Laravel Blade passing variable with string through @include causes error

Question

In Laravel 5.0.27 I am including a view with with a variable and the following code:

@include('layouts.article', [
        'mainTitle' => "404, page not found",
        'mainContent' => "sorry, but the requested page does not exist :("
    ])

and I get the following error...

FatalErrorException syntax ... error, unexpected ','

I've narrowed down that the error is solely from the "(" in the "mainContent" variable string, and when I remove the "(" the error disappears and everything runs fine. I can't find anything in documentation on this or any similar errors listed online.

Does anyone know if this is expected behavior or if this is a bug that should be reported?

Thanks so much for your time!

Solution 1

It's not a bug but a limitation of blade syntax due to regex. Solution came from github:

The problem is using multi-line. You can only use a single line to [pass variables] in Blade, since syntax is limited [by regular expressions]

Try the code below and you should be good to go:

@include('layouts.article', ['mainTitle' => "404, page not found", 'mainContent' => "sorry, but the requested page does not exist :("])

Solution 2

You can pass a $data array

<?php $data=[
        'mainTitle' => "404, page not found",
        'mainContent' => "sorry, but the requested page does not exist :("
    ]  ?>
@include('layouts.article', $data)

use $data['mainTitle'] etc in layouts.article

Solution 3

In 5.8v, included views inherit all variables from the parent as per in documentation:

Even though the included view will inherit all data available in the parent view, you may also pass an array of extra data to the included view:

@include('view.name', ['some' => 'data'])

The limitation seems to be lifted with Laravel 5.6: cloud.mxchange.org/s/149vSQYmDeENiuY/…

Don't know why people are down-voting it!

I can not see reason either

I downvoted this answer because it doesn't address the actual question. The premise of the question is that include breaks with a specific variable inclusion and format, see my github issue for an understanding of it: github.com/laravel/framework/issues/8502

The issue claims as of 5.6 it still doesn't work but should soon, no update on that issue though if it was implemented github.com/laravel/framework/issues/8502

Hi, is it possible to attach some kind of @only keyword to this, to restrict access to the included context? I'm asking in relation to the 'only' keyword in twig
