Question

现在我正试图找出代码发生了什么。没有理由为什么它不起作用。当我提交表单时，我收到错误消息“评论二”，所以我知道问题出在哪里，但不明白为什么会发生这种情况。我创建的$ newfield变量似乎没有存储任何内容。有什么帮助吗？

HTML CODE：

<div id="contact-formular">

            <div id="message"></div>

            <form method="post" action="contact.php" name="contactform" id="contactform">

            <div class="one_half element_from_left" style="opacity: 1; left: 0px;">            
                <input name="name" type="text" id="name" size="30" onfocus="if(this.value == 'Name') { this.value = ''; }" onblur="if(this.value == '') { this.value = 'Name'; }" value="Name">
                <input name="email" type="text" id="email" size="30" onfocus="if(this.value == 'email') { this.value = ''; }" onblur="if(this.value == '') { this.value = 'email'; }" value="email">                
                <input name="phone" type="text" id="phone" size="30" onfocus="if(this.value == 'phone') { this.value = ''; }" onblur="if(this.value == '') { this.value = 'phone'; }" value="phone">            
            </div>

            <div class="one_half last element_from_right" style="opacity: 1; right: 0px;">      

                <textarea id="comments" type="text" class="top-text" name="comments" onfocus="if(this.value==this.defaultValue)this.value='';" onblur="if(this.value=='')this.value=this.defaultValue;" value="comments">Architect/ lighting designer/ property developer/ lighting enthusiast/ Will tell later</textarea>

                <textarea id="newfield" type="text" class="bottom-text" name="newfield"  onfocus="if(this.value==this.defaultValue)this.value='';" onblur="if(this.value=='')this.value=this.defaultValue;" value="newfield">Newfield</textarea>             

            </div>            

                <input type="submit" class="send_message" id="submit" value="SEND MESSAGE">

            </form>

        </div>

PHP代码：

if (!defined("PHP_EOL")) define("PHP_EOL", "\r\n");

$name     = $_POST['name'];
$email    = $_POST['email'];
$phone   = $_POST['phone'];
$newfield = $_POST['newfield'];
$comments = $_POST['comments'];


if(trim($name) == '') {
    echo '<div class="error_message">Attention! You must enter your name.</div>';
    exit();
} else if(trim($email) == '') {
    echo '<div class="error_message">Attention! Please enter a valid email address.</div>';
    exit();
} else if(trim($phone) == '') {
    echo '<div class="error_message">Attention! Please enter a valid phone number.</div>';
    exit();
} else if(!is_numeric($phone)) {
    echo '<div class="error_message">Attention! Phone number can only contain digits.</div>';
    exit();
} else if(!isEmail($email)) {
    echo '<div class="error_message">Attention! You have enter an invalid e-mail address, try again.</div>';
    exit();
} else if(trim($comments) == '') {
    echo '<div class="error_message">Comments one</div>';
    exit();
} else if(trim($newfield) == '') {
    echo '<div class="error_message">Comments two</div>';
    exit();
}

此处还有一张我提交时错误的图片。如果我删除这行代码，它可以工作但不捕获电子邮件的那个区域：

else if(trim($newfield) == '') {
        echo '<div class="error_message">Comments two</div>';
        exit();
    }
