What I am trying to do is update my MySQL database from the result of an ajax call to a remote website and then use those results to update my own database.
After building the JSON object by looping the result set using the PUSH method I console.log the result and get this :
[]
0: {id: "3340", orderID: "1518883", status: "Shipped", shipdate: "March 12, 2020", shipfrom: "USA", …}
1: {id: "1441", orderID: "1518884", status: "Scheduled", shipdate: "March 19, 2020", shipfrom: "USA", …}
2: {id: "3345", orderID: "1518895", status: "Shipped", shipdate: "March 12, 2020", shipfrom: "IA", …}
3: {id: "3342", orderID: "1518886", status: "Shipped", shipdate: "March 11, 2020", shipfrom: "TX", …}
4: {id: "3346", orderID: "1518896", status: "Shipped", shipdate: "March 12, 2020", shipfrom: "MN", …}
5: {id: "3343", orderID: "1518892", status: "Finishing", shipdate: "March 16, 2020", shipfrom: "IA", …}
6: {id: "3344", orderID: "1518893", status: "Shipped", shipdate: "March 12, 2020", shipfrom: "IA", …}
7: {id: "60", orderID: "1518887", status: "Shipped", shipdate: "March 12, 2020", shipfrom: "IA", …}
8: {id: "2149", orderID: "1518888", status: "Shipped", shipdate: "March 12, 2020", shipfrom: "NV", …}
9: {id: "2149", orderID: "1518894", status: "Shipped", shipdate: "March 12, 2020", shipfrom: "NV", …}
length: 10
__proto__: Array(0)
When I ajax it to PHP and var_dump it I get Array(0){}. I have tried many ways from other peoples questions on this site with similar problems and this is the best result I have got, most results with other methods result in null or nothing at all.
I suspect it is all in the way I am constructing the JSON by using variables. Here is the code I am using in js. When I paste the console result to lint I get errors. I have tried sending test data to the php and get a result so I am fairly certain it is in the way I am preparing the JSON data.
$('#btnUpdate').on('click',
function() {
var jsonData = new Array();
var oTable = $("#example").DataTable();
oTable.rows().every(function (index, element) {
// get tracking data
var tableData = this.data();
var gNum="https://tracking.xyz.com/api/?key=b39f008e318efd2bb988d724a161b61c6909677f&order="+tableData[4];
$.ajax({
url: gNum,
dataType: 'json',
}).done(function(data) {
var data = JSON.stringify(data)
var mydata=(JSON.parse(data));
console.log(mydata);
if(mydata.order_info){
if(mydata.order_info.tracking){
jsObject = {
"id": tableData[1],
"orderID" : tableData[2],
"status": mydata.order_info.status,
"shipdate": mydata.order_info.ship_date,
"shipfrom": mydata.order_info.ship_from,
"track" : mydata.order_info.tracking.number,
"carrier": mydata.order_info.tracking.carrier
}
}else{
jsObject = {
"id": tableData[1],
"orderID" : tableData[2],
"status": mydata.order_info.status,
"shipdate": mydata.order_info.ship_date,
"shipfrom": mydata.order_info.ship_from,
"track" : "",
"carrier": ""
};
};
JSON.stringify(jsObject);
jsonData.push(jsObject);
}else{
alert('not found');
};
});
});
console.log(jsonData)
//var testData = new Array();
//var record1 = {"var1":"9","var2":"16","var3":"16"};
//var record2 = {"var4":"8","var5":"15","var6":"15"};
//testData.push(record1);
//testData.push(record2);
// send data to server to update records
$.ajax({
type: 'POST',
url: 'statusUpdate.php/',
data: {'data': JSON.stringify(jsonData)},
ContentType: 'application/x-www-form-urlencoded; charset=UTF-8',
success: function(data) {
alert(data);
}
});
PHP Code
<?php
$json= $_POST['data'];
$array = json_decode( $json, true );
var_dump($array);
//exit;
// getting no usable result so code below is not processed
foreach ($array as $key => $jsons) { // This will search in the 2 jsons
foreach($jsons as $key => $value) {
if($key == 'id') $id = $value;
if($key == 'orderID') $orderID = $value;
if($key == 'status') $status = $value;
if($key == 'shipdate') $shipdate = $value;
if($key == 'shipfrom') $shipfrom = $value;
if($key == 'track') $track = $value;
if($key == 'carrier') $carrier = $value;
$sql = "UPDATE Orders SET OrderStatus=" .$status. " shippedDate=" .$shipdate. " ShippedFrom =" .$shipfrom. " TrackingNumber = " .$track. " shippedVia =" .$carrier. " WHERE customer_id = " .$id. " AND OrderNumber = " . $orderID ;
//if (!mysqli_query($con,$sql)) {
// echo("Error description: " . mysqli_error($con));
//}
}
}
echo $id;
//database connection close
mysqli_close($con);
?>
Update
When I send hard coded test data the response is good so this is definitely an issue with the data collected from the previous ajax. I read somewhere that the result of an ajax call is a reference to the data result and not the actual result itself. I don't know if that is true but for certain I cannot pass the data in an array either made as JSON or as a single JavaScript array.
I have tried both ways and the data is always empty on the server side except when I use the test data which is hard coded and not the result of an ajax request. I think I need to approach this problem in a whole other way, probably using curl on the server PHP side.
var testData = new Array();
var record1 = {"var1":"9","var2":"16","var3":"16"};
var record2 = {"var4":"8","var5":"15","var6":"15"};
testData.push(record1);
testData.push(record2);
// send data to server to update records
$.ajax({
type: 'POST',
url: 'statusUpdate.php',
//dataType: 'json',
data: {'data' : testData},
//ContentType: 'application/json',
success: function(data) {
console.log(data);
}
});
