I need to get current_page in needs_context of my function.
It's working correctly, but needs_context stays empty.
My class Helper extends \Twig_Extension
class Helpers extends \Twig_Extension {
public function getName() {
return 'Helpers';
}
public function getFunctions() {
return [
new \Twig_SimpleFunction('activeClass', [
$this,
'activeClass'
], [
'needs_context' => true
])
];
}
public function activeClass($context, $page) {
if (isset($context['current_page']) && $context['current_page'] === $page){
return ' active ';
}
}
In my .twig file
Foo
I hope with this function to return active class for the current href in the navbar. I use Slim v3 with his extension Twig-view.
Thanks for your help.
I resolved the problem.
Because I use a extension of Twig for Slim and no Twig, it's different.
Normaly, we use needs_context to extract the value of the current_page.
But with Twig-view for Slim PHP, we can use {% if is_current_path('your_page') %}class="active"{% endif %}
Sincere thanks to #martias and #DarkBee for their help.

I'm having a problem with my controller, when I try to call request->isAJAX() the program returns the error undefined method
Note : i'm using codeigniter 4.1.1
<?php
namespace App\Controllers;
use App\Models\Mruang;
class Ruang extends BaseController
{
protected $jenis;
public function __construct()
{
$this->jenis = new Mruang();
}
public function index()
{
$data = [
'titel' => 'Jenis Ruang'
];
return view('ruang/index', $data);
}
public function tampil()
{
if ($this->request->isAJAX()) {
$data = [
'ruang' => $this->jenis->findAll(),
'btn' => true
];
$msg = [
'data' => view('ruang/data', $data)
];
echo json_encode($msg);
}
}
}
I run your code at my local machine in a CI 4.1.1 installation and it runs ok, at least the $this->request->isAJAX() worked as expected.
Look at your BaseController and compare it with the default. I pasting the default code bellow
<?php
namespace App\Controllers;
use CodeIgniter\Controller;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use Psr\Log\LoggerInterface;
class BaseController extends Controller
{
protected $helpers = [];
public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger)
{
// Do Not Edit This Line
parent::initController($request, $response, $logger);
}
}
I also would like to recommend you to look if Mruang model has the findAll() methods.
In a twig form template in Symfony 4 app I need to have an attribute with a variable.
Exemple:
{{ form_widget(myform.field, {'attr': {'class': 'bidding-slider','data-slider-value': '800'}}) }}
I need to put a variable in 'data-slider-value' instead of a manual value.
I tried :
{{ form_widget(myform.field, {'attr': {'class': 'bidding-slider','data-slider-value': '{{ variable }}'}}) }}
but it do not work...
{{ variable }} alone return well the value I need to put in 'data-slider-value'.
Second tried:
I have Extended form class 'TextType' method buildView.
To do that I added this file : src/Form/Extension/TextTypeExtension.php
// src/Form/Extension/TextTypeExtension.php
namespace App\Form\Extension;
use Symfony\Component\Form\AbstractTypeExtension;
use Symfony\Component\Form\Extension\Core\Type\FileType;
class TextTypeExtension extends AbstractTypeExtension
{
/**
* Return the class of the type being extended.
*/
public static function getExtendedTypes(): iterable
{
// return FormType::class to modify (nearly) every field in the system
return [TextType::class];
}
public function buildView(FormView $view, FormInterface $form, array $options)
{
$tjm = $form->get('dailyrate')->getData();
$view->vars['attr']['data-slider-value'] = $tjm;
}
}
But now I am not sure of the way to use that in my form template...
Thank you very much for helping me.

Extend your form's class method buildView:
public function buildView(FormView $view, FormInterface $form, array $options)
{
$view->vars['attr']['data-slider-value'] = ...//
}
Need to get the URL in a template.
I have tried using get.request.url and it always returns blank. I've tried get.request.attributes.get('_route') and it always returns blank. Since I'm new to twig I'm sure I'm missing something fairly basic and easy.
As you are working with twig standalone, u'd need to pass the information yourself. You could create a small wrapper class to solve this for you though.
Request.php
class Request {
public function __construct() {}
public function get($key) {
return isset($_GET[$key]) ? $_GET[$key] : null;
}
public function post($key) {
return isset($_POST[$key]) ? $_POST[$key] : null;
}
public function url() {
$http = 'http'.(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? 's': '');
return $http.'://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
}
}
And register the class as a global into twig:
<?php
require_once __DIR__.'/vendor/autoload.php';
$loader = new Twig_Loader_Filesystem(__DIR__.'/../views');
$twig = new Twig_Environment($loader);
$twig->addGlobal('request', new Request());
Now you can use your wrapper inside twig
{{ request.url }}{# output current url #}
{{ request.get('variable') }}{# contents of $_GET['variable'] when set or null #}
{{ request.post('variable') }}{# contents of $_POST['variable'] when set or null #}
I'm having problem with displaying form when using CollectionType. It doesn't show newOrderCustomerType inputs, just label "Customer Id". Whats wrong?
newOrderCustomerType
<?php
namespace AppBundle\Form;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class newOrderCustomerType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->
add('firstname', TextType::class,array('label'=>'Firstname'))->
add('lastname', TextType::class,array('label'=>'Lastname'))->
add('email', TextType::class,array('label'=>'Email'))->
add('login', TextType::class,array('label'=>'Login'));
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\Customer',
));
}
public function getName()
{
return 'app_bundlenew_order_customer_type';
}
}
newOrderType
<?php
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class newOrderType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('customerId',CollectionType::class,array(
'entry_type'=>newOrderCustomerType::class,
'allow_add' => true,
'by_reference' => false,
'data_class' => 'AppBundle\Entity\Customer',
))
->add('shopOrderId')
->add('orderDate')
->add('postBuyFormMsg')
->add('invoice')
->add('payType')
->add('shipmentType')
->add('payStatus')
->add('save',SubmitType::class);
}
public function configureOptions(OptionsResolver $resolver)
{
}
public function getName()
{
return 'app_bundlenew_order_type';
}
}
And in TWIG template
{{ form_start(orderForm) }}
{{ form_widget(orderForm) }}
{{ form_end(orderForm) }}
How to make it show all input fields?
If you have an active "allow_add" option, it is possible to render this input throught the 'prototype' option:
$builder
->add('customerId',CollectionType::class,array(
'entry_type'=>newOrderCustomerType::class,
'allow_add' => true,
'by_reference' => false,
'data_class' => 'AppBundle\Entity\Customer',
'prototype' => true,
))
and then in the form:
{{ form_row(orderForm.customerId.vars.prototype}) }}
It should work.
For more, see the Symfony documentation of prototype option
Try removing 'data_class', I don't think that's part of CollectionType:
->add('customerId',CollectionType::class,array(
'entry_type'=>newOrderCustomerType::class,
'allow_add' => true,
'by_reference' => false,
))
See if that works.
I would like to extend core Twig in Bolt cms with
http://twig.sensiolabs.org/doc/extensions/text.html
What is best way to do it?
Yes, it can be done by creating a simple Bolt extension:
<?php
namespace Bolt\Extension\Gawain\MyTwigExtension;
class Extension extends \Bolt\BaseExtension
{
public function getName()
{
return "MyExtension";
}
public function initialize()
{
$this->addTwigFunction('foo', 'twigFoo');
}
public function twigFoo()
{
$html = "<p>bar</p>";
return new \Twig_Markup($html, 'UTF-8');
}
}
