How to retrieve data from Ajax call in Laravel? - php

Question

Now that I got my Ajax call to post the email, I'm still struggling trying to retrieve it, validate it, and insert it to my database.
Here is what I've got :
Controller
public function postSubscribe() {
if(Request::ajax()) {
$data = Input::all();
}
dd(json_decode($data));
// Validation
$validator = Validator::make( Input::only('subscribe_email'),
array(
'subscribe_email' => 'email|unique:subscribes,email',
)
);
if ($validator->fails()) {
return Redirect::to('/#footer')
->with('subscribe_error','This email is already subscribed to us.')
->withErrors($validator)->withInput();
}else{
$subscribe = new Subscribe;
$subscribe->email = Input::get('subscribe_email');
$subscribe->save();
return Redirect::to('/thank-you');
}
}
Route
Route::post('/subscribe','SubscribeController#postSubscribe');
Since that a post request, I don't where can I see my dd(json_decode($data)); ? Am I doing it right ? Please correct me.
Form
{!! Form::open(array('url' => '/subscribe', 'class' => 'subscribe-form', 'role' =>'form')) !!}
<div class="form-group col-lg-7 col-md-8 col-sm-8 col-lg-offset-1">
<label class="sr-only" for="mce-EMAIL">Email address</label>
<input type="email" name="subscribe_email" class="form-control" id="mce-EMAIL" placeholder="Enter email" required>
<!-- real people should not fill this in and expect good things - do not remove this or risk form bot signups-->
<div style="position: absolute; left: -5000px;"><input type="text" name="b_168a366a98d3248fbc35c0b67_73d49e0d23" value=""></div>
</div>
<div class="form-group col-lg-3 col-md-4 col-sm-4">
<button type="button" name="subscribe" class="btn btn-primary btn-block" id="subscribe">Subscribe</button>
</div>
{!! Form::close() !!}
Ajax
<script type="text/javascript">
$(document).ready(function(){
$('#subscribe').click(function(e){
e.preventDefault();
$.ajax({
url: '/subscribe',
type: "post",
data: {'subscribe_email':$('input[name=subscribe_email]').val(), '_token': $('input[name=_token]').val()},
dataType: 'JSON',
success: function (data) {
console.log(data);
} // this is good
});
});
});
</script>
Posting data successfully

thanks to #Pawel Bieszczad
change : dd(json_decode($data));
to : dd(json_encode($data));
and open up console > Network Tab > Response
Now I see my response as expected.
"{"subscribe_email":"bheng#outlook.com","_token":"S3lWmNn6gkkHrYY6nPmupCtrlRqWF6au7b0Mywy7"}"
