slimphp / twig-view Goto Github PK

From documentation:

// Define named route
$app->get('/hello/{name}', function ($request, $response, $args) {
    $this['view']->render('profile.html', [
        'name' => $args['name']
    ]);
})->setName('profile');

but i give error because i not pass the response object with first param to render method, so i edited with this:

// Define named route
$app->get('/hello/{name}', function ($request, $response, $args) {
    return $this['view']->render($response, 'profile.html', [
        'name' => $args['name']
    ]);
})->setName('profile');

Added the return because the router waiting the response object and in reference to this issue #8 I edited with this:

public function render(ResponseInterface $response, $template, array $data = [])
    {
        $response->getBody()->write($this->fetch($template, $data));
        return $response;
    }

Anyone have the same error? Ofc I use the latest dev version of slim.

With this modifications all working correctly.

The instructions for this repo dont seem to work for me
I installed the Slim Framework from the home and documentation which works fine first time.
Yet when i install Twig View i get many application inconsistancies such as file class names not available.

and Searching your repo is seems Slim\App doesnt even exist?

Just ran into an odd issue where a response was being preserved by reference, though I'm still not certain how.

Think I narrowed this down to the slim/twig-view rendering method:

/**
 * Output rendered template
 *
 * @param ResponseInterface $response
 * @param  string $template Template pathname relative to templates directory
 * @param  array $data Associative array of template variables
 * @return ResponseInterface
 */
public function render(ResponseInterface $response, $template, $data = [])
{
     $response->getBody()->write($this->fetch($template, $data));

     return $response;
}

Question: shouldn't this be preserving the immutability of the response? ie. $response = $response->...

Or is it something related to the Twig Environment?

Or is it the write method from Slim that's breaking things (by returning the response, rather than a clone / new one)?

Thanks for any insight you can provide. XD

So, I realize that this has been discussed before in #20 and also in slimphp/Slim#1326, but it seem this has not really been resolved.

Let me explain the problem again

1. Sometimes I need a fully qualified URL to a named route. Simplest example: I'm using twig to build the email body for an account activation mail. Let's say I have a route named activate with a parameter token
2. My application runs in a sub directory of the web server. Let's say /app

So here are my options:

1. {{ path_for('activation', {token: 'foo'}) }} -> /app/activation/foo
2. {{ base_url() }} -> http://example.com/app

As you can see, I can not simply combine the two to create an absolute URL, since the initial directory would be duplicated. Ideally I would have a url_for() method that works exactly like path_for but returns a fully qualified URL.

This issue is similar to slimphp/Slim#2762.

With the solution proposed in slimphp/Slim#2762 (comment), a user could for example just write

$app = AppFactory::create();
$app->addRoutingMiddleware();
$app->addErrorMiddleware(true, true, false)
    ->getDefaultErrorHandler()->forceContentType('application/json');

and only AppFactory needs to be imported. That is pretty nice for these two internal slim middlewares.

I wonder if we could simplify the other middlewares as well. I mean, for example, to add the twig middleware, a user has to write the following code.

$container = new Container();
AppFactory::setContainer($container);

$app = AppFactory::create();
// Let's add the routing middleware. Nice.
$app->addRoutingMiddleware();

// Let's add the twig middleware. Complicated.
$app->add(new TwigMiddleware(
    new Twig(__DIR__ . '/../templates', [
        'cache' => __DIR__ . '/../cache/twig',
        'auto_reload' => true,
    ]),
    $app->getContainer(),
    $app->getRouteCollector()->getRouteParser(),
    '',
    Twig::class
));

// Let's add the error middleware. Nice.
$app->addErrorMiddleware(true, true, false);

We could for example let the user add twig to the container and then he/she can simply call

$app->add(TwigMiddleware::create($app, $basePath, $twigContainerKey));

The static create() method would then get the container from the app, twig from the container, and the route parser from the app (via route collector). Of course, the method would throw exceptions whenever anything is missing (no container, twig not found, etc.).

