Question

我创建了一个查询表单，允许用户提交查询，然后通过电子邮件发送确认。这工作正常，但验证的最后一部分似乎不起作用，因此当它不应该发送时发送电子邮件。

表单获取的数据是名称，电子邮件和安全问题，非常简单地输入介于1和1之间的数字。 9.不接受信件，因为表格已设置为＆＃34; number＆＃34;使用HTML，但它确实接受数字0＆amp;它似乎也接受超过9的任何数字。

我相当肯定我的IF声明不正确，但无法弄清楚出了什么问题。任何帮助将不胜感激。

代码

<?php
    require_once __DIR__ . ('/../config/init.php');

    //Checks if data has been posted off .. if so run validation
    if($_POST){

        if (!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)){
            $response = '<h5>Error</h5><p>Please Enter a valid email address</p>';
        }

        else if (empty($_POST['query'])){
            $response = "<h5>Error</h5><p>You have not entered a query. Please go back and try again";
        }

        else if (empty($_POST['check']) || $_POST['check']<1 && $_POST['check']>=9){
            $response = "<h5>Error</h5><p>Number entered not valid. Please go back and try again</p>";
        }

        else{
            $message = 'Thank you for enquiry. We will contact you as soon as possible';
            $headers = 'From: webmaster@jamesvause.co.uk' . "\r\n" .
                       'Reply-To: webmaster@jamesvause.co.uk' . "\r\n" .
                       'X-Mailer: PHP/' . phpversion();
            mail($_POST['email'], 'Your Enquiry', $message, $headers);

            $response = '<h3>Thank you for your enquiry</h3>';
        }

    }
