Products Grid: Adding a column displaying a product preset feature (editable)

Target

We would like to add a column displaying values of a specific feature in the products grid.

We will then be able to:

- rapidly export the products grid with this field
- edit quickly the feature on several products

Setup

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

What is the field ID?: myfeature

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

Field name: Delivery
Table: Another table
Type: multiple choice
Refresh combinations: No

From the Advanced Properties panel on the right handside:

- select the menu SQLSelect and enter:

return ' , (SELECT fp.id_feature_value FROM `' . _DB_PREFIX_ . 'feature_product` fp
                WHERE fp.id_feature = "3"
                AND fp.id_product = p.id_product) as myfeature ';

- select the menu Select options and enter:

$sql = "SELECT fvl.*
        FROM " . _DB_PREFIX_ . "feature_value_lang fvl
        INNER JOIN " . _DB_PREFIX_ . "feature_value fv ON (fv.id_feature_value=fvl.id_feature_value)
        WHERE fvl.id_lang=1
        AND fv.id_feature = 3";
$res = Db::getInstance()->ExecuteS($sql);
$tmp = array(0=>" ");
foreach ($res as $row)  {
    $tmp[$row["id_feature_value"]] = $row["value"];
}
return $tmp;

- select the menu PHP onAfterUpdateSQL and enter:

if ($feature_value = (int)Tools::getValue('myfeature', 0)) {
    $sql = "SELECT * FROM " . _DB_PREFIX_ . "feature_product WHERE id_product='" . (int)$idproduct . "' AND id_feature='3'";
    $res = Db::getInstance()->ExecuteS($sql);
    if (count($res)) {
        if ($feature_value) {
            $sql = "UPDATE " . _DB_PREFIX_ . "feature_product SET id_feature_value='" . (int)$feature_value . "' WHERE id_product='" . (int)$idproduct . "' AND id_feature='3'";
            Db::getInstance()->Execute($sql);
        } else {
            $sql = "DELETE FROM " . _DB_PREFIX_ . "feature_product WHERE id_product='" . (int)$idproduct . "' AND id_feature='3'";
            Db::getInstance()->Execute($sql);
        }
    } else {
        $sql = "INSERT INTO " . _DB_PREFIX_ . "feature_product (id_feature,id_product,id_feature_value) VALUES ('3','" . (int)$idproduct . "','" . (int)$feature_value . "')";
        Db::getInstance()->Execute($sql);
    }
}

In this instance, we use feature ID3. You can change the feature by looking for its ID in the Features panel (SC Catalog>Features)

Exit the editing window.

The new field is now present in the list of available fields and you can add it to your product grids.