What is the best way of coupling this with flash messages?

Currently, I want to do this:

$app->get('/flash', function ($request, $response, $args) use ($app) {
    $this->flash->addMessage('flash', 'This is a message');
    return $response->withStatus(302)->withHeader('Location', '/');
});

$app->get('/', function ($request, $response, $args) use ($app) {
    $flashes= $this->flash->getMessages();  
    return $this->view->render($response, 'home.php', [
        'messages' => $flashes
    ]);
})->setName('home');

And then:
{% for flash in messages %}
{{ flash }}
{% endfor %}

However, I am getting an error:
Notice: Array to string conversion in ... /vendor/twig/twig/lib/Twig/Environment.php(332) : eval()'d code on line 29

Not sure if I am making a complete amateur mistake here in how I am sending the array over. Or is this simply not possible?

There is no methods like addFilter, addFunction and etc.

$function = new \Twig\TwigFunction('function_name', function () {
        // ...
    });

$view->addFunction($function);

Hi there. In Slim 2 i can set key in __construct like $this->view->set("foo","bar") via Slims/View. But in Slim 3 with Twig-view i can not set twig value in it. How can i set val outside of render function?

How would one bootstrap additional functions to extend Twig?

Hi

In the documentation of Twig, they write that it should be best practice to decouple the extension definitions from their runtime implementations. See https://twig.symfony.com/doc/2.x/advanced.html#definition-vs-runtime

Should we follow that recommendation?

I already tried to implement that. See https://github.com/adriansuter/Twig-View/tree/patch-runtimeExtension

It actually works, but of course, phpunit is giving me 21 errors 😨.

Users should be discouraged from using echo in their application, and we shouldn't use echo in the render method ourselves.

For me, the purpose of a PSR-7 based app should be the building of a valid response object during the application phase, and then sending that response at the end. I believe that if you are working with PSR-7 you shouldn't ever be writing to the output directly.

My proposal is to change the render method to the following:

 public function render(Response $response $template, $data = [])
{
    return  $response->write($this->fetch($template, $data));
}

We should be using proper accessors on the container in our example.

        $basePath = rtrim(str_ireplace('index.php', '', $container->get('request')->getUri()->getBasePath()), '/');
        $view->addExtension(new \Slim\Views\TwigExtension($container->get('router'), $basePath));

I keep getting this error when i try to use the twig template engine with Slim.
this is my composer.json

{
"require": {
"slim/slim": "^3.8",
"directus/sdk": "0.2.*",
"slim/twig-view": "dev-master"

},

"minimum-stability": "dev",
"repositories": [
    {
        "type": "git",
        "url": "https://github.com/wellingguzman/zend-db"
    }
]

}

below is a screen shot of the codes

The TwigMiddlewareTest should be refactored to remove duplicate code.

Currently this has only url_for function. The old Slim-Views has 4 different helpers. A simple solution would be to add Slim\App as a global. It would look like this:

{% if slim.request.isGet %}
    <a href="{{ slim.request.uri.basepath ~ slim.router.urlFor('home') }}">link</a>
{% endif %}

It's not as pretty as few selected helpers but the API is would same as in PHP code. Unfortunately it would also make it possible to include application logic into templates which may have unwanted side effects.

in slim 2
we have render function
as
` $app->render('email.twig')'

but in slim we have to add $response in twig render :( is there any way to render templates without using $response or hold twig render in a variable?

Sometimes I need to include small template within other twig template. In symfony there is render() function in twig for this. I wrote twig extension which adds this functionality with Slim 3. It is quite short and I think we can add it to twig-view. I believe that many users with slim+twig could benefit from this.

usage can be as simple as:

{{  render('Admin\\Action\\UserAction:info', { 'msq' : 'test'}) }}

where Admin\Action\UserAction is registered callable in container.

What is you opinion on this? Is this usecase scanario common enough to include this function to twig-view? I have it working and I can create pull request if so.

