Magento-1.9 – Difference Between Mage::getStoreConfig() and getConfigData()

magento-1.9

Please explain me what is the difference of

$this->getConfigData('xyz') and Mage::getStoreConfig('abc/xyz/hfc').

What is the difference of both function.

Best Answer

When you use Mage::getStoreConfig('abc/xyz/hfc') then you need to pass section name, tab name & field Name. so It will fetch value for that field.

But If Suppose you have payment module and you have more then 100 Fields so each time you can not give whole path. In your Module you can create one method like as below. so you need to just pass the key and it will create path using function.

public function getConfigData($key)
{
    return Mage::getStoreConfig("catalog/custom_options/$key");
}

It it's very easy for you to identify.

In Magento Release Notes They also mention this Line Made fetching payment methods sort order properly: via getConfigData() rather getStoreConfig() (optimization for 3rd-party customizations).

Magento 1.9 Validation – Difference Between Validator and Validator.validate()

Take a look at js/prototype/validation.js

.....
onSubmit :  function(ev){
    if(!this.validate()) Event.stop(ev);
},
validate : function() {
    var result = false;
    var useTitles = this.options.useTitles;
    var callback = this.options.onElementValidate;
...

Then take a look at js/mage/adminhtml/form.js or (/js/varien/form.js)

varienForm.prototype = {
    initialize : function(formId, validationUrl){
        this.formId = formId;
        this.validationUrl = validationUrl;
        this.submitUrl = false;

        if($(this.formId)){
            this.validator  = new Validation(this.formId, {onElementValidate : this.checkErrors.bind(this)});
        }
        this.errorSections = $H({});
    },

then

var loginForm = new VarienForm('loginForm', false);

validator is a variable (see this.validator = new Validation..) that store the validation instance.

function onepageLogin(button)
{
    //check to see if the validator instance exist and programmatically validate the form
    if(loginForm.validator && loginForm.validator.validate()){  
        //disable the button to prevent multiple click             
        button.disabled = true;
        //submit the form since all the required field are entered 
        loginForm.submit();
    }
}

Magento – the difference between (‘catalog/layer’) and (‘catalog/category’)

There are 2 different objects.
A category model is the mapping of a model to the category tables.
A category has a many to many link to the products.
A category usually appears in the top navigation menu.

A layer model does not have a table behind it and it is in charge of the layered navigation.
A layer model has filters associated to it and one of the filters is the list of subcategories for the current category you are viewing.

A layer model does not need a category to display products. It is also used in search results.
