Ok I have a wierd issue with custom meta boxes that I am at a loss for.
I am using this class
<?php
class ARIXWP_Meta {
private $meta = null;
public $postid = null;
private $template = null;
function __construct() {
add_action('save_post',array(&$this, 'save_meta_data'));
}
function __destruct() {
$this->meta = null;
$this->postid = null;
$this->template = null;
}
public function init_meta() {
add_action('admin_init',array(&$this, 'add_meta'));
}
public function add_meta() {
if ($this->meta['template'] == $this->template) {
add_meta_box($this->meta['id'], $this->meta['title'], array(&$this, 'format_meta'), $this->meta['post_type'], $this->meta['context'], $this->meta['priority']);
}
}
public function format_meta() {
global $post;
if (!isset($post)) return false;
if ($this->meta['post_type'] != $post->post_type) return false;
$this->set_postid($post->ID);
// Use nonce for verification
echo '<input type="hidden" name="' . $this->meta['nonce_name'] . '" value="', wp_create_nonce(basename(__FILE__)), '" />';
foreach ($this->meta['fields'] as $field) {
// get current post meta data
$meta = get_post_meta($post->ID, $field['id'], true);
if (isset($field['before']) && $field['before'] != "") {
echo '<p class="heading">' . $field['before'] . '</p>';
}
echo '<label for="'. $field['id'] .'" class="arixwp_label">'. $field['name']. '</label><p>';
if (isset($field['desc']) && $field['desc'] != "") {
echo '<p class="arixwp_text">' . $field['desc'] . '</p>';
}
if ( $field['type'] == 'radio' )
echo '<div class="arixwp_radio">';
switch ($field['type']) {
case 'text':
echo '<input type="text" name="'. $field['id']. '" id="'. $field['id'] .'" value="'. ($meta ? $meta : $field['default']) . '" class="arixwp_admin_input" />'. '<br />';
break;

}
break;
case 'checkbox':
echo '<input type="checkbox" name="' . $field['id'] . '" id="' . $field['id'] . '"' . ( $meta ? ' checked="checked"' : '' ) . ' />';
break;
}
if ( $field['type'] == 'radio' )

}
}
public function save_meta_data($post_id) {

$this->meta = unserialize(get_post_meta($this->postid,'_arixwp_field_meta',TRUE));
}
return $this->meta;
}
}
and this is the php to call the class
<?php
$meta_template = '';
$meta_posttype = 'page';

$meta_priority = 'high';
$meta_id = 'page-meta';
$meta_nonce = $meta_id . '-nonce';
$arixwp_meta = new ARIXWP_Meta();
$arixwp_meta->set_postId();
$arixwp_meta->set_template();
$arixwp_template = $arixwp_meta->get_template();
if ($arixwp_template == $meta_template) {
$arixwp_meta->set_meta(array(
//This is the id applied to the meta box
'id' => $meta_id,

$arixwp_meta->init_meta();
}
$arixwp_meta = null;
I am using several instances of this for posts and custom page templates and it works fine. But when just trying to apply it to a generic page. The Meta boxes show when you choose to add a new page. But as soon as you save or publish they dissappear.
