如何解决Prestashop - 在产品组合上添加其他字段
我正在尝试在我的产品组合中添加其他字段，以便为组合提供自定义元标题。 所以我创建了这个模块：
我的模块定义：
class CombinationCustomFields extends Module
{
public function __construct()
{
$this->name = 'combinationcustomfields';
$this->tab = 'administration';
$this->author = '';
$this->version = '1.0';
$this->need_instance = 0;
$this->bootstrap = true;
parent::__construct();
$this->displayName = $this->l('Combination Custom Fields');
$this->description = $this->l('Add additional fields on combinations');
$this->ps_versions_compliancy = array('min' => '1.7.1','max' => _PS_VERSION_);
}
public function install()
{
if (!parent::install() || !$this->_installsql()
|| !$this->registerHook('displayAdminProductsCombinationBottom')
|| !$this->registerHook('actionAttributeCombinationSave')
) {
return false;
}
return true;
}
public function uninstall()
{
return parent::uninstall() && $this->_unInstallsql();
}
/**
* Add database fields
* @return boolean
*/
protected function _installsql()
{
$sqlInstall = "ALTER TABLE " . _DB_PREFIX_ . "product_attribute "
. "ADD Meta_title_fr VARCHAR(255) NULL,"
. "ADD Meta_title_en VARCHAR(255) NULL;";
$returnsql = Db::getInstance()->execute($sqlInstall);
return $returnsql;
}
/**
* Remove database fields
* @return boolean
*/
protected function _unInstallsql()
{
$sqlInstall = "ALTER TABLE " . _DB_PREFIX_ . "product_attribute "
. "DROP Meta_title_fr,"
. "DROP Meta_title_en";
$returnsql = Db::getInstance()->execute($sqlInstall);
return $returnsql;
}
public function hookdisplayAdminProductsCombinationBottom($params)
{
$combination = new Combination($params['id_product_attribute']);
$this->context->smarty->assign(array(
'id_product_attribute' => $params['id_product_attribute'],'Meta_title_fr' => $combination->Meta_title_fr,'Meta_title_en' => $combination->Meta_title_en,)
);
return $this->display(__FILE__,'views/templates/hook/combinationfields.tpl');
}
public function hookActionAttributeCombinationSave($params)
{
$combination = new Combination($params['id_product_attribute']);
$this->context->smarty->assign(array(
'id_product_attribute' => $params['id_product_attribute'],)
);
$combination->Meta_title_fr = Tools::getValue('Meta_title_fr');
$combination->Meta_title_en = Tools::getValue('Meta_title_en');
$combination->save();
return $this->display(__FILE__,'views/templates/hook/combinationfields.tpl');
}
}
我的管理挂钩 HTML：
<div class="m-b-1 m-t-1">
<h2>{l s='Combination Custom Fields' mod='combinationcustomfields'}</h2>
<fieldset class="form-group">
<div class="col-lg-12 col-xl-4">
<label class="form-control-label" for="combination_{$id_product_attribute}_attribute_Meta_title_fr">{l s='Meta title FR' mod='combinationcustomfields'}</label>
<input class="form-control" name="combination_{$id_product_attribute}[attribute_Meta_title_fr]" id="combination_{$id_product_attribute}_attribute_Meta_title_fr" type="text" value="{if $Meta_title_fr != ''}{$Meta_title_fr}{/if}">
<br />
</div>
<div class="col-lg-12 col-xl-4">
<label class="form-control-label" for="combination_{$id_product_attribute}_attribute_Meta_title_en">{l s='Meta title EN' mod='cmp_combination_customfields'}</label>
<input class="form-control" name="combination_{$id_product_attribute}[attribute_Meta_title_en]" id="combination_{$id_product_attribute}_attribute_Meta_title_en" type="text" value="{if $Meta_title_en != ''}{$Meta_title_en}{/if}">
<br />
</div>
</fieldset>
<div class="clearfix"></div>
</div>
我对组合类的覆盖：
class Combination extends CombinationCore
{
public $Meta_title_fr;
public $Meta_title_en;
/**
* @see ObjectModel::$deFinition
*/
public static $deFinition = [
'table' => 'product_attribute','primary' => 'id_product_attribute','fields' => [
'id_product' => ['type' => self::TYPE_INT,'shop' => 'both','validate' => 'isUnsignedId','required' => true],'location' => ['type' => self::TYPE_STRING,'validate' => 'isGenericName','size' => 64],'ean13' => ['type' => self::TYPE_STRING,'validate' => 'isEan13','size' => 13],'isbn' => ['type' => self::TYPE_STRING,'validate' => 'isIsbn','size' => 32],'upc' => ['type' => self::TYPE_STRING,'validate' => 'isUpc','size' => 12],'mpn' => ['type' => self::TYPE_STRING,'validate' => 'isMpn','size' => 40],'quantity' => ['type' => self::TYPE_INT,'validate' => 'isInt','size' => 10],'reference' => ['type' => self::TYPE_STRING,'supplier_reference' => ['type' => self::TYPE_STRING,'Meta_title_fr' => ['type' => self::TYPE_STRING,'Meta_title_en' => ['type' => self::TYPE_STRING,/* Shop fields */
'wholesale_price' => ['type' => self::TYPE_FLOAT,'shop' => true,'validate' => 'isPrice','size' => 27],'price' => ['type' => self::TYPE_FLOAT,'validate' => 'isNegativePrice','size' => 20],'ecotax' => ['type' => self::TYPE_FLOAT,'weight' => ['type' => self::TYPE_FLOAT,'validate' => 'isFloat'],'unit_price_impact' => ['type' => self::TYPE_FLOAT,'minimal_quantity' => ['type' => self::TYPE_INT,'low_stock_threshold' => ['type' => self::TYPE_INT,'allow_null' => true,'validate' => 'isInt'],'low_stock_alert' => ['type' => self::TYPE_BOOL,'validate' => 'isBool'],'default_on' => ['type' => self::TYPE_BOOL,'available_date' => ['type' => self::TYPE_DATE,'validate' => 'isDateFormat'],],];
}
但是当我保存产品时，字段在请求中：
知道我的错误吗？
祝您一切顺利，提前感谢您的帮助:)
解决方法
您可以使用覆盖控制器覆盖组合类：
class Combination extends CombinationCore
{
public $newVariableName;
public function __construct($id = null,$id_lang = null,$id_shop = null)
{
Combination::$definition['fields']['newVariableName'] = array('type' => self::TYPE_STRING,'validate' => 'isAnything','required' => false);
parent::__construct($id,$id_lang,$id_shop);
}
}
您还需要覆盖 product.php
public function updateProductAttribute($id_product_attribute,...,$newVariableName = null){
public function addCombinationEntity($wholesale_price,$newVariableName = null){
等等...
