After integrating fine-uploader script into a new code igniter installation, I have the following problem: IE 9 returns false when using the "if (!$this->input->is_ajax_request())" command.
class Welcome extends CI_Controller {
public function index()
{
$this->load->view('upload');
}
public function upload()
{
error_reporting(E_ALL | E_STRICT);
if (!$this->input->is_ajax_request())
{
die('No direct script access allowed');
}
$this->load->helper("qqFileUploader.class");
$uploader = new qqFileUploader('uploads');
// Specify the list of valid extensions, ex. array("jpeg", "xml", "bmp")
$uploader->allowedExtensions = array();
// Specify max file size in bytes.
$uploader->sizeLimit = 900 * 1024 * 1024; // 900 Megabytes
// Specify the input name set in the javascript.
$uploader->inputName = 'qqfile';
$uploader->prefix = 'test_';
// If you want to use resume feature for uploader, specify the folder to save parts.
$uploader->chunksFolder = 'chunks';
$result = $uploader->handleUpload('uploads');
$result['uploadName'] = $uploader->getUploadName();
header("Content-Type: text/plain");
echo json_encode($result);
}
}
Why?
This is completely expected. Fine Uploader does not use XHR to upload files in IE 9 and older (since this is not possible). Instead, we build a form and submit it, targeting an iframe.

if caching is turned off then everything works correctly. if you enable caching, the plugin at the beginning works correctly, but after 5 minutes it stops processing the line. normal or progressive caching — it doesn’t matter. when you delete the cache — processing is turned on again, and again after 5 minutes it disappears.
here is the complete plugin code. what could be the reason?
code inserted into the material for example such {robokassa 5}
class plgContentRobokassa extends JPlugin
{
public $cont='';
public function onContentPrepare($context, &$row, &$params, $page = 0)
{
$doc = JFactory::getDocument();
$doc->addStyleSheet(JURI::root(true).'/plugins/content/robokassa/css/robokassa.css');
$this->cont=$context;
}
public function onAfterRender()
{
$is_test='0';
$mrh_pass1='*****';
$mrh_login='******';
$app = JFactory::getApplication();
if ($app->getName() != 'site') {
return true;
}
// Получаем кодовое слово из параметров
$varname = 'robokassa';
//Получаем тело сайта
$html = $app->getBody();
// Если тегов нет
if (strpos($html, $varname) === false)
{
return true;
}
$bodyPos = stripos($html, '<body');
$preContent = '';
if ($bodyPos > -1)
{
$preContent = substr($html, 0, $bodyPos);
$html = substr($html, $bodyPos);
}
//Задаем шаблон поиска
$pattern = '#\{' . $varname . ' ([0-9]+)\}#i';
//Закидываем все найденные шаблоны в массив
if (preg_match_all($pattern, $html, $matches))
{
$db = JFactory::getDbo();
$query = $db->getQuery(true);
foreach ($matches[0] as $i => $match)
{
*replace code here*
}
$html=$preContent.$html.$script_alert;
//Запихиваем всё обратно в тело
$app->setBody($html);
}
}
}
The plugin events are invoked in the order they have in the Plugin administration.
Cache is part of the System plugins so when their cache is valid the response is retrieved from Cache, and the plugins which come before it are not executed.
You could be able to solve this by moving your plugin after Cache (or last)
If the plugin is of a different kind, i.e. Content, there is no way to achieve this.
You can change it into a System plugin (all events from any plugin category is available also in the System plugins).
Another alternative, you could put your code in a module, prevent caching in the module; but this will not work with page cache.
Finally, and I don't know why I didn't write it first, make an Ajax call to a page which you will NOT cache (by excluding it in the page cache plugin configuration: that way the page will be cached and each time it will retrieve the current data.
I am trying to get a cache working in my plugin.
In ext_localconf.php
if (!is_array($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension'])) {
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension'] = [];}
if (!isset($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['frontend'])) {
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['frontend'] = 'TYPO3\\CMS\\Core\\Cache\\Frontend\\StringFrontend';}
if (!isset($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['options'])) {
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['options'] = ['defaultLifetime' => 0];}
if (!isset($GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['groups'])) {
$GLOBALS['TYPO3_CONF_VARS']['SYS']['caching']['cacheConfigurations']['myextension']['groups'] = ['pages'];}
In my controller action :
$cacheIdentifier = 'topic' . $topic->getUid();
$cache = GeneralUtility::makeInstance(CacheManager::class)->getCache('myextension');
$result = unserialize($cache->get($cacheIdentifier));
if ($result !== false ) {
DebuggerUtility::var_dump($result);
} else {
$result = $this->postRepository->findByTopic($topic->getUid(), $page, $itemsPerPage);
$cache->set($cacheIdentifier, serialize($result), ['tag1', 'tag2']);
DebuggerUtility::var_dump($result);
}
The first time the page with the action gets loaded all is ok and the entry has been made in de database (cf_myextension and cf_myextension_tags}.
But the 2nd time the cache gets loaded and I get an error. Even DebuggerUtility::var_dump($result); does not work:

