Custom Fields and menu items

    In my installation, I am required to add a label (think of it like a category, but not a WP cat) to both the blog post’s title, and content. I wrote a plugin that adds a custom field to the title and content using the selected label, and it has been working fine for years, except in the menus.

    Example: Say that I have three labels, L1, L2, and L3. When I create a new post, I click a button to give the title a label, say L1. Then I click another button to give the content a label, say L2.

    When I publish the post, my plugin hooks into the save_post function and adds the label to the posts meta table as a custom field.

    When the post is displayed, the label is displayed via add_filter(‘the_content’, ‘customcontent’);

    The problem is that when the post titles are retrieved from the db on the wp-admin/nav-menus.php page, it doesn’t pull the custom field and only shows the default label.

    When I create and apply the menu, then go to the main page, the value displayed in the custom field/label on the menu is the value of the label on the top post.

    Any ideas on how to fix this?

    Not sure how it adds the label to the title when you’re hooking in to the_content filter. I believe that should be only filtering on post_content field and not post_title

    Ah, I messed that up, William, you’re right. I use the the_title filter for the title, and the_content filter for the content.

    Try adding another hook on the filter nav_menu_attr_title to fire the same function you use on the front-end and see if that works for you.

    I think this is what you mean?

    add_filter('the_title', 'my_the_title');
add_filter('nav_menu_attr_title', 'my_the_title');

    the first filter fires and works, but the second does not.

    Hmm, after looking at this a little more, seems like the_title should be working. It looks like it uses get_the_title() which is filtered by the_title.

    The wp-admin/nav-menu.php code is all over the place though, so it’s kinda hard to follow.

    Actually, where is that add_filter() call located? Is it in a functions.php file for a theme? Is it in a plugin?

    It’s in a MU-plugin

    UPDATE: It seems that when the page is rendered, the nav menu items are filtered via the_title just like the actual titles are in the loop. Is there a way to filter just the posts, and not nav menu items?
