json data parameter changes structure upon reaching php server - ios

Question

I'm working on a mobile app that takes personal information from users then saves it to the php server. I'm having a problem on the data with array of dictionaries, how do I fix this?
The sample data that the mobile app sends to the server looks like this, see the work_experience, it's an array of dictionaries:
Don't mind the data values, it's taken on different times, mind the data structure in work_experience
It becomes like this when it reaches the server:
This is how the work_experience gets saved, which is wrong:
This is my post request:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/html"];
[manager POST:SAVE_USER_INFO_URL parameters:_userInformation success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
php function that receives the post request:
$params = $this->params()->fromPost();
$userId = $this->getUsersTable()->saveUserInfo($params);
$this->getSkillsTable()->saveSkills($params['skillset'], $userId);
$this->getWorkExperienceTable()->saveWorkExperience($params['work_experience'], $userId);
$view = new JsonModel($params);
return $view;

Answer 1

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
//manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/html"];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager POST:SAVE_USER_INFO_URL parameters:_userInformation success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
You are limiting the app to only accept responses with header text/html, which is not correct because you are looking for json response. And you need to set the requestSerializer to a AFJSONRequestSerializer instance because the default is AFHTTPRequestSerializer
