Question

我正在尝试使用图像缩放器，我得到了以下代码

if (is_uploaded_file(@$_FILES['ulimage']['tmp_name'])){
        $targetfilename = ImageHelper::treatFilename(uniqid() . "_" . $_FILES['ulimage']['name']);
        move_uploaded_file($_FILES['ulimage']['tmp_name'], dirname(__FILE__) . "/tmp/" . $_FILES['ulimage']['name']);
        ImageHelper::resizeImage(dirname(__FILE__) . "/tmp/" . @$_FILES['ulimage']['name'], dirname(__FILE__) . "/tmp/" . $targetfilename, $width, $height);
    }

现在，原始图像和缩略图将放在同一个文件夹中。

让我知道..

嗯，答案是：

if (is_uploaded_file(@$_FILES['ulimage']['tmp_name']))
{
        $targetfilename = ImageHelper::treatFilename(uniqid() . "_" . $_FILES['ulimage']['name']);
        move_uploaded_file($_FILES['ulimage']['tmp_name'], dirname(__FILE__) . "/tmp/" . $_FILES['ulimage']['name']);
        ImageHelper::resizeImage(dirname(__FILE__) . "/tmp/" . @$_FILES['ulimage']['name'], dirname(__FILE__) . "/tmp/thumb/" . $targetfilename, $width, $height);
}

但也许你想在使用之前了解一下你从网上复制和过去的代码。使用$ _ vars而不转义系统并使用@来隐藏错误并不是真正需要信任...

编辑：我提出建议，但也许最好给出一些解释。

// first you check if the is done uploading in the tmp directory with is tmp name
if (is_uploaded_file(@$_FILES['ulimage']['tmp_name'])) 
{
     // here, you rebuild a explicit name using the original filename and a 
     // unique ID to avoid erasing another one   
     $targetfilename = ImageHelper::treatFilename(uniqid() . "_" . $_FILES['ulimage']['name']);

     // you rename the file an put it in ./tmp, a subdir of the 
     // script file (because of dirname(__FILE__))
     move_uploaded_file($_FILES['ulimage']['tmp_name'], dirname(__FILE__) . "/tmp/" . $_FILES['ulimage']['name']);

    // Here create a rezided copy
    // so it's here you can decide to make it go to ./tmp/thumb
    // make sure the dir exists before because you have no clue here
    // if ImageHelper will create it for you if not
    ImageHelper::resizeImage(dirname(__FILE__) . "/tmp/thumb/" . @$_FILES['ulimage']['name'], dirname(__FILE__) . "/tmp/thumb/" . $targetfilename, $width, $height);
}

嘿，伙计，这看起来非常艰难，但可以简单地使用Thumbnailer库及其上传助手：

function callback(& $thumb) {
   $thumb->thumbSquare(100)->save("/tmp/thumb/".$thumb->filename);
}

Thumbnailer::upload('ulimage', 'callback');

非常简单：）

如何使缩略图转到/ tmp / thumb /并使用Image Resizer将原始图像保留在/ tmp /上？
