I'm trying to get started with Zend Framework , followed the quickstart project and am trying to start a new module of my own.
Am trying to implement view helpers and I keep getting the following message:
Message: Method formDate does not exist
Last entry at the stack trace:
0 D:\work\quickstart_zend\application\views\scripts\users\register.phtml(38): Zend_Form_Element->__call('formDate', Array)
I have the following file structure:
quickstart_zend
+ application
+ configs
+ controllers
[...]
+ views
+ helpers
+ scripts
[...]
+ library
+ Application
+ Form
+ Element
Date.php
+ View
+ Helper
FormDate.php
+ public
I have added in my public/Bootstrap.php this method:
protected function _initActionHelpers()
{
Zend_Controller_Action_HelperBroker::addPath(APPLICATION_PATH.'/../library/Application/View/Helper', 'Application_View_Helper');
Zend_Controller_Action_HelperBroker::addPrefix('Application_View_Helper');
}
I have also added in my application.ini:
autoloaderNamespaces[] = "Application"
resources.view.helperPath.Application_View_Helper = APPLICATION_PATH "/../library/Application/View/Helper/"
And i have seen a version and also have tried with resources.view.helperPath.Application_View_Helper_, nothing seems to get it to work.
Of course, i have a Users.php form where i create a 'date' element:
// Add a dateOfBirth element
$element = new Application_Form_Element_Date('dateOfBirth');
$this->addElement($element);
Of course, i have a Users.php form where i create a 'date' element:
// Add a dateOfBirth element
$element = new Application_Form_Element_Date('dateOfBirth');
$this->addElement($element);
And in my view script, where the errors shows up:
<? echo $form->dateOfBirth->formDate() ?>
What am i missing to get it to work? :-( i've spent a day so far looking for solutions
You are receiving this error because there is no such method in Zend_Form_Element. I think you are trying to use your view helper to display in some way this form element, but if this is the case it is better to use form decorators. You can use the standard decorators or you can create a custom one. Check the documentation for more info - http://framework.zend.com/manual/en/zend.form.decorators.html
to properly use your view helper on that data you would use it like:
In your view (.phtml)
//a view helper should act on a piece of data and return something
//so I assume your formDate() helper takes a date value and reformats it.
<?php echo $this->formDate($this->form->dateOfBirth) ?>
assuming you assigned your form to the view in your controller using the standard:
$this->view->form = $form;

I'm having an issue displaying information returned from a custom class defined within a plugin's files, when using a shortcode. I'll write up some mock files that showcase my issue.
/wp-content/plugins/my-plugin/classes/my_class.php
<?php
class People {
public $api_url = "https://www.external-service.com/api";
private $api_key;
function __construct($key = null) {
if $(key) {
$this->api_key = $key;
}
function get_response() {
$path = $this->api_url . "?my_api_token=" . $this->api_key;
}
}
?>
/wp-content/plugins/my-plugin/my-plugin.php
<?php
/**
* all of the wordpress plugin comments
* ...
*/
require "myplg_options.php";
require "myplg_shortcodes.php";
The options page and menu is generated from myplg_options; it is functioning correctly (including using get_option to retrieve the saved option (in this case, the api key).
/wp-content/plugins/my-plugin/myplg_shortcodes.php
<?php
require "classes/my_class.php";
$options = get_option('myplg_settings');
$myplg = new People($options['myplg_api_key']);
$response = $myplg->get_response();
function myplg_list_result(){
echo "the shortcode is working!";
var_dump($options, $myplg, $respnose);
}
add_shortcode('myplg_list', 'myplg_list_result');
?>
Testing externally from wordpress, the class works and everything is fine and dandy. The plugin's option page sets and retains the single option perfectly; the shortcode actually registers and is usable from within a WordPress page/portfolio/etc.
The issue I'm having is that using var_dump, all three of those variables are dumped as NULL.
After doing some homework, I was able to determine that moving the three variable declarations inside the shortcode makes it work. It would seem to me, however, that doing that is not the best workflow, as I'd need to re-grab the option, instantiate a new class, and call the class' function for every shortcode.
Is there a way around this?
As mentioned in the comment it's because variables are function scoped. You may be better off using a Closure.
<?php
require "classes/my_class.php";
$options = get_option('myplg_settings');
$myplg = new People($options['myplg_api_key']);
$response = $myplg->get_response();
add_shortcode('myplg_list', function() use ($options, $response, $myplg) {
echo "the shortcode is working!";
var_dump($options, $myplg, $respnose);
});
I have setup in my MVC site a Session variable to carry ids to be used on any subsequent pages.
In my controller, var_dumping the session shows its there with the correct values but when I pass said values to the view and trying to echo them there, it comes up blank.
Any pointers as to whats going on to cause them to not appear.
Please note, the view is a partial view, not the main one.
