Insert CSV file into mysql database - php

Question

I want to insert a csv file in my database using php. I tried the following code but it gives the following error
Fatal error: Call to a member function exec() on null in C:\xampp\htdocs\ICT_project\class.import.php on line 25
<?php
include 'connection.php';
class Import {
private $pdo;
public function __construct() {
$obj_connect = new DBconnect();
$this->pdo = $obj_connect->db_con;
}
public function import_csv() {
$extension= end(explode(".", basename($_FILES['file']['name'])));
if (isset($_FILES['file']) && $_FILES['file']['size'] < 10485760 && $extension=='csv') {
$file = $_FILES['file']['tmp_name'];
$handle = fopen($file, "r");
try {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
//$num = count($data);
$importSQL = "INSERT INTO tbl_applicants(application_no, applicant_name,applicant_email, applicant_mobile, applicant_address) VALUES('$data[0]','$data[1]')";
$this->pdo->exec($importSQL);
}
}
catch(PDOException $e) {
echo $e->getMessage();
}
}
}
My tbl_applicants have five fields named: application_no, applicant_name, applicant_email, applicant_mobile, applicant_address.
In csv file i have tow row of data with above five fields. I do not understand what will be the insert query?
Hi, here is the updated code which works fine. Now I want to skip the first row of my .csv file which generally contains header(id,name, email, address). How can i do this?
<?php
include 'connection.php';
class Import {
private $pdo;
public function __construct() {
$obj_connection = new Db_connection();
$this->pdo = $obj_connection->connection();
}
public function import_csv() {
$extension= end(explode(".", basename($_FILES['file']['name'])));
if (isset($_FILES['file']) && $_FILES['file']['size'] < 10485760 && $extension=='csv') {
$file = $_FILES['file']['tmp_name'];
$handle = fopen($file, "r");
try {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$importSQL = "INSERT INTO tbl_applicants ( application_no, applicant_name, applicant_email, applicant_mobile, applicant_address ) VALUES('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]')";
$this->pdo->query($importSQL);
}
}
catch(PDOException $e) {
echo $e->getMessage();
}
}
}
}

Answer 1

having not seen the data it is just a guess beased on what you have used above but perhaps you just need to add the remaining fields from the csv?
$importSQL = "INSERT INTO `tbl_applicants`
( application_no, applicant_name, applicant_email, applicant_mobile, applicant_address )
VALUES
('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]')"

Answer 2

Please replace this insert query with above query.
$importSQL = "INSERT INTO tbl_applicants
(application_no, applicant_name,applicant_email, applicant_mobile, applicant_address)
VALUES('$data[0]','$data[1]','','','')";
