Question

我有以下if语句正常工作：

if ($user['email_only'] === '1') {
    $newsubscriber['subscriberMessage'] = array('masterId' => '1090438');
} else if($user['email_only'] === '0') {
    $newsubscriber['subscriberMessage'] = array('masterId' => '1090442');
}

但是，我想在此周围添加一个额外的if语句，以便我可以根据用户所在国家/地区设置不同的ID，我想出了以下内容，但它不起作用？

if ($user['country'] === 'au') {
    if($user['email_only'] === '1') {
        $newsubscriber['subscriberMessage'] = array('masterId' => '1091479');
} else {
        $newsubscriber['subscriberMessage'] = array('masterId' => '1090589');
    }
} // AU country END 
else if ($user['country'] === 'de') {
    if($user['email_only'] === '1') {
        $newsubscriber['subscriberMessage'] = array('masterId' => '1090438');
    } else {
        $newsubscriber['subscriberMessage'] = array('masterId' => '1090442');
    }
} // DE country END

有人可以帮助我解决我的错误吗？

Answer 1

不要使用完全相等的（===），除非您需要并且绝对确定您获得的数据。试试这个：

if ($user['country'] == 'au') {
    if($user['email_only'] == '1') {
        $newsubscriber['subscriberMessage'] = array('masterId' => '1091479');
} else {
        $newsubscriber['subscriberMessage'] = array('masterId' => '1090589');
    }
} // AU country END 
else if ($user['country'] == 'de') {
    if($user['email_only'] == '1') {
        $newsubscriber['subscriberMessage'] = array('masterId' => '1090438');
    } else {
        $newsubscriber['subscriberMessage'] = array('masterId' => '1090442');
    }
} // DE country END

您可以做的另一件事是var_dump($user);，以确保您在country和email_only中具有您期望的预期值。

实际上，你应该正确地格式化代码......我也不会在这个混乱中找到错误。

if ($user['country'] === 'au'){
    if ($user['email_only'] === 1) {
        $newsubscriber['subscriberMessage'] = array('masterId' => '1090438');
    }else if($user['email_only'] === 0){
        $newsubscriber['subscriberMessage'] = array('masterId' => '1090442');
    }//AU END
} else if ($user['country'] === 'de'){
    if ($user['email_only'] === 1) {
        $newsubscriber['subscriberMessage'] = array('masterId' => '1090438');
    }else if($user['email_only'] === 0){
        $newsubscriber['subscriberMessage'] = array('masterId' => '1090442');
    }
} //DE END
