Checks

• checkIBAN($iban): Checks if the IBAN is valid by checking the format and by calculating the checksum and also removes whitespaces and changes all letters to upper case.
• checkBIC($bic): Checks if the BIC is valid by checking the format and also removes whitespaces and changes all letters to upper case.
• crossCheckIbanBic($iban, $bic): Checks if IBAN and BIC belong to the same country.
• isNationalTransaction($iban1,$iban2): Checks if both IBANs are belong to the same country.
• checkCharset($str): Checks if the string contains only allowed characters.
• check($field, $input, $options, $version): Checks if the input fits the field. This function also does little format changes, e.g. correcting letter case. Possible field values are (case-insensitive):
  • initgpty: Initiating Party
  • initgptyid: Initiating Party ID
  • msgid: Message ID
  • pmtid: Payment ID
  • pmtinfid: Payment Information ID
  • cdtr: Creditor Name
  • ultmtcdrt: Ultimate Creditor
  • dbtr: Debtor Name
  • ultmtdebtr: Ultimate Debtor
  • ultmtdbtrid: Ultimate Debtor ID
  • iban: IBAN
  • bic: BIC
  • ccy: Currency
  • btchbookg: Batch Booking (boolean as string)
  • instdamt: Instructed Amount
  • rmtinf: Remittance Information
  • ci: Creditor Identifier
  • seqtp: Sequence Type

The $options take an array

Sanitizing

• sanitizeLength($input, $maxLen): Shortens the string if it is to long.
• sanitizeShortText($input,$allowEmpty, $flags): Sanitizes the the charset and shortens the text if necessary.
• sanitizeLongText($input,$allowEmpty, $flags): Sanitizes the the charset and shortens the text if necessary.
• replaceSpecialChars($str): replaces all characters that are not allowed in sepa files by a allowed one or removes them. Take a look at this .xls file for more information Notice: Cyrillic is not supported yet, but greek letters are.
• sanitize($field, $input, $flags): tries to sanitize the input, so it fits the field. Possible fields are
  • cdtr
  • dbtr
  • rmtinf
  • ultmtcdrt
  • ultmtdebtr
  • adrline

Wrappers

• checkAndSanitize($field, $input, $flags, $options): Checks the input and if it is not valid it tries to sanitize it.
• checkAndSanitizeAll(&$inputs, $flags, $options): Takes an array of inputs (field => value) and checks and sanitizes each of the fields. The input array is handed over as reference, so the result will be direct effect the input array. The return value is true, if everything is ok and else a string with problematic fields.

Date functions

• getDate($date, $inputFormat): Returns $date in a SEPA-valid format. You can specify the input format by using the table on this site. By default the german date format (DD.MM.YYYY) is used.
• getDateWithOffset($workdayOffset, $today, $inputFormat): Computes the next TARGET2 day (including today) with respect to an offset.
• getDateWithMinOffsetFromToday($target, $workdayMinOffset, $inputFormat, $today): Returns the target date, if it has at least the given offset of TARGET2 days form today. Else the earliest date that respects the offset is returned.

Patterns

• HTML_PATTERN_IBAN
• HTML_PATTERN_BIC
• PATTERN_IBAN
• PATTERN_BIC
• PATTERN_CREDITOR_IDENTIFIER
• PATTERN_SHORT_TEXT
• PATTERN_LONG_TEXT
• PATTERN_RESTRICTED_IDENTIFICATION_SEPA1
• PATTERN_MANDATE_ID

The HTML_PATTERN_* constants can be used as HTML5 pattern attribute. It is user friendlier than the corresponding PATTERN_* as they allow lowercase characters and whitespaces. This is corrected by the check methods.
