表单操作字段无法一起上传和移动到新页面

编辑：@James解决方案的答案在下面的代码中加粗。 再次感谢@James。

我有一个表单（HTML），它有一个文本字段并将文件上传到数据库。 在我使用之前

    <form action="<?php echo $_SERVER['PHP_SELF']?>" method="POST" name="form1" enctype="multipart/form-data"></pre>

它工作正常，现在我希望页面将条目提交到数据库并显示不同的页面，所以我尝试了这个

    <form action="page3.php"......>, but didn't worked.

但是，当我单击“提交”按钮时，它会在数据库中输入文本字段，但不会将文件上载到数据库。 我想要它做的是：当我点击提交按钮时，文本字段被输入数据库，文件被上传到数据库文件夹（我的程序使其路径进入数据库），以及为用户加载的新页面

感谢任何帮助。谢谢。 我的PHP代码

    <?php

    //ob_start();
    $host="localhost";
    $username="root";
    $password="";
    $db_name="newrep";
    $table_name="members";

    $conn=new mysqli('localhost','root','','newrep');
    if(!$conn){
        die("cannot connect.");
    }
    //else if(!mysql_select_db($db_name)){
      //  die(" cannot select database.");
    //}

    session_start();
    use foundationphp\UploadFile;
    echo "Session value: ".$_SESSION['texas'];
    $currentuser=$_SESSION['texas'];
     echo $currentuser;
     $current_year=date("Y");

     //code for upload starts here
    require_once 'src/foundationphp/UploadFile.php';
    if (!isset($_SESSION['maxfiles'])) {
    $_SESSION['maxfiles'] = ini_get('max_file_uploads');
    $_SESSION['postmax'] = UploadFile::convertToBytes(ini_get('post_max_size'));
    $_SESSION['displaymax'] = UploadFile::convertFromBytes($_SESSION['postmax']);
    }
    $max = 2048 * 1024;
    $result = array();
    //upload code ended above
    if(!isset($_SESSION['texas'])) 
    {
      header('Location:login_page.php');
      exit();
   }
   else {
    if(isset($_POST['title'])){
      echo "reaching the else";

        print_r($_FILES);

      try {
      $upload = new UploadFile($destination);
      $upload->setMaxSize($max);
      //$upload->allowAllTypes();
      $upload->upload();
      $result = $upload->getMessages();
        } 
      catch (Exception $e) {
        $result[] = $e->getMessage();
        }

    if ($result) {
    foreach ($result as $message) {
    echo "<li>$message</li>";}}}

    $file_path_variable= $destination.$_SESSION['current_filename'];
    echo $file_path_variable;

    $title=$_POST['title'];

    $query="INSERT INTO proposal(title_prop, userName_prop,whitepaper_prop,year_prop) VALUES('$title','$currentuser','$file_path_variable','$current_year')";

    $result_query=mysqli_query($conn,$query);

   echo "      in elseif         ";
    if(!$result_query){
      echo " cannot insert ";
    }
    else {
**header('Location: page3.php');
exit();**
      //echo "successful entry ";
    }
   }
    //ob_end_flush();

您需要在表单标记中加入enctype='multipart/form-data'：

<form action='<?php echo $_SERVER['PHP_SELF']?>' method="POST" name="form1" enctype='multipart/form-data'>

没有它，附件就无法通过表单发送。

尝试以下代码。我也修复了一些HTML错误。

<?php

    //ob_start();
    $host="localhost";
    $username="root";
    $password="";
    $db_name="newrep";
    $table_name="members";

    $conn=new mysqli('localhost','root','','newrep');
    if(!$conn){
        die("cannot connect.");
    }
    //else if(!mysql_select_db($db_name)){
      //  die(" cannot select database.");
    //}

    session_start();
    use foundationphp\UploadFile;
    echo "Session value: ".$_SESSION['texas'];
    $currentuser=$_SESSION['texas'];
    echo $currentuser;
    $current_year=date("Y");

    //code for upload starts here
    require_once 'src/foundationphp/UploadFile.php';
    if (!isset($_SESSION['maxfiles'])) {
        $_SESSION['maxfiles'] = ini_get('max_file_uploads');
        $_SESSION['postmax'] = UploadFile::convertToBytes(ini_get('post_max_size'));
        $_SESSION['displaymax'] = UploadFile::convertFromBytes($_SESSION['postmax']);
    }

    $max = 2048 * 1024;
    $result = array();
    //upload code ended above
    if(!isset($_SESSION['texas'])) 
    {
        header('Location:login_page.php');
        exit();
    }else {

            $query="INSERT INTO proposal(title_prop, userName_prop,whitepaper_prop,year_prop) VALUES('$title','$currentuser','$file_path_variable','$current_year')";
