I have a matrix field with around 26 block types with between 2-6 fields on each. It seems like I've hit a limit and cannot add any more fields to any of the block types. I can add a field if i delete one.

I get the following error "Undefined index: type"

/var/www/dev/domain.co.uk/craft/app/fieldtypes/MatrixFieldType.php(118)

I'm running Craft Pro 2.1.2563

  • Have you tried upgrading? There have been a fair few Matrix fixes since then. You could upgrade locally first to see if it affects anything else.

  • Yes, I tried upgrading this morning but still get the same problem locally. It seems like everything isn't getting posted when saving the matrix field.

  • In that case it might be best to submit a support request to P&T through your control panel? They are usually very swift to respond.

  • I wonder if it's related to this issue... There are a few places around the system with an inherent limit of 100. You say you have 2-6 fields (average 4) per block type... ~25 * ~4 = ~100

There's about a 99% chance you're bumping into your php.ini file's max_input_vars value and/or its post_max_size. If you bump those to higher values, it should start working as expected.

Note that you may have to restart your web server for the settings to take affect.

    For nginx users, make sure you run service php5-fpm reload before you restart nginx, the changes did not take affect until I did that. Thanks Brad!

  • I set post_max_size to 50 and max_input_vars to 500 . I thoughtthis is enough. We still have problems here...
