The Problem:
If you are using web applications such as magento, it is common that you encounter error like below:
Warning: your hosting provider limits the maximum number of fields to post in a form: 1000 for max_input_var

The Solution:
By default the max_input_var will be 1000, this is some kind of security prevention from the PHP module.
Therefore if your application would require higher number of max_input_var, you can increase the defined value higher than the requirement by adding the below line into the .htaccess file in the web files main page directory.
php_flag max_input_var 1234
Replacing 1234′ with the value you want to set
