PHP T- HTML表单中的变量

Question

下面的代码在第10行抛出了一个T变量异常

 //Two Email Lines
$email_to = "contact@website.com";
$email_subject = "AUTO: WEB BETA INVITE REQUEST";

//Set equal to email form textbox
$email_form = $_POST["email_text"];



$email_message = "Email: "$email_form"";

//Create email headers
$headers = 'From: '.$email_form."\r\n".
@mail($email_to, $email_subject,$email_message,$headers);

当我将变量$email_form两边的= "Email："$email_form""；改为单引号时，它就会运行并抛出任何异常。但是，它会发送一封电子邮件，上面写着" email：''"，就像在中一样，它将$email_form变量读取为空，但实际上并非如此。

表单的HTML代码如下所示。

<form method="post" action="Email_Form_Script.php" enctype="text/plain" onsubmit="window.open('FormPopUp.html','popup','width=500,height=500,scrollbars=no,resizable=no,toolbar=no,directories=no,location=no,menubar=no,status=no,left=0,top=0');" >
<div><input type="text" class="text" name="email_text" id="emailForm" value="Enter your e-mail address" onfocus="if(this.value=='Enter your e-mail address') { this.value = '' }" onblur="if(this.value=='') { this.value = 'Enter your e-mail address' }" /><input type="hidden" value="" name="email2"/><input type="hidden" name="loc" value="en_US"/><input type="submit" class="submit" value="" 
            /></div></form>

谢谢你的帮助

Answer 1

更改：

$email_message = "Email: "$email_form"";

至：

$email_message = "Email: " . $email_form . "";

你忘了拼接。

Answer 2

变化

$email_message = "Email: "$email_form"";

至

$email_message = "Email: " . $email_form . "";

而且看起来你还少了一个分号：

//Create email headers
$headers = 'From: '.$email_form."\r\n". <---
