Frequently Asked Questions

Can I get a license for my development/staging domain?

These licenses are included in every production domain license. Please send us after your purchase for your production domain an email with your order number and the desired development domain. We're happy to extend your license then.

DHL Location Finder Extension: Post number is printed multiple times in address

If you are using our Advanced Invoice Layout Extension with the DHL Extension Dhl_LocationFinder it may happen that if you have added the post number in the shipping address with the variable 

{{var dhl_post_number}}
you will see the following output on the PDF invoice or shipment document:
Postnumber: Postnumber: Postnumber: Postnumber: Postnumber: Postnumber: Postnumber: Postnumber: 32403197

This issue happens due to a small bug in the DHL Extension that listens to the Magento event customer_address_format and adds the "Postnumber: " prefix. But as this event can occur multiple times (as it will within the Advanced Invoice Layout extension) the prefix is also added multiple times.

As this is not the desired behaviour you can patch the method Dhl_LocationFinder_Model_Observer::addPostNumberLabel() to only add the prefix once:

public function addPostNumberLabel(Varien_Event_Observer $observer)
    {
        $address = $observer->getData('address');
        $postNumberLabel = Mage::helper('dhl_locationfinder/data')->__('Postnumber: ');
        if ($address->getData('dhl_post_number') && strpos($address->getData('dhl_post_number'), $postNumberLabel) === false) {
            $postNumberString = $postNumberLabel . $address->getData('dhl_post_number');
            $address->setData('dhl_post_number', $postNumberString);
        }
    }

Please note that this was tested with Dhl_LocationFinder extension version 1.0.3.

Error message "Mage registry key already exists" after extension installation
After installing a Magento extension you get the following error message, e.g. if you try to login the Magento admin backend:
Mage registry key <...> already exists


Solution:
Please confirm that you followed all installation steps that are mentioned in the Readme file of the module. Especially assure that the Magento cache is cleared, e.g. by emptying the var/cache/ directory in a Magento default installation and that the Magento compilation process has been triggered (if enabled).
How can I activate the PDF email attachment feature with other email extensions like Ebizmarts_Mandrill?

Important note

This issue is resolved in AdvancedInvoiceLayout Version 2.2.0. Please contact us to check if you can upgrade.

Short explanation

To realize the email attachment functionality in our AdvancedInvoiceLayout extension we had to extend the Magento core email logic to add methods for attaching documents. Unfortunately there is no way to do this without conflicts with other extensions that do the same, e.g. Ebizmarts_Mandrill or Aschroder_SMTPPro.

Solution

To solve this problem the following manual steps are required:

  • Make the AdvancedInvoiceLayout extension dependant on the other extension by creating a new file app/etc/modules/ZVianetz_AdvancedInvoiceLayout_Compatibility.xml with the following content (replace OtherVendor_OtherExtension with the extension name)
  • Copy the file app/code/community/Vianetz/AdvancedInvoiceLayout/Model/Email/Template to app/code/local/Vianetz/AdvancedInvoiceLayout/Model/Email/Template and replace the beginning with 
    Vianetz_AdvancedInvoiceLayout_Model_Email_Template extends Ebizmarts_Mandrill_Model_Email_Template
  • Flush the Magento Cache

How can I change the font family in the Magento PDF invoice?

With our AdvancedInvoiceLayout extension it is easy to change the font family in the Magento PDF invoice.
Therefore the AdvancedInvoiceLayout extensions ships with several default fonts which you can choose from:
Courier, DejaVu Sans, Helvetica, Times

Due to licensing issues it is not possible to add other font families by default but you can also easily add your own font family with the following steps:

If you want to use Internet Fonts, e.g. Google Fonts

(Note: this supported by our Advanced Invoice Layout Extension for Magento 1 from version 2.3.16 or newer or for Magento 2)
Additional fonts can easily be embedded via CSS, e.g. with Google Fonts: 
@font-face {
  font-family: 'Roboto';
  font-weight: bold;
  src: url('https://fonts.googleapis.com/css?family=Roboto'); 
}

If you want to use local fonts, e.g. in TTF format

Advanced Invoice Layout for Magento 1 with version 2.3.16 or newer

You have to download the load_font.php utility from GitHub to the folder lib/dompdf-advancedinvoicelayout/ and change the third line of the file to 

require_once "autoload.inc.php";
Then change into the directory lib/dompdf-advancedinvoicelayout.

Advanced Invoice Layout for Magento 2

You simply have to download the load_font.php utility from GitHub to the Magento root folder.

