My setup
I have two modules installed:
one takes an id and builds a product collection from this using the id to lookup an attribute-value pair (mod1)
The other offers a way of narrowing a search down (mod2)
The true url I am on is /mod1/page/view/id/<id#>
Desired outcome
To be able to pass the attribute-value as a hidden field to the second module
Question
How do I access the object and functions from mod1 when I'm in the layout file for mod2?
If more information is required, please let me know.
The way the module needed to be loaded was as follows:
Mage::registry('mod1_type');
Where in the controller this had been set:
$mod1Type = Mage::getModel('mod1/type')->setStoreId(Mage::app()->getStore()->getId())->load($mod1TypeId);
Mage::register('mod1_type', $mod1Type);
Then I could use the defined methods normally.
This may be an overly specific issue, should I just delete the question?

As the title suggests my question is pretty simple.
Is there a way to count the total number of active module instances of a specific type/kind in Joomla (with a specific module name)?
I know how to count modules in a specific module position using JModuleHelper::getModules, but that is not what I want.
I simply need to count all active modules instances of a specific type/kind.
Does anyone know how to do this (without having to do a manual MySQL query)?
I do not know if there is an official joomla way, but you can do it by having an sql query looking at
#__modules
table.
Check out this table and you will find out how easy it is.
An example sql would be:
select count(id) from #__modules where module = 'mod_login'
As far as i know there is no joomla method for this. I would recommend (if it has to be done) either
using a crawler to go through all pages of the site counting the instances.
or using a script which goes through the template php files and the database to find all active instances.
Both these methods might not be 100% reliable due to unexpected circumstances (like module being included in article or module included only after a button is clicked on) but could work if you know your site well enough.
Unfortunately there does not seem to be such a function in Joomla.
In my case I needed this to tell me whether or not a instances of this module was > 0 or not.. and my alternative solution was to simply make a module-specific function and then in the module php file check if function is already loaded.
I need to edit a page on prestashop, I've found that code
<ul id="idTab2" class="bullet">{$agencies->content}</ul>
And where should i search for that $agencies variable ?
I have found the text which is being displayed into that place in CMS.
However I'd that variable need to be define somewhere, am I right ? Anyone knows where should i search for that ? I'm new to prestashop.
Why am i asking for this ? I need to add another page for example
<ul id="idTab2" class="bullet">{$test->content}</ul>
- but I can't just simply add another page called test.
The {$agencies} variable is being set in a object derived from either the Controller or Module classes but to be honest it looks like you're working with code that has been customised (via a class override or a module) making it impossible to provide a definitive answer to your question without knowing more detail.
If you can locate the term 'agencies' in a file located under \controllers, \modules or \override in your installation, then you will be closer to finding your answer. It will be contained in a function call similar to:
$this->context->smarty->assign('agencies' , [some-variable]);
Note that the parameters to the function may also be passed as an array for multiple assignments.
I have used this module creator to get an custom attribute (which takes the type 'file').
http://www.silksoftware.com/magento-module-creator/
This works and can be seen in the admin area. I also have other custom attributes for customers which I have used this tutorial to create:
http://www.fontis.com.au/blog/magento/know-more-about-your-customers-adding-custom-signup-attributes
This also works. The reason I used the module creator was because I was unsure of how to make the input type as 'file'.
The attributes created through the fontis tutorial can be displayed as needed on the front end (which was only needed in the registration form).
The problem I'm having is in the custom area in the logged in accounts area on the front end. What I need is to retrieve the value of the 'file' attributes which was created in the module creator. Could anyone point me in the right direction of how to display these please? I have tried getAttributeName but this is not working.
Thank you.
If you post the code from your custom module we could help you more.
Meanwhile, here is some info that could help you:
Whenever you store something in the DB using a module, there is a Model class (that allows you to access the necessary data)
You can find the class name by looking in your modules etc/config.xml file
In the file look for section named <models>
The sub nodes of <models> is the name of the namespace (see below)
The sub node of your 'namespace' called <class> contains the rest of the info you will need
Next you need to call the Model with Mage::getModel('namespace/class_name')->load($id); to get a collection of all the custom attribute records that are in the system
To break this down in to manageable pieces:
Let's assume this is what your config.xml contains:
<models>
<customattribute> // this is your namespace
<class>Mycompany_Customattribute_Model</class> //this tells you wher to find your model files
<resourceModel>customattribute_resource</resourceModel>
</customattribute>
...
