How to get the context and context id in Moodle 2.9.1.
Currently I am in a block : Question Paper
In form submission action page I need the context id. I don't know how to get the context is inside a block (or module). My code is look like this:
question_action.php
require_once(dirname(dirname(dirname(__FILE__))).'/config.php');
require_once(dirname(__FILE__).'/locallib.php');
global $DB, $CFG;
require_once("$CFG->libdir/resourcelib.php");
if(isset($_GET['id'])){
$cid = $_GET['id'];} //course id
if(isset($_GET['poolid'])){
$paper= $_GET['paper'];} //question paper id
How I find the context and context id here..
Inside the block get_content() function, you can get the contextid from $this->context->id.
If you have an extra PHP page within your block, you will need to make sure that any links have some sort of identifier added as a parameter (that could be the courseid, the blockid or the contextid).
Assuming all your links have the courseid at the end of them (probably the most sensible choice), on the page itself you can write:
$courseid = required_param('id', PARAM_INT); // Do not use $_GET directly.
$course = $DB->get_record('course', ['id' => $courseid], '*', MUST_EXIST); // Optional, but you often need the course object.
$context = context_course::instance($courseid);
$contextid = $context->id;

I am still new to Zend Framework and confused about a few concepts.
I have built a POST form and attached a unique Id to the URL at the end of the form. I now want to collect that Id when the form is submitted but I am unclear how to do that
I will show you want I have done:
Below is the function that renders the form from my controller page to the view. You will note that I have fed into the parameter, for the form, a return Action address with the ID
$action = "{$this->view->baseUrl()}/sample-manager/process-price/{$sampleId}";
$this->view->Form = $model= $this->_model->createForm($action);
The function to receive the post is below. However, I want to collect the Id that should have come back with the post return values, but I have no idea where to find it or how to attach it.
public function processPriceAction()
{
$this->requirePost();
if($this->_model->processTieredPriceForm($this->view->form, $this->getRequest()->getPost()))
{
$this->_helper->FlashMessenger('Changes saved');
return $this->_redirect("/product-ecommerce/{$this->_model->getProduct()->id}");
}
else
{
return $this->render('index');
}
}
In summary, when a post is returned, does the return address come with the post in Zend Framework?
Could you not supply the id into the construction of the form and assign it to a hidden element? For example, in your controller:
$action = "{$this->view->baseUrl()}/sample-manager/process-price";
$this->view->Form = $model= $this->_model->createForm($action, $sampleId);
In your form model (not provided so best guess here):
$sampleId = new Zend_Form_Element_Hidden('sampleId');
$sampleId->setValue($sampleId);
$form->addElement($sampleId);
Then once the form is posted, you should be able to get the sample id in your controller in the standard way:
$sampleId = $this->getParam('sampleId');
The answer depends a bit on how your routing is setup. If you're using the default setup, after the action name the default route allows for key/value pairs of additional data. So, you might have more luck with a URL like this:
{$this->view->baseUrl()}/sample-manager/process-price/id/{$sampleId}
That'll put your sampleId in a named parameter called 'id', which you can access in your controller action with $this->_getParam('id').
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')?>
I don't know too much about Joomla, but I'm trying to work with a Menu on a Joomla site. In the Database I can see a column called params in the menu table, and it has some data I need. The params column has this data:
categories=446
feedLink=1
fusion_item_subtext=
fusion_columns=1
fusion_customimage=
splitmenu_item_subtext=
page_title=
show_page_title=1
pageclass_sfx=
menu_image=-1
secure=0
I know I can do a mysql query, get that column and parse the value using string manipulation/regex, but that doesn't sound like the right way.
I have seen some code in Joomla that looks like:
$cid = $params->get('secure');
Does Joomla have a special way to query and return objects so that these params are accessible with this type of syntax?
Right way is to use JMenu::getParams method
$app =& JFactory::getApplication();
$menu =& $app->getMenu();
$params = $menu->getParams($menuItemId);
$params->get('paramName');
Yes, Joomla does have special way of getting the parameters in an easily accessible object based on JObject.
you can get the entire site menu with this
$menu = JFactory::getApplication()->getMenu();
$item = $menu->getActive(); // will get active menu item. can use getItem() instead to get specific item
$item->get('parmName');
This is not exact code, more like pseudocode. This will get you on the right track...
