I am trying to use Twig with CakePHP, so I installed this plugin:
https://github.com/predominant/TwigView
And in CakePHP's demo, we build a blog, and I can use this in a tpl file:
{% for post in posts %}
<tr>
<td>{{post.Post.id}}</td>
<td>{{post.Post.title}}</td>
<td>Edit | Delete</td>
<td>{{post.Post.created|date("F j, Y")}}</td>
</tr>
{% endfor %}
What I can't get to work, is converting this:
<?php
echo $this->Html->link(
'Add Post', array('controller' => 'posts', 'action' => 'add')
);
?>
I have tried all of these, and none of them work:
{{ html.link("Add Post", {"controller" : "posts", "action" : "add"}) }}
{{ _view.html.link("Add Post", {"controller" : "posts", "action" : "add"}) }}
{{ this.html.link("Add Post", {"controller" : "posts", "action" : "add"}) }}
I don't get any errors, it just gets replaced with nothing. Anyone know how I can fix this issue?
You have to explicitly declare the helpers in the controller to make it work:
public $helpers = array('Html', 'Form');
See GitHub issue #14 and #13 where I got this from.
Maybe it just won't take an array as the argument or doesn't understand what controller or action is. Try:
{{ html.link("Add Post", "/posts/add" }}
Is it escaping the output? If so, to get the full HTML, use RAW
{{ html.link("Add Post", {"controller" : "posts", "action" : "add"})|raw }}
Proper syntax for hyperlinks html helper is:
{{ html.link('Add Post', '/posts/add') }}

I am trying to use the url Twig function with Silex to generate a route, but when I use the variable name that I have passed to the template it generates a warning that I have not supplied the parameter.
This is the array I am passing to the template:
[
"total_pages" => $pages,
"current_page" => $page,
"route_name" => "gallery_album",
"route_parameter" => "groupname",
"route_value" => $groupname
]
And in the template I am trying to use:
{{ url(route_name, {route_parameter: route_value, 'page': page} ) }}
(The page variable value is worked out in the template)
This is part of a pagination template that I am building so I need the parameter to be a variable so it can be applied to different pages. This is the error I get when I run this:
I feel this is something that is very simple, I am just missing something fundamental.
It thinks that route_parameter is a string key name and not a variable:
You can do for example:
{% set params = {'page': page, (route_parameter): route_value } %}
{{ url(route_name, params) }}
You can use {{ app->path}} or {{ app->url }}
if you using Silex\Application\UrlGeneratorTrait in you Application class
or alternative using this
{{ app.url_generator.generate('homepage') }}
Trying to render a dropdown in Symfony 2.7.0 but I am having some issues when rendering the choices the view.
$form = $this->createFormBuilder(null)
->add('timespan', 'choice', array(
'choices' => array(90 => "3 months", 30 => "1 month")
))
->getForm();
...
return array(
'form' => $form->createView(),
);
...
Doing var_dump after this will display the values:
var_dump($form->get('timespan')->getConfig()->getOption('choices'));
But when rendering it in the view like this:
{{ form_widget(form.timespan, {'class': 'span2'}) }}
The select box becomes empty.
<select id="form_timespan" name="form[timespan]" required="required" class="span2"></select>
Any ideas why this might occur? Am I missing something?
The problem is obviously in Twig. You can debug this by editing the form theme, to see what values comes in and what is expected. The theme can be found at:
vendor/symfony/symfony/src/Symfony/Bridge/Twig/Resources/views/Form/bootstrap_3_layout.html.twig
(Or you can configure Symfony to use your own.)
You're looking for {% block choice_widget %} specifically to render this.
In this case it looks like you've forgotten to use the attr key for your HTML class:
{{ form_widget(form.timespan, {'attr': {'class': 'span2'}}) }}
You forgot the attr key in your call :
{{ form_widget(form.timespan, {'attr': {'class': 'span2'}}) }}
Below is my code for a Laravel 4 project.
Going to the authors/create URL and submitting the form gives me a 405 error.
However, if I prepend the routes.php file with Route::post('authors/store', 'AuthorsController#store');, basically doubling what it already should do, everything works like a charm!
