我们得到一对夫妇的Prestashop通告当客户将产品添加到购物车,即如下:未定义的常量在PHP
Impossible to add the product to the cart. textStatus: 'parsererror' errorThrown: 'SyntaxError: Unexpected token < in JSON at position 0' responseText:
Notice: Use of undefined constant id_customization_field_width - assumed 'id_customization_field_width' in /home/public_html/override/controllers/front/CartController.php on line 83
Notice: Use of undefined constant id_customization_field_height - assumed 'id_customization_field_height' in /home/public_html/override/controllers/front/CartController.php on line 83
代码(行83),此是指如下:
/*add new customization cart*/
$id_customization = 0;
if ($this->_newCustomization && id_customization_field_width && id_customization_field_height) {
if ($this->context->customer->isLogged()) {
$id_adv = $this->context->cart->id_address_delivery;
} else {
$id_adv = 0;
}
任何人都可以帮忙吗?我们似乎无法找到问题所在。
将'id_customization_field_height'更改为'$ id_customization_field_height' ...对'id_customization_field_width'做同样的处理 –
