如何使用特定类别发布帖子

Question

I'm just getting back into Wordpress and php after a few years away. I'm pretty ignorant when it comes to php syntax so making lots of mistakes.

I need to display a single post on a page, it's title and contents, and it needs to be specific to a category that I've created.

I grabbed this of the web and tried to change it, but I can't get it to work.

<?php query_posts('category_name=qaadrant&showposts=1');
    while (have_posts()) : the_post();
      // do whatever you want
    ?>
    <h2><a href="<?php the_permalink() ?>" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2>

    <p><a href="<?php the_permalink() ?>" title="Permanent Link to <?php the_content(); ?>"><?php the_content(); ?></a></p>

Any help much appreciate. Niall

Please use awesome WP_QUERY Class see the reference here: https://codex.wordpress.org/Class_Reference/WP_Query Using following code to get posts from category you selected. No-paging is set to make query faster:

    <?php
$args = array(
    'post_type' => 'post',
    'posts_per_page' => 1,
    'category_name' => 'qaadrant',
    'no-paging' => true,    
);
$the_query = new WP_Query( $args ); 
if ( $the_query->have_posts() ) : 
while ( $the_query->have_posts() ) : $the_query->the_post(); ?>

    <h3><?php echo get_the_title(); ?></h3>
        <p><?php echo get_the_excerpt(); ?></p>


    <?php endwhile; ?>
    <?php wp_reset_postdata(); ?>
