Upload photos from iPhone to PHP using PhoneGap

I have a simple upload form that works in PHP (works on the network), and I can also capture a photo from iPhone using PhoneGap (base64) and display it on the device.

But I can’t figure out how to upload it to my server using PHP.

Here the code works in PHP:

index.php

<?
//print_r($_POST);

if($_POST["action"] == "Upload Image")
{
unset($imagename);

if(!isset($_FILES) && isset($HTTP_POST_FILES))
$_FILES = $HTTP_POST_FILES;

if(!isset($_FILES['image_file']))
$error["image_file"] = "An image was not found.";


$imagename = basename($_FILES['image_file']['name']);
//echo $imagename;

if(empty($imagename))
$error["imagename"] = "The name of the image was not found.";

if(empty($error))
{
$newimage = "images/" . $imagename;
//echo $newimage;
$result = @move_uploaded_file($_FILES['image_file']['tmp_name'], $newimage);
if(empty($result))
$error["result"] = "There was an error moving the uploaded file.";
}

}

include("upload_form.php");

if(is_array($error))
{
while(list($key, $val) = each($error))
{
echo $val;
echo "<br>\n";
}
}

include("list_images.php");

?>

And two of them include ...

UPLOAD_FORM.PHP

<form method="POST" enctype="multipart/form-data" name="image_upload_form" action="<?$_SERVER["PHP_SELF"];?>">
<p><input type="file" name="image_file" size="20" value="beautiful.jpg"></p>
<p><input type="submit" value="Upload Image" name="action"></p>
</form>

LIST_IMAGES.PHP

<?
$handle = @opendir("images");

if(!empty($handle))
{
while(false !== ($file = readdir($handle)))
{
if(is_file("images/" . $file))
echo '<img src="images/' . $file . '"><br><br>';
}
}

closedir($handle);
?>

Here's the code running on iPhone 4 (iOS 4.2) in PhoneGap

INDEX.HTML (works in the WWW directory in PhoneGap)

    function getPicture(sourceType)
    {

        if (sourceType != undefined) {
            options["sourceType"] = sourceType;

        }
        // if no sourceType specified, the default is CAMERA 
        navigator.camera.getPicture(getPicture_Success, null, options);
    };

    function getPicture_Success(imageData)
    {
            //alert("getpic success");
            document.getElementById("test_img").src = "data:image/jpeg;base64," + imageData;


    }   



    </script>
  </head>
  <body onload="onBodyLoad()" marginheight=0 marginwidth=0 leftmargin=0 topmargin=0>



            <h1>Camera</h1>

            <img style="width:80px;height:120px" id="test_img" src="" /> 

            <p>

            <!-- for testing, add the buttons below -->

            <button onclick="getPicture()">From Camera</button>

            <p>



            <button onclick="getPicture(PictureSourceType.PHOTO_LIBRARY)">From Photo Library</button>




  </body>
</html>
</html>

By the way, while I can capture a fresh picture from the device’s camera, I was completely unable to get the images from the library ... if anyone knows how to do this, I will also be grateful for the feedback.

Can I upload photos from PhoneGap / iPhone to PHP? Any source code on either side of this will be a GREAT rating.

In a telephone bundle:

$.post(URLReport,{   
   pic1: document.getElementById("image1").src.slice(23),
 }, function(xml) {  
     //stuff to do on success
 });

On server:

if (isset($_POST['pic1'])) {
  $pic = base64_decode( $_POST['pic1']);
  if (strlen($pic) > 9 ) {
    $fh = fopen(yourfilename, 'w') or die("can't open file");
    fwrite($fh, $pic);
    fclose($fh);
  }
}

Easy peasy.
