Quote:Destroys the global GET array. Since CodeIgniter does not utilize GET strings, there is no reason to allow it.
Found this is the user guide under http://ellislab.com/codeigniter/user-guide/libraries/input.html; further down on the page they provide methods to grab GET data. My question is, can I access a GET string?
Thank you!

yes CI cleans the GET global but it leaves the SERVER['QUERY_STRING'] alone so all you have to do is
Code:
$_GET = parse_str($_SERVER['QUERY_STRING']);And then you can even use the CI uri methods afterwards.

So it will take:
Code:
?Type=whatever&people=modelAnd place into that into Server query string? Any idea if there are string size limitations to this?
I am working with an old scripting system and they are transferring data using GET quite a bit. Will try to get away from soon.
Thanks

yes but you can't use the auto uri_protocol because this will try to process the query string in certain circumstances.

I can't auto-load the uri library if i'm trying to access the get string?

The URI library is loaded by default.

Well, that server variable is available whether or not you use CI. xwero just shows you how to repopulate the $_GET superglobal by parsing this environment variable.

Colin thank you for putting my code snippet into context.
The SERVER query_string is generated by the sever upon the request that has been received, just like GET but that global puts the query_string in an easier to use array. The parse_str function is like a specialised explode function because it will break the query string like you are used to receive GET and POST input.
Oops the use of the parse_str function is wrong, it has to be
Code:
parse_str($_SERVER['QUERY_STRING'],$_GET);INPUT CLASS destroys global get? - El Forum - 04-10-2009

Here is my solution to the occasional need to acquire a querystring parameter value from a GET request.
Note: $config['enable_query_strings'] = FALSE; in my config.php
Code:
/**
*url querystring parameter
*ADDED to CI url_helper.php by Kevin Davis 4/10/09
*retrieve a querystring value from a GET request
*
*Location: ./system/helpers/url_helper.php
*
*@access public
*@param string
*@return string
*/
if ( ! function_exists('querystring_get_param_value'))
{
function querystring_get_param_value($key)
{
//This codeblock acquires a querystring value from the $_SERVER array.
preg_match("/[?&]" . $key . "=([^&$]*)/", $_SERVER['REQUEST_URI'], $matches);
if(count($matches) == 2){
$value = urldecode($matches[1]);
}
else{
$value = '';
}
return $phrase;
}
}
//after adding this function to url_helper.php you can simply do the following
$value = querystring_get_param_value('txt');
//$value will equal 'foo' for something like example.com/sample?txt=foo
//Hope someone finds this useful.INPUT CLASS destroys global get? - El Forum - 04-10-2009

judico doing a preg_match for every value you have to get is more expensive than parsing the query string once and putting it in a variable, it doesn't have to be the get global.
