Make a select list of a custom post type in a meta box

Question

Simple you will say?

I have a first Custom post type called Country. I have a second Custom post type called Travellers. I need to make a drop down select list (multiple check) available when editing Countrywith content from Travellers. This will allow me to select travellers for each country.

Help!

thx in advance

Answer 1

very simeler to the question here Display list of tags as drop down menu or radio buttons in a meta box?

but instead of list of tags you need to query the post list of your travellers post type something like this:

$travelers = new WP_Query();
$travelers ->query('post_type=travelers&postprepage=-1');
while ($travelers->have_posts()) : 
   $recentPosts->the_post();
   $travellersnames[] = $post->title;
endwhile

and show the $travellersnames as your option for a select filed or multi select filed in your meta box

Answer 2

I am trying to accomplish this same thing, but the code here is not working for me... is the syntax all correct? I have a basic working knowledge of PHP, but I can't tell what's going on here.

Perhaps some clarification?

Thanks in advance!

Answer 3

Following the answer I ended up with

$s_query = new WP_Query( array(
    'suppress_filters' => false,
    'post_type' => 'slide'));
while($s_query->have_posts()):$s_query->the_post();

    $sname = $post->post_title;
    $s_output2 ='';
    $s_output2 .= '<option value="'.$post->ID.'" >';
    $s_output2 .= $post->post_title;
    $s_output2 .= '</option>';
    echo $s_output2;

endwhile ;
wp_reset_query();
