I want to use htmlpurifier on my website, but can't figure out how to load my filter in the view. I've added my filter the way described in the first answer here.
I want to be able to call it from my view with something like $this->filter($content) Any suggestions how I do that?
It is a two step process:
Write an actual Zend_Filter implementation of HTMLPurifier (done, answer in the question you mentioned)
Write a view helper
It will look like this:
class My_View_Helper_Purify extends Zend_View_Helper_Abstract
{
public function purify($value)
{
$filter = new My_Filter_HtmlPurifier();
return $filter->filter($value);
}
}
Don't forget to add your custom view helper path:
$view->addHelperPath(
APPLICATION_PATH . '/../library/My/View/Helper',
'My_View_Helper_'
);
And later in any of your view scripts:
<?= $this->purify($text) ?>

Can anyone here know how to use the processUpload_postProcessAction hook in my extension?
I have created a hook folder and added a php file named class.tx_lms_tcemain.php
I have added the following lines in my extension's ext_localconf.php
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php']['processUploadClass'][] = 'EXT:wr_dw_lms/hooks/class.tx_lms_tcemain.php:tx_lms_tcemain';
In the PHP file inside hooks folder contains following code:
<?php
class tx_lms_tcemain {
function processUpload_postProcessAction (&$filename, t3lib_TCEmain
$parentObject) {
$this->addFlashMessage(
'Blog created successfully!',
'Status',
\TYPO3\CMS\Core\Messaging\AbstractMessage::OK,TRUE
);
}
}
?>
This one does not work. My code is not getting executed. Can anyone here help me?
Try to write this in your ext_localconf.php
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_extfilefunc.php']['processData'][] = 'Vendor\WrDwLms\Hooks\Tcemain\';
Try to change your code in ext_localconf.php to
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php']['processUpload'][] = 'EXT:wr_dw_lms/hooks/class.tx_lms_tcemain.php:tx_lms_tcemain';
Note the "processUpload" instead of the "processUploadClass".
I'd recommend however you use proper namespacing:
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php']['processUploadClass'][] =
'Vendor\WrDwLms\Hooks\Tcemain';
Your Hook could look like this (put it in wr_dw_lms/Classes/Hooks/):
namespace Vendor\WrDwLms\Hooks;
use TYPO3\CMS\Core\DataHandling\DataHandler
class Tcemain {
public function processUpload_postProcessAction(&$filename, DataHandler $parentObject) {
....
}
}
Edit: as for the code you edited into your question ($this->addFlashMessage()) that of course cannot work if you do not implement the method in your class.
at the moment I´m working with a custom Silverstripe Controller with a Director rule:
---
Name: myroutes
After: framework/routes#coreroutes
---
Director:
rules:
'category/$Action/$Slug': 'Category_Controller'
The Controller looks like that:
class Category_Controller extends Page_Controller {
public function show($arguments) {
echo "Slug: " . $arguments->param("Slug");
}
}
When I open in the browser the URL http://mysite.com/category/show/mobile
then the output look fine like this: "Slug: mobile".
I just wonder how I can use a Category.ss Template from the Folder "themes/templates/Layout" to render the Output. Then of course the container html (with header/footer) from Page.ss should be included as well. Just as usual when you have a custom Page Controller/Class and a corresponding Template in the Layout Folder.
I just tried this:
public function show($arguments) {
echo $this->renderWith("Category");
}
It uses Category.ss for rendering the output, but there is no container html...
Thx for any help.
Regards,
Florian
you can also pass an array to renderWith(), and it will try through the array until it finds a template.
so lets say $this->renderWith(array('Category', 'Page'));
it will first look for a template called Category.ss, but will not find it (in the templates folder, not layout folder), it will then find Page.ss and use it.
