upload_form.html：

<!DOCTYPE html> <html> <head> <script> function _(el){ return document.getElementById(el); } function uploadFile(){ var file = _("file1").files[0]; // alert(file.name+" | "+file.size+" | "+file.type); var formdata = new FormData(); formdata.append("file1", file); 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", "file_upload_parser.php"); ajax.send(formdata); } function progressHandler(event){ _("loaded_n_total").innerHTML = "Uploaded "+event.loaded+" bytes of "+event.total; var percent = (event.loaded / event.total) * 100; _("progressBar").value = Math.round(percent); _("status").innerHTML = Math.round(percent)+"% uploaded... please wait"; } function completeHandler(event){ _("status").innerHTML = event.target.responseText; _("progressBar").value = 0; } function errorHandler(event){ _("status").innerHTML = "Upload Failed"; } function abortHandler(event){ _("status").innerHTML = "Upload Aborted"; } </script> </head> <body> <h2>HTML5 File Upload Progress Bar Tutorial</h2> <form enctype="multipart/form-data" method="post"> <input type="file"><br> <input type="button" value="Upload File"> <progress value="0" max="100"></progress> <h3></h3> <p></p> </form> </body> </html>

file_upload_parser.php：

<?php $fileName = $_FILES["file1"]["name"]; // The file name $fileTmpLoc = $_FILES["file1"]["tmp_name"]; // File in the PHP tmp folder $fileType = $_FILES["file1"]["type"]; // The type of file it is $fileSize = $_FILES["file1"]["size"]; // File size in bytes $fileErrorMsg = $_FILES["file1"]["error"]; // 0 for false... and 1 for true if (!$fileTmpLoc) { // if file not chosen echo "ERROR: Please browse for a file before clicking the upload button."; exit(); } if(move_uploaded_file($fileTmpLoc, "test_uploads/$fileName")){ echo "$fileName upload is complete"; } else { echo "move_uploaded_file function failed"; } ?>
