this is my ajax code

$(document).on('click', '.submit-form-ajax-validation', function(e)

    e.preventDefault();
    var fonturl = $('#post-form').attr('action');
    var method=$('#post-form').attr('method');

    $.ajax({
    url : fonturl,
    type: method,
    data: $('#post-form').serialize(),
    async: false,
    success: function(data)
    {
        if(data.msg=="Yes")
        {
             $(document).trigger('showMessage','<a href="javascript:void(0)" id="cross_icon_rq" ><i class="fa fa-times-circle-o cross_icon_cs" class=""></i></a><div class="text_success_cs"><strong>Success!</strong><br />'+data.text+'</div>');
             $('#post-form').reset;
        }else if(data.msg=="No")

        }else if(data.msg=="validation_error")  
        {
            var msg='';
                  $.each(data.error, function(index,element)                                
                        {

                              //console.log(element);
                                if(index.length>0)
                                    {
                                        $('#'+index).addClass('validation_error_cs');

                        });
                        $('.responseMessage_rq').removeClass('error_block_cs');
                        $('.responseMessage_rq').removeClass('success_block_cs');
                        $('.responseMessage_rq').addClass('error_block_cs');

        }   

    }
    });
});

this is my controller

                if($input['image_Name']!='')
                {
                    $filename = $_FILES['image_Name'];
                    if (!empty($filename))
                    {
                      $filename = Input::file('image_Name')->getClientOriginalName(); 
                      $splitName = explode(".", $filename);

                      $fileExt = end($splitName);
                      $newFileName  = strtolower('profile_image_'.time().'.'.$fileExt);
                      //
                      $destinationPath = base_path(). '/public/uploads/profile_image/';
                      //dd($destinationPath);
                      if(!file_exists($destinationPath))
                      {
                          mkdir($destinationPath,0777,true);
                      }
                      $rules = array('myfile'  => 'mimes:jpg,jpeg,png');
                      $size = Input::file('image_Name')->getSize();

                      $data = array('myfile' => Input::file('image_Name'));

                      $validation = Validator::make($data,$rules);
                       //dd($size);
                        if ($validation->fails())
                        {
                            $response['Success']="format_na";
                              return $response;
                        }

Answer 1

It is because the form attribute enc-type is missing

Pass:

<form method="post" enctype="multipart/form-data"></form>

enc-type is mandatory for file upload