</models>
This means that your 'namespace' is 'customattribute'.
Next you need to find the file that contains your Model.
In this case we look at the <class> node to give us the file location (in this case app/code/local/Mycompany/Customattrbute/Model), now we need to go there and see the file that is there (let's say it's called 'File.php')
To get all the data we call the follwoing function:
Mage::getModel('customattribute/file')->load();
This will give us all the data.
If we want to narrow it down we can use the following function:
Mage::getResourceModel('customattribute/file')->addFieldToFilter('name_of_filed_in_db', 'value_we_want');
Improving on this question:
Is it good practice to add own file in lib/Varien/Data/Form/Element folder
The accepted answer shows how to extend a Varien form element, but this will not work if you want to package it into a custom module.
What would be the proper method of extending the Varien form element in a module? A simple XML setting I'm hoping?
Update:
Thanks Vinai for the response. Although that does work, I was hoping to extend the form element somehow. My extension is using the base File form element to allow administrators to upload files to categories. So, I'm not directly adding the form elements to the fieldset myself.
I suppose it's possible to to check for the file input on my category block on the backend: Mage_Adminhtml_Block_Catalog_Category_Tab_Attributes , and then change the form element if it is 'file' to 'mycompany_file' -- but this seems like a workaround.
Is there an easier way? Thanks again Vinai.
On the Varien_Data_Form instance you can specify custom element types like this:
$fieldset->addType('custom', 'Your_Module_Model_Form_Element_Custom');
Then, add your element with
$fieldset->addField('the_name', 'custom', $optionsArray);
If you are using a form without fieldsets you can do the same on the Varien_Data_Forminstance, too.
EDIT: Expand answer because of new additional details in the question.
In the class Mage_Adminhtml_Block_Widget_Form::_setFieldset() there is the following code:
$rendererClass = $attribute->getFrontend()->getInputRendererClass();
if (!empty($rendererClass)) {
$fieldType = $inputType . '_' . $attribute->getAttributeCode();
$fieldset->addType($fieldType, $rendererClass);
}
Because of this the attribute frontend_input_renderer on the attributes can be used to specify custom element classes.
This property can be found in the table catalog_eav_attribute, and luckily enough it isn't set for any of the category image attributes.
Given this, there are several ways to apply customizaton.
One option is to simply set the element class in the table using an upgrade script.
Another would be using an observer for the eav_entity_attribute_load_after event and setting the input renderer on the fly if the entity_type_id and the input type matches.
So it is a little more involved then just regular class rewrites in Magento, but it is quite possible.
You don't necessarily need to have a file in the lib/Varien/ directory in order to extend it. If you needed to add an element to that collection, you should be able to extend one of the Elements in your app/code/local module. The answer to the question you referenced seems to also indicate this is the case. I would create your custom field, extending its highest-level function set (i.e., lib/Varien/Data/Form/Element/File.php).
If you want to override the Mage_Adminhtml_Block_Catalog_Category_Tab_Attributes block, then you should extend that block in your module and then reference the new one. You may wish to extend the block using an event observer rather than an XML rewrite, for compatibility purposes.
I created a module with an observer for the sales module with event hook ‘sales_order_shipment_save_after’ ,
My module has the following files
Company/Modulename/etc/config.xml
Company/Modulename/etc/system.xml
Company/Modulename/Model/Observer.php
there are four fields in the modules admin configuration fields
I want to get those saved data in the Observer class.
using $this->getConfigData(’password’); gives a
Call to undefined method
error
Any suggestions?
Magento uses a static method on the global Mage application object to get configuration values
$config = Mage::getStoreConfig('section_name/group/field'); //value
$config = Mage::getStoreConfig('section_name/group'); //array
An amendment to Alan's completely correct answer.
Along with path as first parameter, getStoreConfig also accepts storeid as second parameter(optional).
Well, this is useful when you want to retrieve store-wise values.
Alan has mentioned this point in his own tutorial. I guess, he has not mentioned here just because OP has not mentioned this requirement in his question.
Please refer this
In a shipment module I can use $this->getConfigData for fields in system.xml, but in another kind of modules sometimes not, e.g. extends Mage_Core_Model_Abstract, than I must use getStoreConfig. So the answer is you don't have to use always getStoreConfig. But I don't know why ...
Answer: getConfigData is just defined in a shipment class and uses getStoreConfig too. A little confusing that some functions are extra defined and unneeded in fact ...
