This tutorial will helps you to understand about the form submission with a file. This article is for jQuery ajax file upload with form data using PHP. There are very few simple steps to do and complete this task.
To do for the article –

Let’s get started.
Application Files Setup
Create a folder with name like ajax-form. Inside this folder create two files. Create a users folder inside project folder. In this folder we will store user images. Folder should have proper permissions for read and write.
- student-form.php [ It will contain a form with file button ]

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.19.2/jquery.validate.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
<script>
// Custom code
$(function() {
// Adding validation
$("#student-form").validate();
$(document).on("submit", "form#student-form", function(e) {
e.preventDefault(); // prevent from default action
var formData = new FormData(this);
$.ajax({
url: $(this).attr('action'),
type: $(this).attr('method'),
cache: false,
data: formData,
processData: false,
contentType: false,
success: function(data) {
console.log(data);
}
});
});
});
</script>
</body>
</html>- jQuery validation plugin used inside above code for client side validation.
- $(“#student-form”).validate();
- var formData = new FormData(this); Get all form data
- Form will be submitted to ajax-handler.php, when ajax processes
- processData: false, contentType: false, This is very important to add. We will understand while application testing it.
Create Ajax Handler
Open ajax-handler.php and write this code into it.
Currently, inside ajax-handler file we don’t have any code like save to database, image upload to folder etc. but you can add those code too into it.
<?php
$user = $_FILES['image'];
if (isset($user)) {
$filename = $user['name'];
$tmp_path = $user['tmp_name'];
if (move_uploaded_file($tmp_path, "./users/" . $filename)) {
// You can write code to save into database
// You can write code to upload image into folder
echo json_encode(array(
"status" => 1,
"data" => $_POST,
"files" => $_FILES
));
} else {
echo json_encode(array(
"status" => 0,
"message" => "Failed to upload image"
));
}
}
- Accepting all input values via $_POST
- Get submitted files via $_FILES
Application Testing
Open project into browser.
URL: http://localhost/ajax-form/student-form.php
Submit form without any input values, we will get form validation error messages.
When we upload input values with a file.
Note*: If we forgot to add these properties into ajax request method of jquery, then you will get this error may be in your console. Add these.
processData: false, contentType: false,
Submit form with all valid values and adding jquery method properties, Now
