How to access functions through pug variable?

[philliphartin]

I am porting over existing blade templates to pug.
One of the patterns that is used extensively in the default authentication views bundled with the framework is the use of MessageBags, and a global $errors variable that can be accessed in any view.

I wanted to know how this could be converted into a pug template.

{{-- Show the errors, if any --}}
@if ($errors->any())
    <div class="callout">
        <h4>Errors</h4>
        <ul>
            @foreach($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif

As you can see, it accesses the errors objects, runs the any() method which returns an array of error messages as strings and then loops over the messages and outputs them to a list.

I have tried the following:

    if errors
        .callout
            h4 Errors
            ul
            each error in errors.all()
               li=error

However, it seems I cannot access the all method in this way. Am I doing this incorrectly?

I actually got it working with errors->all(). Is this how I should be accessing it? Seems a bit non-javascript

Since you're still in PHP technically, I would expect to work with the php operator, like you discovered. But this is gonnna be the purview of https://github.com/pug-php/pug, we are a wrapper for that package.

@weotch Makes sense. Thanks for your help!

Hi @pjhartin We did some quick translate from JS syntax to PHP syntax. It's done by this engine: https://github.com/pug-php/js-phpize

In theory, your code with the dot should work. I tested with the following:
https://pug-demo.herokuapp.com/?embed&theme=xcode&border=silver&options-color=rgba(120,120,120,0.5)&engine=pug-php&input=doctype%20html%0Ahtml(lang%3D%22en%22)%0A%20%20body%0A%20%20%20%20each%20val%20in%20zone.getLocation()%0A%20%20%20%20%20%20p%3Dval%0A&vars=array(%0A%20%20%27zone%27%20%3D%3E%20new%20DateTimeZone(%22Europe%2FPrague%22)%2C%0A)

Each with the dot syntax seems to work in this example. Can you try to update to the last versions with composer update? (According to https://pug-demo.herokuapp.com/, it seems to work since the version 2.1.1)
