Query question

This is how you get the title:
<?php echo get_the_title($ID); ?>

This is how you show get the title to show up:
<?php wp_title(); ?>

This is how you get the permalink :
<?php $permalink = get_permalink( $id ); ?>

And this is how you get the permalink to show up:
<?php the_permalink(); ?>

Thank you for your response, but I understand that part.

I need to get one <h1><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h1> of a specific category if there is a post in that category. If not, I get nothing.

assuming the specific category id is 73:

<?php $cat_post = new WP_Query( array( 'posts_per_page' => 1, 'category__in' => array(73) ) );
if( $cat_post->have_posts() ) : while( $cat_post->have_posts() ) : $cat_post->the_post(); ?>
  <h1><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h1>
<?php endwhile; endif; wp_reset_postdata(); ?>

or alternatively you could use get_posts() with the same arguments;

<?php $cat_post = get_posts( array( 'posts_per_page' => 1, 'category__in' => array(73) ) );
if( $cat_post ) :
foreach( $cat_post as $post ) {
  setup_postdata($post); ?>
  <h1><a href="<?php echo the_permalink(); ?>"><?php the_title(); ?></a></h1>
  <?php }
endif; wp_reset_postdata(); ?>

Thank you very much alchymyth. I will give that a try.

For some reason my custom post type is not showing up. I am guessing I need to put post_type in an array?

Here is what I got and I keep getting a syntax error. What am I missing.

` $cat_post = new WP_Query(array(
‘post_type’ => array(
‘post’,
‘custom1’,
‘custom2’,
),
‘showposts’ => ‘1’),
‘category__in’ => array(2)
);`

round 2, still same issue.

$cat_post = new WP_Query( array(
	'posts_per_page' => 1,
	'category__in' => array(2))
	'post_type' => array(
	'post',
	'custom1',
	'custom2',
	),
	);

For future reference.

$cat_post = new WP_Query( array(
	'posts_per_page' => 1,
	'category__in' => array(2),
	'post_type' => array(
	'post',
	'custom1',
	'custom2',
	)
	));