Bootstrap session related code:
protected function _initSession(){
Zend_Session::start();
$SessAuto2Auto = new Zend_Session_Namespace('SessAuto2Auto');
$SessAuto2Auto->cityIds = "1,2,3"; // Hard code values for testing purposes
$SessAuto2Auto->IndustryIds = "3,4"; // Hard code values for testing purposes
}
Controller related code : ProductController.php
public function indexAction()
{
// .. Unrelated code removed for brevity
$response = $this->getResponse();
$response->insert('sidebar', $this->view->render('sidebar.phtml'));
// This code is dumping the values correctly
echo('<pre>');
var_dump($this->sessionAuto2Auto);
echo('</pre>');
// .. Unrelated code removed for brevity
$this->view->filterCity = $this->sessionAuto2Auto['cityIds'];
$this->view->filterIndustryIds = $this->sessionAuto2Auto['IndustryIds'];
}
View partial : sidebar.phtml
<?php
// This code does NOT show the value, comes up blank
echo($this->filterCity);
?>
If you are calling sidebar.phtml using the partial helper, partials have their own variable scope, they can only access variables which are passed in to them. You need to either include your session variables in your partial helper call:
echo $this->partial('sidebar.phtml', array(
'filterCity' => $this->filterCity,
'filterIndustryIds' => $this->filterIndustryIds
)
or use render instead (which uses the same scope as the other view scripts):
<?=$this->render('sidebar.phtml')?>
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 am trying to populate the values into check box. I want check box to be checked when there is value stored in database.
This is my code in form:
$form ['test_1'] = new Zend_Form_Element_Checkbox('test_1');
$form['test_1']->setLabel('test1')->setCheckedValue('1');
$form ['test_2'] = new Zend_Form_Element_Checkbox('test_2');
$form['test_2']->setLabel('test2')->setCheckedValue('2');
If there is value 1 in database i want first check box to be checked and if its 2 then 2nd checkbox needs to be checked.
What do i need to do in the controller.
Could anyone please help me on this issue.
The easiest way would be to fetch the values from the database as an array that maps to the form input elements, e.g. return a row like
array('test_1' => 'value of checkbox', 'test_2' => 'value of checkbox');
You could then simply call $form->populate($values) and let do Zend_Form do the setting, e.g. in your controller do
public function showFormAction()
{
$form = $this->getHelper('forms')->get('MyForm');
$data = $this->getHelper('dbGateway')->get('SomeTable');
$form->populate($data->getFormData());
$this->view->form = $form;
}
Note: the helpers above do not exist. They are just to illustrate how you could approach this. Keep in mind that you want thin controllers and fat models, so you should not create the form inside the controller, nor put any queries in there.
I have an action which is rendering some content via a layout.
I actually want to send this output in an email. What is the best way to achieve this in the Zend Framework?
I know I need to use the Zend_Mail component to send the email, but I'm unclear about how to attach the output of my action to Zend_Mail.
I've done some reading on the ContextSwitch action helper, and I think that might be appropriate, but I'm still not convinced.
I'm still new to Zend Framework. I'm used to using techniques like output buffering to capture output, which I don't think is the correct way to do this in Zend.
From your controller:
// do this if you're not using the default layout
$this->_helper->layout()->disableLayout();
$this->view->data = $items;
$htmlString = $this->view->render('foo/bar.phtml');
If you're doing this from a class that's not an instance of Zend_Controller_Action, you may have to create an instance of a Zend_view first, to do this:
$view = new Zend_view();
// you have to explicitly define the path to the template you're using
$view->setScriptPath(array($pathToTemplate));
$view->data = $data;
$htmlString = $view->render('foo/bar.phtml');
public static function sendMail($data = array(), $template = ''){
$html = new Zend_View();
$html->setScriptPath(APPLICATION_PATH . '/modules/default/views');
// assign valeues
if(count($data['Assigni'])){
foreach($data['Assigni'] as $assign){
$html->assign($assign['key'], $assign['value']);
}
}
// create mail object
$mail = new Zend_Mail('utf-8');
// render view //'scripts/newsletter/emailtemplate.phtml'
$bodyText = $html->render($template);
$mail->addTo($data['To']);
$mail->setSubject($data['Subject']);
$mail->setFrom($data['From'], $data['FromName']);
$mail->setBodyHtml($bodyText);
$mail->send();
}
when you dispatch the action, you can catch the event in postDispatch() method of plugin, that you can dynamically add to the stack from desired action. In that you recieve the contents of response by
//in action
//...some php code
Zend_Controller_Front::getInstance()->registerPlugin(new My_Plugin());
//in plugin
$htmlCode = $this->_response->getBody();
I can't give you a super-detailed answer, but if you want the full output (including the layout), I think you want to write your email function as an Action helper, and insert it at the PostDispatch hook of the Zend_Controller_Action->dispatch() loop.
See http://nethands.de/download/zenddispatch_en.pdf for the full Zend Framework Dispatch Process Overview.
If you don't need the layout included in your email content, then you could do this at many points, including by the use of a context switch, as you mentioned.
