Suppose, we have a module demomodule<\/strong> that has a multi-lang field in the table and we want to update\/get the language-wise data with Prestashop’s post\/get API requests. For this, we use the concept of association<\/a>. <\/p>\n\n\n\n Override $webserviceParameters<\/strong> protected variable of core Prestashop file product.php by module and add association for demomodule<\/strong> in the demomodule\/override\/product.php<\/strong> like below code :<\/p>\n\n\n\n With the i18n<\/strong> parameter, it will create a language-wise node of data associated with the product and write the given code in the getter function of demomodule\/override\/product.php<\/p>\n\n\n\n The output will be like this on API call : <\/p>\n\n\n\n To update data, we need to override \/classes\/webservice\/WebserviceRequest.php<\/strong> class function saveEntityFromXml<\/strong> like the below code<\/p>\n\n\n\n In the above code, we have added the fav_country<\/strong> country condition to pass the language-wise data array to the setter function<\/p>\n\n\n\n Now, define the setter function in the demomodule\/override\/product.php file like this<\/p>\n\n\n\n Note:<\/strong> After the above process disable and enable the installed module (demomodule).<\/p>\n\n\n\n That\u2019s all about this blog.<\/p>\n\n\n\n If any issue or doubt please feel free to mention it in the comment section.<\/p>\n\n\n\n I would be happy to help.<\/p>\n\n\n\n Also, you can explore our PrestaShop Development Services<\/a> & a large range of quality PrestaShop Modules<\/a>.<\/p>\n\n\n\n For any doubt contact us at support@webkul.com<\/a><\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":"protected $webserviceParameters = [\n 'objectMethods' => [\n 'add' => 'addWs',\n 'update' => 'updateWs',\n ],\n 'objectNodeNames' => 'products',\n 'fields' => [\n 'id_manufacturer' => [\n 'xlink_resource' => 'manufacturers',\n ],\n 'id_supplier' => [\n 'xlink_resource' => 'suppliers',\n ],\n 'id_category_default' => [\n 'xlink_resource' => 'categories',\n ],\n 'new' => [],\n 'cache_default_attribute' => [],\n 'id_default_image' => [\n 'getter' => 'getCoverWs',\n 'setter' => 'setCoverWs',\n 'xlink_resource' => [\n 'resourceName' => 'images',\n 'subResourceName' => 'products',\n ],\n ],\n 'id_default_combination' => [\n 'getter' => 'getWsDefaultCombination',\n 'setter' => 'setWsDefaultCombination',\n 'xlink_resource' => [\n 'resourceName' => 'combinations',\n ],\n ],\n 'id_tax_rules_group' => [\n 'xlink_resource' => [\n 'resourceName' => 'tax_rule_groups',\n ],\n ],\n 'position_in_category' => [\n 'getter' => 'getWsPositionInCategory',\n 'setter' => 'setWsPositionInCategory',\n ],\n 'manufacturer_name' => [\n 'getter' => 'getWsManufacturerName',\n 'setter' => false,\n ],\n 'quantity' => [\n 'getter' => false,\n 'setter' => false,\n ],\n 'type' => [\n 'getter' => 'getWsType',\n 'setter' => 'setWsType',\n ],\n ],\n 'associations' => [\n 'categories' => [\n 'resource' => 'category',\n 'fields' => [\n 'id' => ['required' => true],\n ],\n ],\n 'images' => [\n 'resource' => 'image',\n 'fields' => ['id' => []],\n ],\n 'combinations' => [\n 'resource' => 'combination',\n 'fields' => [\n 'id' => ['required' => true],\n ],\n ],\n 'product_option_values' => [\n 'resource' => 'product_option_value',\n 'fields' => [\n 'id' => ['required' => true],\n ],\n ],\n 'product_features' => [\n 'resource' => 'product_feature',\n 'fields' => [\n 'id' => ['required' => true],\n 'id_feature_value' => [\n 'required' => true,\n 'xlink_resource' => 'product_feature_values',\n ],\n ],\n ],\n 'tags' => ['resource' => 'tag',\n 'fields' => [\n 'id' => ['required' => true],\n ], ],\n 'stock_availables' => ['resource' => 'stock_available',\n 'fields' => [\n 'id' => ['required' => true],\n 'id_product_attribute' => ['required' => true],\n ],\n 'setter' => false,\n ],\n 'attachments' => [\n 'resource' => 'attachment',\n 'api' => 'attachments',\n 'fields' => [\n 'id' => ['required' => true],\n ],\n ],\n 'accessories' => [\n 'resource' => 'product',\n 'api' => 'products',\n 'fields' => [\n 'id' => [\n 'required' => true,\n 'xlink_resource' => 'products', ],\n ],\n ],\n 'product_bundle' => [\n 'resource' => 'product',\n 'api' => 'products',\n 'fields' => [\n 'id' => ['required' => true],\n 'id_product_attribute' => [],\n 'quantity' => [],\n ],\n ],\n 'wk_fields' => [\n 'resource' => 'wk_field',\n 'api' => 'products',\n 'fields' => [\n 'fav_country' => ['required' => true, 'i18n' => true],\n ],\n 'setter' => 'setFavCountryFieldData',\n 'getter' => 'getFavCountryFieldData'\n ],\n ],\n];<\/pre>\n\n\n\n
