如何在 PHP 中上传显示进度条的视频文件

Question

我想使用 PHP 上传视频文件并通过进度条显示上传进度。但这比我想的更难，我试图把我找到的部分放在一起，但不幸的是，我没有找到一个完全包含所需 PHP、Ajax 和 HTML 代码的工作代码，所以我试过了把不同的部分放在一起。 @fahad

上传表单是表单的名称.. ("progressBar") 是你的进度条 使用它，如果您有任何问题，请告诉我

function _(el) {
    return document.getElementById(el);
}

$('#uploadForm').submit((event) => {
    event.preventDefault()
    var form = document.getElementById("uploadForm"),
        formdata = new FormData(form);
    var ajax = new XMLHttpRequest();
    ajax.upload.addEventListener("progress", progressHandler, false);
    ajax.addEventListener("load", completeHandler, false);
    ajax.addEventListener("error", errorHandler, false);
    ajax.addEventListener("abort", abortHandler, false);
    ajax.open("POST", "upload-media");
    ajax.send(formdata);

    function formatBytes(bytes, decimals) {
        if (bytes == 0) return '0 Bytes';
        var k = 1024,
            dm = decimals <= 0 ? 0 : decimals || 2,
            sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'],
            i = Math.floor(Math.log(bytes) / Math.log(k));
        return parseFloat((bytes / Math.pow(k, i)).toFixed(dm)) + ' ' + sizes[i];
    }

    function progressHandler(event) {
        _("loaded_n_total").innerHTML = `Uploaded ${formatBytes(event.loaded)} of ${formatBytes(event.total)}`;
        var percent = event.loaded / event.total * 100;
        _("progressBar").style.width = `${Math.round(percent)}%`;
        _("status").innerHTML = `${Math.round(percent)}% uploaded... please wait`;
        _('submit').setAttribute('disabled', 'disabled');

    }

    function completeHandler(event) {
        var res = JSON.parse(event.target.response);
        _("titleView").innerHTML = `${res.title}`;
        _('total').innerHTML = `${formatBytes(res.fileSize)}`;
        _("statuses").innerHTML = `video Uploaded successfully`;
        _("status").innerHTML = `video Uploaded successfully file name is ${res.video}`;
        _("imgplace").innerHTML = `<img src="thumbnail/${res.thumbnail}">`;
        _("progressBar").style.width = "0";
        _("uploadForm").reset();
        _("submit").removeAttribute('disabled', 'disabled');

    }

    function errorHandler(event) {
        _("status").innerHTML = "Upload Failed";
    }

    function abortHandler(event) {
        _("status").innerHTML = "Upload Aborted";
    }
})

你可以用 Javascript 监听 ajax 的进度事件
