I want to have a default value in a column on sales grid, the value will be the actual day.
$this->addColumn('created_at', array( 'header' => Mage::helper('sales')->__('Purchased On'), 'index' => 'created_at', 'type' => 'datetime', 'width' => '100px', 'filter_index' => 'main_table.created_at', 'value'=>array( 'from'=>date('Y-m-d', time()) ) )); But its not working and I don't know why.
How can I do that?
try below code
$this->addColumn('created_at', array( 'header' => Mage::helper('sales')->__('Purchased On'), 'index' => 'created_at', 'type' => 'datetime', 'width' => '100px', 'filter_index' => 'main_table.created_at', 'value'=>array( 'from'=>date('Y-m-d') ) )); 
$this->setDefaultFilter( $arrayFilter ); In the _prepareColumns method of my custom class extending Mage_Adminhtml_Block_Catalog_Product_Grid I was able to set a filter like this:
$this->setDefaultFilter(array('status' => Mage_Catalog_Model_Product_Status::STATUS_ENABLED)); or
$this->setDefaultFilter(array('name' => 'foo')); File Path:
app/code/core/Mage/Adminhtml/Block/Sales/Order/Grid.php
Put your code these way You can See Only actual day
$this->addColumn('created_at', array( 'header' => Mage::helper('sales')->__('Purchased On'), 'index' => 'created_at', 'type' => 'date', 'width' => '100px', )); 
$this->setDefaultFilter( $arrayFilter );
