拖放图像并将其上传到多个文件夹

Drag drop image & upload it on multiple folder

本文关键字：文件夹 图像 拖放      更新时间：2023-09-26

现在我正在通过在字段上拖动图像来执行图像上传操作，并成功将其上传到目标。现在我需要在多个文件夹上上传相同的图像，同时将图像拖到字段中，图像应该插入多个文件夹中。当我尝试在多个文件夹上上传相同的图像时，就会出现问题，图像入到第一个文件夹中而不是其他文件夹中。我附上了下面的代码。

function uploadimage() {
    $headerimage=array();
    if (!empty($_FILES)) {
        $headerimage[0] = 'uploadimages/post_ads'."/".$_FILES['file']['name'];
        echo move_uploaded_file($_FILES['file']['tmp_name'],$headerimage[0]);
        $headerimage[1] = 'uploadimages/latestimages'."/".$_FILES['file']['name'];
        echo move_uploaded_file($_FILES['file']['tmp_name'],$headerimage[1]);
        $headerimage[2] = 'uploadimages/listimages'."/".$_FILES['file']['name'];
        echo move_uploaded_file($_FILES['file']['tmp_name'],$headerimage[2]);
        $headerimage[3]  = 'uploadimages/photoimages'."/".$_FILES['file']['name'];
        //$headerpath = 'uploadimages/photoimages'."/".$_FILES['file']['name'];
        echo move_uploaded_file($_FILES['file']['tmp_name'],$headerimage[3]);
        $headerimage[4]  = 'uploadimages/slideimages'."/".$_FILES['file']['name'];
        //$headerpath = 'uploadimages/slideimages'."/".$_FILES['file']['name'];
        echo move_uploaded_file($_FILES['file']['tmp_name'],$headerimage[4]);
        print_r($headerimage);
        $_SESSION['upload_images'][]=$headerimage;
    }
}

在post_ads文件夹中插入图像，但在其他文件夹中没有。你们中的任何人可以向我建议一个可能的解决方案吗？

move_uploaded_file将移动文件，而不是复制它 - 这意味着它只会工作一次。

如果您使用的是 copy，则复制的次数根本不应该有任何限制：上传创建的 temporay 文件只会在脚本执行结束时销毁（当然，除非您之前移动/删除它）

不过，也许解决方案是先使用move_uploaded_file，然后再复制？有点像，我想：

if (move_uploaded_file($_FILES['file']['tmp_name'],$headerimage[1])) {
    copy($headerimage[1], $headerimage[2]);
    copy($headerimage[1], $headerimage[3]);
    copy($headerimage[1], $headerimage[4]);
}

有一些很好的 php 库来处理上传。 我正在使用 http://www.verot.net/php_class_upload.htm 它简化了您的工作。 您可以将文件上传到多个文件夹，然后像：

include('class.upload.php');
//--------------------------------------
$upload_handler = new Upload($_FILES['file']); 
if ($upload_handler->uploaded)
{
$new name = time().rand(10000,99999);
//----------------------------------------
$upload_handler->image_convert = 'jpg';
$upload_handler->jpeg_quality = 70;
$upload_handler->image_background_color = '#FFFFFF';
$upload_handler->image_resize = true;
$upload_handler->file_new_name_body = $new name;
$upload_handler->image_ratio_fill = true;
$upload_handler->image_ratio_no_zoom_in = true;
$upload_handler->image_x = 900;
$upload_handler->image_y = 700;
$upload_handler->Process('folder_path_1');
//-----------------------------------------
$upload_handler->image_convert = 'jpg';
$upload_handler->jpeg_quality = 70;
$upload_handler->image_background_color = '#FFFFFF';
$upload_handler->image_resize = true;
$upload_handler->file_new_name_body = $new name;
$upload_handler->image_ratio_fill = true;
$upload_handler->image_ratio_no_zoom_in = true;
$upload_handler->image_x = 150;
$upload_handler->image_y = 150;
$upload_handler->Process('folder_path_2');
//-----------------------------------------     
}

因此，您可以调整大小，重新采样等，然后根据需要为不同的文件夹调用Process多少次。

谢谢你们

的建议。我已经找到了准确而简单的方法。我附上了下面的代码

function uploadimage()
{
if (!empty($_FILES)) {

        $headerimage= 'uploadimages/featuredimages'."/".$_FILES['file']['name'];
        $headerimage1= 'uploadimages/latestimages'."/".$_FILES['file']['name'];
        $headerimage2 = 'uploadimages/listimages'."/".$_FILES['file']['name'];
        $headerimage3  = 'uploadimages/photoimages'."/".$_FILES['file']['name'];
        $headerimage4  = 'uploadimages/slideimages'."/".$_FILES['file']['name'];
        $headerimage5  = 'uploadimages/galleryimages'."/".$_FILES['file']['name'];

          move_uploaded_file($_FILES['file']['tmp_name'],$headerimage);
          copy($headerimage,  $headerimage1 );
          copy($headerimage1,  $headerimage2 );
          copy($headerimage1, $headerimage3 );
          copy($headerimage1,$headerimage4 );
          copy($headerimage1,$headerimage5 );

    $_SESSION['upload_images'][]=$headerimage1;
}
}
