Öncelikle Bootstrap 5 sınıfını sistemimize ekliyoruz. ardından da form ile input=file oluşturup script sınıfımızı yazmaya başlıyoruz.

    </head>
    <body>

        <div class="container">
            <h1 class="mt-3 mb-3 text-center">Multiple File Upload with Progress Bar using JavaScript & PHP</h1>

            <div class="card">
                <div class="card-header">Select File</div>
                <div class="card-body">
                    <table class="table">
                        <tr>
                            <td width="50%" align="right"><b>Select File</b></td>
                            <td width="50%">
                                <input type="file" id="select_file" multiple />
                            </td>
                        </tr>
                    </table>
                </div>
            </div>
            <br />
            <div class="progress" id="progress_bar" style="display:none; ">

                <div class="progress-bar" id="progress_bar_process" role="progressbar" style="width:0%">0%</div>

            </div>

            <div id="uploaded_image" class="row mt-5"></div>
        </div>
    </body>
</html>

<script>

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

_('select_file').onchange = function(event){

    var form_data = new FormData();

    var image_number = 1;

    var error = '';

    for(var count = 0; count < _('select_file').files.length; count++)  
    {
        if(!['image/jpeg', 'image/png', 'video/mp4'].includes(_('select_file').files[count].type))
        {
            error += '<div class="alert alert-danger"><b>'+image_number+'</b> Selected File must be .jpg or .png Only.</div>';
        }
        else
        {
            form_data.append("images[]", _('select_file').files[count]);
        }

        image_number++;
    }

    if(error != '')
    {
        _('uploaded_image').innerHTML = error;

        _('select_file').value = '';
    }
    else
    {
        _('progress_bar').style.display = 'block';

        var ajax_request = new XMLHttpRequest();

        ajax_request.open("POST", "upload.php");

        ajax_request.upload.addEventListener('progress', function(event){

            var percent_completed = Math.round((event.loaded / event.total) * 100);

            _('progress_bar_process').style.width = percent_completed + '%';

            _('progress_bar_process').innerHTML = percent_completed + '% completed';

        });

        ajax_request.addEventListener('load', function(event){

            _('uploaded_image').innerHTML = '<div class="alert alert-success">Files Uploaded Successfully</div>';

            _('select_file').value = '';

        });

        ajax_request.send(form_data);
    }

};

</script>

Sıra geldik upload.php yani işin kalbine 

<?php

//upload.php

if(isset($_FILES['images']))
{
	for($count = 0; $count < count($_FILES['images']['name']); $count++)
	{
		$extension = pathinfo($_FILES['images']['name'][$count], PATHINFO_EXTENSION);

		$new_name = uniqid() . '.' . $extension;

		move_uploaded_file($_FILES['images']['tmp_name'][$count], 'images/' . $new_name);

	}

	echo 'success';
}


?>
