Freqently Asked Questions
License and domains

A license is valid for an unlimited period of time on one single Magento installation.

If you use more than one Magento installation, you will have to buy a separate license for each one.

If you run several domains on the same Magento installation, you will need only one license for all of them.

Although your license doesn’t have a limited period of validity, your support period does. By purchasing an extension, you’ll be granted a 6-month support period for free. Passed this period, you will have to renew your Support plan (see FAQ: How to extend my support period?).

You can pre-register your live domain to your license in advance.

Thanks to this option, you'll be able to get the extension ready to use on your domain before it goes live.

To pre-register your production domain: 

  1. Go to:
    mY accountLicenses & DOwnloads
  2. Click on  next to the extension you want your domain to pre-register on.
  3. Click on the link at the bottom of the page saying:
    Do you want to pre-register your domain in order to be ready to go live?
  4. Finally, enter your domain name and click on pre-register now .
Attention, this doesn't mean your license is activated. You'll still have to activate it on your new domain when the extension is installed. 

One license is valid for an unlimited period of time on one Magento installation only.  

It is possible, however, to extend or transfer your license in 2 cases: 

  • If you'd like to add your testing environments to your license.
    In this case, it is possible to extend your license to an unlimited number of domains for free.
    For example or
  • If you want to transfer your license to another live domain.
    In that case, the support period for your license must still be active.

To be able to use Quantity Switcher on both your production and testing environments, follow the instructions below:

  1. Download Quantity Switcher.
    (see FAQ: Extensions download)
  2. Install Quantity Switcher on your production environment.
    (see FAQ: Extensions installation)
  3. Activate the license.
    (see FAQ: Extensions activation).
  4. From your Magento admin panel, enter your current Activation Key in:
  5. Save your configuration.

Now that you can use Quantity Switcher on your production environment, repeat the same steps as above on your testing environments.

The only difference this time: a notification will appear in your Magento admin

You will be given a choice between:

  1. buy a new license now
  2. add this domain to my license

Click on Add this domain to my license.

A transfer request will then be sent to our team within an hour.

Once the request is taken care of, you will receive a confirmation email.

If your transfer request is accepted, you can use Quantity Switcher on both environments at the same time.

The order in which you activate your license on your domains does not matter.
You can start with your staging/dev/local environment or with your live domain, the process will be the same.

Good Extension

i have used Extension very Useful Qty Switcher Extension.


12th July 2015

Works on Magento 1.9

An addendum to a previously review:
"Works with the default theme.
You need to copy layout/qtyswitcher.xml and template/qtyswitcher/qtyswitcher.phtml from the default to your template to make it work."
And copy skin/frontend/default/default/qtyswitcher folder to your template to make it work


16th December 2014

works with issues - CE 1.9.1

This very outdated (2012 common!) extension is working by copying the right files to the proper template (see review bellow mine) but would still create some compatibility issues with different proper developed extensions. So in my case it is a NO. :(

Works on Magento 1.9

Works with the default theme.
You need to copy layout/qtyswitcher.xml and template/qtyswitcher/qtyswitcher.phtml from the default to your template to make it work.

1.9 not work

Same as other customers, this extension doesn't do anything even with the default template.

Works perfectly

I used this extension on 1.8.1 and it works flawlessly, really helped me a lot to implement quantity switching quickly.


4th August 2014

Don't work on Magento 1.9

In the description is showing:
Compatible with: 1.2, 1.3, 1.4,, 1.4.2, 1.5, 1.6, 1.6.1,, 1.7, 1.8, 1.8.1, 1.9
I don't now if you provide this info or was added by magento connect when 1.9.0 released. But in my magento 1.9 with 'rwd' theme nothing changes when install this extension. Wyomind's reply : This module works well with magento 1.9, you just need to move the module's layout and templates from the default theme to the rwd theme.

Can not disable per store configuration

Extension does not "disable" when told to in the store configuration. This is a headache.

Fix for broken button

If your button disappears or shown only a small part of it, put another set of span tags around the button code in qtyswitcher.phtml, like this:
<button onclick="productAddToCartForm.submit(this)" class="button btn-cart" title="Add to Cart" type="button" id="addToCartButton"><span><span><?php echo $this->__('Add to Cart') ?></span></span></button>
Anyway, I'm not sure if it's compatible with AJAX Cart. Please come back with a fix for this.
Thank you!
