I want to show a modal when triggered by my custom class library, but without explicity calling any of its methods from outside.
I would have to wait until view template is loaded.
How can I make my library's methods wait until view is loaded?
As first step I have already added my library to the autoload array.
Did you try Hooks?
Following may work but not sure. Didn't try myself.
$hook['post_controller'] = array(
'class' => 'MyClass',
'function' => 'Myfunction',
'filename' => 'Myclass.php',
'filepath' => 'hooks',
'params' => array('beer', 'wine', 'snacks')
);

Right now I'm trying to implement themming for my Yii2 based project.
How I see the thing now:
User chooses an application theme from the list on the settings
page in backend.
Using yii2-settings I'm saving all the
configuration data in DB (pretty easy).
In the application
bootstrap.php I'm creating new alias called #theme. Basically it
should lead us to a application theme base path (used in search
paths, assets manager, e.t.c.).
According to official
documentation, that's how I configured my view component:
'view' => [
'theme' => [
'basePath' => '#theme',
'baseUrl' => '#theme',
'pathMap' => [
'#app/views' => '#theme',
'#app/widgets' => '#theme/widgets',
'#app/modules' => '#theme/modules',
],
],
],
An issue I have is with p.3. According to yii2-settings documentation that's how I supposed to read the settings:
$theme = Yii::$app->settings->get('name', 'general');
Yii::setAlias('#theme', realpath(dirname(__FILE__)."/../../themes/$theme"));
But obviously, it's not working for me because of yii2-settings component didn't initialized yet when bootstrap.php is called. I've been trying to initialize it later in the init() method of my base controller, then adjust other aliases manually, but I feel that way being somewhat 'unclean', and also it still fails because of #theme alias is also used in asset file which is Yii2 starting to publish before calling the controller's init method.
So does anyone has any thoughts of how to do that 'hacking' the code as less as possible? I know I could just move configuration to some file, then read it manually before the application initialization, but it's still not the way I want to go.
Maybe there's some way to override some system component to set the alias after db component is loaded, but before view component configuration? Or Yii loads this components in a different order? Anyway. Any help would be appreciated!
You could try an Application Event in bootstrap:
\Yii::$app->on(\yii\base\Application::EVENT_BEFORE_REQUEST, function ($event) {
$theme = Yii::$app->settings->get('name', 'general');
Yii::setAlias('#theme', realpath(dirname(__FILE__)."/../../themes/$theme"));
});
OR in configuration file:
[
'on beforeRequest' => function ($event) {
// ...
},
]
From Yii 2 docs:
EVENT_BEFORE_REQUEST This event is triggered before an application
handles a request. The actual event name is beforeRequest.
When this event is triggered, the application instance has been
configured and initialized. So it is a good place to insert your
custom code via the event mechanism to intercept the request handling
process. For example, in the event handler, you may dynamically set
the yii\base\Application::$language property based on some parameters.
Here's the final solution:
config/bootstrap.php:
// Setting a temporary path for components configuration - will be changed later
Yii::setAlias('#theme', realpath(dirname(__FILE__)."/../../themes/"));
config/main.php
'components' => [
'view' => [
'theme' => [
'basePath' => '#theme',
'baseUrl' => '#theme',
'pathMap' => [
'#app/views' => '#theme',
'#app/widgets' => '#theme/widgets',
'#app/modules' => '#theme/modules',
],
],
],
],
'on beforeRequest' => function ($event) {
$theme = Yii::$app->settings->get('theme', 'general');
Yii::setAlias('#theme', realpath(dirname(__FILE__)."/../../themes/$theme"));
},
I'm using codeigniter and have a controller Checkme.php and function inside talkcheck. Via url i can access it like http://site.com/checkme/talkcheck
I want this to run every time when codeigniter is loaded ( page requested ), how would I go with this?
I tried solution from here but it overwrittes exiting object and half of my methods don't work
You can use a hook to run a function on every page load by setting enable_hooks to TRUE in config.php and adding the following code to config/hooks.php
$hook['pre_controller'] = array(
'class' => 'Checkme',
'function' => 'talkcheck',
'filename' => 'Checkme.php',
'filepath' => 'controllers'
);
I'm trying to make a website using the Zend Framework 2, but I have a simple problem driving me crazy.
I'd like to make a simple about-us.html page with static content because there is no need to do anything else than display html.
There is no need to create a Controller / model etc...
Maybe you have to question why you're using ZF in the first place. If you just want to create a static internet page, do that without a PHP framework!
