I am processing some records and I need to set a datetime field to the current time for multiple rows. I have all the row IDs. What's the best way to do this with Magento 1? The SQL would be like this:

    processed_on = "2015-09-09 11:11:04"
    id in(34, 56, 77, 39)

Instead of load/save inside foreach, you can try this:

$collection = Mage::getModel('your/model')->getCollection()

foreach ($collection as $item) {
    $item->setProcessedOn('2015-09-09 11:11:04');

To update existing rows in a model, you need to load each row first, call addData() with the new data, then save the row.

An example would look like this:

$rowIds = array(1,2,3)
foreach($rowIds as $rowId) {
    $data = array('processed_on' => "2015-09-09 11:11:04");

    $model = Mage::getModel('your_model')->load($rowId)->addData($data);   
    try {
        echo "Record updated";  
    } catch (Exception $e){  
        echo $e->getMessage();

  • You should remove setId($id) before calling save() since $id is not defined and the model has already an id, because it is an existent record. – HelgeB Mar 7 '19 at 3:19

    You should also vaiud load/delete/save methods inside loops. – sv3n Mar 7 '19 at 17:00
