In this code I have an input having name student_list where I am uploading only csv file. Now, I want to import data from csv file into database but right now it can't work. So, How can I do this ? Please help me.
Thank You

Answer 1

Unless you have some compelling reason to perform the import in code, I suggest you look at Pentaho (https://sourceforge.net/projects/pentaho/), which can upload data from a csv file to most popular databases.

Hey you need to add the library csvReader in your project and use the below code to setup this helps you lot
public function student(){
$this->load->library('CSVReader');
if (isset($_FILES['csv']))
{
if($_FILES["csv"]["error"] > 0)
{ //if there was an error uploading the file
$this->session->set_flashdata('bulkUploadError', 'Invalid CSV File.');
redirect('/');
}
//Store file in directory "upload" with the name of "uploaded_file.txt"
$storagename = "csv" . date('m-d-Y') . ".xls";
move_uploaded_file($_FILES["csv"]["tmp_name"], realpath(dirname(__FILE__) . '/../../..') . "/uploads/" . $storagename);
if ($file = fopen(realpath(dirname(__FILE__) . '/../../..') . "/uploads/" . $storagename, 'r+'))
{
$result = $this->csvreader->parse_file('uploads/' . $storagename);
$finalResult = $array = array_values(array_filter($result));
$this->data['worksheet'] = $finalResult;
foreach ($this->data['worksheet'] AS $key => $val)
{
$data['id'] = $val['table field name'];
$this->common->save('table_name',$data);
}
}
}
}

You can use PHPExcel to fetch data and insert it to database:
https://github.com/PHPOffice/PHPExcel
<?php
$target_dir = "/tmp/";
$target_file = $target_dir . basename($_FILES["students_list"]["name"]);
$FileType = pathinfo($target_file,PATHINFO_EXTENSION);
$filename = $_FILES["students_list"]["name"];
if (isset($_FILES["students_list"])) {
if($FileType == "csv" ) {
if (move_uploaded_file($_FILES["students_list"]["tmp_name"], $target_file)) {
$target_file = $target_dir . $filename;
set_include_path(get_include_path() . PATH_SEPARATOR . 'resources/imported_file/');
include 'PHPExcel/IOFactory.php';
try {
$objPHPExcel = PHPExcel_IOFactory::load($target_file);
} catch(Exception $e) {
die('Error loading file "'.pathinfo($filename,PATHINFO_BASENAME).'": '.$e->getMessage());
}
$allDataInSheet = $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
$arrayCount = count($allDataInSheet); // Here get total count of row in that Excel sheet
for($i=2;$i<=$arrayCount;$i++){
$name = trim($allDataInSheet[$i]["A"]);
$email = trim($allDataInSheet[$i]["B"]);
$phone = trim($allDataInSheet[$i]["C"]);
$uploaded_date = trim($allDataInSheet[$i]["D"]);
$session = trim($allDataInSheet[$i]["E"]);
$client_id = trim($allDataInSheet[$i]["F"]);
$class = trim($allDataInSheet[$i]["G"]);
$insert = $db->Queryinsert("students",array('',$name,$email,$phone,$uploaded_date,$session,$client_id,$class));
}
}
}
}
?>
This sample helps you to get data from csv file as row by row and after row 1 that involves column title, you try to get other rows then insert them to database.
In top of script i am saving file in /tmp/ folder and then doing needed actions.
You must set your own folder directions and needed Codeigniter syntaxes in this snippet.
