Question

形式：

<form enctype="multipart/form-data" action="FileUpload.php" method="post">
                    <label for="file" class="myLabel">Select File</label>
                    <input type="file" id="file" name="fileUpload">
                    <input type="submit" class="submit" value="Upload File">

            </form>

PHP：

if(isset($_FILES['fileUpload'])){
        $uploadName = $_FILES['fileUpload']['name'];
        $uploadTmp = $_FILES['fileUpload']['tmp_name'];
        $fileSize = $_FILES['fileUpload']['size'];
        $fileType = pathinfo($uploadName, PATHINFO_EXTENSION);
        $uploadName = trim($uploadName, "." . $fileType);

        $uploadName = preg_replace("#[^a-z0-9.]#i","",$uploadName);//removes all spaces in their name

        $uploadName = mt_rand(100000,999999) . "____" . $uploadName;//generates random number in front of name so multiple files of the smae name can be uploaded

        if(($fileSize > 100024352638512 )){//check file is less than 10gb   
            die("Error - File to big");
        }

        if(!$uploadTmp){//checks to see if file is selected
            die("No File Selected, Please Upload Again");
        }else{
            move_uploaded_file($uploadTmp,"uploads/$uploadName");//puts file into uploads directory
        }

    $sql = $con->query("INSERT INTO uploads (ID, Time ,Name, Type, Owner) VALUE
    (NULL,CURRENT_TIMESTAMP(),'{$uploadName}','{$fileType}','{$_SESSION['UserID']}')")or die(mysqli_error($con));//inserts file into database

        header("Location:Profile.php");//sends you to profile page
        }

代码执行到最后但文件没有上传到数据库，我之前有php工作，但我改变了输入按钮的工作方式，现在它不起作用。我会感激任何帮助，因为我还是一个新开发者。

Answer 1

看来你正试图在你的ID列中插入NULL，我假设它是你的主键。

SQL Server, can't insert null into primary key field?

您不能将NULL插入主键，而应该跳过尝试将任何内容放入ID列。

Answer 2

按照Lucha Laura的回答 - 如果文件正在上传并成功移动，我会怀疑您插入的值违反了数据库字段＆＃39;约束

在主键中插入NULL在MySQL中有效，但其他字段可能配置不正确。检查字段的字段类型，长度和not_null要求，并确保它们接受您要发送的值。预览实际值的一种简单方法是使用error_log()将错误日志发送到错误日志。

略有不相关 - trim()并没有做你想要完成的事情。查看strstr()或preg_replace()。

表单中的文件信息未传递给php
