使用codeigniter将数据上传到MsSQL中使用适当的参数

I am having a trouble using a parameters, I want to insert the uploaded file into the MsSQL database from the file upload in my webpage. I am using codeigniter as my framework.

Controller

function upload_gen048()
{

$data['filedate']=$this->input->post('fiil');
//print_r ($data);

$this->load->model('navi_model');
$query = $this->navi_model->upload_gen048($data);

Model function upload_gen048($data) {

$x = explode('.',$data['filedate']);

//print_r ($data);

$qString = "";
$qString .= '[dbo].[gen048upload] '; //STORED PROCEDURE
$qString .= "'" .$data['fiil']."','" .$data['filedate']."'";
echo $qString;

View

<form  id="upload" name="upload" action="<?php echo base_url(); ?>index.php/welcome/upload_gen048" method="POST" class="form-horizontal" enctype="multipart/form-data" onsubmit="return verify_upload()" >

<input style="border:1px solid" type="text" onfocus="true"  name="fiil" id="fiil" value=""size="30" />

<input type="file" name="uploadData" id="uploadData" onChange="fileSelect();" style=""/>

here is my Stored Procedure, it is all working when I execute it independently but I cant insert data from my webpage.

ALTER PROCEDURE [dbo].[gen048upload]
(
        @fileDate VARCHAR(20)

)

AS BEGIN

SET NOCOUNT ON

declare @sql varchar(8000),@sourceTable varchar(500), @dynamic varchar(8000), @tablesuffix varchar(10)
select @tablesuffix=upper(substring(datename(m,convert(datetime,@fileDate)),1,3))+convert(varchar,year(convert(datetime,@fileDate)))
print @tablesuffix


create table #logs(
i int identity(1,1),
tableName varchar(50),
status varchar(30)
)

set @sourceTable ='gen_048_'+@tablesuffix
insert into #logs(tableName,status) select @sourceTable,'CREATED'
IF NOT EXISTS (SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'dbo' AND TABLE_NAME = @sourceTable)
BEGIN
    set @sql = '
    CREATE TABLE '+@sourceTable+'
    (

function upload_gen048()
{
    // Here you make a array, with a key 'filedate'
    $data['filedate']=$this->input->post('fiil');
    //print_r ($data);

    $this->load->model('navi_model');
    $query = $this->navi_model->upload_gen048($data);

 function upload_gen048($data) {
     $x = explode('.',$data['filedate']);
     //print_r ($data);
    $qString = "";
    $qString .= '[dbo].[gen048upload] '; //STORED PROCEDURE

// Here you try to get array key 'fiil', but you haven't set that in your code.
    $qString .= "'" .$data['fiil']."','" .$data['filedate']."'";
    echo $qString;

Remove $data['fiil'] and your code should work. Also var_dump($data); to see exactly what is in your array, you would have seen that $data['fiil'] does not exist.
