Answer 1

map the response before subscribing
this.http.post(url, body, options)
.map((res:Response) => res.json());
.subscribe((data) =>
{
if(data.status === 200)
{
this.hideForm = true;
this.sendNotification(console.log(data.meesage));
}
});

Answer 2

Php code
$sql = "INSERT INTO eastcost_school_room(school_room_name, created) VALUES(:name, Now())";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':name', $name, PDO::PARAM_STR);
$stmt->execute();
$response["success"] = 1;
$response["message"] = 'Congratulations the record ' . $name . ' was added to the database';
// echoing JSON response
echo json_encode($response);
Post method in the api service class
Service
insert(parameters): Observable<any> {
return this.http.post('url', body, {
headers: headers
})
.map((res: any) => res.json())
}
And subscribe the response from your class
this.service.insert(parameters)
.subscribe(
response => {
console.log(response);
if (response.success == "1") {
console.log("Successfull login");
}
else {
alert(" Invalid user");
}
},
error => {
alert(error);
}
);
