Var emptied from child view to parent view Laravel - php

Question

I got a really strange behavior in my views. I have a parent view called "access.blade.php" and child view "survey.blade.php".
I instanciated 2 vars in the parent view which are empty arrays.
I populate them in the child view but when i var_dump them in the parent view after the include of the child view, my var are empty...
here is the parent view :
#extends('template')
#section('title')
Compile result
#stop
#section('content')
<div id="access" class="container-fluid main-content">
<div class="row">
<div class="col-xs-6 col-md-push-3 col-xs-push-3">
<div class="page-title white-text text-center">
<h1>Access Report</h1>
</div>
<div class="widget-container fluid-height clearfix">
<?php
$session = Sessions::find($params['session_id']);
$userNotSeen = [];
$userSeen = [];
?>
<div class="heading">
<button class="btn btn-success btn-xl pull-right" role="button" data-toggle="modal" data-target="#complianceModal">Compliance</button>
Access Report for
{{ isset($result->content->display_name) ? $result->content->display_name : $result->content->title }}
<p>
Journey: {{ $session->location_id != null ? $session->location->city : $session->place }}
</p>
</div>
<div class="row text-center"></div>
<div class="row">
<div class="col-sm-offset-1 col-sm-10">
#if($result != null)
#if($result->content_type == 1)
#include('contents.partials.access.tasklist')
#elseif($result->content_type == 2)
#include('contents.partials.access.resources')
#elseif($result->content_type == 3)
#include('contents.partials.access.survey')
#elseif($result->content_type == 4)
#include('contents.partials.access.feedback')
#elseif($result->content_type == 5)
#include('contents.partials.access.memo')
#elseif($result->content_type == 6)
#include('contents.partials.access.gear')
#elseif($result->content_type == 7)
#include('contents.partials.access.sinsim')
#elseif($result->content_type == 8)
#include('contents.partials.access.changr')
#endif
#else
<p class="text-center">{{ $errors }}</p>
#endif
<pre>
{{ var_dump($userNotSeen) }}
</pre>
<pre>
{{ var_dump($userSeen) }}
</pre>
</div>
</div>
</div>
</div>
</div>
</div>
#include('contents.partials.modal')
#stop
And here is my child view
<table class="table">
<thead>
<tr>
<th>Name</th>
<th class="text-center">Viewed</th>
<th class="text-center">Submitted</th>
<th class="text-center">Personnal Results</th>
</tr>
</thead>
<tbody>
#if(isset($result->data))
#forelse($result->data as $key => $value)
<tr {{ $value->view == 0 ? 'class="notyetseen"' : ''; }}>
<td>{{ $value->fullname }}</td>
<td class="text-center">{{ $value->view == 0 ? 'No' : 'Yes' }}</td>
<td class="text-center">{{ $value->done == 0 ? 'No' : 'Yes' }}</td>
<td class="text-center">
Get results
</td>
</tr>
<?php
if($value->view == 0) {
array_push($userNotSeen, $key);
} else {
array_push($userSeen, $key);
}
?>
#empty
<tr><td colspan="3" class="text-center">{{ $errors }}</td></tr>
#endforelse
#else
<tr><td colspan="3" class="text-center">No participants for this journey</td></tr>
#endif
</tbody>
</table>
I have an idea about the why it doesn't work: maybe the parent view is loaded completly before the child view, so my var are not yet populated.
If it is the case, is there any solution?

Answer 1

First of all, never EVER include logic in your templates. Move this logic to your controller and pass results to a view. Templates are only for displaying your data.
If you have to use <?php in your Blade template, you are doing something wrong.
Second, Blade compiles your templates separately. It is not a simple include(__child_template__). That's why while compiling each of your templates, Blade works with completely different variable scopes and $userNotSeen in access.blade.php template is not the same as in your survey.blade.php.
