Ability to create restricted individual pages/posts

I was looking for the ability (in other plugins) to a way to restrict users who have the ability to edit posts or pages to not be able to edit specific posts or pages. In particular, I don’t want anyone to edit my frontier post shortcodes!

I realized that because Frontier Post changes the URL for the Edit link at the bottom of the page, I could use that function in FP to check for a Custom Field.

More specifically, the function frontier_edit_post_link( $url, $post_id ) in frontier-post.php

If I add something like:
$restrict_edit = get_post_meta( $post_id, ‘fp_restrict_edit’, true );
echo “EDIT RESTRICTED: “;
if ($restrict_edit) {
$url = ‘/’;
return $url;
}

right after checking for whether the user is admin, then I can restrict access to anyone but admin from editing a page/post/whatever by simply adding a custom field “fp_restrict_edit” to any page I don’t want someone to edit. this would be a super easy function to add to this plugin that would address a complicated problem for people, and let them protect those complex FP shortcodes.

Adding this will do the same thing:
function rgs_edit_post_link( $url, $post_id )
{
// Remove the link if a custom field is restrict_edit
// to be used on pages/posts with custom shortcodes to prevent
// them being screwed up
$restrict_edit = get_post_meta( $post_id, ‘restrict_edit’, true );
if (!$restrict_edit || current_user_can(‘administrator’)) {
return $url;
} else {
echo ‘EDIT RESTRICTED’;
}
}
add_filter( ‘get_edit_post_link’, ‘rgs_edit_post_link’, 15, 2 );
