In some cases, you will need to post a lot of variables. Under some circumstances, some server side or PHP settings will block you from sending too much variables over post data.
It is easy to overcome this. Just read on.
Determining the cause:
There are two ways PHP will block long and numerous post variables, suhosin security module and generic php.ini settings. In both the cases, you’d need to upload a file named phpinfo.php to your server with following code inside:
http://domain.com/phpinfo.php and search for (Simple Ctrl + F), suhosin. If you find something like
This server is protected with the Suhosin Patch 0.9.10
then your server has suhosin installed.
Otherwise, it is limited by generic php.ini settings.
Solutions:
Depending on the cause, the solution will vary. But both of them require editing your php.ini file. Check this tutorial to learn how to.
Increasing suhosin variable:
Edit the following variables and put the values as given below:
suhosin.request.max_vars = 2048 suhosin.request.max_value_length = 1000000 suhosin.request.max_array_index_length = 256 suhosin.request.max_totalname_length = 8192 suhosin.post.max_vars = 2048 suhosin.post.max_array_index_length = 256 suhosin.post.max_totalname_length = 8192 suhosin.post.max_value_length = 1000000 suhosin.sql.bailout_on_error = Off suhosin.log.file = 0 suhosin.log.phpscript = 0 suhosin.log.phpscript.is_safe = Off suhosin.log.sapi = 0 suhosin.log.script = 0 suhosin.log.use-x-forwarded-for = Off
If you do not have access to your php.ini file, then you can try doing it by adding the following code to the .htaccess file on the root of your server.
<IfModule mod_php5.c> php_value suhosin.request.max_vars 2048 php_value suhosin.request.max_value_length 1000000 php_value suhosin.request.max_array_index_length 256 php_value suhosin.request.max_totalname_length 8192 php_value suhosin.post.max_vars 2048 php_value suhosin.post.max_array_index_length 256 php_value suhosin.post.max_totalname_length 8192 php_value suhosin.post.max_value_length 1000000 php_flag suhosin.sql.bailout_on_error Off php_value suhosin.log.file 0 php_value suhosin.log.phpscript 0 php_flag suhosin.log.phpscript.is_safe Off php_value suhosin.log.sapi 0 php_value suhosin.log.script 0 php_flag suhosin.log.use-x-forwarded-for Off </IfModule>
Increasing generic php.ini value:
Edit the following variable and put the value as given below
max_input_vars = 20480 post_max_size = 32M
If all of the methods fail, then you’d need to ask your web host. Sometimes, these variables are also blocked by server side firewalls.
