联系表格提交

Question

我是 php 的新手 - 我正在尝试使用提供的模板代码提交一个简单的联系表单。 我收到此错误报告：

致命错误：未捕获的错误：函数名称必须是 /home/u512372001/domains/thestripedphoenix.com/public_html/assets/php/mail.php:15 中的字符串：#0 {main} throw in /home/u512372001/ domain/thestripedphoenix.com/public_html/assets/php/mail.php 第 15 行

php 出了什么问题？

这是 HTML 表单代码：

                                    <form method="POST" action="assets/php/mail.php">

                                        <div class="row gtr-uniform">

                                                <input type="text" name="name" id="name" value="" placeholder="Name" />

表单提交的php代码：

<?php

error_reporting(E_ALL);
ini_set('display_errors', 1);



if(isset($_POST['submit'])) {
$to = "mymail@gmail.com";
$subject = "Subject Line";

        # Sender Data
        $name = str_replace(array("\r","\n"),array(" "," ") , strip_tags(trim($_POST["name"])));
        $email = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL);
        $category = $_POST(["category"]);
        $priority = $_POST(["priority"]);
        $message = trim($_POST["message"]);

        if ( empty($name) OR !filter_var($email, FILTER_VALIDATE_EMAIL) OR empty($message) OR empty($category)) {
            # Set a 400 (bad request) response code and exit.
            http_response_code(400);
            echo '<p class="alert alert-warning">Please complete the form and try again.</p>';
            exit;
        }

            # Mail Content
            $content = "Name: $name\r\n";
            $content .= "Email: $email\n\n";
            $content .= "I want a: $category\n\n";
            $content .= "Priority: $priority\n\n";
            $content .= "Message: $message\n\n";


            # Send the email.
            mail($to, $subject, $content);
            if ($success) {
                # Set a 200 (okay) response code.
                http_response_code(200);
                echo '<p class="alert alert-success">Thank You! Your message has been sent.</p>';
            } else {
                # Set a 500 (internal server error) response code.

                echo '<p class="alert alert-warning">Oops! Something went wrong, we couldnt send your message.</p>';
            }


    } else {
        # Not a POST request, set a 403 (forbidden) response code.
        http_response_code(403);
        echo '<p class="alert alert-warning">There was a problem with your submission, please try again.</p>';
    }



?>

从php表单来看，如果用户没有完整填写表单，那么就会出现验证错误信息。 提交所有必需的信息后，该消息应发送到我的电子邮件。

如果您需要进一步说明，请告诉我。 谢谢你的帮助！

Answer 1

您的代码有语法错误

这里：

$content .= "I want a: $category\n\n" // => missing ;
$content .= "Priority: $priority\n\n" // => missing ;

和这里：

        echo '<p class="alert alert-warning">Oops! Something went wrong, we couldnt send your message.</p>';
    }
} // => closing bracket not matching anything

启用显示错误

为了能够看到致命错误，如语法错误，请确保在php.ini启用display_errors 。 如果您不知道在哪里可以找到这个文件，您可以通过调用phpinfo()并在其输出中查找“加载的配置文件”来找到您的php.ini的位置。

对于所有非致命错误，您可以直接使用error_reporting()和display_errors()在脚本中启用显示错误：

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

在运行代码之前，使用像PHPStorm这样的 IDE 还可以帮助您格式化和显示错误。

Answer 2

错误在 mail.php 文件中的第 15 和 16 行：

您的代码：

$category = $_POST(["category"]);
$priority = $_POST(["priority"]);

更新科斯：

$category = $_POST["category"];
$priority = $_POST["priority"];

只需删除括号“（”，“）”

我在 form.php 文件中给你一个建议：使用按钮而不是这样的输入：

<button type="submit" name="submit">Submit
