Capturing and storing a picture taken with the Camera into a local database / PhoneGap / Cordova / iOS

Question

I'm currently building an app for iOS using Phonegap/Cordova and jQuerymobile. The idea is to take photos with camera and store the captured image for future use. I would like to store the path/filename into my local database and to move the picture file to a persistent place in the iPhone.

Could someone provide me with an example ?

Ok, here is the solution.

• in the Html file

• I have an image tag for displaying the picture taken by the camera :

• I have a button that runs a function for taking photo : Capture Photo

• The function to capture photo is (when the photo is taken, the scr of the 'smallImage' id is populated with the path of the photo)

  function capturePhoto() {
  // Take picture using device camera and retrieve image as base64-encoded string
      navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50 });
  }
  
  //Callback function when the picture has been successfully taken
  function onPhotoDataSuccess(imageData) {                
      // Get image handle
      var smallImage = document.getElementById('smallImage');
  
      // Unhide image elements
      smallImage.style.display = 'block';
      smallImage.src = imageData;
  }
  
  //Callback function when the picture has not been successfully taken
  function onFail(message) {
      alert('Failed to load picture because: ' + message);
  }
  

• Now I want to move the picture in a permanent folder and then save the link into my database :

  function movePic(file){ 
      window.resolveLocalFileSystemURI(file, resolveOnSuccess, resOnError); 
  } 
  
  //Callback function when the file system uri has been resolved
  function resolveOnSuccess(entry){ 
      var d = new Date();
      var n = d.getTime();
      //new file name
      var newFileName = n + ".jpg";
      var myFolderApp = "EasyPacking";
  
      window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSys) {      
      //The folder is created if doesn't exist
      fileSys.root.getDirectory( myFolderApp,
                      {create:true, exclusive: false},
                      function(directory) {
                          entry.moveTo(directory, newFileName,  successMove, resOnError);
                      },
                      resOnError);
                      },
      resOnError);
  }
  
  //Callback function when the file has been moved successfully - inserting the complete path
  function successMove(entry) {
      //I do my insert with "entry.fullPath" as for the path
  }
  
  function resOnError(error) {
      alert(error.code);
  }
  

• My file has been saved in the database to display it, i put "file://" front of the row that contains the image src

Hope this help. J.
