Display post list by custom post type and category

Question

Hi i need to display list of post by post type and category, i have code like this, but it isint working properly:

<?php $catquery = new WP_Query( 'posts_per_page=999&post_type=posttypename&cat=categoryname' ); while($catquery->have_posts()) : $catquery->the_post(); $i = 1; ?>

This code displaying post from "posttypename", but it displays all post from that custom post type, but i need to displaying post from only "categoryname"

The whole code looks like this:

 <?php $catquery = new WP_Query( 'posts_per_page=999&post_type=posttypename%cat=categoryname' ); while($catquery->have_posts()) : $catquery->the_post(); $i = 1; ?> <?php if($i == 1) : ?> <div class="">content of the post</div> <?php endif; ?> <?php $i++; endwhile; ?>

Answer 1

Use WP_Query like this :

$catquery = new WP_Query(array(
    'post_type'      => 'posttypename',
    'posts_per_page' => -1,
    'category_name'  => 'categoryname',
    // 'cat'         => cat ID here
));
if( $catquery->have_posts() ){
    while($catquery->have_posts()){
        $catquery->the_post();
        // your stuff
    }
    wp_reset_postdata();
}

));
if( $catquery->have_posts() ){
    $i = 1; 
    while($catquery->have_posts()){
        if($i == 1){ ?>
            <div class="">content of the post</div>
