So many strange entries in Custom Fields drop down & it affects me posting …

Whenever I try to make a NEW post or EDIT a post,
I need to use Custom Fields as part of the post, as it’s an entertainment blog.

However, when I scroll down to “Custom Fields” section,
– I click on the dropdown list as usual
– I can’t find my OWN custom field keys because the drop down list is filled with these entries…

Let’s just say, the entire drop down list is filled with those.

It doesn’t matter if the post is a draft, published or currently being edited. They are always there.

Whether the fields are the same or new fields, I don’t know. I didn’t really check, because there’s so many.

So, I’ve spent days trawling google to find a piece of code to hide certain words from “custom field drop down”

This is the best code i found…

/* hide custom field “suggestions” from dropdown list */
add_filter( 'postmeta_form_limit', 'wpse_73543_hide_meta_start' );
function wpse_73543_hide_meta_start( $num ) { add_filter( 'query', 'wpse_73543_hide_meta_filter' );return $num;}
function wpse_73543_hide_meta_filter( $query ){
// Protect further queries.
    remove_filter( current_filter(), __FUNCTION__ );
    $forbidden = array ( 'enclosure', 'sharing_disabled', 'voted_IP', 'nxs_snap_sh_TW088576 ', 'nxs_snap_sh_TR0_7784', 'nxs_snap_sh_TW088576 ' ,'snap_MYURL','snapTW','snapFB','snapTR','snapEdIT','bwps_enable_ssl');
    $where     = "WHERE meta_key NOT IN('" . join( "', '", $forbidden ) . "') ";
    $find      = "GROUP BY";
    $query     = str_replace( $find, "$where\n$find", $query );
    return $query;
}

It DOES NOT WORK. The values are still there, and its driving me nuts. What causes this ?

//
Basically, I only want to hide any dropdown values that contain this “nxs_snap_sh_” , that’s all