/**
A normal var_dump works and spits out the cache entry. What is the problem? Do I forget something? Can't a QueryResult together with some other variables not be stored as an array in the cache? I also tried VariableFrontend cache, which produced the same error.

I'm using Laravel 4 with dompdf package: https://github.com/barryvdh/laravel-dompdf
When I generate a report and it converts it to PDF on my local, everything is fine and displays well, but when I do the same exact thing on my production server, it displays random letters where there is either dynamic or static content.
Screenshot of local vs production:

Everything writes fine and it uses the right template and has the styling... Only the static content and dynamic content (values written out with PHP variables) display badly, although you can see some of the static content like Energy Savings and such prints fine.
Is there a reason this could be all jumbled up on the live server, but not local?
Here is the HTML for the view that is being grabbed (the HTML the php variables are injected into): http://pastebin.com/5bMR6G2s
And here is my config file for dompdf:
http://pastebin.com/Ld6MQckG
There are two possible causes for this:
Missing font(s) on the production server. Make sure you have the correct fonts installed on the production site.
Character encoding issues. I'm not sure which site (dev/live) the issue is on, but it may be that one is outputting UTF-8 and the other is not. You could try to sort this out by detecting the encoding on the input file on both dev and live by using mb_detect_encoding and see if they're different. If they are, then use mb_convert_encoding before converting to PDF.
I am working on the log in system for a site using Flexi Auth in Codeigniter V 2.1.4. I am trying to pass a user's log in status to a menu that changes dynamically depending whether a user is logged in or not. This is the code i am using:
public function create_page($pgName = 'home')
{
$this->config->load('tera_site', TRUE);
$this->load->library('flexi_auth_lite');
// Cunstruct Page data
$data['pgName'] = $pgName;
if ($this->session->userdata('admin') === FALSE){$data['admin'] = 0;}else{$data['admin'] = $this->session->userdata('admin');}
$data['siteTitle'] = $this->config->item('siteTitle','tera_site');
// This is the line the Error is thrown from:
$data['loggedIn'] = $this->flexi_auth_lite->is_logged_in();
$data['header'] = $this->load->view('include/header', $data, TRUE);
$data['pages'] = $this->config->item('pages','tera_site');
$data['footer'] = $this->load->view('include/footer', False, TRUE);
$data['sideBar'] = $this->load->view('include/side_bar_view', $data, TRUE);
$this->load->model('page_model');
$data['pgData'] = $this->page_model->getPage($pgName);
// load the Catcha Library
$this->load->library('captcha_my');
if($data['pgData']['Captcha'] = 1) {
$data['Captcha'] = $this->captcha_my->createCaptcha();
} else if ($this->session->userdata('captchaCheck') == true) {
$data['Captcha'] = $this->captcha_my->createCaptcha();
}
return $data;
This is the error:
Severity: Notice
Message: Undefined property: Main::$flexi_auth_lite
Fatal error: Call to a member function is_logged_in() on a non-object
The code worked at one time, but even when it did it threw the same error when i called the function is_admen() from flexi_auth. Flexi_auth.php and Flexi_auth_lite.php are in application/libraries directory.
