PHP not receiving POST data from Swift - php

Question

I'm trying to write to a database and not able to get POST data from Swift into PHP. I've checked everything along the way and the data is present in request.httpBody before sending the request, but I get this error
"SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'order_id' cannot be null"
Also PHP prints an empty array of $request
Any help is appreciated. Racking my brain on this one!
Here's the code
SWIFT:
func saveNewProduct(product: ProductClass) {
//declare parameter as a dictionary which contains string as key and value combination.
let productDict: [String:Any] = ["order_id": product.order_id!,
"product_sku": product.product_sku!,
"product_description": product.product_description!,
"product_base_price": product.product_base_price!,
"product_price": product.product_price!,
"product_min_qty": product.product_min_qty!,
"product_qty": product.product_qty!,
"product_subtotal": product.product_subtotal!,
"product_imageURL": product.product_imageURL!]
let urlString: String = "https://www.mywebsite.com/dbinsertproduct.php"
guard let url = URL(string: urlString) else {
print("Error: cannot create URL")
return
}
//create the session object
let session = URLSession.shared
//create the URLRequest object using the url object
var request = URLRequest(url: url)
//set http method as POST
request.httpMethod = "POST"
do {
request.httpBody = try? JSONSerialization.data(withJSONObject: productDict, options: .prettyPrinted)
} catch let error {
print(error.localizedDescription)
}
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
let task = session.dataTask(with: request, completionHandler: {
data,response,error in
guard error == nil else {
return
}
guard let data = data else {
return
}
do {
//create json object from data
if let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] {
print(json)
// handle json...
}
} catch let error {
print(error.localizedDescription)
}
})
task.resume()
}
PHP:
<?php include("dbclass.php"); ?>
<?php
$postdata = file_get_contents("php://input");
$request = json_decode($postdata, true);
$newProduct = new DBConnector('mysql.mysite.com', 'username', 'password', 'mysiteorders');
$p = $newProduct->dbInsertProduct($request);
error_log($p);
echo ($p);
?>
More PHP:
public function dbInsertProduct($request)
{
try {
$stmt = $this->prepare("INSERT INTO `products` (`order_id`,`product_sku`,`product_description`,`product_base_price`,`product_price`,`product_notes`,`product_min_qty`,`product_qty`,`product_subtotal`,`product_imageURL`) VALUES (:order_id,:product_sku,:product_description,:product_base_price,:product_price,:product_notes,:product_min_qty,:product_qty,:product_subtotal,:product_imageURL);");
$stmt->bindParam(':order_id', $request['order_id']);
$stmt->bindParam(':product_sku', $request['product_sku']);
$stmt->bindParam(':product_description', $request['product_description']);
$stmt->bindParam(':product_base_price', $request['product_base_price']);
$stmt->bindParam(':product_price', $request['product_price']);
$stmt->bindParam(':product_notes', $request['product_notes']);
$stmt->bindParam(':product_min_qty', $request['product_min_qty']);
$stmt->bindParam(':product_qty', $request['product_qty']);
$stmt->bindParam(':product_subtotal', $request['product_subtotal']);
$stmt->bindParam(':product_imageURL', $request['product_imageURL']);
error_log( print_r($request, TRUE) );
$stmt->execute();
} catch(PDOException $e) {
error_log($e->getMessage());
echo json_encode($e->getMessage());
}
}
UPDATE:
The request shows up as GET, not POST (verified with Charles proxy).
As you can see in the code, I'm setting request.httpMethod = "POST". Am I missing something else??

Answer 1

I found that the POST was being changed to GET upon redirect from www.mysite.com to mysite.com. Removing the 'www' did the trick.
