WampServer

I have a PHP file that has a form that is supposed to be sending 1060 entries (from 1060 textboxes) to a PHP file which will then add them in a database. But from the 711th textbox to the 1060th, it doesn't retrieve anything and sends me the Undefined index SQL error. The 1060 textboxes basically has the same codes except for some numbers are changed. Is there a limit on the number of textboxes that can be retrieved? If there is a limit, is there a way to increase it? (I am using WAMP/I am not using the GETmethod, only POST)

Basically, from the 711th textbox to the 1060th, gets the Undefined Index error.

Hi,

Wampmanager->PHP->php.ini
Replace the value of

max_input_vars = 2500

or more

I am using Wamp 2.4, and I can't find 'max_input_vars' in it, can I just add it and where should I?

Yes, its a valid command to PHP, I assume that version of PHP just assumed the default and didnt have that param in the php.ini

|Find this section of your php.ini file

max_input_time = 60

; Maximum input variable nesting level
; [php.net]
;max_input_nesting_level = 64

and add it in there like this

max_input_time = 60

; Maximum input variable nesting level
; [php.net]
;max_input_nesting_level = 64

; How many GET/POST/COOKIE input variables may be accepted
max_input_vars = 2500

Still sending the Undefined index, I am printing all the variables in the '$_POST' method and after the 710th textbox, it is undefined. Does a browser also has this setting too? Maximum post values?

Did you edit the correct php.ini.

Use the wampmanager menus to make sure you edit the correct php.ini ( there are 2 )

So do

left click wampmanager icon -> PHP -> php.ini

The correct file is actually located in \wamp\bin\apache\apache2.x.y\bin\php.ini but use the wampmanager menus to edit it, its safer and more lkely to edit the right file.

Yes I did change it using that process. Can I send you a sample of my files for you to be able to personally see it?

Ok maybe the limitation is not just to the number of parameter but also the allowed size of the posted data.


Look at your php.ini again and check this

; Maximum size of POST data that PHP will accept.
; [php.net]
post_max_size = 8M

Change the value to something larger ( 16M ) and see if you get more variables available in $_POST, keep increasing until they are all available

It may also be a good idea to check for

memory_limit = 

and increase that a little, usually best to increase this in 4M blocks

Hi,

Documentation for max-input-vars

See php_error.log file to see what error or warning there is.

Hi Oto,

He claims he already changed that parameter, so I was just taking the next step and assuming that the Amount of data may have been exceeded as well as the number of allowed parameters.

Sorry to but in on your conversation.

Hi,

> Sorry to but in on your conversation.
There is not to be sorry. Our goal, both of us, is to help!
If there has "error_reporting = E_ALL" in php.ini, we'll know if it's a memory overflow or exceeding the number of variables. The documentation says it will have a "warning" if there is exceeding the number.

I had WAMP services restarted; did not fixed it. Restarting the PC solved it. Increasing max_input_vars, post_max_size, & memory_limit solved it. Thank you for directing me in the right idea/solution, it is awesome to experince this forums and be helped by people without 'downvoting' the question for technicalities/upvotes.

Been to stackexchange then I see. I didnt see your question over there.

Glad to be of help.
