Max_input_vars default value of 1000 in PHP causes multiple form submission failures

Reproduced in: http://54im.com/php-2/php-max-input-vars-default-value-1000-fail-post-form.html

A PHP management system in the company, before running in Apache, and later I transferred to the nginx+php, other functions run normally, there is a modification function submitted after the form did not submit success, checked the code did not find out what the problem, and then read the next PHP error log, There is no clue, after printing the post request, also found that the submission table single number and is not on the table single number pair (at that time suspected is not a plugin is not installed, the character set is right, etc.), and then looked at the next php-fpm log, a bit of information can be consulted.

The number of input variables is more than 1000, it is recommended to modify max_input_vars,php in the php.ini file to add a variable from 5.3.9 max_input_vars to limit the number of forms submitted.

Damn, I have this feature (similar to the Phpmysqladmin function, reading a database table, then writing to the editor, then the database field has 128, then each field has 11 input boxes) about 1400 more input, (how painful the understanding, for the hair so hanging, Develop a table to engage in so many fields),

And then I joined in PHP.ini.

123	max_execution_time = 300     ; maximum execution Time of each script, in seconds max_input_time = 0 ; Maximum amount of time each script may spend parsing request C20>data max_input_vars =

After restarting the PHP-FPM, the function is OK. It's important to look at the logs.
