add_meta_box based on custom posts

    Hi all,

    I have 2 custom posts: “staff” and “projects”. I would like to have a custom data field that lists all available staff with checkboxes next to the name, so a one or more staff members could be associated to a project.

    I’m close, but the loop that lists my staff members is messing things, and I don’t know how to reset the loop back. I’ve tried a bunch of things, but none seem to do it.

    With the code I have, the projects page starts to list staff (only one staff), and my project disappears… the project pages list staff. If I delete my code. Everything comes back to normal.

    Here’s my code in functions.php:

    add_action("admin_init", "admin_init");
function admin_init(){
	add_meta_box("credits_meta", "Design & Build Credits", "credits_meta", "projects", "side", "low");
}

function credits_meta() {
  global $post;
  $custom = get_post_custom($post->ID);
  $designers = $custom["designers"];

  ?>
  <p><label>Designed By:</label><br />

  <?php 

  $my_query = new WP_Query('post_type=staff');
  if ($my_query->have_posts()) {
	while ($my_query->have_posts()) : $my_query->the_post(); $do_not_duplicate = $post->ID;
	$checked = '';
	if(count($designers) > 0) {
		foreach ($designers as $d)
			if ($d == the_title('', '', false)) $checked ='checked = checked';
	}
	?>
        <input type="checkbox" name="designers[]" value="<?php the_title(); ?>" <?php echo $checked; ?>><?php the_title(); ?><br />

	<?php endwhile; } 

	?>

  <?php
  wp_reset_query();
}

add_action('save_post', 'save_details');
function save_details(){
  global $post;

  if ($_POST["designers"]) {
  	foreach ($_POST["designers"] as $x) add_post_meta($post->ID, "designers", $x, false);
  }
}

    To create this code, I used https://carsonified.com/blog/dev/create-your-first-wordpress-custom-post-type/ as a base.

    Thanks

    Figured it out.

    I used a custom query, instead of the loop:

    add_action("admin_init", "admin_init");

function admin_init(){

  add_meta_box("credits_meta", "Credits", "credits_meta", "projects", "side", "low");
} 

function credits_meta() {
  global $post;
  global $wpdb;
  $custom = get_post_custom($post->ID);
  $designers = $custom["designers"];

  ?>

  <?php
   $querystr = "
    SELECT wposts.*
    FROM $wpdb->posts wposts
    WHERE wposts.post_type = 'staff'
    AND wposts.post_title != 'Auto Draft'
    ORDER BY wposts.post_name DESC
 ";

 $my_query = $wpdb->get_results($querystr, OBJECT);

 if( $my_query ) {

  foreach( $my_query as $s ) {

	$checked = '';
	if(count($designers) > 0) {
		foreach ($designers as $d)
			if ($d == $s->ID) $checked ='checked = checked';
	}
	?>

    <p><input type="checkbox" name="designers[]" value="<?php echo $s->ID ?>" <?php echo $checked; ?>> <?php echo $s->post_title; ?></p>

	<?php
  }

 }

}

add_action('save_post', 'save_details');
function save_details(){
  global $post;

  delete_post_meta($post->ID, 'designers');
  if ($_POST["designers"]) {
  	foreach ($_POST["designers"] as $x) add_post_meta($post->ID, "designers", $x, false);
  }

}

    Did you work out how to output your custom data into a page template?
