Multiple post type queries (with specific arguments for each)

Question

So i know how to combine post types into 1 loop and out put the loop. Below is what i have:

        <?php

        $args = array(
            'post_type' => array('post','movie','actor'),
            'posts_per_page' => '20',
        );

        query_posts( $args );
        while ( have_posts() ) : the_post(); 

            the_title();

        endwhile; 

        ?> 

This works as expected, however is it possible to specify different arguments for each post type, while keeping them within the same original loop.

So for example i need to add a meta_key=value argument to the movie & actor post types. Is this possible?

Answer 1

Could you do something like this?

<?php

    $args = array(
        'post_type' => array('post','movie','actor'),
        'posts_per_page' => '20',
    );

    query_posts( $args );
    while ( have_posts() ) : the_post(); 

        global $post;

        if (($post_type == 'movie') && (get_post_meta($post->ID, 'meta_key', true) == 'your-value')) {

             // Display your content for Movie Post Type with meta value set

         } else if (($post_type == 'actor') && (get_post_meta($post->ID, 'meta_key', true) == 'your-other-value')) {     

             // Display your content for Actor Post Type and Other Meta Value

         }    

    endwhile; 

    ?>
