Retrieve and store values into db from uploaded excel file - php

Question

I am trying to save the attendance details for each employee into a db from an excel file as a bulk attendance upload , the code below displays Excel Data Imported Succesfully , but does not store values into the db, the line $last_id=$this->mod_common->add_attendence_data($data_user); is not executed , thats why its not working , How to make this line execute ? As this code was written by some other developer i am finding it difficult to understand.
Controller: admin_list.php
function upload_bulk_attendance(){
$data['htmltext'] = $this->mod_common->get_allleaves();
$this->data['maincontent'] = $this->load->view('maincontents/upload_attendance_sheet', $data,true);

//set to read only
$objReader->setReadDataOnly(false);
//load excel file

Please try this way:-
<?php
public function importContacts($id)
{
if(isset($_POST["Import"]))
{
$filename=$_FILES["file"]["name"];
$f_extension = explode('.',$filename);
$f_extension = strtolower(end($f_extension));
if($f_extension == 'csv') // for import CSV file
{
$file_tmp_name=$_FILES["file"]["tmp_name"];
if($_FILES["file"]["size"] > 0)
{
$file = fopen($file_tmp_name, "r");
$row = array();
while (($emapData = fgetcsv($file, 10000, ",")) !== FALSE)
{
array_push($row, $emapData);
}
fclose($file);
unset($row[0]);
foreach(array_values($row) as $r){
$data = array(
'gc_group_id' => $id,
'gc_user_id' => $this->session->userdata('userId'),
'gc_name' => #$r[1],
'gc_number' => #$r[0],
'gc_email' => #$r[2],
'gc_added_date' => date('Y-m-d'),
);
$this->user_model->add('groups_contact',$data);
array_push($valid_no, $r[0]);
}
fclose($file);
}
}
if($f_extension == 'xlsx' || $f_extension == 'xls')
{
/* PHPExcel library */
set_include_path(get_include_path() . PATH_SEPARATOR . 'Classes/');
require_once APPPATH.'third_party/PHPExcel/IOFactory.php';
$file_tmp_name=$_FILES["file"]["tmp_name"];
try {
$objPHPExcel = PHPExcel_IOFactory::load($file_tmp_name);
} catch(Exception $e) {
die('Error loading file :' . $e->getMessage());
}
$sheetData = $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
unset($sheetData[1]);
foreach(array_values($sheetData) as $s){
$data = array(
'gc_group_id' => $id,
'gc_user_id' => $this->session->userdata('userId'),
'gc_name' => #$s[B],
'gc_number' => #$s[A],
'gc_email' => #$s[C],
'gc_added_date' => date('Y-m-d'),
);
$this->user_model->add('groups_contact',$data);
array_push($valid_no, $s[A]);
}
}

Let me know please if you find any issues.
