Magento Extension: Estimated Delivery
Today I present you a little commercial Magento 1.x extension I have been working on with my team at SGH:
SGH_EstimatedDelivery ($79.00)
It calculates estimated delivery date and shows the customer how much time is left to get the order on this date. This information can be shown on the shopping cart and on product pages:

Filtering Magento Collections: addFilter() vs. addFieldToFilter()
There was an interesting question on StackExchange recently that did not get much attention:
Magento collection has two methods for filtering:
Varien_Data_Collection_Db::addFieldToFilterVarien_Data_Collection::addFilterSeems that both methods add where condition to
Zend_Db_Select. And what advantages doesaddFilterbring? When should I use it instead ofaddFieldToFilter?
I had to dig a bit into addFilter myself because I was only familiar with addFieldToFilter and here is what I found:
Link to the question: addFilter vs addFieldToFilter

The week on StackExchange #12 / 2016
Here’s the next update, this time only with new, hopefully interesting answers on Magento StackExchange.
Magento 2
- Which compilation commands are needed in developer mode and when? received a few useful answers. The +150 bounty for the best canoncial answer is still open.
- I shared some thoughts about efficient usage of builders: Use preconfigured builders (e.g. for SearchCriteria) in Magento 2 Thanks to Vinai for helping out here!
- Do you miss good old local code pool overrides? Read this: Override abstract class in Magento 2
- Confused with the mixture of
$(),$$()andjQuery()in JavaScript? What does $$ in javascript of Magento 2 mean?
Magento 1
- Saving CMS pages and blocks programmatically (e.g. in a setup script) can be tricky: Saving CMS block/page from collection removes store ID’s
- Somebody couldn’t overwrite template via xml added by external module – a common pitfall with the layout XML when block names are reused.
- And a quickie, which events to observe to react on cart changes: Is there an event that fires when the cart/quote is empty?
Design Patterns for Framework Agnostic Extensions/Plugins – Autoloading
Part 5 of my blog series on integer-net.com about framework independent code is out: Using Advanced Autoloading. This one is only relevant for the integration of legacy applications that do not use composer autoloading yet (Magento 1).

The week on StackExchange #11 / 2016
Here’s the next update with new, hopefully interesting, questions and answers on StackExchange.
New Answers

- What happened to the
customer_logged_inandcustomer_logged_outlayout handles in Magento 2? Magento2. Layout Handle customer_logged_in - If you want to set up a password protected staging system with Varnish, here you go: Setting up Magento Staging Environment with Restricted Access

New Questions
- After a day of Magento 2 develoment with JavaScript, I shared the frustrating summary on Twitter, which attracted some attention:
Today's Magento 2 workshop: 3h installing, 1h explain DI, plugins & Co, 2h coding & debugging, 2h waiting for static content to be deployed

Looks like I am not alone with this experience but it’s not really how it is supposed to be. This lead me to the question Which compilation commands are needed in developer mode and when? - There seems to be a bug in certain Magento versions with order reports and timezones but I could not quite pin it down yet: Magento Reporting – Is it bucketing by UTC?
The week on StackExchange #10 / 2016
Here’s the next update with new, hopefully interesting, questions and answers on StackExchange.
New Answers
- Marius attended my question about generated PHTML files in Magento 2 and also found out when they are used: When and how are phtml templates generated in view_pre geprocessed?
- I found a bug in the JavaScript function
Mage.Cookies.clear(). It looks like it never worked, and actually it is not even used in the core. Here I describe the fix: Mage.Cookies.clear() not working - In How to limit characters in system.xml for textarea in magento I show how easy validation of inputs in the Magento configuration is possible (Spoiler: You don’t need jQuery).
- There is an interesting optimization opportunity if you don’t need URL rewrites for products: How do I get Magento to always give the /catalog/product/view/id/ style url for products?
- A problem that other Magento users who try to use Varnish with HTTPS might know as well: https redirection loop even with X-Forwarded-Proto
New Questions:
- I asked myself if it makes sense as an extension developer to add the whole Magento repository as dev-requirement: Magento 2 as composer dev requirement for extensions – the answer is as often “it depends”. It was already interesting to get insights from companies like Aheadworks and Fooman.
- There is still no answer to How does translation scope work in Magento 2? and I fear it’s because it cannot be answered. But to be sure, I offered a bounty: +50
