When we want to upload a image in on server in cordova/ionic some time we need to convert the image in base64 formate . I've write a function which will convert your image in base64.
function convertImgToBase64URL(url, callback, outputFormat) {
var img = new Image();
img.crossOrigin = 'Anonymous';
img.onload = function() {
var canvas = document.createElement('CANVAS'),
ctx = canvas.getContext('2d'),
dataURL;
canvas.height = this.height;
canvas.width = this.width;
ctx.drawImage(this, 0, 0);
dataURL = canvas.toDataURL(outputFormat);
callback(dataURL);
canvas = null;
};
img.src = url;
return url;
}
convertImgToBase64URL(img, function(base64Img) {
console.log(base64Img);// this is your base64 converted image
});
$http.post(server_url,[base64Img])
$params = json_decode(file_get_contents('php://input'), true); get the post image
$img = imageUploadByBase64($params[0]);// this is the saved image path with image name
function imageUploadByBase64($img) {
$randomImgName = date('Y-m-d_H-i-s').'_'.rand(0, 6000).'.png';
$image = base64_to_jpeg($img, 'uploads/' . $randomImgName);// you need to create a directory withh name 'uploads'
return $image;
}
function base64_to_jpeg($base64_string, $output_file) {
$ifp = fopen($output_file, "wb");
$data = explode(',', $base64_string);
fwrite($ifp, base64_decode($data[1]));
fclose($ifp);
return $output_file;
}
