通過HTML5和PHP中的聯繫表單發送文件

Question

在問我的問題之前，請允許我說我目前不是PHP開發人員。我對PHP有一點經驗，但我的背景主要是HTML5，CSS3，SASS，JS，JQuery，Basic PHP。

考慮到這一點，這是我的問題。目前我有一個基於html5的表單，我正在使用它來解析名稱和收件人電子郵件字段並附加文檔。

我有電子郵件發送和文檔，但無論我發送哪種文檔類型它通過作爲txt文件並且文件本身總是空的。所以我的問題是爲什麼？/我究竟做錯了什麼？

我知道我需要做的其他事情的形式，即驗證，驗證碼等，但在這個階段，我只想發送完整的文件。

下面是我到目前爲止，請原諒任何格式的問題：

HTML5

<form role="form" action="addDocument.php" method="post" onsubmit="return validateForm()"> 
    <!-- file browse and upload--> 
    <div class="form-group"> 
     <input type="file" name="file" class="file"> 
     <div class="input-group col-xs-12"> 

      <span class="input-group-addon"><i class="fa fa-file-image-o"></i></span>          
      <input type="text" class="form-control input-lg" disabled placeholder="Upload Image"> 

      <span class="input-group-btn"> 
       <button class="browse btn btn-primary input-lg" type="button"><i class="fa fa-search"></i> Browse</button> 
      </span> 
     </div> 
    </div> 
    <div class="form-group"> 
     <label class="sr-only" for="c-form-1-name">Name</label> 
     <input id="c-form-1-name" class="c-form-1-name form-control" name="name" placeholder="Name..." type="text"> 
    </div> 
    <div class="form-group"> 
     <label class="sr-only" for="c-form-1-email">Recipient Email</label> 
     <input id="c-form-1-email" class="c-form-1-email form-control" name="remail" placeholder="Recipient Email..." type="text"> 
    </div>  
    <button class="btn btn-primary btn-lg btn-block" type="submit">Send</button> </form>

     } 

     // send 
     return @mail($recipientEmail, $subject, $message, $headers); 

    } 
}

在這裏，你需要添加enctype="multipart/form-data"形成如果你想發佈任何文件/圖片

從

<form role="form" action="addDocument.php" method="post" onsubmit="return validateForm()"> 

到

<form role="form" enctype="multipart/form-data" action="addDocument.php" method="post" onsubmit="return validateForm()">
