I am trying to insert records using csv. I want to upload csv to my Application and want to import it in database. Now I have a users table so i want to create users by importing user's csv file. I Know a little about file uploads but nil about importing it into database please help .
See I have done the file upload using : Controller:
public function upload_csv()
{
$this->load->helper('form');
$this->load->helper('url');
//Set the message for the first time
$data = array('msg' => "Upload File");
$data['upload_data'] = '';
//load the view/upload.php with $data
$this->load->view('admin/user/upload', $data);
}
The Another Controller Upload_file
public function upload_it() {
//load the helper
$this->load->helper('form');
//Configure
//set the path where the files uploaded will be copied. NOTE if using linux, set the folder to permission 777
$config['upload_path'] = 'application/views/uploads/';
// set the filter image types
$config['allowed_types'] = 'gif|csv';
//load the upload library
$this->load->library('upload', $config);
$this->upload->initialize($config);
$this->upload->set_allowed_types('*');
$data['upload_data'] = '';
//if not successful, set the error message
if (!$this->upload->do_upload('userfile')) {
$data = array('msg' => $this->upload->display_errors());
} else { //else, set the success message
$data = array('msg' => "Upload success!");
$data['upload_data'] = $this->upload->data();
}
//load the view/upload.php
$this->load->view('admin/user/upload', $data);
}
And The view:
<code>
<?php if($upload_data != ''):?>
<?php var_dump($upload_data);?>
</code>
<img scr="<?php echo $upload_data['full_path'];?>">
<?php endif;?>
<?php echo form_open_multipart('admin/upload_file/upload_it');?>
<input type="file" name="userfile" size="20" />
<br /><br />
<input type="submit" value="upload" />
</form>
Now How do i import a uploaded file into my database ??
From a 2 second Google and the PHP docs :
$csv = array_map('str_getcsv', file('data.csv'));
Then you can loop through the Array and UPDATE
your DB
First change the default_controller value in route.php which lies inside config folder.
$route['default_controller'] = "csv";
Create a controller as csv.php
<?php
class csv extends CI_Controller
{
public $data;
public function __construct()
{
parent::__construct();
$this->load->model('csv_model');
}
function index()
{
$this->load->view('uploadCsvView',$data);
}
function uploadData()
{
$this->csv_model->uploadData();
redirect('csv');
}
}
?>
And create a model as csv_model.php
<?php
class csv_model extends CI_Model
{
function __construct()
{
parent::__construct();
}
function uploadData()
{
$count=0;
$fp = fopen($_FILES['userfile']['tmp_name'],'r') or die("can't open file");
while($csv_line = fgetcsv($fp,1024))
{
$count++;
if($count == 1)
{
continue;
}//keep this if condition if you want to remove the first row
for($i = 0, $j = count($csv_line); $i < $j; $i++)
{
$insert_csv = array();
$insert_csv['id'] = $csv_line[0];//remove if you want to have primary key,
$insert_csv['empName'] = $csv_line[1];
$insert_csv['empAddress'] = $csv_line[2];
}
$i++;
$data = array(
'id' => $insert_csv['id'] ,
'empName' => $insert_csv['empName'],
'empAddress' => $insert_csv['empAddress']
);
$data['crane_features']=$this->db->insert('tableName', $data);
}
fclose($fp) or die("can't close file");
$data['success']="success";
return $data;
}
}
And at last create a view as uploadCsvView.php
<form action="<?php echo site_url();?>csv/uploadData" method="post" enctype="multipart/form-data" name="form1" id="form1">
<table>
<tr>
<td> Choose your file: </td>
<td>
<input type="file" class="form-control" name="userfile" id="userfile" align="center"/>
</td>
<td>
<div class="col-lg-offset-3 col-lg-9">
<button type="submit" name="submit" class="btn btn-info">Save</button>
</div>
</td>
</tr>
</table>
</form>
And create mysql table where data is going to be inserted:
CREATE TABLE tableName(
id INT,
empName VARCHAR( 100 ) ,
empAddress VARCHAR( 100 ),
PRIMARY KEY (id)
)
And most important point:
MySql and Csv file should both be same
Sample csv data is in the following link:
