PHPMailer - 代码似乎什么都不做

Question

我需要帮助，我收到一个未定义的错误，它肯定是由我的代码处理PHP文件顶部的附件引起的。我知道这一点，因为如果我发表评论，我就不会收到这个错误。

接下来我正在使用XAMPP，我在php.ini文件和C：//xampp/sendmail/senmail.ini设置中使用了几个教程来获取sendmail，所以我希望它实际上会发送一封电子邮件当我测试表格时通过gmail，但我还没有通过。

我不知道从哪里开始，我已经使用了两个教程来制作我的PHP代码，请看一下。

<?php
header('Content-type: application/json');
$status = array(
    'type'=>'success',
    'message'=>'Thank you for contact us. As early as possible  we will contact you '
);

//Added to deal with Files
require_once('../PHPMailer/class.phpmailer.php')
    //Get the uploaded file information
    $name_of_uploaded_file =
        basename($_FILES['uploaded_file']['name']);

    //get the file extension of the file
    $type_of_uploaded_file =
        substr($name_of_uploaded_file,
        strrpos($name_of_uploaded_file, '.') + 1);

    $size_of_uploaded_file =
        $_FILES["uploaded_file"]["size"]/1024;//size in KBs

    //Settings
    $max_allowed_file_size = 10240; // size in KB
    $allowed_extensions = array("jpg", "jpeg", "gif", "bmp","png");

    //Validations
    if($size_of_uploaded_file > $max_allowed_file_size )
    {
      $errors .= "\n Size of file should be less than $max_allowed_file_size (~10MB). The file you attempted to upload is too large. To reduce the size, open the file in an image editor and change the Image Size and resave the file.";
    }

    for($i=0; $i<sizeof($allowed_extensions); $i++)

首先;在发回JSON响应之前，您将返回一个布尔标志。返回值后，将忽略 return 关键字下方的任何语句。因此，您可能无法获得所需的结果。第二;您可能需要明确告诉PHPMailer如何发送电子邮件。第三，你忘记了require_once行上的结束半结肠（;）。下面的代码有注释，表明您可能错过了什么：

    <?php
        header('Content-type: application/json');

        // WE SHOULD ASSUME THAT THE EMAIL WAS NOT SENT AT FIRST UNTIL WE KNOW MORE.
        // WE ALSO ADD AN ATTACHMENT KEY TO OUR STATUS ARRAY TO INDICATE THE STATUS OF OUR ATTACHMENT:  
        $status = array(
            'type'          =>'Error',
            'message'       =>'Couldn\'t send the Email at this Time. Something went wrong',
            'attachement'   =>'Couldn\'t attach the uploaded File to the Email.'
        );

        //Added to deal with Files
        // YOU MISSED A CLOSING SEMI-COLON HERE... ;-)
        require_once('/PHPMailer/class.phpmailer.php');  //Double check this path
        //Get the uploaded file information
        $name_of_uploaded_file =
            basename($_FILES['uploaded_file']['name']);

        //get the file extension of the file
        $type_of_uploaded_file =
            substr($name_of_uploaded_file,
                strrpos($name_of_uploaded_file, '.') + 1);

        $size_of_uploaded_file =
            $_FILES["uploaded_file"]["size"]/1024;//size in KBs

        //Settings
        $max_allowed_file_size = 10240; // size in KB
        $allowed_extensions = array("jpg", "jpeg", "gif", "bmp","png");

        //Validations
        if($size_of_uploaded_file > $max_allowed_file_size )
