PHP AJAX Image Upload

Hello Guys Welcome to Coding Gurus Online Portal ...!

In this tutorial let us learn about how to upload an image file using PHP and AJAX. We are using jQuery AJAX to send image file to the server side PHP script.

Steps for PHP AJAX Image Upload

  1. 1. Add jQuery library
  2. 2. Create HTML for image upload form
  3. 3. Send file data to PHP via AJAX
  4. 4. Write PHP script to upload image

PHP Example to Upload Image

HTML code for the form containing file input is,

<form id="uploadForm" action="upload.php" method="post">
Upload Image File:
<input name="userImage" type="file" class="inputFile" />
<input type="submit" value="Submit" class="btnSubmit" />

On submit, the AJAX call will be triggered to send form's file input to the PHP page upload.php. The script is,

$(document).ready(function (e){
url: "upload.php",
type: "POST",
data: new FormData(this),
contentType: false,
cache: false,
success: function(data){
error: function(){}