  • Then you need to make sure that the used DomPDF library gets to know the new font by executing the following command in the Magento root directory (replace MyFont with your desired font):
    php -f load_font.php 'MyFont' /path/to/myfont
  • Finally you can use the font in your CSS with 
    font-family: MyFont;

Advanced Invoice Layout for Magento 1 with version 2.3.15 or older
  • You need to temporarily rename the file lib/dompdf/dompdf_config.custom.inc.php to something else.
  • Then change into the directory lib/dompdf-advancedinvoicelayout.
  • Execute the above mentioned load_font.php command.
  • Afterwards inject the new font into the XML config object (see app/code/community/Vianetz/AdvancedInvoiceLayout/etc/config.xml) by extending the XML node default/advancedinvoicelayout/fonts, e.g.
    <verdana title="Verdana"/>
    The node title must match the generated file in step 2.

And that's it. Now you can choose the new font family in the configuration section under System > Configuration > AdvancedInvoiceLayout.


For further explanations see also the PDF Library documentation about About Fonts and Character Encoding.

How can I create different PDF invoice layouts for different Magento store views?

With our Advanced Invoice Layout Extension for Magento you can easily create store view specific layouts, texts, logos or colors. Therefore you can easily change the store view switcher on the Advanced Invoice Layout configuration page in the Magento backend.

If you want further more layout customizations to the HTML files there are 2 possibilities:

  • If you use already different Magento themes you can easily do the customizations in the appropriate theme folder (please also see our FAQ entry How to change the Magento PDF invoice layout?). I.e. you just do the customizations e.g. in app/design/frontend/theme1/default/advancedinvoicelayout and app/design/frontend/theme2/default/advancedinvoicelayout.
  • Additionally there is the possibility (e.g. if you use the same theme for both store views) to create own themes in the Advanced Invoice Layout extension.
How can I customize the Magento 1 PDF invoice layout?

With our Magento Extension Advanced Invoice Layout it is very easy to create individual layouts for Magento PDF invoices, shipments and creditmemos.

Want to see some examples? Check out some sample invoice layouts from our customers.

The extension ships with a base HTML layout that already fits for many cases. Furthermore we will release more enhanced step by step so that you can customize the PDF layout without any effort.

Your own customizations can be done with HTML/CSS. The appropriate files are in the following directories
  • app/design/frontend/base/default/template/advancedinvoicelayout/default
  • skin/frontend/base/default/advancedinvoicelayout/default/css

We recommend to do your own customizations within these files in your custom theme folder to avoid loosing changes in case that the Extension got an upgrade.
I.e. assuming that your Magento theme is in folder app/design/frontend/MYTHEME/default/ and you want to customize the invoice layout we recommend to copy the file app/design/frontend/base/default/template/advancedinvoicelayout/invoice.phtml to app/design/frontend/MYTHEME/template/default/advancedinvoicelayout/invoice.phtml.

For more experienced users we also deliver SASS files that allows an easier modification of e.g. colors in the whole document.

Please see also how to customize the payment block in the Magento PDF invoice.

Basically it is always recommended to activate the Debug Mode of the AdvancedInvoiceLayout extension for testing different layouts under System > Configuration > AdvancedInvoiceLayout. With activated Debug Mode the intermediate HTML file will be saved with each print of the PDF invoice, shipment or creditmemo into the directory var/tmp/invoice_debug.html. Therewith you can analyze and customize the HTML structure and CSS style sheets more easily.
However you are advised to disable this setting in production environments for performance reasons.

Please see also the available variables.

How can I customize the payment block in the Magento PDF invoice?
The AdvancedInvoiceLayout Extension prints a block with information about the chosen payment method onto the PDF invoice. This block is dynamically filled by the used Magento Payment Extension, e.g. PayPal, DebitPayment, Credit Card, etc. and so this is information is contained in the appropriate Extension files. For example for PayPal the payer email address is printed, for credit cards the credit card number and so on.

So if we want to customize e.g. the text/formatting that is printed on the invoice in case of "Purchase Order" payments we have to do the following steps:
  • copy file app/design/frontend/base/default/template/payment/info/purchaseorder.phtml to your theme folder i.e. app/design/frontend//default/template/payment/purchaseorder.phtml
  • customize the file to your needs

Basically it is always recommended to activate the Debug Mode of the AdvancedInvoiceLayout extension for testing different layouts under System > Configuration > AdvancedInvoiceLayout. With activated Debug Mode the intermediate HTML file will be saved with each print of the PDF invoice, shipment or creditmemo into the directory var/tmp/invoice_debug.html. Therewith you can analyze and customize the HTML structure and CSS style sheets more easily.
However you are advised to disable this setting in production environments for performance reasons.

