FORMCHECKER
PHP5
Data validation package
Instanciation :
formChecker::__construct ($loc = 'FRA');
$loc (string) => alpha 3 country code localization string
Example :
$oChecker = new formChecker ('FRA');
Public methods :
formChecker::validate ($mString, $sName, $cPattern, $aOptions = null, $bMandatory = true)
apply a validation pattern for the data
$mString (string) => data to be validated
$sName (string) => user defined name to be applied to the data. Used in the returned messages.
$cPattern (formChecker const) => validation pattern constant
$aOptions (array) (optionnel) => array of options. null if no option
$bMandatory (boolean) (optionnel) => true if the data is mandaotry (empty = not valid), false if not (empty = valid).
@return (boolean) true is data is valid, false if not.
Example
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('strict_length' => 5, 'not_starting_with' => array ('00')))
formchecker::sanitizeStr ($mString, $aOptions = array ('addslashes', 'htmlentities'))
Sanitize the data as a string
$mString (string) => data to be sanitized
$aOptions (array) => array of options
@return (string) sanitized data
Available options :
addslashes => apply the addslashes () function to the data
htmlentities => apply the htmlentities () function to the data
urlencode => apply the urlencode () function to the data
trim => apply the trim () function to the data
mssqlEscape => escape quotes for mssql (' => '')
Example :
$maChaine = $oChecker -> sanitizeStr ('maChaine ', array ('trim'));
formChecker::sanitizeInt ($mString, $aOptions = array ('onlyInt'))
Sanitize the data as an integer
$mString (string) => data to be sanitized
$aOptions (array) => array of options
@return (string) sanitized data
Available options :
onlyInt => apply a regular expression to retrieve ONLY integer characters in the data
Example :
$myInt = $oChecker -> sanitizeInt ('12-32-15', array ('onlyInt'));
// $myInt = '123215'
formChecker::sanitizeUserFunc ($mString, $aOptions = array ('user_func' => '', 'user_func_params' => array ()))
Sanitize the data using a user defined function
$mString (string) => data to be sanitized
$aOptions (array) => array of options
@return (string) sanitized data
Options :
user_func => mandaotory. Value MUST be the name of the function to be used.
user_func_params => optional. Must be an array of parameters waited by the user defined function LESS the data itself.
So the function must accept AT LEAST 1 parameter : the data itself. If there ara more parameters, the data MUST BE in the last parameter.
Example :
$sToBeSanitized = $oChecker -> sanitizeUserFunc ($sToBeSanitized, array ('user_func' => 'mySanitizer'));
Pattern :
These patterns are class constants.
const VALIDATE_EMAIL => Email validation pattern
const VALIDATE_INT => Integer validation pattern
const VALIDATE_TEXT => Text validation pattern
const VALIDATE_URL => URL validation pattern
const VALIDATE_REGEXP = => User defined regular expression validation pattern
const VALIDATE_USER_FUNC = => User defined function validation pattern
Options :
These are options to be applied to the used pattern. You can cumulate these options.
For all the patterns :
forbidden => (string) ou (array) gives the value(s) forbidden for the data
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('forbidden' => array ('12345', '6789')))
or
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('forbidden' => '12345'))
allowed => (string) ou (array) gives the allowed value(s) for the data
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('allowed' => array ('12345', '6789')))
or
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('allowed' => '12345'))
min_length => (int) minimal length for the data
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('min_length' => 6))
max_length => (int) maximal length for the data
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('max_length' => 4))
strict_length => (int) mandatory length for the data
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('strict_length' => 5))
starting_with => (array) array of values the data must start with (at least 1)
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('starting_with' => array ('1', '3', '5')))
not_starting_with => (array) array of values the data must NOT start with
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('not_starting_with' => array ('1', '3', '5')))
Regexp pattern only (formChecker::VALIDATE_REGEXP)
regexp => (string) user defined regular expression that must be used to validate the data
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_REGEXP, array ('regexp' => '@(bla|bli)@'))
User defined function pattern only (formChecker::VALIDATE_USER_FUNC)
user_func => (string) user defined function name used to validate the data
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_USER_FUNC, array ('user_func' => 'myFunc'))
user_func_params => (array) array of parameters needed by the function LESS the data itself
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_USER_FUNC, array ('user_func' => 'myFunc', 'user_func_params' => array ('param')))
NOTICE : this pattern's validation method will anyway add at the end of the array of parameters the data (even if you have no parameter).
So, your function MUST implements at least 1 parameter (the data itself), and if there are more paramaters, the data MUST be in the last parameter of your function.
Your function MUST return a boolean : true or false; true if validation is ok, false if not. The pattern does not wait for any other return value.
Integer pattern only (formChecker::VALIDATE_INT)
min_range => (int) minimum value for the data
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('min_range' => 12344))
max_range => (int) maximum value for the data
Example :
$bRes = $oChecker -> validate ('12345', 'zip code', formChecker::VALIDATE_INT, array ('max_range' => 12346))
