I am new to angular.So i dont know i am doing it in the right way.I am working in codeigniter along with angular.I need to get the id which i was passing though the angular $http service in my codeigniter controller.. I didn't get any console errors. Simply the data is not returning.. This is my angular controller
app.controller("newsController_id",function($scope,$http,$routeParams){
$http({ method:'POST',
url:'Controller1/get_list_id',
params:{id:$routeParams.id}
})
.then(function (response) {
$scope.blogs_id = response.data;
})
codeigniter controller
public function get_list_id() {
$id=$this->input->post('id');
//$id='6';
$data = $this->Blog_model->getAll_id($id);
$this->output->set_content_type('application/json')->set_output(json_encode($data));
}
There are no errors in the codeigniter model and view pages..since i got my result perfectly when i hardcoded the id value as 6.But no output when i posting the id.help me solving this

Answer 1

you are doing wrong way to pass data angujarjs to codeigniter.
if you want to pass data in POST method pass object in $http service on data section like below
AngularJS Code
$http({
method:'post',
url:'/login',
dataType:"json",
data:{"vEmail":$scope.vEmail,"vPassword":$scope.vPassword},
}).then(function(suc){
console.log(suc);
},function(err){
console.log(err);
});
Codeigniter Code
$vEmail = $this->input->post('vEmail');
$vPassword = $this->input->post('vPassword');
If you want to pass data usgin GET you should be pass data in Param section like below
$http({
method:'get',
url:'/login',
dataType:"json",
params:{"vEmail":$scope.vEmail,"vPassword":$scope.vPassword},
}).then(function(suc){
console.log(suc);
},function(err){
console.log(err);
});
you can get that in codeigniter using get method like below
$this->input->get('vEmail');

Answer 2

You can not get the data by $_POST or $this->input->post , You should have something like this in constructor:
$postdata = file_get_contents("php://input");
$this->request = json_decode($postdata);
Now In controller, you can access the id:
$id = $this->request->id;
But it has a problem, you can't use Codeigniter form validation, because it works with $_POST superglobal. You can do something like this instead (in constructor):
$objectRequest = json_decode( file_get_contents("php://input") );
$this->request = xss_clean( json_decode(json_encode($objectRequest), true) );
$_POST = $this->request;
But this time you can access to id by the following example:
$id = $this->request['id'];

Answer 3

in order to get the post variables from angular you need use the following code
$postdata = file_get_contents("php://input");
$myData = json_decode($postdata);
instead of $id=$this->input->post('id');
so your $id = $myData->id;
Your final code would look like this:
public function get_list_id() {
$postdata = file_get_contents("php://input");
$myData = json_decode($postdata);
$id = $myData->id;
//$id='6';
$data = $this->Blog_model->getAll_id($id);
$this->output->set_content_type('application/json')->set_output(json_encode($data));
}
