NGG Cusotm field issue

This is actually a problem with NGG Custom fields. Version 1.2.3 of that plugin uses a new filter from NGG 2.X, which isn’t supported by NextCellent Gallery.

Please contact the plugin author and point them to this post or give them this information:

To make it work again with NextCellent, replace

add_filter('ngg_manage_gallery_fields', 'nggcf_add_gallery_col', 11, 2);
		function nggcf_add_gallery_col($fields=array(), $gallery=NULL) {
			$fields['left']['ngg_cf_options'] = array(
				'callback'	=> 'nggcf_admin_gallery_col',
				'label'		=>	_('Custom Fields:'),
				'tooltip'   =>  NULL,
				'id'		=>	'ngg_cf_options'
				);

			return $fields;
		}

		function nggcf_admin_gallery_col($gallery=array()) {
			global $wpdb;
			$fields = nggcf_get_field_list(NGGCF_GALLERY, $gallery->gid);

			echo '<strong>Custom Columns</strong><hr /><input type="hidden" name="nggcf_gallery[ngg_gallery_id]" value="'.$gallery->gid.'" />';

			foreach ((array)$fields as $key=>$val) {

				echo htmlspecialchars($val->field_name).'<br />';

				$value = $wpdb->get_row("SELECT * FROM ".$wpdb->prefix."nggcf_field_values WHERE pid = '".$wpdb->escape($gallery->gid)."' AND fid = '".$val->id."' AND ngg_type = '".NGGCF_GALLERY."'");
				switch($val->field_type) {
				case NGGCF_FIELD_TYPE_INPUT :
					echo '<input name="nggcf_gallery['.$val->id.']" style="width:95%;" value="'.esc_attr($value->field_value).'" />';
					break;
				case NGGCF_FIELD_TYPE_TEXTAREA :
					echo '<textarea name="nggcf_gallery['.$val->id.']" style="width:95%;">'.esc_attr($value->field_value).'</textarea>';
					break;
				case NGGCF_FIELD_TYPE_SELECT :
					$opts = explode(",", $val->drop_options);
					echo '<select name="nggcf_gallery['.$val->id.']">';
					echo '<option value=""></option>';
					foreach ((array)$opts as $optVal) {
						echo '<option value="'.trim(esc_attr($optVal)).'" '.(trim(esc_attr($optVal)) == esc_attr($value->field_value) ? ' selected="selected"' : '').'>'.trim(esc_attr($optVal)).'</option>';
					}
					echo '</select>';
					break;
				}
				echo '<br />';
			}
		}
	//}

This should be done with all new hooks and stuff they use from NextGEN 2.X.

Excellent Niko, i figured out the filter problem, but not the workaround!!!
Great!
