First post of each category

2 Views

I’m trying to create a simple loop, that gets the latest post of 3 selected categories. I’ve searched for something similar to learn from, but most are overly complex.

At the moment, I have:

    <?php 

    // WP_Query arguments
$args = array (
    'category_name'          => array('lifestyle', 'fashion', 'beauty')
);

// The Query
$query = new WP_Query( $args[0] );

// The Loop
if ( $query->have_posts() ) {
    while ( $query->have_posts() ) {
        $query->the_post();
        // do something
    }
} else {
    // no posts found
}

// Restore original Post Data
wp_reset_postdata();

?>

I assume I’d need a foreach loop, but I’m unsure how to implement it in this scenario, and for just the latest of each post?

Any help would be great.

  1. It’s not possible to get one posts per category with one simple query, and even a complex query will take more time than 3 separate query. So, if you want simplest, then this is the solution – 

    $cats = array('lifestyle', 'fashion', 'beauty');
$exclude_posts = array();
foreach( $cats as $cat )
{
    // build query argument
    $query_args = array(
        'category_name' => $cat,
        'showposts' => 1,
        'post_type' => 'post',
        'post_status' => 'publish',
        'orderby' => 'date',
        'order' => 'DESC'
    );

    // exclude post that already have been fetched
    // this would be useful if multiple category is assigned for same post
    if( !empty($exclude_posts) )
        $query_args['post__not_in'] = $exclude_posts;

    // do query
    $query = new WP_Query( $query_args );

    // check if query have any post
    if ( $query->have_posts() ) {

        // start loop
        while ( $query->have_posts() ) {
            // set post global
            $query->the_post();

            // add current post id to exclusion array
            $exclude_posts[] = get_the_ID();


            // do something
        }
    } else {
        // no posts found
    }

    // Restore original Post Data
    wp_reset_postdata();
}
