PHP max_input_vars

Question

I'm getting a max_input_vars error message.

I understand there's a php.ini setting that can change this starting with version 5.3.9 however, I'm running version 5.1.6.

When I view the configuration information for my 5.1.6 server it shows max_input_vars value is 1000.

My question is: Even though I'm running 5.1.6, I see this setting from phpinfo() but it's not in the php.ini file. Does this mean that the value is hard coded in this version of PHP and can't be changed?

Answer 1

Reference on PHP net:

http://php.net/manual/en/info.configuration.php#ini.max-input-vars

Please note, you cannot set this directive in run-time with function ini_set(name, newValue), e.g.

ini_set('max_input_vars', 3000); 

It will not work.

As explained in documentation, this directive may only be set per directory scope, which means via .htaccess file, httpd.conf or .user.ini (since PHP 5.3).

See http://php.net/manual/en/configuration.changes.modes.php

Adding the directive into php.ini or placing following lines into .htaccess will work:

php_value max_input_vars 3000 php_value suhosin.get.max_vars 3000 php_value suhosin.post.max_vars 3000 php_value suhosin.request.max_vars 3000 

Answer 2

You can add it to php.ini and it should work - just tested it on PHP 5.3.6.
