WooCommerce条件自定义结帐字段

标签: php jquery wordpress woocommerce checkout

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:

  1. 默认情况下,我希望它是非必需字段,只有在必须检查时才需要它。
  2. 如果我尝试继续购物车插入有效或非抄本fiscale我得到此错误“SyntaxError:Unexpected token< in JSON in position 0”,其中我的主题通常显示结帐错误。
  3. 仅以意大利语(使用WPML)
  4. 显示所有这些内容
  5. 我无法知道更多错误,而我无法解决前两点。
  6. 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)

    这里的引用(遗憾的是只能发布2):

    此处代码(在我的主题functions.php文件中添加)

    add_filter( 'woocommerce_checkout_fields' , 'cbi_cf_chkbox' );

        if ( ICL_LANGUAGE_CODE=='it' )

    如果你能在这里帮助我,我将非常感激。

1 个答案:

答案 0 :(得分:1)

在这个答案中我不能处理PDF发票,所以你会到这里:

  • 解决条件“必需”字段(第1点)
  • 的问题
  • 解决错误(第2点)
  • 的问题
  • 仅显示意大利语(第3点)

另外我有:

  • 重新访问了所有代码并纠正了许多小错误。
  • 添加了显示和编辑后端用户个人资料自定义字段值“codice fiscale”的代码:

    enter image description here

以下是代码:

add_filter( 'woocommerce_checkout_fields' , 'cbi_cf_chkbox' );
function cbi_cf_chkbox ( $fields ) {
    if ( ICL_LANGUAGE_CODE !='it' ) return $fields; // Only for Italy

    $fields['billing']['checkbox_cf'] = array(
        'type'      => 'checkbox',
        'label'     => __('Voui la fattura? (solo per privati)', 'cbi-custom-parts'),
        'class'     => array('form-row-wide'),
        'clear'     => true
     );

    $fields['billing']['cf_in'] = array(
        'label'     => __('Inserisci il codice fiscale', 'cbi-custom-parts'),
        'placeholder'   => _x('RSSMRA85T10A562S', 'placeholder', 'cbi-custom-parts'),

            $('#cf_in_field').hide();

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。
