Answer 1

To remove this error, in your html form you should do the following in enctype:

<form  enctype="multipart/form-data">

The following down is the cause of that error i.e if you start with form-data in enctype, so you should start with multipart:

<form enctype="form-data/multipart">

Apparently the index 'productid' is missing from your html form. Inspect your html inputs first. eg <input type="text" name="productid" value=""> But this will handle the current error PHP is raising.

  $rowID = isset($_POST['rowID']) ? $_POST['rowID'] : '';
  $productid = isset($_POST['productid']) ? $_POST['productid'] : '';
  $name = isset($_POST['name']) ? $_POST['name'] : '';
  $price = isset($_POST['price']) ? $_POST['price'] : '';
  $description = isset($_POST['description']) ? $_POST['description'] : '';

Answer 5

TRY

<?php

  $rowID=$productid=$name=$price=$description="";  

   if (isset($_POST['submit'])) {
      $rowID = $_POST['rowID'];
      $productid = $_POST['productid']; //this is line 32 and so on...
      $name = $_POST['name'];
      $price = $_POST['price'];
      $description = $_POST['description'];

}

Try:

<?php

if (isset($_POST['name'])) {
    $name = $_POST['name'];
}

if (isset($_POST['price'])) {
    $price = $_POST['price'];
}

if (isset($_POST['description'])) {
    $description = $_POST['description'];
}

?>