My file structure looks like this:

---public(Documentroot folder, where all my css,js, images loads from)
---models
---modules {all my modules customer, db_management e.t.c)
---scripts
|---ivr_builder
|------ui-bootstrap-tpls-0.2.js
--twig_templates {All my ta}
|---layout.twig

In my index.php file, I have this:

use \Psr\Http\Message\ServerRequestInterface as Request;
    use \Psr\Http\Message\ResponseInterface as Response;

    require '../vendor/autoload.php';
    spl_autoload_register(function ($classname) {
        require "../models/" . $classname . ".php";
    });

    $config['displayErrorDetails'] = false;
    $app = new \Slim\App(["settings" => $config]);
    $container = $app->getContainer();
    // Register component on container
    $container['view'] = function ($container) {
        $view = new \Slim\Views\Twig(
           '/var/www/html/ivr/twig_templates', ['cache' => false]);


        $env = $view->getEnvironment();
            $lexer = new Twig_Lexer($env, array(
            'tag_comment'   => array('{#', '#}'),
            'tag_block'     => array('{%', '%}'),
            'tag_variable'  => array('[[', ']]'),
            'interpolation' => array('#{', '}'),
        ));
        $env->setLexer($lexer);
       $loader = new \ Twig_Loader_Filesystem('ivr/scripts/ivr_builder/ui-bootstrap-tpls-0.13.4.js');
       $env->getLoader();



        return $view;
    };

Then in my browser, I get this error:

My layout.swig header looks like this:

Please any suggestion on how why its not loading please on the browser

After updating my composer.json I get this error.

Unable to register extension "Slim\Views\TwigExtension" as it is already registered.

Any plans to create a common interface for views?

I've written a library that will accept any view object that implements a render method such as the one found in Slim\View\Twig.php and Slim\Views\PhpRenderer.php.

For now I plan to create a small library with a ViewInterface and have two implementations for Twig and PhpRenderer

use Psr\Http\Message\ResponseInterface;

}   

final class TwigView extends \Slim\Views\Twig implements ViewInterface                                                   
{

}

When I tried implementing this, using the usage example, it didn't work.

The first thing it "crashed" on, was that there is no "addExtension" method for the class \Slim\Views\Twig.
After checking it out, it looks like there should be a getEnvironment call before that. So it will be:

$view->getEnvironment()->addExtension(new Slim\Views\TwigExtension(

Which brings us to the next issue, there is no Slim\Views\TwigExtension class.

Any ideas?

From the code:

public function fetch($template, $data = [])
{
$data = array_merge($this->defaultVariables, $data);

return $this->environment->loadTemplate($template)->render($data);

}

public function render(ResponseInterface $response, $template, $data = [])
{
$response->getBody()->write($this->fetch($template, $data));

 return $response;

}
in "fetch" I can use pre-added variables but not in render.

PHP Parse error: syntax error, unexpected '.' in /base/data/home/apps/b~previewtechs-cloud/slim-app-skeleton:20170224t205746.399418087592248769/vendor/twig/twig/lib/Twig/Extension/Core.php on line 1552

"twig/twig": "^1.18|^2.0", I guess it is causing some trouble. Recently I just ran my application on my local machine with PHP 7.1. It works well but when I just deployed that app to Google App Engine (PHP 5.5.9 environment) then it raised error.

PHP Parse error:  syntax error, unexpected '.' in /base/data/home/apps/vendor/twig/twig/lib/Twig/Extension/Core.php on line 1552

So I am pretty sure it's because of PHP versioning. So if anybody want to avoid the issue, they need to manually add main "twig/twig" package in their installation. Otherwise, somebody can face compatibility issue after app deployment.

I think, we can add a small note in Readme.md file.

