如何使用我的表单中存在的名称上传网络摄像头快照?

How can I upload a webcam snapshot with a name which is present in my form?

我有这个插件可以拍摄快照并将 jpg 上传到服务器。现在,我正在使用函数 date('YmdHis') 。 '.jpg' 来命名文件。但我想在我的 html 文件中提供文件名。我有 4 个文件:TEST.HTLM 和我的 html,WEBCAM.JS 和一些 JS,TEST.PHP 和服务器函数。我有 webcam.swf 文件将图片传递给 TEST.PHP。

非常感谢!

这是我的代码:

            webcam.set_shutter_sound( false ); // play shutter click sound
        </script>

PHP 文件

<?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! */

        $filename = date('YmdHis') . '.jpg';
        $result = file_put_contents( $filename, file_get_contents('php://input') );
        if (!$result) {
            print "ERROR: Failed to write data to $filename, check permissions\n";
            exit();
        }

        $url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['REQUEST_URI']) . '/' . $filename;

        print $_SERVER['REQUEST_URI'];

        ?>

在 PHP 文件中,它为正在上传的图像分配了随机名称,但我想从我的表单中分配一个名称如何执行此操作。

您可以尝试将名称作为 GET 变量传递。像这样设置 api url 时添加你想要的文件名:

webcam.set_api_url( 'test.php?filename=imagename' );

然后在 php 文件中:

$filename = $_GET['filename'] . '.jpg';

希望对您有所帮助。
