Introduction

PHP POST max size defines the maximum amount of data that can be submitted through POST requests, and adjusting this limit is essential for handling large form submissions and file uploads. Applications requiring large file uploads, multiple simultaneous file submissions, or extensive form data may exceed default POST size limits, causing submission failures or incomplete data processing. DirectAdmin’s PHP Settings interface provides a straightforward method for configuring POST data size limits through custom PHP overrides. This guide explains how to modify POST max size using the PHP Settings section in DirectAdmin, ensuring your applications can accept appropriately sized data submissions without errors.

Prerequisites

Access to DirectAdmin control panel with the necessary permissions.

Step-by-step Guide

Step 1: Access DirectAdmin

Step 2: Access PHP Settings

Go to the Your Account section and click on Domain Setup. Then, select the domain/subdomain you wish to modify PHP settings for by clicking on the domain/subdomain name.

At the PHP Access row, click Php Settings…. You should be able to see a list of your current PHP configuration.

Step 3: Modify Maximum POST data size

Scroll down to the Add Override section. On the post_max_size row, you may select the maximum size of POST data that you wish PHP will accept.

Then, click Save on the right.

Tips 🖊️: If you are trying to upload multiple files at once, the post_max_size must be large enough to hold the combined sum of all those files plus any form text data.

Step 4: Verify the changes

You may confirm the new override settings in the updated Domain php.ini overrides table.

Conclusion

Configuring PHP POST max size through DirectAdmin’s PHP Settings interface is a simple process that controls the maximum amount of data accepted in POST requests. Adjusting this limit enables your applications to handle large file uploads and extensive form submissions, with sufficient capacity to accommodate multiple files and form data within a single request.
