Loading main page (not logged in) generate unnecessary request to github/slows everything down

[JabLuszko]

As titles states - loading main page as not logged in can be very slow - depending how fast GitHub answers 404 ;')

index.php includes header.php that includes functions.php that includes cache_handler.php and that one tries to load pokemonNames/itemNames. Only problem is both local and remote uses $locale as part of path and because $locale is empty it's testing non-existing files and then trying to download non-existed files (fe. fopen(https://raw.githubusercontent.com/WatWowMap/pogo-translations/master/static/englishRef/pokemon_.json): Failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found)

$locale is get via session $locale = @$_SESSION['locale']; and set in set_locale()

PoracleWeb/include/functions.php

Lines 316 to 331 in ed58d43

	function set_locale() {
	global $conn;
	if (isset($_SESSION['id'])) {
	include_once "./config.php";
	include_once "./include/db_connect.php";
	$sql = "select language FROM humans WHERE id = '" . $_SESSION['id'] . "'";
	$result = $conn->query($sql) or die(mysqli_error($conn));
	while ($row = $result->fetch_assoc()) {
	if ( $row['language'] <> "" ) {
	$_SESSION['locale'] = $row['language'];
	} else {
	$_SESSION['locale'] = $_SESSION['server_locale'];
	}
	}
	}
	}

but only if $_SESSION['id'] exists - so not logged in users will have no locales at all.

Possible solutions:
Set $_SESSION['locale'] for not logged in users as default (?) one?
Force $locale as "en" if empty in cache_handler.php?
Don't include cache_handler.php at all if user not logged in - is there anything need to render main login page?

Are there other parts of code depending on not set at all $_SESSION['locale']?

Just added a default session locale for all users, should solve it...
