  • esc_attr() for anything that echoes in an HTML attribute. Especially on line 72!

Hi, it's so great. I have a question. Do you know to implement group of input type checkbox to this solution? I want to want to be able to save more than one value for the same field. I appreciate any help. Thank you.

Hi,
Could you help me how can I unserialize the result?
I made my own filed and this is the result:

Thanks,
