Feature: #92861 - Introduce TCA option "min"
See forge#92861
Description
The new TCA option min allows to define a minimum number of characters
for fields of type input and text. This option simply adds a
minlength attribute to the input field. If at least one character is
typed in and the number of characters is less than min, the FormEngine
marks the field as invalid, preventing the user to save the element.
When using min in combination with max, one has to make sure, the
min value is less than or equal max. Otherwise the option is
ignored.
Empty fields are not validated. If one needs to have non-empty values, it is
recommended to use required => true in combination with min.
Note
This option does not work for text fields, if RTE is enabled.
Impact
Integrators and developers are now able to define a minimum number of characters a simple text or textarea field should have. Editors are forced to provide the specified minimum amount of characters. An alert badge, similar to the one of the max value, will show, how many characters are missing.
