Validation Framework

Validators

• Will be converted from FLOW3 to t3lib_validation (automatically)
• TODO: Tear apart the ValidatorResolver into a SimpleValidatorResolver (just containing createValidator() ), and an AdvancedValidatorResolver (containing reflection stuff, etc)??
• Error Messages:
  • in TYPO3 v4, we will use the following language keys: [full class name in lowercase].[errorName] -- Example: t3lib_validation_validator_stringlengthvalidator.length_exceeded
    • Please don't use a dot as separator, if you use a dot, you can't overwrite it by TypoScript. Or fix the TS-Parser ;) (F. Nägler)
  • There will be a new method inside AbstractValidator which resolves these language keys
  • Language Strings will contain sprintf-placeholders
  • Overriding messages: There will be a method overrideLanguageKey($errorName, $newLocallangKey) with which one can override single messages in validators.
  • TODO: How to do this in FLOW3??
• Take a look at the validator classes in EXT:feuserregister:
  • https://svn.typo3.org/TYPO3v4/Extensions/feuserregister/trunk/classes/validators/

Converters and Filters

• We will use the same API as in FLOW3 for them, and the same base classes.
• Take a look at the transformer classes in EXT:feuserregister:
