在WooCommerce中,我目前正在尝试在Checkout中添加一个条件自定义字段,该字段显示一个复选框,如果选中该复选框,则会显示一个输入字段以插入意大利语财务代码(Codice Fiscale)。
感谢各种指南和插件代码,我能够在结帐时显示它,但我在做错了代码并遇到了几个问题:
注意:意大利法律规定,如果私人客户要求开具发票,他必须同时插入(有效)“codice fiscale”(财务代码) )。
为避免并发症,我没有插入任何高级检查工具(这将需要更多字段,例如生日)。相反,我通过模式标记设置了这个简短的控件:
jQuery('#cf_in').prop('pattern', "^[a-zA-Z]{6}[0-9]{2}[a-zA-Z][0-9]{2}[a-zA-Z][0-9]{3}[a-zA-Z]$");
我在互联网上找到它,但不知道它是否可行。我也有这个:
function isCodiceFiscaleValid($valore,$codice_fiscale = true){
$espressione = "^[a-z]{6}[0-9]{2}[a-z][0-9]{2}[a-z][0-9]{3}[a-z]$";
if(!$codice_fiscale){
$espressione = "^[0-9]{11}$";
}
if ( eregi($espressione, $valore) )
{
return true;
}
return false;
}
检查后,一旦插入的“Codice fiscale”(财政代码)好,我们就可以继续结账,为客户显示并管理这个“codice fiscale”。
我还需要使用 WooCommerce PDF Invoices& amp;装箱单Pro 插件(商业版)。

如果你能在这里帮助我,我将非常感激。

在这个答案中我不能处理PDF发票,所以你会到这里:
另外我有:

代码放在活动子主题(或主题)的function.php文件中,或者放在任何插件文件中。
所有代码都在Woocommerce 3+上进行测试并且有效。
