Hi,

I have a Form and i am submitting them like using

    function submit($formid = null,$fillerid=null)
    {

		$this->data['Result']['form_id']=$formid;
		$this->data['Result']['submitter_id']=$fillerid;
		$this->data['Result']['submitter']=$this->Session->read('filler');
		echo "submitter: ".$this->Session->read('filler');
                $results=$this->Form->hasResults($this->data);
				//echo http_build_query($_POST);

         if(empty($results)){
				foreach ($_POST as $key => $value):
						if(is_array($value)){
					               $value = implode('', $_POST[$key]);
					               $this->data['Result']['value']=$value;
					    }
					    else{
								   $this->data['Result']['value']=$value;
					 	}
					   	$this->data['Result']['form_id']=$formid;
					   	$this->data['Result']['submitter_id']=$fillerid;	
						$this->data['Result']['label']=Inflector::humanize($key);

						$this->data['Result']['submitter']=$this->Session->read('filler');
						$this->Form->submitForm($this->data);
				endforeach;

			$this->Session->setFlash('Your entry has been submitted.');


  		}

I am having A fORM LIKE

Last Name
 	





  
Age
 	

	            



  
Address
   	




  
Date Of Joining




  
Email - Id
   	





  

Personal Number

  
  





  
Gender

MaleFemale

  
Official Number




     
Experience
    FresherBelow 5 YrsAbove 10 yrs

actually My input has the names as
Firstname
Last Name
Age
Address
Date of joining
Email - id
Personal Number
Gender
Official Number

But when i use Inflector::humanize($key) for saving the names which has white space characters they have converted into like Date Of Joining i.e.., O and J becomes Capital letters... But i need to save them as such as Date of joining..
How to do so???