This process can be done analoguous for other payment methods as well.

All you have to do is go to System > Configuration > Customer Configuration > Address Templates and in the field Advanced Invoice Layout PDFs add the following variable:

How can I run the unit tests for your extension?
The unit tests of our extensions are based on the EcomDev_PHPUnit module that can be found on Github.
For installation instructions please see the appropriate manual.

After installation of the EcomDev_PHPUnit extension you can run e.g. the AdvancedInvoiceLayout tests by the following command in the root folder of your Magento installation: 
phpunit --group Vianetz_AdvancedInvoiceLayout


If everything is fine you should get a green output that says that all tests ran successfully.
How can I send Magento invoice/shipment emails to store owner only?
With our AutomaticInvoice extension you can send invoice emails to store owner exclusively (i.e. not to the customer). Therefore you have to set the following configurations:
  • System > Configuration > AutomaticInvoice > Invoice > Notify Customer: No
  • System > Configuration > Sales Emails > Invoice > Send Order Copy Method: Separate Email


The same applies to shipment emails as well:
  • System > Configuration > AutomaticInvoice > Shipment > Notify Customer: No
  • System> Configuration > Sales Emails > Shipment > Send Order Copy Method: Separate Email
How can I show additional text in tax-free PDF invoices in Magento?

Our Advanced Invoice Layout Extension for Magento allows you to have customer group specific texts on the PDF invoice document.
Therefore on the customer group configuration page in the Magento admin panel there is an additional text field where you can enter HTML-text that will be displayed on PDF invoices if the customer is contained in that customer group.

The automatic group assignment is a standard Magento feature which is explained in more detail in the Magento Documentation.
How can I show custom attributes on the Magento invoice?
With our Advanced Invoice Layout Extension for Magento 1 it is very easy to display custom product attributes on the Magento PDF invoice, shipment or creditmemo.

If you want to display custom product attributes with our Advanced Invoice Layout Extension for Magento 2 you can add custom attributes to the PDF invoice by adding the following code to the theme template file default/item/invoice.phtml: 

echo $this->getProduct()->getData('your_attribute_code');

The sample applies also for the shipment and creditmemo PDF documents.

How to translate the Magento PDF invoice?

With our AdvancedInvoiceLayout extension you are able to customize the Magento default PDF invoice layout to adapt it to your needs and improve the look'n'feel of the invoice.
Therefore you can also easily add your own translations (of course this in accordance to Magento best practices):

  • Identify the text string that you want to translate in the template files in app/design/frontend/base/default/template/advancedinvoicelayout, e.g. the string "Invoice #%s" in app/design/frontend/base/default/template/advancedinvoicelayout/default/invoice.phtml
  • Search for this text string in file app/locale/xx_XX/Vianetz_AdvancedInvoiceLayout.csv with xx_XX being the locale code, e.g. "de_DE".
  • If the text string is available just change the translation to your needs, otherwise add a new line at the end of the file with your translation like 
    "Invoice #%s","Ihre Rechnung Nr. %s"
  • Flush the Magento Cache in the backend
I get a "404"-Error after the installation of the extension
Symptom: A 404 error is shown if you go to System->Configuration and choose e.g. AdvancedInvoiceLayout tab.

To solve this kind of error you need to log out of the backend and log in again. Then the tab should be successfully accessible.
I get the error message "There has been an error processing your request". What can I do?
Please take a look at the var/report directory and look for a file with the number mentioned in the error report. This file contains additional information about the problem. If you do not have a solution for this please send us the contents of the file to support@vianetz.com.
Magento shows a Blank Page
While executing some actions Magento is only showing a blank page without any content.
This behaviour is mostly caused by a Fatal PHP error. Please have a look into your PHP log files (perhaps ask your hoster) and/or see the Magento error log in the directory var/log of your Magento installation.
What can I do if Magento invoice emails are not sent anymore?
If you use our AutomaticInvoice Extension and invoice emails are not sent anymore please check the following points:
  • Please check the configuration at System > Configuration > Automatic Invoice:
    Is the Automatic Invoice Extension activated and are the checkboxes for "Generate Invoice" and "Notify Customer" triggered for the specific payment method?
  • Has the Magento invoice document been generated for the specific order and is it flagged as "invoice email sent"?
  • Which Magento Extension is used for the payment method? Perhaps it uses itself a mechanism for generating invoice document and sending the invoice email. Then perhaps it is better to exclude it from the Automatic Invoice generation.
  • Are there any error messages in the Magento and/or Automatic Invoice log files in var/log/?
Which data should I submit for a support request to vianetz?
