I created a simple submit page using codeigniter and angular.js. How can I throw HTTP status codes after somebody clicked submit button, so the the user will know if it is successful or not, or any other reason why it failed?
BTW, I base my code in this post Codeigniter + Angular Js: How to receive JSON data
Don't use .success() IMHO. Use .then() instead.
.then(function(resp){
var $status = resp.status //http status code
var $data = resp.data //data back from the server
});
If you're set on using success, then check out all the arguments for the success function:
success(function(data, status, headers, config)
As usual, check the docs when you'er in doubt
then() instead of success()!
status in the above indicates the response from the server, Here's a list of those codes. You can return your own response with custom text by simply returning a json encoded array, as such: echo json_encode(array('status' => 'OK', 'msg' => 'it went ok!'));. Then in your angular you can access this like: resp.data.status.then() instead of .success() is due to the fact that a promise is returned from the $http call which can allow you to chain methods against it. In this particular case, it's a non issue, but in practice, it will be better as you'll be used to it for more complex tasks.
