Product Export: Exporting a field from a external table

Prerequisites

The field has to be present in the database and in a Product class override

Target

We would like to export a field added to a table from another module.

Setup

To add the field to the list of available export fields, click on the in the 'Add a field' panel and enter the following information:

What is the field ID?: my_field (has to correspond exactly to the field name in Product Class)

Sc creates the field, you now need to populate the grid with:

ID: my_field
Name: my_field

From the Advanced Properties panel on the right handside:

- select the menu Export Process and enter:

if (in_array($switchObject, array('my_field'))) {
    $field = 0;
    $sql = "SELECT `".$switchObject."` 
            FROM " . _DB_PREFIX_ . "my_table 
            WHERE id_product=" . (int)$p->id;
    $res = Db::getInstance()->ExecuteS($sql);
    if (count($res)) {
        $field = (int)$res[0][$switchObject];
    }
}

You will need to adapt this code to your needs.

Exit the editing window.

The new field can now be included in your export mapping.
