How to Change the Timeout on the Modern File Upload


Would you like to change the timeout when uploading files through the Modern File Upload form field? This can be particularly helpful when you are expecting large files to be uploaded through your form.

By default, the timeout set on the Modern File Upload field is set to 30 seconds or 30000 milliseconds, with a small PHP snippet you can easily change this timeout to be whatever you’d like.


All you need to do is add this snippet to your site.

If you’re not sure where or how to add snippets to your site, please take a look at this tutorial.

In our example, we’re changing the timeout from 30000 milliseconds (30 seconds) to 60000 milliseconds (60 seconds).

 * Change the timeout on the modern file upload from 30 to 60 seconds.
 * @link

function wpf_dev_modern_file_upload_timeout() {
	<script type="text/javascript">
		window.addEventListener( 'load', function() {
			if ( typeof wpforms.dropzones === 'undefined' )  {
			wpforms.dropzones.forEach(function( dropzone ) {
				dropzone.options.timeout = 60000; // The timeout for the XHR requests in milliseconds.
		} );
add_action( 'wpforms_wp_footer', 'wpf_dev_modern_file_upload_timeout', 30 );

You’ll just need to set the 60000 to what you would like.

Please note that just by changing this number, this doesn’t mean that your hosting company won’t also have a global cap set on your timeout functions, also known as PHP max_execution_time. You’ll need to reach out to your hosting company to increase this on your server if you have the need to increase this amount as well.

And that’s it! You’ve successfully increased the timeout from 30 seconds (30000 milliseconds) to 60 seconds (60000 milliseconds).
