Having played around with this issue a litte more it seems my problem lies with this section of code:

$vclLockedContent = $_POST['vclLockedContent'];  //lockedcontent
        if (get_post_meta($post_id, 'vclLockedContent', TRUE) != ''){
                update_post_meta($post_id, 'vclLockedContent',$vclLockedContent);
        }
        else{
                add_post_meta($post_id, 'vclLockedContent', $vclLockedContent);
        }

It seems that when I remove all content from my wp_editor box and save it, it means it no longer does an update_post_meta() but always tries to add_post_meta() instead. At least that is my diagnosis.

Can anyone suggest a better way of writing this if statement? I need a way of determing whether to do an add_post_meta or an update_post_meta.

OK let me take a step back.

I have defined my function vclAddtoHead as to take two arguments:

function vclAddtoHead($arg1,$arg2){
echo $arg1;
echo $arg2;
}

I want this function to echo the arguments in the head tags. So thought I needed a function as follows:

add_action(‘wp_head’,’vclAddtoHead’);

But I need at some point to actually give my two arguments to my function. So how do I do this? I thought I had to modify add_action so that it specifies that my function takes two arguments, as follows:

add_action(‘wp_head’,’vclAddtoHead’,10,2);

Am I correct so far?

If so what, now? Where do I actually specify what my two arguments are?

In short how do I pass arguments to a function used in an add_action?
