It doesn't delete file when clicking Delete photo

It doesn't delete file when clicking Delete photo but only image from preview. How can I make it delete cropped image file.

I send ajax request in cropper.js on click event and delete image may be it will be useful for someone:
.on('click', '.delete-photo', function () {
$.ajax({
method: "POST",
url: '/admin/news/deletephoto',
dataType: "html",
data: {crop : cropper.$thumbnail.attr('src')},
success: function(html){
alert(html);
}
});
cropper.deletePhoto();
})
example of implementation on server side:
if(Yii::$app->request->isAjax) {
$img = $_SERVER['DOCUMENT_ROOT'].$_POST['crop'];
if(file_exists($img)) {
unlink($img);
return "Şəkil müvəfəqiyyətlə silindi";
}
else return "Belə bir şəkil yoxdur";
}
