Dynamic variables

The dynamic variable is a user-defined php code that must return a string value. The PHP code is stored on your server in your Magento installation folder. The extension fetches it from the file.

To create a new dynamic variable, follow these steps:

1. Go to Catalog → Advanced Product Feeds → Dynamic Variables. Press the button Add Variable.

2. Fill in the following fields:

   • Name - name of the dynamic variable
   • Variable Code - code of the dynamic variable. You will see this code when you select this dynamic variable in the templates.

1. Create the PHP code for the Dynamic variable:

• Login to your server.
• Navigate to the var/mst_feed/ or app/code/Mirasvit/Feed/ folder
• Create a PHP file in one of these folders named exactly as the Variable Code you have entered previously.
  For example, if the Variable Code is GTIN_variable, you need to create a file var/mst_feed/GTIN_variable.php or app/code/Mirasvit/Feed/GTIN_variable.php
• Paste the PHP code for your variable in the file and save it.

1. Return to your Magento admin and reload the page or click Save button. The section Code will show the PHP code that was fetched for this varible from your server.

To see an example of the dynamic variable output you can use the field right to the Code section.
Enter product ID's separated by commas to see the data for several products.
