PHP 上传失败，没有错误

Question

我有一个用户可以上传图片的网站（几天前运行良好，我什至没有更改与上传相关的任何内容）

文件所有权设置为 www-data，我还尝试了 777 权限，所以这不应该是它不起作用的原因。

enctype/data 等也设置

这是代码：

switch ($_FILES['upload']['error']) {
            case UPLOAD_ERR_OK:
                $msg="There is no error, the file uploaded with success.";
                break;
            case UPLOAD_ERR_INI_SIZE:
                $msg="The uploaded file exceeds the upload_max_filesize directive in php.ini.";
                break;
            case UPLOAD_ERR_FORM_SIZE:
                $msg="The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.";
                break;
            case UPLOAD_ERR_PARTIAL:
                $msg="The uploaded file was only partially uploaded.";
                break;
            case UPLOAD_ERR_NO_FILE:
                $msg="No file was uploaded.";
                break;
            case UPLOAD_ERR_NO_TMP_DIR:
                $msg="Missing a temporary folder. Introduced in PHP 5.0.3.";
                break;
            case UPLOAD_ERR_CANT_WRITE:
                $msg="Failed to write file to disk. Introduced in PHP 5.1.0.";
                break;
           default:
               $msg="unknown error with upload";
       }
       echo("<script>console.log('".$msg."'); </script>");


        //process image
        if($_FILES['upload']['tmp_name']!=null){
            $imgPath="../assets/img/horses/horse".$id.".jpg";
            if((bool)getimagesize($_FILES["upload"]["tmp_name"])){
                $writeimage = fopen($imgPath, "w");
                if(!move_uploaded_file($_FILES["upload"]["tmp_name"], $imgPath)){
                    echo("<script>console.log('couldn't move img');</script>");
                } else{
                    echo("<script>console.log('image uploaded');</script>");
                }
                fclose($writeimage);
            } else{
                echo("  <div class='alert alert-warning' id='notSaved' style='margin-top:20px;'>
                            Fehler: Die Datei die hochgeladen werden soll, scheint kein Bild zu sein.
                        </div>");
            }
        }

输出是
"没有错误，文件上传成功。
图片已上传。”
但是文件 change/appear 服务器上没有。

我也可以删除 $writeimage = fopen($imgPath, "w");和 fclose($writeImage)，我不能吗？

Answer 1

这部分有问题

$writeimage = fopen($imgPath, "w");
if(move_uploaded_file($_FILES["upload"]["tmp_name"], $imgPath)){
    echo("<script>console.log('couldn't move img');</script>");
} else{
    echo("<script>console.log('image uploaded');</script>");
}
fclose($writeimage);

不要在您希望执行其他文件操作的路径上调用 fopen。此外，您在 if 检查中的逻辑颠倒了。如果移动成功，您将记录“无法移动 img”。改用这个：

if(!move_uploaded_file($_FILES["upload"]["tmp_name"], $image)){
    echo '<script>console.log("couldn\'t move img");</script>';
} else{
    echo '<script>console.log("image uploaded");</script>';
}

请注意，您还遇到了我已在此处修复的其他几个问题。

您没有在 echo、
您在 echo 中使用了括号（您不应该）
您将 $image 切换为 $imgPath

Answer 2

在你的代码中，我发现了一些问题。

//process image
if($_FILES['upload']['tmp_name']!=null){
    $image="../assets/img/horses/horse".$id.".jpg";
    if((bool)getimagesize($_FILES["upload"]["tmp_name"])){
        $writeimage = fopen($imgPath, "w");
        if(move_uploaded_file($_FILES["upload"]["tmp_name"], $imgPath)){
            echo("<script>console.log('couldn't move img');</script>");
        } else{
            echo("<script>console.log('image uploaded');</script>");
        }
        fclose($writeimage);
    } else{
        echo("  <div class='alert alert-warning' id='notSaved' style='margin-top:20px;'>
                    Fehler: Die Datei die hochgeladen werden soll, scheint kein Bild zu sein.
                </div>");
    }
}

请检查$imgPath 变量是在哪里定义的？它应该是$图像。无需使用 fopen 和 fclose

所以你的密码应该是...

if($_FILES['upload']['tmp_name']!=null){
    $image="../assets/img/horses/horse".$id.".jpg";
    if((bool)getimagesize($_FILES["upload"]["tmp_name"])){
        if(move_uploaded_file($_FILES["upload"]["tmp_name"], $image)){
            echo("<script>console.log('couldn't move img');</script>");
        } else{
            echo("<script>console.log('image uploaded');</script>");
        }
    } else{
        echo("  <div class='alert alert-warning' id='notSaved' style='margin-top:20px;'>
                    Fehler: Die Datei die hochgeladen werden soll, scheint kein Bild zu sein.
                </div>");
    }
}
