Wordpress query posts change category with ACF

Question 1

Dude, You can do lot of things for that. If I am in your seat i will do like this.

Here is the code. In this I used category slug you can use the id also.

In your function.php file add this

/*------------------------------------------*/
/**  [media] shortcode function - by Yesh  **/
/*------------------------------------------*/
function mediaShortcode($atts) {
  //Extract Shotcode from the pages and posts
  extract(shortcode_atts(array('slug' => 'default'), $atts));
  global $post;
  $args = array( 'numberposts' => 5, 'category_name' => $atts['slug'], 'orderby'  => 'post_date', 'order' => 'DESC');
  //print_r($args);
  $posts = get_posts( $args );
  //print_r($posts);
  $html="";
  foreach ($posts as $post) {
    $html.='<article class="left-container-video">';
      $html.='<header class="video-header">';
        $html.='<a href="'.$post->guid.'"><h1>'.$post->post_title.'<h1></a>';
      $html.='</header>';
      $html.='<div class="video-container">';
        $html.=$post->post_content;
      $html.='</div><!-- end vid container -->';
    $html.='</article>';
    //$html.=do_shortcode($post->post_content);
  }
return $html;
}
add_shortcode('media', 'mediaShortcode');

in your template.php

<?php
/*
Template Name: Media page Template
*/
?>
<?php get_header(); ?>
<div class="wrapper-small">
    <div style="" id="media-page">
    <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
        <?php the_content(); ?>
    <?php endwhile; ?>
        <!-- <div class="navigation">
            <div class="next-posts"><?php next_posts_link(); ?></div>
            <div class="prev-posts"><?php previous_posts_link(); ?></div>
        </div> -->
    <?php else : ?>
        <h1>Not Found</h1>
    <?php endif; ?>
  </div>
</div><!-- end wrapper -->
<?php get_footer(); ?>

and now, as my function. I have to add in the page [media slug="video-category"]. Select page template as Media Page template. Thenpublish. If you want to show more category posts. Just add after the first line your next category slug.[media slug="video-gallery]`.

This will show the rest of posts in your gallery. You have to select the theme only. You can use this in any page.

Question 2

You can simply include a PHP file in each of your custom templates:

partial-include.php:

<?php query_posts("cat=" . $category_id); // category is not hardcoded ?>
    <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
    <article class="left-container-video"<?php post_class() ?> id="post-<?php the_ID(); ?>">
        <header class="video-header">
            <a href="<?php the_permalink() ?>"><h3> <?php the_title(); ?> </h3></a>
        </header>
        <div class="video-container">
            <iframe src="<?php the_field("link"); ?>" frameborder="0" width="560" height="315"  allowfullscreen></iframe>
        </div><!-- end vid container -->
    </article>
    <?php endwhile; ?>
<?php else : ?>
    <h2>Sidan hittades inte</h2>
<?php endif; ?>
<?php wp_reset_query(); ?>

Then in each of your template files:

custom-template-1.php:

<?php
/*
Template Name: Custom Page 1
*/
get_header();
?>

    // ....

    <?php
        $category_id = 123;
        include('partial-include.php');
    ?>

    // ....

<?php get_footer(); ?>

You can repeat this for each of the pages that need the functionality.

If you need to integrate this with custom fields from Advanced Custom Fields, you can change the value of $category_id by doing the following in your custom-template-1.php file:

<?php
    $category_id = get_field('category_id'); // example
    include('partial-include.php');
?>