In Slim 2, I can easily add data before rendering with $this->view->appendData([]); However, In Slim 3, the only possible for me to do so is with $this->view->offsetSet($key, $value);

I think it would be great to pass an array instead of key value pair

The is_current_path method introduced in #64 is really useful. 👍

However, the method fails if the class is invoked with a string URI (see line #60) as demonstrated in the docs:

// Instantiate and add Slim specific extension
$basePath = rtrim(str_ireplace('index.php', '', $c['request']->getUri()->getBasePath()), '/');
$view->addExtension(new Slim\Views\TwigExtension($c['router'], $basePath));

It works fine when invoked using $c['request']->getUri():

$view->addExtension(new \Slim\Views\TwigExtension($c['router'], $c['request']->getUri()));

Curious — what's the advantage of using the docs approach over $c['request']->getUri()?

I'm using the twig view helper and it does not show anything... There is no error, nothing, just a blank white page. The server says "200"... I don't know what I'm doing wrong.

For example if I use the php-view package or simply do $response->getBody()->write("foo") it works. But with the twig-view it doesn't work.

app/
    cache/
    templates/
        home.twig
    src/
        App.php
        Twig.php
        Home.php
        ...
public/index.php
vendor/
...

I have my own App class, which holds an object of Slim\App. Here I create an object of my own Twig class, which executes this code:

$container = $app->getContainer();
$container["view"] = function ($container) {
    $view = new Slim\Views\Twig("../app/templates", [
        "cache" => "../app/cache"
    ]);

    $view->addExtension(new Slim\Views\TwigExtension(
        $container["router"],
        $container["request"]->getUri()
    ));

    return $view;
};

And instantiate an object of the Home class, with this code:

$app->get("/", function ($request, $response, $args) {
    return $this->view->render($response, "home.twig", []);
});

My template home.twig contains just <h1>Hello world!</h1>.

Can someone help me? Or do you need more information?

Already known here: #70, but just a quick note -- might be worth highlighting this requirement specifically in the readme (maybe under install, too), since it could be overlooked.

Running various versions of PHP locally as needed, so composer update changed to Twig 2.x. Production server was running PHP 5.6 (so it broke briefly).

Hi.

The docs are a little lacking when it comes to using twig 2.x

Can they be updated to reflect how to force usage of twig 2.x?

First the $this->view only works for Pimple with their __get() implementation.
Second most container use the same instance as default or can be configured to.
Third messing with container is considered a code smell.
Fourth it's better to save the view in Request attribute rather than mess around with container.

Curious if I'm missing something with the undocumented "defaultVariables" feature, or if it's just an accident of history...

Is there any use-case where "defaultVariables" offers any benefit over using twig's built-in Globals method?

For example:

$this->view->getEnvironmnent()->addGlobal('myVar', 123);

...versus:

$this->view['myVar'] = 123

Seems that a proxy method could be added to Twig-View (like the addExtension method) and this would serve the same purpose without having to clutter up the Slim\Views\Twig class with that ArrayAccess implementation. Or perhaps there's something that can be done (or is used elsewhere in the system) with the "defaultVariables" thing that can't be done with twig's built-in globals functionality?

Thanks!

Hi,

With slim previous version (2.x), it was quite easy to access flash messages from twig... This feature was quite useful. Any idea on when something similar will be available ?

Regards,

Sylvain

For some reason Twig->render() doesn't return a response. What does work for me is this:

    public function render(ResponseInterface $response, $template, $data = [])
    {
       $response->getBody()->write($this->fetch($template, $data));

        return $response;
    }

I have the same setup like the usage section in the readme and every time i use the block function from twig the content is wrapped into a

 tag..

example:

layout.twig

{% block content %}{% endblock %}
test.twig
{% extends 'includes/layout.twig' %}

{% block content %}
test
{% endblock %}

output

<pre>test</pre>
how i can disable the  <pre> tag ?
UPDATE: forgot the block part, anything inside the body is wrapped with a <pre> tag.

UPDATE 2: Its a issue from some chrome addon.
    

Please show us how to use session.

