Adding own serverside and clientside validation to femanager forms¶

Picture¶

newField1

Add own clientside (JcavaScript) Validation

newField2

Add own serverside (PHP) Validation

Basics¶

Use TypoScript to override ValidationClass of femanager with own classes – this enables your validation methods
Config the new validation methods via TypoScript
Add translation labels via TypoScript

See https://github.com/einpraegsam/femanagerextended for an example extension how to extend femanager with new fields and validation methods

Step by Step¶

Override Validation Classes with TypoScript¶

config.tx_extbase{
        objects {
                In2code\Femanager\Domain\Validator\ServersideValidator.className = In2code\Femanagerextended\Domain\Validator\CustomServersideValidator
                In2code\Femanager\Domain\Validator\ClientsideValidator.className = In2code\Femanagerextended\Domain\Validator\CustomClientsideValidator
        }
}

New validation classes¶

CustomClientsideValidator.php:

namespace In2code\Femanagerextended\Domain\Validator;

class CustomClientsideValidator extends \In2code\Femanager\Domain\Validator\ClientsideValidator
{

        /**
         * Custom Validator
         *              Activate via TypoScript - e.g. plugin.tx_femanager.settings.new.validation.username.custom = validationSetting
         *
         * @param string $value Given value from input field
         * @param string $validationSetting TypoScript Setting for this field
         * @return bool
         */
        protected function validateCustom($value, $validationSetting)
        {
                // check if string has string inside
                if (stristr($value, $validationSetting)) {
                        return TRUE;
                }
                return FALSE;
        }
}

CustomServersideValidator.php:

namespace In2code\Femanagerextended\Domain\Validator;

class CustomServersideValidator extends \In2code\Femanager\Domain\Validator\ServersideValidator
{

        /**
         * Custom Validator
         *              Activate via TypoScript - e.g. plugin.tx_femanager.settings.new.validation.username.custom = validationSetting
         *
         * @param string $value Given value from input field
         * @param string $validationSetting TypoScript Setting for this field
         * @return bool
         */
        protected function validateCustom($value, $validationSetting)
        {
                // check if string has string inside
                if (stristr($value, $validationSetting)) {
                        return TRUE;
                }
                return FALSE;
        }
}

TypoScript to enable new validation and set labels¶

plugin.tx_femanager {
        settings.new.validation {
                _enable.client = 1
                _enable.server = 1
                username {
                        # Custom Validator - check if value includes "abc"
                        custom = abc
                }
        }
        _LOCAL_LANG {
                default.validationErrorCustom = "abc" is missing
                de.validationErrorCustom = "abc" wird erwartet
        }
}
