Laravel saving image in storage - ajax

Question

my code was working fine but now it is not, as image is not saving in folder, i am trying to save image in storage folder, with id as image name.
Controller:
if($request->hasFile('profile_pic')){
if (Input::file('profile_pic')->isValid()) {
$file = Input::file('profile_pic');
$destination = 'storage/app/teachers'.'/';
$ext= $file->getClientOriginalExtension();
$mainFilename = $teacher->id.request()->$ext;
$file->move($destination, $mainFilename.".".'jpg');
echo "uploaded successfully";
}
View: where 0000 is default image.
<div class="row">
<a href="#"> <img id="imgFileUpload" name="profile_pic" src={{asset('storage/app/teachers/'.'0000'.'.jpg')}} value="{{#$teacher->id}}"
onerror="this.src='storage/app/teachers/0000.jpg';" data-toggle="tooltip" data-placement="top" title="click to upload image" class="profile_pic rspimg shadow-sm bg-white rounded" id="imgFileUpload" data-toggle="tooltip" data-placement="top" title="Click To Upload image"></a>
<div class=" col-md-10">
<input type="file" name="profile_pic" id="FileUpload1" style="display: none" />
<span id="spnFilePath"></span>
</div>
</div>
ajax: to preview image in browser.
<script>
$(document).ready(function(){
$(function () {
alert(2);
$("#FileUpload1").change(function () {
var imgControlName = "#imgFileUpload";
readURL(this, imgControlName);
});
function readURL(input, imgControlName) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
$(imgControlName).attr('src', e.target.result);
}
reader.readAsDataURL(input.files[0]);
}
}
var fileupload = $("#FileUpload1");
var image = $("#imgFileUpload");
image.click(function () {
fileupload.click();
});
});
});
</script>

Answer 1

Instead this $destination = 'storage/app/teachers'.'/';
try this $destination = storage_path() . '/app/teachers'.'/';

Answer 2

if ($request->hasFile('profile_pic')) {
$image = $request->file('profile_pic');
$fileName = time() . '.' . $image->getClientOriginalExtension();
$img = Input::make($image->getRealPath());
$img->resize(120, 120, function ($constraint) {
$constraint->aspectRatio();
});
$img->stream(); // <-- Key point
//dd();
Storage::disk('local')->put('/app/teachers'.'/'.$fileName, $img, 'public');
}
try this one
