Custom field not saving

CMS & WordPress
1

I’m possibly biting off more than I can choose. I haven’t deal with creating custom fields and panels to this extent before. I’m working off of this tutorial:

http://wefunction.com/2008/10/tutorial-creating-custom-write-panels-in-wordpress/

I have created custom fields for a few post types. The fields display properly for each post type. However the custom fields are only saving properly within one of the post types, “Project”. Based on the tutorial (and my probably questionable code below) can anyone point me in the right direction on how to properly save custom field data. Any tutorials that offer more details would be great.

<?php
		
	//Meta boxes with upload fields
	
	 
if ( is_admin() ) {
    function add_post_enctype() {
        echo "<script type='text/javascript'>
                  jQuery(document).ready(function(){
                      jQuery('#post').attr('enctype','multipart/form-data');
                  });
              </script>";
    }
    add_action('admin_head', 'add_post_enctype');
}

The first question is are your custom posts showing up correctly?

3

I’m not sure what you mean. Are the custom fields from the custom fields that are saving, working? Yes. Are my custom post types showing up in the admin? Yes.

4

Any other advice on how to do this? Or a tutorial somewhere on creating custom fields?
