title: Upload image to server path using AngularJS and PHP
body: <p>As the question mentioned, I have a question regarding how to upload image to server. I have searched through the internet and found some reference but I still don't understand as how they work. For example: <a href="https://stackoverflow.com/questions/23807177/angularjs-image-upload-using-php">AngularJS Image upload using php</a></p>
  
  <p>How is the image being uploaded? As there are no submit button there. I have followed the code there and tried it, still can't upload the files. </p>
  
  <p>I have also tried to see some available modules from here :<a href="https://stackoverflow.com/questions/18571001/file-upload-using-angularjs">File Upload using AngularJS</a>
  After looking for couple of hours, I still don't understand how to use them. Is there any simpler or easier understand guides for me to follow? Thanks in advance. </p>
  
  <p>Edit: If there are simpler example like just upload one file, please link me to it as there are many examples that are quite advance which consist of many parts such as upload multiple file etc.  </p>
