Push metadata in array

Question

Applying meta keys in search result

Since I need to take on a different approach to get my data in javascript from wordpress, I am trying to apply (as follow up on my post earlier today (https://stackoverflow.com/questions/34873986/javascript-for-each-custom-post-type-wordpress)) metadata to my query so it will spit out the right information. This is practically harder than I thought, cause I preferly want it in one query. I been googling now for quite a while, cause I had hoped I wasn't the only one with this problem. I cant seem to find a relevant answer to my problem

Case

Since I was being pointed to the fact javascript and php dont play nice, I was beginning to explore a different way. It requires me to get the results on forehand before I push this into javascript via a json_encode. So far this is running fine, except for one tiny thing. When asking in WP_query I cant get any meta data, which is the part I really need, since that contain map information for my google maps. So is there a way I can query that before I push this through?

<?php
$args = array(
        'post_type' => 'hotels',
 );

$query = new WP_Query( $args );
echo '<pre>';
print_r($query->posts);
echo '</pre>'
?>

<script type="text/javascript">
var post_info = <?php echo json_encode($query->posts); ?>;
<script>

So far I managed to check what is been given, but I sume, I cant get this via wp_query. Is there another way to actually get the data I need? Or is there a way I can push the meta data in the array with each single post, so I can acces it in Javascript?

Answer 1

You need to loop through your posts, and retrieve the metadata for each post. Add them to your array, and encode them to JSON.

$posts = $query->get_posts();
foreach( $posts as &$thispost ) { // reference the current item

    $thispost->meta = get_post_meta( $thispost->ID );

}

Now you got a WP_Post-Object, with all the post meta available at $post->meta['meta_key'][0]. If more than one value is saved for a meta key, you can loop through the ['meta_key']-Array.
