When you click on this container an open file window will open and you can select any file to upload. Once you select the file then you can see in the second picture, there is shown your file uploading status with filename, uploaded percent, progress bar, etc. and there is the history of the uploaded files with filename, size, etc.

I hope you want to get source codes or files of this project but don’t worry I have given all to source codes to the bottom of the page. But before copy-paste the codes, let’s talk about the important codes and concepts behind creating this file uploader.

In the JavaScript file, I used the change event to get the user selected filename and then called the uploadFile(filename) function with passing the filename as an argument. Inside uploadFile() function, using Ajax I sent the selected file to the PHP. As you can have seen on the codes, I used upload property and progress event to get file loaded value and file total size.

In the PHP file, I received the file and added the current time before the filename to make the filename dynamic and moved this file to the files folder using PHP inbuilt function move_uploaded_file.

fileInput = document.querySelector(".file-input"),
progressArea = document.querySelector(".progress-area"),

form.addEventListener("click", () =>{
  fileInput.click();
});

fileInput.onchange = ({target})=>{
  let file = target.files[0];
  if(file){
    let fileName = file.name;
    if(fileName.length >= 12){
      let splitName = fileName.split('.');
      fileName = splitName[0].substring(0, 13) + "... ." + splitName[1];
    }
    uploadFile(fileName);
  }
}

function uploadFile(name){
  let xhr = new XMLHttpRequest();
  xhr.open("POST", "php/upload.php");
  xhr.upload.addEventListener("progress", ({loaded, total}) =>{
    let fileLoaded = Math.floor((loaded / total) * 100);
    let fileTotal = Math.floor(total / 1000);
    let fileSize;
    (fileTotal < 1024) ? fileSize = fileTotal + " KB" : fileSize = (loaded / (1024*1024)).toFixed(2) + " MB";
    let progressHTML = `<li class="row">
                          <i class="fas fa-file-alt"></i>
                          <div class="content">
                            <div class="details">

                        </li>`;
    uploadedArea.classList.add("onprogress");
    progressArea.innerHTML = progressHTML;
    if(loaded == total){
      progressArea.innerHTML = "";
      let uploadedHTML = `<li class="row">
                            <div class="content upload">
                              <i class="fas fa-file-alt"></i>
                              <div class="details">
