Support » Fixing WordPress » Overview page in backend does not show column values

  • I’m trying to make the overview page for my custom page type, but I can not get WP to display the custom field values, even though it’s possible to print the column headings.
    I have defined the custom fields in the functions.php and in the individual pages they are also displayed correctly:

     function cpt_workshop_meta_boxen(){
    	add_meta_box("art-meta", "Workshopart","cpt_workshop_feld_art", "workshopseite","normal","default");
    	add_meta_box("datum-meta", "Datum","cpt_workshop_feld_datum", "workshopseite","normal","default");
    	add_meta_box("ort-meta", "Ort","cpt_workshop_feld_ort", "workshopseite","normal","default");
    	add_meta_box("leitung-meta", "Leitung","cpt_workshop_feld_leitung", "workshopseite","normal","default");
     function cpt_workshop_feld_art(){
    	global $post;
    	$custom = get_post_custom($post->ID);
    	$art = $custom["art"][0];
    	echo '<input name="art" value="' . $art . '" />';
      function cpt_workshop_feld_datum(){
    	global $post;
    	$custom = get_post_custom($post->ID);
    	$datum = $custom["datum"][0];
    	echo '<input name="datum" value="' . $datum . '" />';
      function cpt_workshop_feld_ort(){
    	global $post;
    	$custom = get_post_custom($post->ID);
    	$ort = $custom["ort"][0];
    	echo '<input name="ort" value="' . $ort . '" />';
       function cpt_workshop_feld_leitung(){
    	global $post;
    	$custom = get_post_custom($post->ID);
    	$leitung = $custom["leitung"][0];
    	echo '<input name="leitung" value="' . $leitung . '" />';
     function cpt_workshop_daten_speichern (){
    	global $post;
    	update_post_meta($post->ID, "art", $_POST["art"]);
    	update_post_meta($post->ID, "datum", $_POST["datum"]);
    	update_post_meta($post->ID, "ort", $_POST["ort"]);
    	update_post_meta($post->ID, "leitung", $_POST["leitung"]);

    In the overview page, I just do not get the values displayed. The code in the functions.php:

       function cpt_workshopseite_spalten($columns){
          $columns = array(
                     "cb" => "<input type=\"checkbox\" />",
                     "title" => "Workshoptitel",
    		 "datum" => "Datum",
                     "ort" => "Ort",
                     "date" => "Hinzugefügt"
          return $columns;
       function cpt_workshopseite_neue_spalte($column){
          global $post;
          if ("datum" == $column) {
             $custom = get_post_custom();
             echo $custom["datum"][0];
          elseif ("ort" == $column) {
             $custom = get_post_custom();
             echo $custom["ort"][0];

    What am I doing wrong ?

    The page I need help with: [log in to see the link]

    Your action hook tag to output table cells should be "manage_workshopseite_posts_custom_column"

    This action passes two parameters to your callback, the column ID and the post ID. Both are essential to outputting the correct value. Pass the post ID to get_post_custom(). There’s no way for this function to know what ID to get data for unless it’s provided. This is not like a post Loop situation on the front end where current post data can be pulled from global $post. It must be specified.
