I am trying to implement a webcam barcode reader to search in my grid but I don't understand how to implement it.
This is in the jakobreiter documentation but not sure the html markup i need to use to make it work.
echo YiiQuagga::widget([
"id" => 'codereader',
'name' => 'BarcodeForm[number]',
'target' => '#barcodeform-number',
'messages' => '#messages',
]);

I'm looking for 2 specific variables.
Wishlist - The var_message variable has some styling to it that im trying to edit.
Abandoned Carts - pulls on this extension URL : connector/email/basket/code/secret/quote_id/*****
And im unable to find the location of the file that is accessed by that URL or command.
Any assistance that can be provided would be greatly appreciated.
Also if someone could tell me how i might trace the locations of these things without "Just knowing" that would be grand too.
Kind Regards,
the correct variable name is message (not var_message)
variable message is populated in controller Mage_Wishlist_IndexController
inside method sendAction
here it is:
$emailModel = Mage::getModel('core/email_template');
$sharingCode = $wishlist->getSharingCode();
foreach ($emails as $email) {
$emailModel->sendTransactional(
Mage::getStoreConfig('wishlist/email/email_template'),
Mage::getStoreConfig('wishlist/email/email_identity'),
$email,
null,
array(
'customer' => $customer,
'salable' => $wishlist->isSalable() ? 'yes' : '',
'items' => $wishlistBlock,
'addAllLink' => Mage::getUrl('*/shared/allcart', array('code' => $sharingCode)),
'viewOnSiteLink' => Mage::getUrl('*/shared/index', array('code' => $sharingCode)),
'message' => $message
)
);
}
$wishlist->setShared(1);
$wishlist->save();
and the actual content of the message comes from a form input and gets fetched over here:
$message = nl2br(htmlspecialchars((string) $this->getRequest()->getPost('message')));
there is no actual styling or css assigned to it. In fact most of styles are defined inline in email templates
I can upload files with special field upload_multiply and then save their names in DB, but how to print them back when editing the record? I use one-to-many relation, database structure like objects and objects_images, where exist object_id, name and url of uploaded image. Im using Laravel 5.4.
Now my code is very typicall:
I have a ObjectCrudController where i build form for my project. I use buildt-in Backpack/CRUD fields like this (for categories):
$this->crud->addField([
'label' => 'Category to display',
'type' => 'select',
'name' => 'category_id',
'entity' => 'category',
'attribute' => 'name',
'model' => 'App\Models\Category',
'wrapperAttributes' => [
'class' => 'form-group col-md-4'
]
]);
But I cant understand how to upload some images and then display their records as miniatures, also i need an ability to remove already uploaded image record. I think there can be used something like html field or view from backpack CRUD, but i don't know where to start.
I have a JSON file with all world languages and would like to put them into choices array inside ChoiceType form field.
$builder->add('languages', ChoiceType::class, array(
'choices' => array()
))
My JSON file is stored: projectname/web/bundles/index/json/languages.json
Is it possible to achieve it without writing JS / AJAX?
P.S. EventListeners or other alternatives that Symfony2 provides suits me well.
You could reach the file with DIR, since I dont' know where the php file with builder is located, it could looks like:
$builder->add('languages', ChoiceType::class, array(
'choices' => json_decode(
//if builder is in controller, this should work
file_get_contents(__DIR__.'/../../../web/bundles/index/json/languages.json'),
true)
));
I have been following this guide to load my menu configuration and i think it is very nice and clean way to load the menu.
My question is simple, is there a way to load your ACL configuration on the same way with a config array and some kinda of factory?
If there isn't, how do i load a ACL configuration and use with that menu in a easy way?
Thanks!
Edit:
This is a very good blog post on why use modules that is already done and not make your own, http://hounddog.github.com/blog/there-is-a-module-for-that/
ZF2 contains ACL and also RBAC (role based ACL - might be in ZF2.1), but to put it in place, easier is to use module which you can plug into your application. BjyAuthorize seems to me a bit bloated, you have to use ZfcUser module. I prefer ZfcRbac, the ACL rules are based on user roles (group) and their access to controller, action or route. Configuration stored in one config file, really easy to implement.
