[edit] TLDR: The answer: don't use <code>echo</code>, but <code>print_r</code> I have tried the following to get the meta value as a string, instead of an Array. The third value is set to true, so this should result as a string. <pre><code><?php // The data $projects = $wpdb->get_results( "SELECT * FROM $wpdb->posts" ); // Loop them foreach ( $projects as $project ) { // Get the meta $metas = get_post_meta( $project->ID,'bc_invited', true ); // This is rendering echo '<h2>' . $project->post_title . '</h2>'; foreach($metas as $meta){ // This is not rendering echo $meta . ' '; } } ?> </code></pre> Why am I not seeing what I expected?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
