I am trying to pass a model object into view and use it in JS, but I can't make it work. It looks broken and throws a syntax error Uncaught SyntaxError: Unexpected token '&' if I just use the variable.
I tried using compact() but this does not work aswell compact(): Argument #1 must be string or array of strings, App\Models\Quiz given
Here is how I return the view with the object:
$result = Quiz::where('id', $quiz_id)->first();
if (!$result['active'] || $result['hidden_by_admin']) {
return abort(404);
}
$result['classic_questions'] = ClassicQuestion::where('quiz_id', $quiz_id)->with('classic_answers')->get();
$result['quiz_tags'] = QuizHasTags::where('quizzes_id', $quiz_id)->with('quiz_tag')->get();
return view('play_quiz')->with('quiz', $result);
Here is how I want to access it in blade.php:
<script>
const quiz = {{ $quiz }};
console_log(quiz);
</script>
Assign your data into the window global object which will make it
available everywhere and you can access it from your JS file:
<ul>
#foreach ($quiz as $quiz_data)
<li> {{ $quiz_data }} </li>
#endforeach
</ul>
<script type="text/javascript">
window.data = {!! json_encode($quiz) !!};
</script>
<script src="...."></script>
// trying to access the model $data from the view.
$(function() {
var values = window.data;
alert(values);
}
You can also send data to view like this:
In controller:
return view('play_quiz', $result);
In view
foreach($quiz_tags as quiz){
//code
}

I´m a beginner starting with Laravel. I´m trying to show a question made on this website.
Here is the Controller page:
public function show($id)
{
//Use the model to get 1 record from the database
$question = $Question::findOrFail($id);
//show the view and pass the record to the view
return view('questions.show')->with('question', $question);
}
I have included at the top of the file:
use App\Question;
Here is my blade page:
#section('content')
<div class="container">
<h1> {{ $question->title }} </h1>
<p class="lead">
{{ $question->description }}
</p>
<hr />
</div>
#endsection
In the model I have not defined anything since I don´t need to specify any special rule. And finally here is the Route:
Route::resource('questions', 'QuestionController');
I got the error "ErrorException Undefined Variable: Question" and supposedly the error is on:
$question = $Question::findOrFail($id);
I´m looking forward to your observations.
Kind Regards.
You just need to change the controller section
public function show($id)
{
//Use the model to get 1 record from the database
$question = Question::findOrFail($id); // here is the error
//show the view and pass the record to the view
return view('questions.show')->with('question', $question);
}
Explanation:- You are going to use a variable $Question that is not defined. This is the basic PHP error, not the laravel issue.
However, You are using the "App\Question" model class not a sperate variable.
I haven't really used this method before and I'm confused where I'm going wrong.
I set the data in the controller, I added the mycourses entry but it's not coming through, everything else is coming in fine
$data['user'] = Auth::user()->load('userType');
$data['courses'] = StudentSchedule::where('instructor_id',Auth::user()->id)
->with('course', 'package.packageCourses', 'user', 'location')->get();
$data['mycourses'] = Course::all();
$data['locations'] = Location::all();
return view('home', $data);
After this I go to the blade and add this
<script>
const user = {!! json_encode($user) !!};
const mycourses = {!! json_encode($mycourses) !!};
const courses = {!! json_encode($courses) !!};
const locations = {!! json_encode($locations) !!};
</script>
Then this goes to the .js, but whats happening there is that its calling the vue
In the vue file I add this to the data()
courses: [],
mycourses: [],
locations: [],
In the vue file I add this to the mounted
this.courses = courses;
this.mycourses = mycourses;
this.locations = locations;
And the mycourses is giving me this error
Error in mounted hook: "ReferenceError: mycourses is not defined"
ReferenceError: mycourses is not defined
I added mycourses after all the other ones were added before, I have everything the same as the courses one and I'm still getting this error. What am I missing?
I'm not sure if this will be helpful or not, meaning perhaps there is a reason this method won't work given your circumstances.
I've found this method of setting/passing data to be pretty helpful. It's less overhead to have to parse in your blade templates (or wherever needed).
Controller
public function myFunction() {
...
$user = Auth::user()->load('userType');
$courses = StudentSchedule::where('instructor_id', $user->id)->with('course', 'package.packageCourses', 'user', 'location')->get();
$mycourses = Course::all();
$locations = Location::all();
// Verify the data is correct.
// dd($courses);
return view('example', compact('user', 'courses', 'mycourses', 'locations');
}
You can verify each is returning the value needed by checking what it's returning using dd().
If you have a vue component you are passing data to that exists in your blade template, you could do something like this to pass the data in as props
example.blade.php
<p>Example content...</p>
<p>Hello, {{ $user->name }}</p>
<example-component :courses="courses" :mycourses="mycourses"></example-component>
<p>...</p>
Now we have passed courses and mycourses to the view component. You can access them there:
<script>
export default {
name: 'ExampleComponet',
data() {
return {
//
}
},
methods: {
//
},
props: {
courses: {
type: Object,
required: true
},
mycourses: {
type: Object,
required: true
},
},
}
</script>
You'll need to update the property type for each of the props you pass in. Perhaps courses isn't an object, but rather a string.
I'm not sure if I've exactly solved your issue, but hope this helps get you in the right direction.