I've read some of the closed issues and it seems that no one, is actually having an issue using path_for. I have double and triple check for typos.

{{ path_for('home', {'name': 'home'}) }}

Everything else is working great. Any ideas what is going on?

i am using twig in my project, i have a problem about the twig.

public function postSignUp(Request $request, Response $response)
{
var_dump($request->getParams());
}

I think the result should be

string(15) "[email protected]"
["name"]=>
string(4) "test"
["password"]=>
string(12) "testpassword"
}

but actually the browser show me

string(15) "[email protected]" ["name"]=> string(4) "test" ["password"]=> string(12) "testpassword" }

Hello, I can use composer to get Twig-View, but not to get Slim in version 3. But Twig-View would only work with version 3. Is it possible to add Slim in version3 to the packagist for composer?
By the way, thanks for this amazing framework.

For me, the usage example doesn't work.

return $this["view"]->render($response, 'profile.html', [
    'name' => $args["name"]
]);

With this I got the error: "Cannot use object of type Slim\App as array".

return $this->view->render($response, 'profile.html', [
    'name' => $args["name"]
]);

This works fine for me.

What is the problem now? :D

I read the code and did not find a register() method for the Slim app object, do I need an specific version of the Slim fw to use this? I'm using 2.6.2, the one that composer downloaded.

Not sure if this is covered in the missing helpers, should this support flash messages?

This interface does not exist in Twig.

Where is it defined? The Twig project only has Environment and that one has no interface.

The path_for returned string starts with a slash, this is inconvenient for applications inside a subdirectory.

Example:

Route definition

$app->get('/{slug}', 'App\Action\ItemAction:dispatch');

Template

<a href="{{ path_for('item', {'slug': item.slug}) }}">
  {{ item.name }}
</a>

produces /itemslug, which is evaluated inside a browser to http://localhost:8000/itemslug on my dev server. As my application is within project/alpha subdirectory, I'd prefer some helper function which creates as string which evaluates to http://localhost:8000/project/alpha/itemslug.

In the head of the document I'm using base element <base href="{{ base_url() }}/" /> so all links may be relative.

I can use both: base_url() ~ path_for() but IMHO it's an overhead to list scheme, domain, port etc in each hyperlink - a relative or absolute path would be sufficient.

So I wonder how the application URLs should be created in the Twig-View?

Reintroduce the url_for function which would create URLs not paths, or trim starting slash in path_for? If so, should it happen it in the Twig-View or in the Slim::Router package?

Hi guys
Twig's new version is 2.x, But Twig-View only supports 1.x.

Hi,

I have controller and for example on Login post action, if there are errors or on success login, I'd want to user be redirected login page with errors or dashboard page. How can I do that?

If I write $this->view->render(...); it opens up in the same url (/login/post)...

Thanks

I am getting error
Unknown "path_for" function in "/Templates/Partials/index.twig" at line 11.
here is index .twig

{% extends "Base.twig" %}

<header class="main_menu_sec navbar navbar-default navbar-fixed-top">

here is view in container
`$container['View'] = function ($container)
{
return new \Slim\Views\Twig( DIR . '/../App/Views',[
'cache' => false //dirname(FILE) . '/../Caching'
]);

$View->addExtension(new Slim\Views\TwigExtension(
     $container['router'],
     $container['request']->getUri()

 ));

return $View;

};`

How to use multiple paths per namespace?

I cant find the docs for base_url.

I know it's there but a few people stop by the support channels looking for it.

I modified it to work with my installation :

public function isCurrentPath($name)
{
    if ($this->uri->getBasePath()) {
        if ($this->uri->getPath() == '/') {
            return $this->router->pathFor($name) === $this->uri->getBasePath() . '/';
        } else {
            return $this->router->pathFor($name) === $this->uri->getBasePath() . '/' . $this->uri->getPath();
        }
    } else {
        return $this->router->pathFor($name) === $this->uri->getPath();
    }
}