Now it hits $Layout inside Page.ss and it checks the array again inside the Layout folder, it will now find the Category.ss, which is exactly what you where looking for if I got the question right.
if you do not want to do return $this->renderWith(); you can also just do return $this; and silverstripe will get the action you called and the class hierarchy of $this and use that as array for renderWith()
So if your classes are Category_Controller > Page_Controller > ContentController the array will look like this:
array(
'Category_show', // because your action is show
'Category',
'Page_show',
'Page',
'ContentController_show',
'ContentController',
)
(I am not a 100% sure if it also includes Page_show and ContentController_show.)
I need same 2 lines in all my controllers, each controller have its own init logic, but these two lines are common for all of them.
public function init()
{
$fm =$this->_helper->getHelper('FlashMessenger');
$this->view->messages = $fm->getMessages();
}
How can I avoid repeat code ?
Update:
Ok, the FlashMessenger was only an example, let's say I need write a log line in every action except for 'someAction' # 'someController'. So the new common lines should be.
$this->logger = new Zend_Log();
$writer = new Zend_Log_Writer_Stream(APPLICATION_PATH.'/../logs/log.txt');
$this->logger->addWriter($writer);
$this->logger->log('Some Message',Zend_Log::DEBUG);
The question is, where should I place these lines in order to avoid repeat them in all init() of each controller.
These lines should be placed at bootstrap?. If so: How can skip log lines for 'someAction'.
Or should I implement a 'BaseController' and make all my controller extend from it. If so: How can I Autoload it? (Fatal error: Class 'BaseController' not found) .
Just subclass the controller:
class Application_ControllerAction extends Zend_Controller_Action {
public function init()
{
$fm =$this->_helper->getHelper('FlashMessenger');
$this->view->messages = $fm->getMessages();
}
}
class IndexController extends Application_ControllerAction {
}
You may also achieve the same writing Controller Plugin.
Edit:
Front controller plugins are executed on each request, just like the Controllers and have the same hook methods:
routeStartup(): prior to routing the request
routeShutdown(): after routing the request
dispatchLoopStartup(): prior to entering the dispatch loop
preDispatch(): prior to dispatching an individual action
postDispatch(): after dispatching an individual action
dispatchLoopShutdown(): after completing the dispatch loop
I addition, you may check controller params to execute the code only on selected requests:
if ('admin' == $this->getRequest()->getModuleName()
&& 'update' == $this->getRequest()->getActionName() ) …
You can access your flash messages through (you dont need to send anything from your controller to your view, it's all automated)
$fm = new Zend_Controller_Action_Helper_FlashMessenger();
Zend_Debug::dump($fm->getMessages());
in you view, i would also recommand that you encapsulate this code in a view helper like it is shown on this site http://grummfy.be/blog/191
In your bootstrap:
protected function _initMyActionHelpers() {
$fm = new My_Controller_Action_Helper_FlashMessenger();
Zend_Controller_Action_HelperBroker::addHelper($fm);;
}
How can I avoid repeat code ?
Write your own custom controller, implement that in init method of that controller, and then extend all controllers in your app from your custom controller.
But approach with separate view helper as #Jeff mentioned (look at link) is often taken as a better solution.
In your controller do only:
$this->_helper->flashMessanger('My message');
and view helper will do the rest.
It's not the reason for creating new custom controller. Just add this line to all you init() methods.
$this->view->messages = $this->_helper->getHelper('FlashMessenger')->getMessages();
Is there some method that accepts inserting custom html without having to actually add form controls, even if they're hidden and making my html a decorator?
I'm looking for something like:
$this->addCustomElement( array(
'div',
'body' => '<p>inner text</p>'
) );
I need something short and quick, I don't want to create a new class or something overkill.
Well it's really as simple as this:
$note = new Zend_Form_Element('note');
$note->helper = 'formNote';
$note->setValue('<b>hi</b>');
$form->addElement($note);
But the problem is that when you submit the form, the form calls $note->isValid(), which overrides the value, so if there are errors with the form, the next time you display it, the custom HTML won't be shown. There are two easy ways to fix this, the first is to override isValid() in your Form class like this:
public function isValid($data)
{
$note = $this->note->getValue();
$valid = parent::isValid($data);
$this->note->setValue($note);
return $valid;
}
But personally I find this kinda hackish way, and prefer the second option. That is to write a very simple class (this should really be part of Zend itself, I have no idea why it isn't, since it includes a formNote view helper, but no element that uses it):
class My_Form_Element_Note extends Zend_Form_Element_Xhtml
{
public $helper = 'formNote';
public function isValid($value, $context = null) { return true; }
}
Then you just have to do:
$note = new My_Form_Element_Note('note');
$note->setValue('<b>hi</b>');
$form->addElement($note);
And everything will just work.
