I had a similar problem today. I had a form with 250+ rows and 5 variables per row, but the $_POST variable appeared to be truncated. In my case, it stopped after 1000 elements.

There is a PHP setting called max_input_vars that defaults to 1000. This setting sets an upper limit on how many variables it will pull into your PHP script. You may need to increase this value on your server settings to make your page work. There are some security implications that I don't fully understand with increasing this value that could enable a denial of service attack.

Since you are developing a Wordpress plugin, you may need to see if there are ways to change your form to reduce the number of variables you send, because you probably can't alter server configurations for people using your plugin.
