+--- Thread: getVar() behavior on Windows and Linux (/showthread.php?tid=85987)
getVar() behavior on Windows and Linux - ruslan - 12-29-2022
$this->request->getVar("id") in a controller works for GET request parameters only on my local env - Windows 10 / Apache / PHP8
On Ubuntu 20 / Nginx / PHP8 i get `undefined` for the same request
Replacing it with getGet("id") solves the problem
PHP Code:
return $this->respond([
"id-get" => $this->request->getGet("id"),
"id-var" => $this->request->getVar("id"),
"GET" => $_GET
]);
Response:
Code:
GET: {id: "1", data: "{"status":"0"}"}
id-get: "1"
id-var: nullIsn't it a bug? Because documentation says: "The getVar() method will pull from $_REQUEST, so will return any data from $_GET, $POST, or $_COOKIE (depending on php.ini request-order)."

Check the request_order value in phpinfo().
If G is not set, GET values are not set in $_REQUEST.

request_order GP
RE: getVar() behavior on Windows and Linux - kenjis - 12-29-2022
Okay, no problem.
I don't know why you can't get with getVar().
Did you checked the $_REQUEST value?
RE: getVar() behavior on Windows and Linux - ruslan - 12-29-2022
$_REUEST is empty
Code:
"id-get": "22",
"id-var": null,
"GET": {
"id": "22"
},
"REQUEST": [],I guess the documentation should say that not only `request_order` affects getVar()/$_REQUEST content

Quote:request_order string
This directive describes the order in which PHP registers GET, POST and Cookie variables into the _REQUEST array. Registration is done from left to right, newer values override older values.
If this directive is not set, variables_order is used for $_REQUEST contents.
https://www.php.net/manual/en/ini.core.php#ini.request-order
Your $_REQUEST should have GET and POST values.
This is not CodeIgniter matter, but PHP matter.
It is very wired that your $_REQUEST is an empty array.

It is a default Ubuntu 20 / Nginx / PHP-FHM 8.1 setup
No customization
I agree that it is not a CI issue, but better to warn users that getVar/REQUEST depends not only on `request_order`

No, i don't want my code to depend on any server environment
I will use getGet() for GET requests
RE: getVar() behavior on Windows and Linux - kenjis - 12-30-2022
Okay, no problem.
I think it is better not to use getVar(), because if you use it, you don't know the value where comes from exactly.
It might cause security issues, although I do not believe the risk is high.
