (fieldname: pro_services field type: repeater)
    4.1) service (fieldnamen: pro_service_single field type: text)
    5.) project images (fieldname: pro_images, field type: repeater)
    5.1.) image (fieldname: pro_impressions, field type: image)

    I have an overview page (template-projects.php) which lists all projects properly. If i mouse over one of the projects (e.g. running) the href shows localhost:8888/testsite/projects/running, or localhost:8888/testsite/projects/bike if i mouse over e.g. the bike project. but no matter which project i choose each time only one certain single other project is shown. no running no bike just lets name it nutrition. but i have no idea why. my single page is called single-projects.php . and also the adressbar is showing the correct adress like e.g. localhost:8888/testsite/projects/running in the case i’ve clicked running – but the content shows nutrition.

    The query part on the single-projects.php page looks like that. For testing purpose i’ve only queried the title, description and services.

    <?php
		$args = array(
			'post_type' => 'projects',
			'posts_per_page' => 1
		);
		$the_query = new WP_Query( $args );
	?>
	<? if ( have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
		<h3><?php the_title(); ?></h3>
		<p><?php the_field( 'pro_description' ); ?></p>
		<h4>Our services</h4>
		<?php if(get_field( 'pro_services' ) ): ?>
				<ul>
				<?php while( has_sub_field( 'pro_services' ) ): ?>
					<li><?php the_sub_field( 'pro_service_single' ); ?></li>
				<?php endwhile; ?>
				</ul>
		<?php endif; ?>
	<?php endwhile; ?>
		<?php wp_reset_postdata(); ?>
	<?php else: ?>
		<p>Something is gone wrong...</p>
	<?php endif; ?>

    I am out of ideas what is going wrong here. :/ any hints are appreciated. best regards ralf

    Every time, you are seeing the most recent post from the projects post type. This is because you have created a new query with WP_Query which instructs WordPress to do exactly this.

    What you actually want to do is simply rely on the main query, along the lines of:

    <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<!-- Stuff -->
<?php endwhile; endif; ?>

    When the file name is single-[name of the post type].php, WordPress will do the rest for you.

    Coooool fixed the issue. But one thing drove me nuts, is it possible that WordPress has its issues with commented out lines of code?

    commented out the first part 

    <!--
			<?php
			$args = array(
				'post_type' => 'projects',
				'posts_per_page' => 1
			);
			$the_query = new WP_Query( $args );
		?>
		<? if ( have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
-->

    and replaced it with: 

    <? if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

    and i got “PHP Parse error: syntax error, unexpected end of file” always on the end of my template file on the get_footer call. if i deleted the commented out parts it worked. strange. but thanks for the explanation about the loop thing – understand it now . thanks!
