Specific Prices (window): Adding a field from a table outside the specific prices table


  • Store Commander version 2014-03-12
  • SC Grids Editor Pro Add-on - version 1.0
  • The field needs to exist in your database



We would like to add the field "My field" which is located in the table ps_ma_table (this table does not exist in PrestaShop by default).

We will then be able to:

  • use filters to optimize the selection of specific prices
  • mass-edit this field using Store Commander's copy/paste option
  • rapidly export the specific prices panel with this field



  • To add the field to the list of available fields for your products grids, click on the add.png in the 'Add a field' panel and enter the following information:

What is the field ID? : my_field (should be exactly the name as it is in the database).

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

Field name: My field

Table: special

Type: multiple choice (should corresponds to the type of your field, here with preset values)


  • In this example, the fields are in table ps_my_table:


id_of_my_table, id_product, my_field


  • From the Advanced Properties panel:

List of choices (only if the field type is 'multiple choices, otherwise leave blank)

return array(0=>_l('None'), 1=>_l('Value 1'), 2=>_l('Value 2'));


SQLSelectDataSelect :

return ' ,mt.my_field';


SQLSelectDataLeftJoin : 

return " LEFT JOIN "._DB_PREFIX_."my_table  mt  ON (mt.id_product= p.id_product)";


onAfterUpdateSQL : 

if (isset($_POST["my_field"])) {
    $sql = "SELECT * FROM " . _DB_PREFIX_ . "ma_table WHERE id_product=" . (int)$id_product;
    $res = Db::getInstance()->ExecuteS($sql);
    $my_field = (int)Tools::getValue('my_field', 0);
    if (count($res)) {

        if ($my_field) {
            $sql = "UPDATE " . _DB_PREFIX_ . "my_table  SET my_field=" . (int)$my_field . "  WHERE id_product=" . (int)$id_product;
        } else {
            $sql = "DELETE FROM " . _DB_PREFIX_ . "my_table  WHERE id_product=" . (int)$id_product;
    } else {
        $sql = "INSERT INTO " . _DB_PREFIX_ . "my_table  (id_product,my_field) VALUES (" . (int)$id_product . "," . pSQL($my_field) . ")";


You will need to adapt this code to your needs.


  • Exit the editing window and add the field to your grids.
