Laravel 5 hash changes every time with Ajax call - ajax

Question

the following is the modal which is invoked on button click
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="myModalLabel">Compose New Task</h4>
</div>
<div class="modal-body db">
<div class="form-group db">
<label class="col-sm-6 control-label">Current Password </label>
<div class="col-sm-6">
<input type="password" id="current_password" class="form-control">
</div>
</div>
<div class="form-group">
<label class="col-sm-6 control-label">New Password </label>
<div class="col-sm-6">
<input type="password" id="new_password" class="form-control">
<input type="hidden" value="{{ csrf_token() }}" id="csrftoken">
</div>
</div>
<div class="form-group">
<div class="error" id="message"></div>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary" id="updatePassword">Save changes</button>
</div>
</div>
</div>
Relevant line in the above code is number 11
$("#updatePassword").click(function () {
var current_password = document.getElementById('current_password').value;
var new_password = document.getElementById('new_password').value;
var token = document.getElementById('csrftoken').value;
$.post('/modalupdatePassword', {'current_password': current_password, 'new_password': new_password, '_token': token}, function (data) {
var parsed = JSON.parse(data);
console.log(parsed);
$('#message').append(parsed);
});
});
and this is my modalPasswordUpdate function
public function modalUpdate(Request $request)
{
$current_password = bcrypt($request->current_password);
$updateRequest = User::where('id', Auth::user()->id)
->where('password', $current_password)
->first();
echo json_encode($current_password);
}
Now every time I send the request I am getting different hash
following is my updated code
Route::get('check', function()
{
echo $password = Hash::make('secret');
});
this also returns new password everytime

You are sending your request via post. Laravel documentation states, that the VerifyCsrfToken middleware will look for X-CSRF-TOKEN request headers during post requests, so do try the following.
Add the token to a meta tag in the head of your document.
<meta name="csrf-token" content="{{ csrf_token() }}" />
Now add the X-CSRF-TOKEN as a header to the global ajax settings like so
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
Now all AJAX requests will automatically include the CSRF token.
You can read more about this on the Laravel docs right here.
