Multi Conditionals (OR and AND inside AND) in addAttributeToFilter

Question

How to create a multi-condition in addAttributeToFilter?

I want result in a SQL query like this (image attached) :

WHERE ((`e`.`news_from_date` > '2013-09-12') OR (`e`.`news_to_date` < '2013-09-12'))
AND ((((`e`.`special_price` IS NULL))) OR (((`e`.`special_price` IS NOT NULL)) AND ((`e`.`special_from_date` < '2013-09-12') OR (`e`.`special_to_date` > '2013-09-12'))))

$collection->addAttributeToFilter('special_price', array('null'=>'special_price'), 'left');

Thank you

You should be able to combine most of these techniques to create the query you want. For sales tables, you probably will use addFieldToFilter - but Zend_Db_Expr is likely the path of least resistance for you :

addAttributeToFilter :

According to the Magento Wiki : When creating parentheticals that have OR conditions you can do the following:

If an array is passed but no attribute code specified, it will be interpreted as a group of OR conditions that will be processed in the same way.

So, from that we can construct the following :

$collection->addAttributeToFilter(
    array(
        array('attribute'=> 'someattribute','like' => 'value'),
        array('attribute'=> 'otherattribute','like' => 'value'),
        array('attribute'=> 'anotherattribute','like' => 'value'),
    )
);

This will output a WHERE clause of the format :

WHERE ((someattribute LIKE 'value') OR (otherattribute LIKE 'value') OR (anotherattribute LIKE 'value'))

addFieldToFilter :

In the case where the model is directly linked to a DB table, the following is required for applying conditionals to the database column by name :

$collection->addFieldToFilter(
    array('title', 'content'),
    array(
        array('like'=>'%$titlesearchtext%'), 
        array('like'=>'%$contentsearchtext%')
    )
)

Zend_Db_Expr :

For much more complicated constructs you can build your own where clause using Zend_Db_Expr. For instance :

$collection->getSelect()->where(new Zend_Db_Expr("(e.created_at > '2013-01-01 00:00:00' OR e.created_at <'2012-01-01 00:00:00)"));

If you want to include AND with the combination of OR then

$colemanManufacturerSku = Mage::getResourceModel('catalog/product_collection')
    ->addAttributeToSelect('sku')
    ->addAttributeToSelect('sku_1')
    ->addAttributeToSelect('sku_2')
    ->addAttributeToSelect('sku_3')
    ->addAttributeToFilter('type_id', array('eq' => 'simple'))
    // Above condition will AND with following OR
    ->addAttributeToFilter(
        array(
            array(
                'attribute' => 'sku_1',
                'neq' => ''
            ),
            array(
                'attribute' => 'sku_2',
                'neq' => ''
            ),
            array(
                'attribute' => 'sku_3',
                'neq' => ''
            )
        )
    );

Or condition using addFieldToFilter

$collection->addFieldToFilter
                (   
                    array('email','mobile'),
                    array($emaiId,$mobNum)
                );
