I need help here. I am creating a system where the user will be able to update the product stock by uploading the stock of the products according to the id that has been assigned to the product. 
this is how my products table in  looks like in mysql database

I tried the code below but all i could not update my data into my database. And there's not error shown on my code. I do not know what is wrong with my codes. Please help me.
below the code that i use for uploading the CSV file to the data of my product_stock. 

<?php 
include 'conn.php';
if(isset($_POST["add_stock"]))
{
 if($_FILES['product_file']['tmp_name'])
 {
  $filename = explode(".", $_FILES['product_file']['tmp_name']);
  if(end($filename) == "csv")
  {
   $handle = fopen($_FILES['product_file']['tmp_name'], "r");
   while($data = fgetcsv($handle))
   {
    $product_id = mysqli_real_escape_string($conn, $data[0]);
    $product_stock = mysqli_real_escape_string($conn, $data[1]);  
    $product_status = 1 ;
    $query = "UPDATE products SET `product_stock` = '$product_stock', `product_status` = '$product_status' WHERE id = '$product_id'";
    mysqli_query($conn, $query);
   }
   fclose($handle);
   header("location: upload-product.php?updation=1");
  }
  else
  {
   echo '<script>alert("An error occur while uploading product. Please try again.")
   window.location.href = "upload-product.php"</script>';
  }
 }
 else
 {
  echo '<script>alert("No file selected! ")
  window.location.href = "upload-product.php"</script>';
 }
}
if(isset($_GET["updation"]))
{
  echo '<script>alert("Product Stock Updated successfully!")</script>';
}
?>

This is the template that i require user to key in and saved it in CSV format before uploading it. 

HI All,

I have a form submission that uploads a photo as well as submitting other data.

I would like to change the name of the photo to the id of the person record (created automatically on by the database) then a hyphen, then their first name and lastname. (i am flexible on this).

This file name will also need to be submitted into the person record so the photo and the person can be linked.

I am struggling with this one - but here is the code i have so far.

<?php 
include 'includes/dbconn.php';

$target_dir = "img/people/";
$target_file = $target_dir . basename($_FILES["personHeadshot"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

if ($_SERVER['REQUEST_METHOD']=='POST'){

	$fn = $_POST['fname'];
	$ln = $_POST['lname'];
	$ad1 = $_POST['ad1'];
	$ad2 = $_POST['ad2'];
	$city = $_POST['city'];
	$post = $_POST['postcode'];
	$tel = $_POST['phone'];
	$email = $_POST['email'];
	$crole = $_POST['comRole'];
	$OFA = $_POST['OFA'];
	$playerType = $_POST['playerType'];
	$team = $_POST['primaryTeam'];


	$stmt = $conn->prepare("
	                       INSERT IGNORE INTO person (fname, lname, committee_role_id, player_type_id, team_id, ad1, ad2, city, postcode, mobile, email, on_field_auth_id) 
	                       VALUES (?,?,?,?,?,?,?,?,?,?,?,?)
	                       ");
	$stmt -> bind_param(ssiiissssssi, $fn, $ln, $crole, $playerType, $team, $ad1, $ad2, $city, $post, $tel, $email, $OFA);
	$stmt -> execute();

	// Check if image file is a actual image or fake image
//photo upload
	$check = getimagesize($_FILES["personHeadshot"]["tmp_name"]);
  if($check !== false) {
    echo "File is an image - " . $check["mime"] . ".";
    $uploadOk = 1;
  } else {
    echo "File is not an image.";
    $uploadOk = 0;
  }
//photo upload

	header("location: ../admin-people-list.php");
}
// Check if file already exists
if (file_exists($target_file)) {
  echo "Sorry, file already exists.";
  $uploadOk = 0;
}

// Check file size
if ($_FILES["personHeadshot"]["size"] > 500000) {
  echo "Sorry, your file is too large.";
  $uploadOk = 0;
}

// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
  echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
  $uploadOk = 0;
}

// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
  echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
  if (move_uploaded_file($_FILES["personHeadshot"]["tmp_name"], $target_file)) {
    echo "The file ". basename( $_FILES["personHeadshot"]["name"]). " has been uploaded.";
  } else {
    echo "Sorry, there was an error uploading your file.";
  }
}

Hi,

                        <input type="button" id="add" value="+ add student"  class="btn btn-primary"/>


                  </div>
                </div>
              </div>

my db.table is like this

id  | name  |  mode  | sport  | idstudent_fk

And Im using an algorithm to read the array and every time can save every row, but im usind PDO and im having problems

try{

here i insert data in a table
here i got the last id from that table then ...

if($_POST['name']!="" and $_POST['mode']!="" and $_POST['sport']!=""){
							 	if(is_array($_POST['name'])){
									while(list($key, $name) = each($_POST['name']) 
							 		  and list($val,$mode) = each($_POST['mode'])
							 		  and list($id, $sport) = each($_POST['sport'])){
                             $sql = "INSERT INTO sports(id_studentfk, mode_stu, sport, id_projfk) 
											values(:value, :mode, :sport, :lastid)";
											$statement = $connect ->prepare($sql);
											$statement -> bindParam(':name', $name, PDO::PARAM_INT);
											$statement -> bindParam(':mode', $mode, PDO::PARAM_STR);
											$statement -> bindParam(':sport', $sport, PDO::PARAM_STR);
											$statement -> bindParam(':lastid', $lastid, PDO::PARAM_INT);
									    	$pdoExec = $statement -> execute();
							 		}
}//end if array
}//end if post
} catch (PDOException $e) {
						     print 'ERROR: '. $e->getMessage();
						     print '<br/>Data Not Inserted';
						}

the idea is creating a loop to read the array and every time can insert data. Im using PDO this time is not working, im geeting this error

ERROR: SQLSTATE[HY093]: Invalid parameter number: parameter was not defined
Data Not Inserted

I hope someone can help me to solve this

Hi Everyone,