I'm working with my project which get new orders and append to DOM with jQuery.
jQuery
setInterval(function() {
$.ajax({
type:'POST',
url:'{{URL::to('/')}}/orders',
success:function(data)
{
let obj = JSON.parse(data)
let ordersDiv = $('#ordersDiv');
let queueCount = $('#queueCount');
queueCount.html(obj.count);
ordersDiv.html(obj.data);
}
});
}, 15000);
Controller
//some code here
$data .= "<a class=\"example-image-link\"
href=\"{{URL::to('/')}}/users/uploads/profiles/{{strlen($biker-
>picture_file_path)>0?$biker>picture_file_path:'avatar.png'}}\">
<img src=\"URL::to('/')/users/uploads/profiles/$biker-
>picture_file_path:.'avatar.png'\" data-toggle=\"tooltip\"
title=\"HiBes Biker\">
</a>";
//more code here
My problem is that I'm getting this result:
<a href=\"{URL::to('\/')}\/order-details\/3159\">Details<\/a>
I expect a result something like this:
<a href=\"http://127.0.0.1:8000/order-details\/3159\">Details<\/a>
The reason your URLs still contain the placeholders is you are building HTML in your controller, not your view.
Ideally, you should switch this logic into the view, where the {{ $var }} syntax will work.
Create a new blade file bikerimage.blade.php
#foreach($bikers as $biker)
<a class="example-image-link"
href="{{URL::to('/')}}/users/uploads/profiles/{{ $biker->picture_file_path ?: 'avatar.png' }}">
<img src="{{ URL::to('/')}}/users/uploads/profiles/{{ $biker->picture_file_path ?: 'avatar.png' }}"
data-toggle="tooltip"
title="HiBes Biker"
>
</a>
#endforeach
Then in your controller, you can do something like
//some code here
$data = view('partials/bikerimage.blade.php', ['bikers' => $bikers])->render();
return [
'html' => $data,
];
This means you can still return the data as part of an ajax call, without having to build HTML in your controller.
I try to build a post/get method with an list group team / href. Here is my code...
#if(count($variableController) > 0)
<ul class="list-group">
#foreach($variableController as $variableView)
{{$variableView->heimmannschaft}}
#endforeach
</ul>
#endif
spielerAuswahl is my view. And after a click on the list-group-item I get to this view. But there I need the information from the list-group-item.
Route::post('/spielerAuswahl', function () {
return 123;
//var_dump($_POST)
});
What I have to do?
replcae post with get method like this:
Route::get('/spielerAuswahl', function () {
return 123;
//var_dump($_POST)
});
if you want to return spielerAuswahl as view
Route::get('/spielerAuswahl', function () {
return view('spielerAuswahl');
});
dont forget
spielerAuswahl.blade.php should be in reousrces/view directory
on the other hand if you want to send some data to view
change route to :
Route::get('/spielerAuswahl/{somevar}', function ($somevar) {
return view('spielerAuswahl',compact('somevar'));
});
and send data like this:
#if(count($variableController) > 0)
<ul class="list-group">
#foreach($variableController as $variableView)
{{$variableView->heimmannschaft}}
#endforeach
</ul>
#endif
it was get method
if you want to use post method your action method should be POST
one way is using <form action="" method="post">
I'm bit stuck at a place. I've got some views of small HTML sections which when combined gives the complete HTML page. I'm trying to build a website builder with Jquery, where I'm having a drop event which adds those particular views:
For example I've got HTML for slideshow:
<div id="slideshow" data-nitsid="2">
<div class="revolution-slider">
<ul>
<!-- SLIDE -->
#foreach($contents->slider as $sliders)
<li data-transition="{{ $sliders->transition }}" data-slotamount="{{ $sliders->slotamount }}" data-masterspeed="{{ $sliders->masterspeed }}">
<!-- MAIN IMAGE -->
<img src="{{ URL::asset($sliders->url) }}" alt="">
</li>
#endforeach
</ul>
</div>
</div>
In my JQuery code:
nitsbuilder.dropeventhandler = function ($item, $position) {
var nits_id = $item.data('nitsid');
$.ajax({
method: 'POST',
url: dropurl,
data: { nits_id: nits_id, _token: token},
dataType: 'json',
success: function (data) {
nitsbuilder.adder($item, $position, data);
}
});
}
Before I was having html codes in the database so it was easier to pull out the html and add to the HTML page, now I'm having html in views, how can I push/include this HTML code or view to ajax request so that my nitsbuilder.adder function executes placing the view through my controller.
My present Controller is:
class DropeventController extends Controller
{
public function htmlcode(Request $request)
{
$pluginid = $request['nits_id'];
$code = Plugins::findOrFail($pluginid);
$htmlcode = $code->code;
return response()->json(['htmlcode' => $htmlcode]);
}
}
Please guide me. Thanks
You can easily create html strings from blade views using \View::make
e.g. let's assume you have the following folder strucutre
project
...
ressources
views
snippets
snippetA
snippetB
You could now create a route / controller accepting a "name" parameter and then do the following
$name = "snippetA"; // get this from parameters
$html = \View::make("snippets.$name")->render();
You might need to also add variables depending on your views
$name = "snippetA"; // get this from parameters
$errors = []; // error variable might be needed
$html = \View::make("snippets.$name", compact('errors'))->render();
You can then return this html string
return ['html' => $html];
And access it from your ajax done function.
I hope this helps
Suppose your html is in view file called abc.blade.php, you can return the rendered view from your controller in json.
return response()->json([
'htmlcode' => View::make('abc')->render();
]);
