[TYPO3-project-formidable] Added new options for the STANDARD validator

[Manuel Rego Casasnovas]

Hello everyone,

I've developed four new options for the STANDARD validator, this options
are lessthan, lessequalthan, morethan and moreequalthan (like the sameas
option).

I use this options to validate data fields, the initial date must be
less than the final date. For example:
        <renderlet:DATE name="initial_date">
            <validators>
                <validator:STANDARD>
                    <required message="Initial date is required" />
                    <lessequalthan value="final_date" message="Initial
date greater than final date" />
                </validator:STANDARD>
            </validators>
        </renderlet:DATE>
        <renderlet:DATE name="final_date">
            <validators>
                <validator:STANDARD>
                    <required message="Final date is required" />
                </validator:STANDARD>
            </validators>
        </renderlet:DATE>

I modified the _doTheMagic function in the class
formidable_mainvalidator. I've added the next lines:
            if($this->oForm->_navConf("/lessthan", $aConf) !== FALSE) {

                $lessthan =
trim($this->oForm->_navConf("/lessthan/value/", $aConf));

                $this->oForm->_debug(null, "VALIDATOR[" .
$aInfos["TYPE"] . "][lessthan '" . $lessthan . "'] on '" . $sName . "',
TYPE [" . $aElement["type"] . "]");
                // le champ doit �tre identique � un autre champ
                // on v�rifie

                $oLessRdt = $this->oForm->aORenderlets[$lessthan];
               
                $lessvalue = $oLessRdt->_flatten(
                    $this->oForm->oDataHandler->_getThisFormData(
                        $oLessRdt->_getName()
                    )
                );
               
                if(!$this->_isLessThan($value, $lessvalue)) {
                    $message =
$this->oForm->_getLLLabel($this->oForm->_navConf("/lessthan/message/",
$aConf));
                    $this->oForm->_declareValidationError($sName,
"STANDARD:lessthan", $message);
                }
            }
           
            if($this->oForm->_navConf("/lessequalthan", $aConf) !== FALSE) {

                $lessequalthan =
trim($this->oForm->_navConf("/lessequalthan/value/", $aConf));

                $this->oForm->_debug(null, "VALIDATOR[" .
$aInfos["TYPE"] . "][lessequalthan '" . $lessequalthan . "'] on '" .
$sName . "', TYPE [" . $aElement["type"] . "]");
                // le champ doit �tre identique � un autre champ
                // on v�rifie

                $oLessEqualRdt = $this->oForm->aORenderlets[$lessequalthan];
               
                $lessequalvalue = $oLessEqualRdt->_flatten(
                    $this->oForm->oDataHandler->_getThisFormData(
                        $oLessEqualRdt->_getName()
                    )
                );
               
                $value = $oLessEqualRdt->_flatten($value);
               
                if(!$this->_isLessEqualThan($value, $lessequalvalue)) {
                    $message =
$this->oForm->_getLLLabel($this->oForm->_navConf("/lessequalthan/message/",
$aConf));
                    $this->oForm->_declareValidationError($sName,
"STANDARD:lessequalthan", $message);
                }
            }
           
            if($this->oForm->_navConf("/greaterthan", $aConf) !== FALSE) {

                $greaterthan =
trim($this->oForm->_navConf("/greaterthan/value/", $aConf));

                $this->oForm->_debug(null, "VALIDATOR[" .
$aInfos["TYPE"] . "][greaterthan '" . $greaterthan . "'] on '" . $sName
. "', TYPE [" . $aElement["type"] . "]");
                // le champ doit �tre identique � un autre champ
                // on v�rifie

                $oGreaterRdt = $this->oForm->aORenderlets[$greaterthan];
               
                $greatervalue = $oGreaterRdt->_flatten(
                    $this->oForm->oDataHandler->_getThisFormData(
                        $oGreaterRdt->_getName()
                    )
                );
               
                if(!$this->_isGreaterThan($value, $greatervalue)) {
                    $message =
$this->oForm->_getLLLabel($this->oForm->_navConf("/greaterthan/message/",
$aConf));
                    $this->oForm->_declareValidationError($sName,
"STANDARD:greaterthan", $message);
                }
            }
           
            if($this->oForm->_navConf("/greaterequalthan", $aConf) !==
FALSE) {

                $greaterequalthan =
trim($this->oForm->_navConf("/greaterequalthan/value/", $aConf));

                $this->oForm->_debug(null, "VALIDATOR[" .
$aInfos["TYPE"] . "][greaterequalthan '" . $greaterequalthan . "'] on '"
. $sName . "', TYPE [" . $aElement["type"] . "]");
                // le champ doit �tre identique � un autre champ
                // on v�rifie

                $oGreaterEqualRdt =
$this->oForm->aORenderlets[$greaterequalthan];
               
                $greaterequalvalue = $oGreaterEqualRdt->_flatten(
                    $this->oForm->oDataHandler->_getThisFormData(
                        $oGreaterEqualRdt->_getName()
                    )
                );
               
                if(!$this->_isGreaterEqualThan($value,
$greaterequalvalue)) {
                    $message =
$this->oForm->_getLLLabel($this->oForm->_navConf("/greaterequalthan/message/",
$aConf));
                    $this->oForm->_declareValidationError($sName,
"STANDARD:greaterequalthan", $message);
                }
            }


And I've added the next functions:
        function _isLessThan($value1, $value2) {
            return ($value1 < $value2);
        }
       
        function _isLessEqualThan($value1, $value2) {
            return ($value1 <= $value2);
        }
       
        function _isGreaterThan($value1, $value2) {
            return ($value1 > $value2);
        }
       
        function _isGreaterEqualThan($value1, $value2) {
            return ($value1 >= $value2);
        }


On the other hand I've made calls to the _flatten function (not the
_unFlatten), and I've needed change the two calls to the _unFlatten
function for the _flatten function. The lines:
http://test.kunstvaerker.dk/html/classformidable__mainvalidator.html#l00017
http://test.kunstvaerker.dk/html/classformidable__mainvalidator.html#l00069

I think that you can add this new options to the next FORMidable release.

Best regards,
