How to detect that JavaScript and/or Cookies are disabled? - Flavius Popa - 2013-12-06
Hello,
Is there any plugin for MyBB to detect if javascript and/or cookies are disabled, without refreshing the page ?
I tried to make one, it works for javascript but I'm not sure if is safe to create a hidden form and submit it with javascript and see if is enabled or not.
Also, is any method in MyBB to create a custom cookie?
I used '$_COOKIE["js"]' but again... I think there is a better way to do this.
<?php
// access denied
if(!defined("IN_MYBB"))
{
die("Direct initialization of this file is not allowed.");
}
// hook
$plugins->add_hook("pre_output_page", "checkjs");
// info
function checkjs_info()
{
return array(
"name" => "Check Javascript",
"description" => "A sample plugin that check if javascript is disabled",
"website" => "http://mybb.com",
"author" => "",
"authorsite" => "",
"version" => "0.1",
"guid" => "",
"compatibility" => "16*"
);
}
// checkjs
function checkjs($page)
{
if(isset($_COOKIE["js"]) && isset($_COOKIE["sid"]) && $_COOKIE["js"] == $_COOKIE["sid"])
{
return $page;
}
if(isset($_POST['jstest']))
{
if(isset($_COOKIE["sid"]))
{
setcookie("js", $_COOKIE["sid"]);
}
// JS is enabled
$nojs = FALSE;
}
else
{
// create a hidden form (and submit it with javascript)
echo '<form name="jsform" id="jsform" method="post" style="display:none">';
echo '<input name="jstest" type="text" value="true" />';
echo '<script language="javascript">';
echo 'document.jsform.submit();';
echo '</script>';
echo '</form>';
// JS is disabled
$nojs = TRUE;
}
if($nojs)
{
$replace = '<p>Javascript is disabled!</p><div id="content" style="display:none">';
$page = str_replace('<div id="content">', $replace, $page);
}
return $page;
}
?>
I appreciate any help.
