使用 php 直接联系表格以通过电子邮件发送自己

Question

我尝试了很多方法来解决这个问题，但似乎我碰壁了。它应该以这种方式工作，但我找不到任何错误，因为它写的是有一个

语法错误，意外的 $end

点击提交按钮后。

首先，我这样输入代码。

<form class="form" method="post" action="sendContact.php">  
                <table>
                    <tr>
                        <td class="contact-firstcol"> <label for="name">Name</label> </td>
                        <td class="contact-secondcol"> : </td>
                        <td class="contact-thirdcol"> <input type="text" name="name" id="name" /> </td>
                    </tr>
                    <tr>
                        <td class="contact-firstcol"> <label for="email">Email</label> </td>
                        <td class="contact-secondcol"> : </td>
                        <td class="contact-thirdcol"> <input type="text" name="email" id="email" /> </td>
                    </tr>
                    <tr>
                        <td class="contact-firstcol"> <label for="phone">Phone</label> </td>
                        <td class="contact-secondcol"> : </td>
                        <td class="contact-thirdcol"> <input type="text" name="phone" id="phone" /> </td>
                    </tr>
                    <tr>
                        <td class="contact-firstcol"> <label for="message">Message</label> </td>
                        <td class="contact-secondcol"> : </td>
                        <td class="contact-thirdcol"> <textarea id="message" name="message"></textarea> </td>
                    </tr>
                    <tr>
                        <td class="contact-firstcol"></td>
                        <td class="contact-secondcol"></td>
                        <td class="contact-thirdcol"> <input type="submit" name="submit" value="SUBMIT" /> </td>
                </table>    
            </form>

这个文件名为 sendContact.php

         <?php
            $to = 'abc@abc.com';
            $subject = 'from email contact';

            $name = $_POST ['name'];
            $email = $_POST ['email'];
            $phone = $_POST ['phone'];
            $message = $_POST ['message'];

            $body = <<< EMAIL
            Hi! My name is $name
            $message.
            From : $name
            Email : $email
            Topic : $topic
            EMAIL;
            $header = "From: $email";

            if (isset($_POST)) {
                if ($name == '' || $email == '' || $topic == '' || $message = '') {
                    $feedback = 'Please fill in any fields.';

                } else {

                mail( $to, $subject, $body, $header);
                $feedback = 'Thanks for the information, we will get back to you in 24 hours.';
                }
            }
?>
<p class="feedback"> <?php echo $feedback ?> </p>

我已经做到了如此简单，并确保电子邮件中的详细信息易于阅读。你能指出上面的任何错误吗？

干杯

Answer 1

<<< EMAIL中的<<<和EMAIL之间不能有空格

必须是<<<EMAIL（更多信息请参见脚注）

咨询：

http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc

有关heredoc的更多信息

示例 #1 无效示例（来自手册）

<?php
class foo {
    public $bar = <<<EOT
bar
    EOT;
}
?>

Example #2 Heredoc 字符串引用示例

<?php
$str = <<<EOD
Example of string
spanning multiple lines
using heredoc syntax.
EOD;

/* More complex example, with variables. */
class foo
{
    var $foo;
    var $bar;

    function foo()
    {
        $this->foo = 'Foo';
        $this->bar = array('Bar1', 'Bar2', 'Bar3');
    }
}

$foo = new foo();
$name = 'MyName';

echo <<<EOT
My name is "$name". I am printing some $foo->foo.
Now, I am printing some {$foo->bar[1]}.
This should print a capital 'A': \x41
EOT;
?>

Example #3 Heredoc in arguments 示例

<?php
var_dump(array(<<<EOD
foobar!
EOD
));
?>

在你的情况下：（我测试并工作）

我把$topic改成了$phone，否则会报错。

您需要进一步修改您的 PHP 以反映适当的更改。

<?php
$to = 'abc@abc.com';
$subject = 'from email contact';

$name = $_POST ['name'];
$email = $_POST ['email'];
$phone = $_POST ['phone'];
$message = $_POST ['message'];

$body = <<<EMAIL
Hi! My name is $name
$message.
From : $name
Email : $email
Topic : $topic
EMAIL;
$header = "From: $email";

if (isset($_POST)) {
    if ($name == '' || $email == '' || $phone == '' || $message = '') {
        $feedback = 'Please fill in any fields.';

    } else {

    mail( $to, $subject, $body, $header);
    $feedback = 'Thanks for the information, we will get back to you in 24 hours.';
    }
}
?>
<p class="feedback"> <?php echo $feedback ?> </p>

正如 Kostis 在评论中所说 --- “它是结束标记，前面不能有任何空格。认识到结束标识符之前的第一个字符必须是由定义的换行符也很重要本地操作系统。”
