Content dissapears on update

Strange problem – I’ve created a content management system for a site using ACF. The default classic editor works OK but when I use any of my fields the changes are dissapearing on save.

So I create content, preview them – all looks good. Go back to edit and the content has dissapeared from the backed. If I hit update it will override the content and wipe it out.

It’s a multisite install.

I get this issue now and again and usually comes from conflicting naming convention on your fields or if you have some field groups registered in both json and in the DB that are sharing field keys for some reason (human error)

I suspect my naming conventions are conflicting – should the variable be different for each subfield or does the subfield name itself need to be different.

I think I’m dreading the answer…

Since you are using the layout custom field, you should probably also take a look at this post…

php-input-variables-exceeded-1000

On complex field groups it is possible for the number of form variables submitted to exceed your web server’s maximum number of allowed variables per post. This happened to me on what seemed like a field group that wasn’t all that big. But once you start repeating layouts, the number of inputs can become quite large.

Until the developers start using a different method of saving data (like I suggested in my post) you will either have to change the configuration of your web server (not always possible on shared web hosting) or figure out a different way to do it.

Thanks @wp_kc – it appears to be fixed by increasing the max_input_vars to 2000
