I am trying to upload an img from an android phone to a php server.
But when it is uploaded its data is lost(the file exist but has 0 bytes)
I dont know if the problem is on the php side or the android side.
Here is the code I use uploadenter code here
<?php
error_reporting(E_ALL);
if(isset($_POST['ImageName'])){
$imgname = $_POST['ImageName'];
$imsrc = base64_decode($_POST['base64']);
$fp = fopen($imgname, 'w');
fwrite($fp, $imsrc);
if(fclose($fp)){
echo "Image uploaded";
}else{
echo "Error uploading image";
}
}
?>
I am not getting any errors anywhere
