Default values for max property depending on field type?

[RKlingler]

When I enter a long text into a field with the type "Text", I get the following error message when saving the content element:

SQL error: "An exception occurred while executing a query: Data too long for column 'some_field' at row 1"

Database columns for text fields are by default created as VARCHAR - which is fine. When using the default TYPO3 fields like header, subheader, etc. the backend form automatically makes sure I don't enter text that is longer than the database can store. It does that by adding a maxlength attribute and a character count below the field. On custom fields, this doesn't seem to be the case though.

I could circumvent the issue by adding max: 255 to every custom field I define, which would solve the issue. However, it would be quite tedious to update and maintain all of the field definitions.

Would it be possible and beneficial to make 255 the default value of the max property on "Text" fields (and maybe others accordingly) so that custom fields behave like the default TYPO3 fields, in this regard?

I'm using Content Blocks 0.7 with TYPO2 12. I didn't test this on a more up to date version, but judging by the documentation I assume there is also no default max value in never versions.

Interesting. I need to think about what impact this could have to add this for every Text field by default. This would affect everyone for sure.

The max field is also used in TYPO3 v13 for handling the size of the db column. So adding max 255 would not change the db at least. It would also still be possible to override the value. So maybe we could do this safely.