Why do I need do prepend said line in my code to work? I can only assume I'm doing something wrong here.
routes.php:
Route::resource('authors', 'AuthorsController');
AuthorsController.php:
public function create() {
$view = View::make('authors.create');
return $view;
}
public function store() {
//
}
authors/create.twig:
{{ form_open({'url':'authors/store'},{"method" : "post"}) }}
<p>
{{ form_label("Name", "name") }}
{{ form_text("name") }}
</p>
<p>
{{ form_submit("Add Author") }}
</p>
{{ form_close() }}
The store action get's trigger when you POST to the resource. So just authors and not authors/store:
{{ form_open({'url':'authors'},{"method" : "post"}) }}
See this table on more information what URL corresponds to what controller action.
Also I think it should be like this:
{{ form_open({'url':'authors', 'method' : 'post'}) }}
And you can pass the route name Laravel automatically generates to make your life a bit easier:
{{ form_open({'route':'authors.store', 'method' : 'post'}) }}
Oh and one more, post is the default method so this should do as well:
{{ form_open({'route':'authors.store'}) }}
I am converting the PHP based template to TWIG based template in FuelPHP.
echo Html::anchor('categories/create', 'Add', array('class' => 'btn'));
I found out with some help that the equivalent tag for TWIG is html_anchor which works fine. But as in this case, there is an third parameter passed as an array. How that can be converted for TWIG?
I tried the below found 2 lines and both failed with error so I assume its not the correct way.
{{ html_anchor('categories/create', 'Add', array('class' => 'btn')) }}
Twig arrays has [] format, so I tried this too.
{{ html_anchor('categories/create', 'Add', ['class' : 'btn']) }}
What's the correct way of handling this?
Here's how you define an associative array in twig:
{{ html_anchor('categories/create', 'Add', { 'class': 'btn' }) }}
I have a simple blog with Post resource and Comment nested resource.
Until now I can see all the comments belonging to a post and create a new comment for a post.
I want to give the possibility to delete a specific comment, but somehow I am making some mistakes.
This is the view comments.index with all the comments:
#extends('master')
#section('blog')
#foreach($comments as $comment)
<div class="span11 well">
<ul>
<li><strong>Body: </strong> {{ $comment->body }} </li>
<li><strong>Author: </strong> {{ $comment->author }}</li>
</ul>
{{ Form::open(array('method' => 'DELETE', 'route' => array('posts.comments.destroy', $post_id), $comment->id)) }}
{{ Form::submit('Delete', array('class' => 'btn btn-danger')) }}
{{ Form::close() }}
</div>
#endforeach
{{ link_to_route('posts.index', 'Back to Post index') }}
This is the error i get running the index: Parameter "comments" for route "posts.comments.destroy" must match "[^/]++" ("" given) to generate a corresponding URL.
This is the Index method inside CommentsController:
public function index($post_id)
{
$comments = Post::find($post_id)->comments;
return View::make('comments.index', compact('comments'))->with('post_id', $post_id);
}
And this is the Destroy method inside CommentsController:
public function destroy($post_id, $comment_id)
{
$comment = $this->comment->find($comment_id)->delete();
return Redirect::route('posts.comments.index', $post_id);
}
Someone can tell me please where I am making the mistake?
This the routes:
Route::resource('posts', 'PostsController');
Route::resource('posts.comments', 'CommentsController');
You have put a regexp tester on your route, to check your comments parameter.
This error message says that parameter that you give to Laravel isn't good.
If your parameter is only a decimal id, use \d+ regexp instead.
Without your routes.php file - I cant be sure, but I think this might be the problem.
Change
{{ Form::open(array('method' => 'DELETE', 'route' => array('post.comments.destroy', $post_id), $comment->id)) }
to
{{ Form::open(array('method' => 'DELETE', 'route' => array('post.comments.destroy', array ($post_id, $comment->id))) }
If this does not work - please post your routes.php file.
Edit: You have defined your route as a "resource". This means your destroy route is defined with only one variable. You dont actually need the $post included, so just define this:
{{ Form::open(array('method' => 'DELETE', 'route' => array('posts.comments.destroy', $comment->id))) }}
and change your destroy method to this - there is no need for the $post to delete a $comment:
public function destroy($comment_id)
{
$comment = $this->comment->find($comment_id)->delete();
return Redirect::back();
}