if you look into the demo files, there is a controller 'auth_lite.php'
it says
// IMPORTANT! This global must be defined BEFORE the flexi auth library is loaded!
// It is used as a global that is accessible via both models and both libraries, without it, flexi auth will not work.
$this->auth = new stdClass;
// Load 'lite' flexi auth library by default.
// If preferable, functions from this library can be referenced using 'flexi_auth' as done below.
// This prevents needing to reference 'flexi_auth_lite' in some files, and 'flexi_auth' in others, everything can be referenced by 'flexi_auth'.
$this->load->library('flexi_auth_lite', FALSE, 'flexi_auth');
I am trying to get the new PDO driver running in Code Igniter 2.1.1 in (to start with) the local (Mac OS 10.7) copy of my app.
I initially coded it using Active Record for all db operations, and I am now thinking I want to use PDO prepared statements in my model files, going forward.
I modified 'application/config/database.php' like so:
(note a couple minor embedded questions)
[snip]
$active_group = 'local_dev';
$active_record = TRUE;//<---BTW, will this need to stay TRUE to make CI sessions work? For better security, don't we want db-based CI sessions to use PDO too?
//http://codeigniter.com/user_guide/database/configuration.html:
//Note: that some CodeIgniter classes such as Sessions require Active Records be enabled to access certain functionality.
//this is the config setting that I am guessing (?) is my main problem:
$db['local_dev']['hostname'] = 'localhost:/tmp/mysql.sock';
// 1.) if $db['local_dev']['dbdriver']='mysql', then here ^^^ 'localhost:/tmp/mysql.sock' works, 2.) but if $db['local_dev']['dbdriver']='pdo', then it fails with error msg. shown below.
$db['local_dev']['username'] = 'root';
$db['local_dev']['password'] = '';
$db['local_dev']['database'] = 'mydbname';
$db['local_dev']['dbdriver'] = 'pdo';
$db['local_dev']['dbprefix'] = '';
$db['local_dev']['pconnect'] = TRUE;
$db['local_dev']['db_debug'] = TRUE;//TRUE
$db['local_dev']['cache_on'] = FALSE;
$db['local_dev']['cachedir'] = '';
$db['local_dev']['char_set'] = 'utf8';
$db['local_dev']['dbcollat'] = 'utf8_general_ci';
$db['local_dev']['swap_pre'] = '';
$db['local_dev']['autoinit'] = TRUE;
$db['local_dev']['stricton'] = FALSE;
[snip]
With the above config., as soon as I load a controller, I get this error message:
Fatal error: Uncaught exception 'PDOException' with message 'could not find driver' in
/Library/WebServer/Documents/system/database/drivers/pdo/pdo_driver.php:114 Stack trace: #0

I tried swapping out the 'pdo_driver.php' file from the one on github, as per this:
http://codeigniter.com/forums/viewthread/206124/
...but that just generates other errors, not to mention is disturbing to a newbie who does not want to touch the system files if at all possible.
This thread also seems to imply the need to be hacking the 'pdo_driver.php' system file:
CodeIgniter PDO database driver not working
It seems odd to me, though, that (someone thought that) a hack to a system file is needed to make PDO work in CI v.2.1.1, huh?
Thanks for any suggestions I can try.
I don't know if this might be helpful for you since you already started using the CI functions, but I made my own library for PDO with sqlite and just auto load it. My needs were simple, so it serves its purpose.

thanks to the noob thread http://codeigniter.com/forums/viewthread/180277/ (InsiteFX’s answer)..
