Question

我正在尝试将pdf上传到数据库。我一直收到“上传文件时出错”错误。非数据也会插入到数据库中。

请问那些对PHP和SQL不那么陌生的人看看并告诉我哪里出错了。

稍后我将尝试将几个pfds合并在一起，然后将新的合并pdf保存到数据库中。

表格的SQL

CREATE TABLE `tbl_request` (
  `InvoiceNum` int(11) NOT NULL,
  `userEmail` varchar(25) NOT NULL,
  `Progress` enum('Uploaded','Verified and Awaiting Payment','Submitted to Department','Closed') NOT NULL DEFAULT 'Uploaded',
  `UploadDate` datetime NOT NULL,
  `FileName` varchar(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1 ROW_FORMAT=COMPACT;

PHP代码

<?php
session_start();
require_once 'class.user.php';
$user_home = new USER();

if(!$user_home->is_logged_in())
{
    $user_home->redirect('index.php');
}

if($_SESSION['userRole'] !== ('user'))
{
    $user_home->redirect('index.php');
}

$stmt = $user_home->runQuery("SELECT * FROM tbl_users WHERE userID=:uid");
$stmt->execute(array(":uid"=>$_SESSION['userSession']));
$row = $stmt->fetch(PDO::FETCH_ASSOC);

?>

Answer 1

所以我最终得到了我的代码，这里适用于任何可能需要在将来做同样事情的人。

<?php
        if(isset($_POST['btn-upload']))
    {  

    if ($_FILES['file']['type'] == "application/pdf") {  
        $link = mysqli_connect("localhost", "root", "", "test");
        $update=date("Ymdhis");
        $mail =$row['userEmail'];
        $sql="INSERT INTO tbl_request(userEmail,uploadDate) VALUES('$mail','$update')";
        mysqli_query($link,$sql);
        $file = $update."-".$_FILES['file']['name'];
        $file_loc = $_FILES['file']['tmp_name'];
        $folder="upload/";
        $final_file = strtolower($file);
        //$final_file=str_replace(' ','-',$new_file_name);  

        if(move_uploaded_file($file_loc,$folder.$final_file))       {

            $sql2="UPDATE tbl_request SET FileName ='".$final_file."' WHERE uploadDate = '".$update."'";
            mysqli_query($link,$sql2);
            ?>
            <script>
            alert('successfully uploaded');
            //window.location.href='index.php?success';
            </script>
            <?php
        }
        else
        {
            ?>
            <script>
            alert('error while uploading file');
            //window.location.href='index.php?fail';
            </script>
            <?php
        }
    }
    else{
    ?>
            <script>
            alert('Only pdf files may be uploaded');
            //window.location.href='index.php?fail';
            </script>
            <?php
    }
}
?>

我想改变的两件事：

$link = mysqli_connect("localhost", "root", "", "test"); mysqli_query($link,$sql);我确信有办法从dbconfig.php获取此信息（我只是不确定如何）
我希望人们能够上传3个pdf，然后使用php代码将它们合并为一个然后像上面一样保存的代码。

Answer 2

从技术上讲，您不是将pdf存储在数据库中，而是仅存储对文件存储位置的引用。因此，为了得到您所获得的错误，您的if(move_uploaded_file($file_loc,$folder.$final_file))必定会失败，可能是路径问题，看起来您正在指定相对路径，

try an absolute (full path) ie windows C:\folder\ or linux /home/user/public_html/uploads/

上传PDF并保存到数据库
