I have been struggling to figure out how to get my php code working with my database by searching online, but I'm having trouble understanding it all! That's why I decided to reach out and ask for help or guidance on this issue. Any assistance would be greatly appreciated!
Question: How can I insert JSON formatted data into a MySQL database?
String Request Code in Android
public void insertCartProducttoDatabase() {
StringRequest stringRequest = new StringRequest(Request.Method.POST,
Constants.cartdata_url,
new com.android.volley.Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response);
if (!jsonObject.getBoolean("error")) {
Toast.makeText(getApplicationContext(),
jsonObject.getString("message"),
Toast.LENGTH_LONG).show();
finish();
} else {
Toast.makeText(getApplicationContext(),
jsonObject.getString("message"),
Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("response", "" + error);
}
}) {
@Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put(KEY_VC_ARRAY, convertedArray);
//params.put(KEY_VC_BRANCH, branchid);
return params;
}
};
RequestHandler.getInstance(this).addToRequestQueue(stringRequest);
}
logcat Result: Here is the array result from my recycler view
[
{
"productname": "Siopao",
"quantity": "3",
"totalprice": 1500
},
{
"productname": "Siomai",
"quantity": "3",
"totalprice": 297
},
{
"productname": "Burger",
"quantity": "4",
"totalprice": 200
}
]
PHP CODE DB Operations.php (UPDATEDv2)
//INSERT CART PRODUCTS
public function insertIndividualCart($cartarray){
$receivedArray = $_POST['cartarray'];
$new_array = json_decode($receivedArray,true);
var_dump($new_array);
$stmt = $this->con->prepare("INSERT INTO `cart_data` (`cartid`, `productname`, `quantity`, `totalprice`, `created`)
VALUES (NULL, ?, ?, ?, CURRENT_TIMESTAMP )");
foreach($new_array as $row){
$stmt->bind_param('ssi', $row['productname'], $row['quantity'], $row['totalprice']);
if($stmt->execute()){
return 1;
}else{
return 2;
}
}
}
PHP CODE cartData.php
<?php
require_once '../DbOperations.php';
$response = array();
if($_SERVER['REQUEST_METHOD']=='POST'){
if(
isset($_POST['cartarray'])
){
//operations data
$db = new DbOperations();
$result = $db->insertIndividualCart(
$_POST['cartarray']
);
if($result == 1){
$response['error'] = false;
$response['message'] = "Success";
}elseif($result == 2){
$response['error'] = true;
$response['message'] = "Failed, Error Occured";
}
}else{
$response['error'] = true;
$response['message'] = "Required Field are missing";
}
}else{
$response['error'] = true;
$response['message'] = "Invalid Request";
}
echo json_encode($response);
I am aware that my php code in Dboperation.php may have some mistakes. I saw a video suggesting that I need to decode the array coming from Android first and then use a foreach loop with an Insert inside. However, I'm confused about how to properly use bind params on the decoded array. Do I really need to use them, considering that I should base it on the parameters used in the public function like "public function insertIndividualCart($cartarray){}"? As a beginner, I'm finding it challenging to grasp everything, so any help is truly appreciated!
