For desktop websites I've configured Magento to have 3 columns on category pages due to which when I see it on mobile devices, it shows 2 products in a row and 1 product in next row and it repeats the same again.

In list.phtml <?php $_columnCount = $this->getColumnCount(); ?> I can update $_columnCount with 2 but again it will affect desktop devies.

I want to set 2 columns for mobile devices and 3 columns for desktop. How I can achieve it?

    Do you have responsive design or you have any different theme or store for mobile device ? – Akhilesh Patel Nov 9 '15 at 4:37

you can add mobile check by using this $_SERVER['HTTP_USER_AGENT']

if (preg_match("/Mobile|Android|BlackBerry|iPhone|Windows Phone/", $_SERVER['HTTP_USER_AGENT'])) {
      //use your condition here for column count

        }

In order to fulfill your requirement you need do track agent is Mobile browser.

And using Observer create a new layout handler.On this handler,you need to set root layout template 3-columns.phtml .

  • Use Zend libary function Zend_Http_UserAgent_Mobile::match($userAgent=Mage::helper('core/http')->getHttpUserAgent(), $server=$_SERVER); for track the current user agent coming from Mobile
  • use controller_action_layout_load_before for fire an observer which will create new handler whenever current user agent is coming from Mobile.
  • On that new handler you will set 3-columns.phtml as root template for coming Mobile

Handler Format: Mobile_PAGE

Observer code:

<?php
class [ModuleNameSpace]_[ModuleName]_Model_Observe{ 
/**
     * Before load layout event handler
     *
     * @param Varien_Event_Observer $observer
     */
    public function beforeLoadLayout($observer)
    {
        if($observer->getEvent()->getAction()->getFullActionName()=='catalog_category_view'){
        $IsCurrentDriveMob=Zend_Http_UserAgent_Mobile::match($userAgent=Mage::helper('core/http')->getHttpUserAgent(), $server=$_SERVER);
        if($IsCurrentDriveMob):
        $layout = $observer->getEvent()->getLayout();
                    $layout->getUpdate()->addHandle('Mobile_PAGE');
        // check all Handler 
        //Zend_Debug::dump($layout->getUpdate()->getHandles());
        endif;
        }
    return ;
    }


}

Config.xml code;

<global>
    <models>
        <[MyCustomModule_Model_Class_Groupname]>
            <class>[ModuleNameSpace]_[ModuleName]_Model</class>
        </[MyCustomModule_Model_Class_Groupname]>
    </models>
</global>
   <frontend>
        <events>
            <controller_action_layout_load_before>
                <observers>
                    <my_current_page_is_observer>
                        <class>[MyCustomModule_Model_Class_Groupname]/observer</class>
                        <method>beforeLoadLayout</method>
                    </my_current_page_is_observer>
                </observers>
            </controller_action_layout_load_before>
     </events>
   </frontend>

Now on this of this handler,you can add a new block to layout and a new phtml.

Now you can change template using Mobile_PAGE hanlder

<Mobile_PAGE>
<reference name="root">
    <action method="setTemplate"><template>page/3columns.phtml</template></action>
</reference
</Mobile_PAGE>

Also ,you can use controller_action_layout_generate_blocks_after event.Check this event use at Marius answer
