WP Max Submit Protect

Prevent large forms being submitted that may blow the server's field count limit and lose data.

Some appications, such as ecommerce sites, can have administration forms that submit well over a thousand parameters. PHP, by default, is set to accept only one thousand parameters and so some of the submitted data can get lost.

Most applications don't check whether they received everything, and so data can get broken easily and silently. A WooCommerce product with 40 variations can have over 1300 submitted form items, and when saving the product you have no idea that much of that data is being discarded.

Luckily the maximum number of accepted parameters can be changed in php.ini The problem is, many site owners have no idea this needs to be done until it is too late and their application, for example their WooCommerce store, has lost half its product variations.

To protect yourself and make sure the server limit does not catch you unawares, install this plugin and let it run in the background. Each time you try to submit a form in the admin pages (e.g. updating a WooCommerce product with lots of variatrions) this plugin will check that the number of form parameters you are about to submit does not exceed the server limit. If it does, then it will inform you and give you the opportunity to postpone the submit while you increase the server settings. The link above describes how to set the limits on the server. More details in the FQAs.

This plugin has been tested against PHP5.4 but is written to be compatible with PHP5.3. The project repository is here:
