App for registering for an AngularJS course

Currently, I am developing an application that involves a JSON list containing information about various courses such as title, course ID, location, and type.

One of the features in my app includes a modal window that appears when a user clicks on a specific course to confirm their registration. This modal sends the registration details to a PHP file, which then returns feedback in JSON format regarding the successful registration.

I have encountered a hurdle at this stage as AngularJS seems unable to retrieve the returned information. Although I can see the data from the PHP file using console.log(), attempting to display certain parts of it on the page results in an "undefined" error.

Additionally, I am seeking a solution to hide the registration button for users who have already registered for certain courses. How should I go about implementing this functionality?

Does anyone have a similar example or experience they could share?

Answer №1

It seems like you might be facing an issue where the data is being accessed before the callback has completed. The reason why you see the data in the console is because it gets resolved at a later point. Make sure to have a callback function or return a promise when fetching/sending the data. If you're manipulating data in JavaScript, ensure that all operations are done within the callback or using 

$promise.$then(function() {/*stuff here*/});
