动态 Email Recipient based on ZIP Code Input for Contact Form 7

Question

我们有 4 个办公室，许多办公室分配了 ZIP 代码：

• 21079, 22085,.... = 汉堡
• 10115、10178、.... = 柏林
• 60306、60312、....=法兰克福
• .....,......,.... = 慕尼黑
• 其他一切=总公司

是否可以从表格中读出ZIP代码输入并动态发送邮件到指定办公室？

它必须是动态的，没有所有 ZIP 代码或城市的下拉列表（在前端）。

我试过了没有成功

// hook into wpcf7_before_send_mail
add_action( 'wpcf7_before_send_mail', 'cf7dynamicnotifications'); // Hooking into wpcf7_before_send_mail

function cf7dynamicnotifications($contact_form) // Create our function to be used in the above hook
{
   $submission = WPCF7_Submission::get_instance(); // Create instance of WPCF7_Submission class
   $posted_data = $submission->get_posted_data(); // Get all of the submitted form data


   if( $posted_data["plz"] == '21079' ) { 
      $recipient_email = 'office1@xyz.com';
   }
   elseif($posted_data["plz"] == '22085') { 
      $recipient_email = 'office2@xyz.com';
   }
   elseif($posted_data["plz"] == '12345') { 
      $recipient_email = 'office3@xyz.com';
   }
   else { 
      $recipient_email = 'head-office@xyz.com';
   }
   // set the email address to recipient
   $mailProp = $contact_form->get_properties('mail');
   $mailProp['mail']['recipient'] = $recipient_email;

   // update the form properties
   $contact_form->set_properties(array('mail' => $mailProp['mail']));
}

谢谢您的帮助。 我的解决方案运行良好，但我的 email 提供商出现问题。

你知道我如何扩展价值吗？ 我想插入多个值。

例如：

if ( '21079', '21080', '21081' === $posted_data['plz'] ) { $recipient_email = 'office1@xyz.com';

这给了我一个语法错误。

这也没有用：

if ( '21079' || '21080' || '21081' === $posted_data['plz'] ) { $recipient_email = 'office1@xyz.com';

你的问题几乎是正确的。 set_properties()需要传递整个数组（在您的情况下） $mailProp 。

/**
 * Dynamically Change the recipient.
 *
 * @param object $contact_form The contact form 7 contact form object.
 * @return void
 */
function cf7dynamicnotifications( $contact_form ) {
    $submission  = WPCF7_Submission::get_instance(); // Create instance of WPCF7_Submission class.
    $posted_data = $submission->get_posted_data(); // Get all of the submitted form data.
    // Make sure the field is filled in.
    if ( isset( $posted_data['plz'] ) ) {
        if ( '21079' === $posted_data['plz'] ) {
            $recipient_email = 'office1@xyz.com';
        } elseif ( '22085' === $posted_data['plz'] ) {
            $recipient_email = 'office2@xyz.com';
        } elseif ( '12345' === $posted_data['plz'] ) {
            $recipient_email = 'office3@xyz.com';
        } else {
            $recipient_email = 'head-office@xyz.com';
        }
        // set the email address to recipient.
        $mailProp = $contact_form->get_properties( 'mail' );
        $mailProp['mail']['recipient'] = $recipient_email;
        // update the form properties.
        $contact_form->set_properties( array( 'mail' => $mailProp ) ); // Pass the whole array.
    }
}
