如何插入正则表达式以仅允许名称字段上的字母和空格并禁止＆＃34; - ＆＃34;仅在电话字段中输入短划线？这是代码。我相信我必须插入一个elseif条件，但我很难构建整个事情。

// loop through each of our form fields
    foreach ($fdata as $field => $value) {


        // Now switch functionality based on field name
        switch ($field) {

            // name
            case 'name':
                if (empty($value)) {
                    array_push($errors, parseMessage($translations->form->error->required->$lang, array($field)));
                }
                break;

            // email
            case 'email':
                if (empty($value)) {
                    array_push($errors, parseMessage($translations->form->error->required->$lang, array($field)));
                } elseif (!filter_var($value, FILTER_VALIDATE_EMAIL)) {
                    array_push($errors, $translations->form->error->email->$lang);
                }
                break;

            // phone number
            case 'phone':
                if (!empty($value) && !is_numeric($value)) {
                    array_push($errors, parseMessage($translations->form->error->numeric->$lang, array($field)));
                }
                break;

            // message
            case 'honey':
                if (!empty($value)) {
                    array_push($errors, $translations->form->error->honeypot->$lang);
                }
                break;

        }
    }

除非我误解了这个问题，否则这就是你所需要的：

switch ($field) {
    case 'name':
       # Check if the name is empty.
       if (empty($value)) {...}

       # If not, check if the name consists of letters and spaces.
       else if (preg_match("/^[a-z ]+$/i")) {...}

       break;

    case 'phone':
       # Check if the phone is empty.
       if (empty($value)) {...}

       # If not, check if the phone does not contain a hyphen.
       else if (preg_match("/^[^-]+$/")) {...}

       break;
}

添加正则表达式只允许字母，不允许某些字符