Helpfull Stuff:
Joomla Framework API
JMenu Documentation
first you get a JApplication instance like this
$app = & JFactory::getApplication();
or for joomla 1.5 use:
global $mainframe //to get JApplication object
get JMenu instance like this:
$menu = $app->getMenu();
you can get active menu params or any other menu params like this
$active = $menu->getActive(); //get active menu
$menuInstance = $menu->getActive($Itemid); // to get Itemid use JRequest::getInt('Itemid', 0);
here you have an StdClass object with params field inside, now u use JParameter class like this
$menuParams = new JParameter($menuInstance->params);
here you have it, to get any parameter you want:
$someParam = $menuParams->get('some_param', 'default');
For example:
I need to retrieve a set of male User's IDs, First Names, and Last Names, but nothing else.
So I have a function in UserMapper called fetchAllMaleUsers() that returns a set of User entities.
i.e:
public function fetchAllMaleUsers() {
$select = $this->getDbTable()
->select()
->from($this->getDbTable(),
array('ID', 'FirstName', 'LastName'))
->where('Gender = ?', 'M');
$resultSet = $this->getDbTable()->fetchAll($select);
$users = array();
foreach ($resultSet as $row) {
$user = new Application_Model_User();
$user->setId($row->ID)
->setFirstName($row->FirstName)
->setLastName($row->LastName);
$users[] = $user;
}
return $users;
}
Does this function belong in the mapper layer?
Is it ok to only set the Id, Firstname, and LastName of each User entity?
1) Perfectly fine for the mapper/Gateway or however you call it.
2) You can do but i highly disencourage this. Why? Later on in your application you can't tell from where you did get the model. So you'd have to check if a value is set in your model each time you're not sure if it is set or you'd need some autoloading stuff for missing values (which is as worse as missing stuff). Another reason is that you can't reuse the function for other porposes where you might need other properties of the user model. Last reason afaik is, that a model represents the complete entity at any time, not parts of it. And there's no real reason why not to load all fields (beside references to other entities why should be autoloaded anyways).
Along with Fge's reply I believe that $resultSet should already be returning values of type Application_Model_User. If not, you may need to set $_rowClass in Application_Model_DbTable_User.
I have a form, created with Zend_Form, with method = GET used for searching records with elements as below:
[form]
user name [input type="text" name="uname"]
[input type="submit" value="Search" name="search"]
[/form]
After form is submitted all the GET parameters along with submit button value are appearing in the url.
http://mysite.com/users/search?uname=abc&search=Search
How to avoid submit button value appearing in the url? is custom routing the solution ?
When you create your element, you can simply remove the name attribute that was automatically set at creation
$submit = new Zend_Form_Element_Submit('search')->setAttrib('name', '');
Or inside a Zend_Form
// Input element
$submit = $this->createElement('submit', 'search')->setAttrib('name', '');
// Or Button element
$submit = $this->createElement('button', 'search')->setAttribs(array
(
'name' => '', 'type' => 'submit',
);
When a form gets submitted, all of its elements with their names and values become a part of a GET / POST - query.
So, if you don't want an element to appear in your GET - query, all you need to do is to create this element without a name. That's probably not the best approach, but since we're talking about the 'submit' element, I guess it doesn't matter that much.
Looking at Zend_View_Helper_FormSubmit helper, you can see that it's creating the 'submit' element and setting its name. So, the possible solution would be to create your own view helper and use it for rendering the 'submit' element instead of the default helper.
You can set a custom helper with
$element->setAttribs( array('helper' => 'My_Helper_FormSubmit') );
Then build your own form element class and remove the name attribute from the element with preg_replace. The beauty of it is, it will not interfere with the other decorators.
So the something like this:
class My_Button extends Zend_Form_Element_Submit
{
public function render()
{
return preg_replace('/(<input.*?)( name="[^"]*")([^>]*>)/', "$1$3", parent::render(), 1);
}
}
You can remove name attribute for submit button in javascript.
jQuery example:
$('input[name="submit"]').removeAttr('name');
In the controller that represents the form's action, redirect to another (or the same controller) only including the relevant params.
Pseudocode:
$params = $this->getRequest()->getParams();
if isset($params['search'])
unset($params['search']);
return $this->_helper->Redirector->setGotoSimple('thisAction', null, null, $params);
handle form here
This is basically the same idea as Post/Redirect/Get except that you want to modify the request (by unsetting a parameter) in between the different stages, instead of doing something persistent (the images on that Wiki-page shows inserting data into a database).
If I were you, I would leave it in. IMO it's not worth an extra request to the webserver.
