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

Note that you must put this in the file   user ini  in Centos7 rather than  php ini  which used to work in Centos6   You can put   user ini  in any subdirectory in order to affect only that directory    user ini    max input vars   3000   Tested on Centos7 and PHP 5 6 33

Just to complement  On a shared server using mod suphp I was having the same issue   Declaring 4 max input vars  suhosin included   didn t solved it  it just kept truncating on 1000 vars  default   and declaring  php value max input vars 6000  on  htaccess threw error 500   What solved it was to add the following on  htaccess  which applies the php ini file recursively to that path  suPHP ConfigPath  home myuser public html

Have just attempted this fix with 5 3 3 and there s no change  Googling around I found this web page http   anothersysadmin wordpress com 2012 02 16 php-5-3-max input vars-and-big-forms  detailing other settings which need changing if your server uses the Suhosin patch which Apache under Debian does   The site explains      So  if you want to increase this number to  say  3000 from the default   number which is 1000  you have to put in your php ini these lines       max input vars   3000   suhosin post max vars   3000   suhosin request max vars   3000   I tested it  added settings to php ini both in  etc php5 apache2 and  etc php5 cli  and restarted Apache successfully  but still no max input vars variable in phpinfo   A few sites point to PHP 5 3 9 as the first PHP version in which this change will take  so my fault for not RTM properly in the first place  although I m interested to see people reporting it working in version above 5 3 3 but below 5 3 9

New Cpanels block to see the  htaccess file or if you add a  user ini you wont be able to see it  but with a little hack you can make it work  Edit for example wp-config php and in the URL bar replace wp-config php by  htaccess  now you can paste the values and save it   enter image description here

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

You can add it to php ini and it should work - just tested it on PHP 5 3 6

Use of this directive mitigates the possibility of denial of service attacks which use hash collisions  If there are more input variables than specified by this directive  an E WARNING is issued  and further input variables are truncated from the request   I can suggest not to extend the default value which is 1000 and extend the application functionality by serialising the request or send the request by blocks  Otherwise  you can extend this to configuration needed   It definitely needs to set up in the php ini
