    <p>I have been trying to make this work, searched google and here since Friday. My ultimate goal is to be able take multiple pictures with a title and description for each and upload them to a server, then display on a web page.</p> <p>What I have so far is: the ability to give one image a title and description, browse the gallery, find an image and select it. BUT when I do the image is uploaded along with the form, immediately. I would like to be able to do this using a submit button.</p> <p>I also have a button to take an image instead, and a preview of the image on the page appears. BUT when I do take an image with the camera I do not know how to upload my form. I was able to print to the screen the image data using a div and innerHTML call... but honestly i'm so lost and do not even know where to start posting specific snippets of code. I will post the entire page as it currently exists right now....</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;File Transfer Example&lt;/title&gt; &lt;script type="text/javascript" charset="utf-8" src="cordova-2.3.0.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" charset="utf-8"&gt; var pictureSource; // picture source var destinationType; // sets the format of returned value // Wait for Cordova to load // document.addEventListener("deviceready", onDeviceReady, false); // Cordova is ready // function onDeviceReady() { pictureSource=navigator.camera.PictureSourceType; destinationType=navigator.camera.DestinationType; } function browse(){ navigator.camera.getPicture(uploadPhoto, function(message) { alert('get picture failed'); }, { quality: 50, destinationType: navigator.camera.DestinationType.FILE_URI, sourceType: navigator.camera.PictureSourceType.PHOTOLIBRARY } ); } function uploadPhoto(imageURI) { var options = new FileUploadOptions(); options.fileKey="file"; options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1); options.mimeType="image/jpeg"; var params = {}; params.value1 = "test"; params.value2 = document.getElementById('file_name').value + ""; params.value3 = document.getElementById('file_description').value + ""; options.params = params; var ft = new FileTransfer(); ft.upload(imageURI, encodeURI("http://site.com/pages/upload.php"), win, fail, options); } function win(r) { console.log("Code = " + r.responseCode); console.log("Response = " + r.response); console.log("Sent = " + r.bytesSent); } function onFileSystemSuccess(fileSystem) { console.log(fileSystem.name); } function onResolveSuccess(fileEntry) { console.log(fileEntry.name); } function fail(evt) { console.log(evt.target.error.code); } function fail(error) { alert("An error has occurred: Code = " + error.code); console.log("upload error source " + error.source); console.log("upload error target " + error.target); } function capturePhoto() { // Take picture using device camera, allow edit, and retrieve image as base64-encoded string navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 20, allowEdit: true, destinationType: destinationType.DATA_URL }); } function onPhotoDataSuccess(imageData) { // console.log(imageData); var smallImage = document.getElementById('smallImage'); smallImage.style.display = 'block'; smallImage.src = "data:image/jpeg;base64," + imageData; var smallTEXT = document.getElementById('smallTEXT'); smallTEXT.style.display = 'block'; smallTEXT.innerHTML = "data:image/jpeg;base64," + imageData; } function onPhotoURISuccess(imageURI) { // Uncomment to view the image file URI // console.log(imageURI); // Get image handle // var largeImage = document.getElementById('largeImage'); // Unhide image elements // largeImage.style.display = 'block'; largeImage.src = imageURI; } function capturePhoto() { // Take picture using device camera and retrieve image as base64-encoded string navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50, destinationType: destinationType.DATA_URL }); } // Called if something bad happens. // function onFail(message) { alert('Failed because: ' + message); } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; </code></pre> <p><br></p> <pre><code> &lt;h1&gt;Example&lt;/h1&gt; &lt;p&gt;Upload File&lt;/p&gt; &lt;form name ="filename" id="file_name_form" action="#"&gt; Title &lt;br&gt;&lt;input type="text" name="name" id="file_name" /&gt;&lt;br&gt; Description &lt;br&gt;&lt;textarea type="text" name="description" id="file_description" /&gt;&lt;/textarea&gt; &lt;/form&gt; &lt;button onclick="capturePhoto();"&gt;Use Camera&lt;/button&gt; &lt;br&gt; &lt;button onclick="browse();"&gt;browse gallery&lt;/button&gt;&lt;br&gt; &lt;img style="display:none;width:160px;" id="smallImage" src="" /&gt; &lt;hr&gt; &lt;div id="smallTEXT"&gt;ggg&lt;/div&gt; &lt;button onclick"uploadPhoto();"&gt;submit&lt;/button&gt; &lt;/body&gt; </code></pre> <p></p>

    1. COYour browse method calls uploadPhoto so it is working the way it should. The call to Camera.getPicture can't select multiple photos if that is what you are after.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
