How to show Invoice Creation Date on Magento

Question

Now on magento when I print an Invoice as PDF, it shows "Order date".. we need to replace it with the "Invoice Creation Date".

Can you tell me how to do that?

Thanks.

Answer 1

Load the invoice by

$invoice = Mage::getModel('sales/order_invoice')->loadByIncrementId($invoiceIncrementId);

and then get the invoice date using

$createdDate = $invoice->getCreatedAt();

and put $createdDate and modify the below code from

$page->drawText(
            Mage::helper('sales')->__('Order Date: ') . Mage::helper('core')->formatDate(
                $order->getCreatedAtStoreDate(), 'medium', false
            ),
            35,
            ($top -= 15),
            'UTF-8'
        );

To

$page->drawText(
            Mage::helper('sales')->__('Invoice Creation Date: ') . Mage::helper('core')->formatDate(
                $createdDate, 'medium', false
            ),
            35,
            ($top -= 15),
            'UTF-8'
        );

NOTE :-

If you have multiple invoices for the same order then you can get the all invoice increment id by

$_invoices = $_order->getInvoiceCollection();
foreach($_invoices as $_invoice){

     $_invoice->getIncrementId() = $_invoice->getIncrementId();
}

Since Magento is creating PDF of orders strictly via PHP code (means it doesn't use any html->pdf parser or any similar idea), you will have to extend the class that does that and modify it accordingly. So, the class that you are looking for is:

Mage_Sales_Model_Order_Pdf_Invoice

with the method

protected function insertOrder(&$page, $obj, $putOrderId = true)

then search for

$page->drawText( Mage::helper('sales')->__('Order Date: ') . Mage::helper('core')->formatDate($order->getCreatedAtStoreDate(), 'medium', false), 35, ($top -= 15), 'UTF-8');

And I would guess that you know how to extend it with your own module. If not, the process is described in How to create a simple 'Hello World' module in Magento?.

I had same problem and added invoice date to app/code/core/Mage/Sales/Model/Order/invoice.php at line 132

 /* Add document text and number */
        $this->insertDocumentNumber(
            $page,
            Mage::helper('sales')->__('Invoice # ') . $invoice->getIncrementId()
 .' '.
        Mage::helper('sales')->__('Invoice date: ') . Mage::helper('core')->formatDate(
            $invoice->getCreatedAt(), 'medium', false
        ),
        35,
        ($top -= 15),
        'UTF-8'
        );
