我有一个插件，它可以拍摄快照并将jpg上传到服务器。现在，我正在使用函数date（"YmdHis"）。jpg’来命名文件。但是我想在我的html文件中给出文件名。我有4个文件：测试。HTLM与我的html，WEBCAM。JS和一些JS和TEST。带有服务器功能的PHP。我有一个webcam.swf文件，它将图片传递给TEST。PHP。
非常感谢！
这是我的代码：

<?php
/* JPEGCam Test Script */
/* Receives JPEG webcam submission and saves to local file. */
/* Make sure your directory has permission to write files as your web server user! */

您可以尝试将名称作为GET变量传递。在设置api url时添加您想要的文件名，如下所示：
webcam.set_api_url( 'test.php?filename=imagename' );
在PHP文件中
$filename = $_GET['filename'] . '.jpg';