If you didn't ask your question well and you're actually just adding a static page to an existing ZF application, why not just using the existing IndexController, add an empty action and add your static content to the corresponding .phtml?
Alternatively you can look at PhlySimplePage, a ZF2 module for the purpose of adding simple static pages to a ZF app. It's written by Matthew Weier O'Phinney, the lead dev of ZF.
As the readme says, this module eliminates the need to create a controller and an action. So all you need to do is create a route and a view script.
I know this question might be old, but I was in trouble with that as well.
Here is what I did to create a generic router for my application, so I could just add as many actions as I need and have then created as phtml files in my view
on module.config.php
'application' => array(
'type' => 'Segment',
'options' => array(
'route' => '/[:action][/]',
'constraints' => array(
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
),
'defaults' => array(
'controller' => 'Application\Controller\Index',
'action' => 'index',
),
),
),
So basically what it does is gets any action you might have in your application and use as a page... like any other controller
Instead of http://yoursite.com/application/test
you can do now http://yoursite.com/test
if you have your testAction set in your indexController file.
Hope I had helped future people looking for this information.
You have to create controller and view file.
suppose there is a about us menu with link
<a href="<?php $this->url('aboutus'array('action'=>'aboutus'));?>">
About Us
</a>
Just go to aboutus view file and write static html code.
Thanks

I've created a module, a basic copy of the the albums example given in the ZF2 documentation, however, with the new module, I am not able to access it at all - I'm always given a 404 error. I'm building this on the ZF2 skeleton.
I've got three modules loaded: Application, Frontend and Security.
Both Frontend and Security are duplicates of each other, however, I have thoroughly checked and there is no reference to old code (as I literally copied the module folder and renamed/rewrote references).
The module is also loaded in application.config.php.
Any ideas on what I'm missing?
Module Config:
return array(
'controllers' => array(
'invokables' => array(
'Security\Controller\Security' => 'Security\Controller\SecurityController',
),
),
'router' => array(
'routes' => array(
'security' => array(
'type' => 'segment',
'options' => array(
'route' => '/security[/:action][/:id]',
'constraints' => array(
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
),
'defaults' => array(
'controller' => 'Security\Controller\Security',
'action' => 'index',
),
),
),
),
),
'view_manager' => array(
'template_path_stack' => array(
'security' => __DIR__ . '/../view',
),
),
);
I had the same problem while following the skeleton application tutorial (Getting started: A skeleton application). Whenever I would go to the album url in the browser (ZendSkeletonApplication/public/album in my case), I would get a 404 error page but no details on why I got the 404. It wasn't clear to me how I would be able determine why I was getting the 404 when I had double checked everything and was pretty sure I copied and configured the Album module properly. It turned out that I was missing a slash in my route (module.config.php). For example I had 'route' => 'album[/:action][/:id]' instead of 'route' => '/album[/:action][/:id]'.
I was only able to figure it out by intentionally causing errors by misspelling things like making the 'Album\Controller\Albums' instead of 'Album\Controller\Album'in the invokables value, this would cause a stack trace to display which then showed the ZF2 classes that where called on the request. I would continue to misspell, test, and then correct each part of the module.config.php until I was given a clue to what part of the configuration was causing the error.
I'm pretty sure this was not the best way to debug an application's configuration.
There is few things that need to be make sure is:-
You have to add your module in
application.config.php (which you are saying you done it.)
Security\Controller\Security has to be same in default too (which you already has)
One more thing is Your folder structure....
-
Just to doulbe check you have a /MODULE/src/MODULE/Controller/CONTROLLER_FILE_NAME.php
I hope that helps..
I know it is an old post. However another thing to make sure you have in the modules top directory (same directory as the Module.php file) is the "autoload_classmap.php"
file with "<?php return array();?>" inside of it.
A simple tip to know whether your rule has already added correctly to the routes or not, you may check the routes value in the config file inside any working module, as following:
$config = $this->serviceLocator->get('config');
var_dump($config);
I use the module user
http://yiiframework.com/extension/yii-user/
then open localhost/testdrive and get an error - trying to get property of non-object
on line - array('url'=>Yii::app()->getModule('user')->loginUrl,
did everything according to instructions from the link
Maybe you should add 'class' parameter to 'user' to configuration in main.php, ie:
'components'=>array(
'user' => array(
'class' => 'application.components.WebUser',
'allowAutoLogin' => true,
'loginUrl' => array('/ua/user/login'),
)...
I figured out why this was happening to me, too. I had put the block at the end of main.php. If you put it at the beginning, the problem goes away.
