I’m sorry, I realise i’m reviving an old topic but it seems quite important, and i’m a bit confused now : since wp_kses_post is now used by default on $_POST, i’m not sure what is the point of what @sododesign suggests (on December 8 2015) ?
What am i missing here ? Does it mean the default wp_kses_post doesnt deal with repeater fields correctly ?
Do we still need to worry about ACF front-end forms input sanitization or is it fully and reliably taken care of with thanks to the kses parameter ?
