Updating Custom Product Field

[wakabayashi]

I have problems with updating a Product (custom fields) in Prestashop.

 

I followed the tutorial: http://blog.belvg.com/how-to-create-a-custom-product-tab-in-prestashop.html

 

It works quite fine, when I save a product the normal way. But Prestashop 1.6 has an autosave function, when changing stock or prices. This makes my custom fields empty. By trial & error I found out, that my hookActionProductUpdate function causes the problem, but I dont know why:

 

public function hookActionProductUpdate($params) {

    $id_product = Tools::getValue('id_product');

    $sampleObj = Belvg_Sample::loadByIdProduct($id_product);

    $sampleObj->lagerplatz = Tools::getValue('lagerplatz');

    $sampleObj->artnrlfr = Tools::getValue('artnrlfr');

    $sampleObj->archiv = Tools::getValue('archiv');

    $sampleObj->bundle = Tools::getValue('bundle');

    $sampleObj->beschrieb = Tools::getValue('beschrieb');

    $sampleObj->oldartnr = Tools::getValue('oldartnr');



    $sampleObj->id_product = $id_product;



    if(!empty($sampleObj) && isset($sampleObj->id)){

        $sampleObj->update();

    } else {

        $sampleObj->add();

    }

} 

What is wrong with it?

 

Thanks in advance!

I usually add an hidden field in the form

<input type="hidden" name="CUSTOM_TAB_LOADED" value="1">

Then in the update function

if(!Tools::getValue('CUSTOM_TAB_LOADED'))

return;

this way you only save it if it was loaded.

 

Got this answer in stackoverflow. It's a nice trick!
