The code below is working nearly flawlessly, however my value for page title on one of my pages keeps coming up
empty after a few page refreshes... It sticks for awhile, then it appears to reset to
empty. I'm thinking I must have a conflict in the code below, but I can't quite figure it.
I'm allowing the user to
set a custom page title for posts as well as pages via a custom "post/page title input field). Can anyone see an obvious issue here that might be resetting the page title to blank?
// ===================
// = POST OPTION BOX =
// ===================
add_action('admin_menu', 'my_post_options_box');
function my_post_options_box() {
if ( function_exists('add_meta_box') ) {
//add_meta_box( $id, $title, $callback, $page, $context, $priority );
add_meta_box('post_header', 'Custom Post Header Code (optional)', 'custom_post_images', 'post', 'normal', 'low');
add_meta_box('post_title', 'Custom Post Title', 'custom_post_title', 'post', 'normal', 'high');
add_meta_box('post_title_page', 'Custom Post Title', 'custom_post_title', 'page', 'normal', 'high');
add_meta_box('postexcerpt', __('Excerpt'), 'post_excerpt_meta_box', 'page', 'normal', 'core');
add_meta_box('categorydiv', __('Page Options'), 'post_categories_meta_box', 'page', 'side', 'core');
}
}
//Adds the custom images box
function custom_post_images() {
global $post;
?>
<div class="inside">
<textarea style="height:70px; width:100%;margin-left:-5px;" name="customHeader" id="customHeader"><?php echo get_post_meta($post->ID, 'customHeader', true); ?></textarea>
<p>Enter your custom html code here for the post page header/image area. Whatever you enter here will override the default post header or image listing <b>for this post only</b>. You can enter image references like so <img src='wp-content/uploads/product1.jpg' />. To show default images, just leave this field empty</p>

<p>Enter your custom post/page title here and it will be used for the html <title> for this post page and the Google link text used for this page.</p>