Other options include doing some black magic with decorators, but I really recommend you to not go down that path.
Also note the AnyMarkup Decorator.
I'm trying to add some functionality from a plugin I have made into a Wordpress theme but I am having little joy. The documentation doesn't really help me solve the problem so perhaps someone here can help.
I have a plugin in Wordpress that is activated and working fine. The class for this plugin has a function called generateHtml which I would like to access from a Wordpress Theme. But whatever I try, I cannot seem to access my plugin's code.
Can either give me a summary of what I need to do to get a theme accessing code from a plugin and/or point out there I am going wrong in my code:
Plugin:
<?php
/** Usual comments here **/
if (!class_exists("ImageRotator")) {
class ImageRotator {
private $uploadPath = '';
private $pluginPath = '';
private $options;
function __construct() {
$this->uploadPath = dirname(__file__).'\\uploads\\';
// add_shortcode('imagerotator', array(&$this, 'generateHtml'));
}
// Various functions for plugin
function generateHtml() {
echo '<p>Hello World</p>';
}
}
}
/**
* Create instance of image rotator
*/
$imageRotator = new ImageRotator();
/**
* Create actions & filters for Wordpress
*/
if (isset($imageRotator)) {
// Actions
add_action('admin_menu', array(&$imageRotator, 'createMenu'));
add_action('admin_init', array(&$imageRotator, 'registerSettings'));
add_action('imagerotator_show', array(&$imageRotator, 'generateHtml'));
}
Portion from theme header page:
<?php if (isset($imageRotator)) {
$imageRotator->generateHtml();
} else if (isset($ImageRotator)) {
print_r($ImageRotator);
} else {
echo '<p>Nope!</p>';
}
if (function_exists("imagerotator_show")) {
echo 'Function found';
} else {
echo 'Function NOT found';
}
?>
Currently all I ever see is "Nope" and "Function NOT found". Thanks for any input.
Lee,
For starters, "imagerotator_show" is not a function; it's the name of a type of action. When you use the add_action() function, Wordpress just adds your method to the list of functions/methods to call when a particular action is triggered. Thus your second test will always respond with 'Function NOT found'.
The most likely cause of the first problem is failing to declare the method you want to call as a public method. You're also making the code harder than it needs to be.
The best practice I've seen for declaring methods and registering hooks from a class looks something like this:
if ( ! class_exists( 'Foo' ) ):
class Foo {
function __construct() {
add_action( 'hook_name', array( &$this, 'my_hook_implementation' ) );
}
function my_hook_implementation() {
// does something
}
public function my_special_method() {
// does something else
}
}
if ( class_exists( 'Foo' ) ):
$MyFoo = new Foo();
This allows your class to keep all of its implementation details private. When you need to call my_special_method(), you do it as follows:
$MyFoo->my_special_method();
#andrew since I can't comment I thought I would answer your ancillary question. See:
http://net.tutsplus.com/tutorials/wordpress/create-wordpress-plugins-with-oop-techniques/
Where it is explained that when defining a callback function from an object you have to use the array function. It's basically saying get the function 'my_hook_implementation' from the object $this and use it as the callback parameter to the add action hook. It is because you defined the function within the scope of the object and you have to define the scope in order for PHP to know what function you are talking about. The scope being the object referred to by the variable $this.
You just need to use do_action() function, inside your theme.
If you want the function generateHtml to appears inside your header.php you just need to open the header.php file and paste <?php do_action('imagerotator_show'); ?> where you want and then your function will be called there.
