How to remove the left sidebar based on some condition written in block? I have to use the same layout xml file. Based on a condition, need to remove a block through coding. section need to be removed:

 <reference name="left"> <block type="catalog/layer_view" name="catalog.leftnav" before="-" template="catalog/layer/view.phtml"/> </reference>

I tried with below code. 

Mage::app()->getLayout()->unsetBlock('left.catalog.leftnav');

I didn't get any error but left sidebar still there. can anyone help me? Thanks.

  1. I cant access controller. If i have access for controller, then i can easily do in layout rendering section. So i added my work as module and created block. Now I need to change layout / remove left sidebar.

  2. Or is It possible to change the layout xml from block? Because i have condition statement in block. so i can choose the layout based on the condition.

Can anyone help me to fix this? Thanks

If you do not want to use an observer what you could do is rewrite the block Mage_Catalog_Block_Layer_View and override the function _toHtml so that it performs the conditional check you want.

protected function _toHtml() { if (your conditional check) { return ''; } return parent::_toHtml(); }

you can try to listen some event like controller_action_layout_load_before and you will get layout object like

$update = $observer->getEvent()->getLayout()->getUpdate();

now you can remove/unset the block
