Question

我有一个网站，用户可以上传图片（几天前工作完美，我甚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，我也尝试了777权限，因此不应该是它无法正常工作的原因。

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
＆＃34;没有错误，文件上传成功。
图像上传。＆＃34;
但是文件没有改变/出现在服务器上。

我也可以删除$ writeimage = fopen（$ imgPath，＆＃34; w＆＃34;）;和fclose（$ writeImage），可以吗？

Answer 1

此部分存在问题

$writeimage = fopen($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);

请勿在您希望执行其他文件操作的路径上调用fopen。此外，您在if检查中将逻辑颠倒了。如果移动成功，则记录＆＃34; 无法移动img ＆＃34;。请改用：

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，您还遇到了其他一些问题，我已在此处修复过这些问题。

您在echo，
您使用括号echo（您不应该
您已将$image切换为$imgPath

Answer 2

在您的代码中，我可以看到一些问题。

//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变量的定义在哪里？它应该是$ image。无需使用fopen和fclose

所以你的cose shouled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>");
    }
}

PHP上传不起作用，没有错误