Most likely there are several ways to do it, but I prefer to do it in getViewHelperConfig() of application's Module.php (here I use BjyAuthorize module to simplify work with ACL, and in particular it allows to set ACL rules in configuration file module.bjyauthorize.global.php)
public function getViewHelperConfig()
{
return array(
'factories' => array(
'navigation' => function($sm) {
$auth = $sm->getServiceLocator()->get('BjyAuthorize\Service\Authorize');
$role = $auth->getIdentityProvider()->getIdentityRoles();
if (is_array($role))
$role = $role[0];
$navigation = $sm->get('Zend\View\Helper\Navigation');
$navigation->setAcl($auth->getAcl())->setRole($role);
return $navigation;
}
)
);
}
Play with This structure . get role and resource from database and save this in session for or any caching .
You are right, there is no out-of-the-box-all-in-one solution. You have to build some bridges between the modules.
Another easy way to integrate BjyAuthorize is using **Zend Navigation**s default methods as described by Rob Allen:
Integrating BjyAuthorize with ZendNavigation
$sm = $e->getApplication()->getServiceManager();
// Add ACL information to the Navigation view helper
$authorize = $sm->get('BjyAuthorizeServiceAuthorize');
$acl = $authorize->getAcl();
$role = $authorize->getIdentity();
ZendViewHelperNavigation::setDefaultAcl($acl);
ZendViewHelperNavigation::setDefaultRole($role);
You can also use ZfcRbac and use a listener to make it work with Zend Navigation.
Since this is a lot of code I simply post the link here:

I've just created an ACL module that creates an ACL Service parsing the routes.
To manage your access control to your application you only need to define roles and add a new key 'roles' in every route. If you do not define that key or its array is empty, then the route becomes public. It also works with child routes.
As an example:
array(
'router' => array(
'routes' => array(
'user\users\view' => array(
'type' => 'Segment',
'options' => array(
'route' => '/admin/users/view/id/:id/',
'constraints' => array(
'id' => '[0-9]+',
),
'defaults' => array(
'controller' => 'User\Controller\Users',
'action' => 'view',
'roles' => ['admin', 'user'],
),
),
),
),
),
);
The module can be installed via composer and it is now listed in the zend modules repository: http://zfmodules.com/itrascastro/TrascastroACL
You can get more detailed info about use and installation from my blog: http://www.ismaeltrascastro.com/acl-module-zend-framework/
Normally a widget is used by calling CController::widget() on an instance of CController, typically $this in a view.
But if I'm writing a static method, a helper, say, then I don't have access to an instance of CController. So how do I use a widget?
Let's say further that this helper method is invoked in the eval()’ed expression in a CDataColumn's value property. That poor expression has almost no context at all. How should the helper use a widget?
EDIT: Code example
As requested, a view example:
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider' => $model->search(),
'columns' => array(
array(
'name' => 'attrName',
'value' => '--USE WIDGET HERE--',
),
)
));
This answer doesn't answer the question in general but in the specific case—how to access the controller and use a widget in the context of the evaluated expression of CDataColumn::$value—you can use this:
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider' => $model->search(),
'columns' => array(
array(
'name' => 'attrName',
'value' => function ($data, $row, $column) {
$controller = $column->grid->owner;
$controller->widget(/* ... etc ... */);
},
),
)
));
The trick was discovering that CDataColumn::renderDataCellContent() uses CComponent::evaluateExpression(), which injects the component instance into the callback as the last parameter. In this case that omponent is the CDataColumn, which references the controller as shown.
I don't like writing PHP expressions as string literals so I'm pleased to find this option.
A comment on http://www.yiiframework.com/doc/api/1.1/CDataColumn#value-detail shows another way to us a widget in a column value that I haven't tried.
This one is working solution for calling widgets in static methods in Yii
Yii::app()->controller->widget('widget');
There's no direct way to call a widget out of controller because you shouldn't do so. It's all about MVC. Widgets are only needed and/or useful in views, and views are only accessed via controllers. That's the theory.
I guess you're approaching the problem mistakenly. A proper, MVC-friendly way to do what your're trying to do involves using renderPartial(). You know: you a have certain content and you want to decorate it (in your case you want to imbibe it inside a widget, right?) before displaying it to final user; so, from the view, you call renderPartial(). It will send your data to a file where it will properly decorated. renderPartial() returns the content properly formatted and now you can display it in the view.
Unfortunately, in your particular case, you're working with grid view (right?) and, at least from my point of view, it makes the things a bit harder. In order to decorate content for a CGridColumn-subclass element (like CDataColumn), you need to override the renderDataCellContent() method.
