I am using this link to use the cookies functionality in yii framework.
When I accessed the application in localhost it gives following error:
Property CWebApplication.Cookies is not defined.
Please help me guys that where I am doing mistake.
I have included
'Cookies' => array (
'class' => 'application.components.CookiesHelper'
),
in config->main.php and i am trying to use the function putCMsg
as follows
$this->putCMsg('someCookieName','SomeValue');
But this error comes on this line of index.php
Yii::createWebApplication($config)->run();
Creating cookie in config/main.php is not a good solution. It's better to set cookie in the controller's action like this:
$cookie = new CHttpCookie('someCookieName','SomeValue');
$cookie->expire = 200000; //times in milliseconds
Hey everyone I'm following a tutorial on Composer, I've installed ActiveRecord and I'm trying to create a database model. Whenever I load the page though I get this error: Call to undefined method ActiveRecord\Config::initialise()
Here's my setup file in index.php
require_once "vendor/php-activerecord/php-activerecord/ActiveRecord.php";
ActiveRecord\Config::initialise(function($cfg) {
//setting up a model (which is the representation of a table)
$cfg->set_model_directory('models');
$cfg->set_connections(array(
'development' => 'mysql://root:tutsplus#localhost/blog'
));
});
$posts = Post::all();
print_r($posts);
?>
And here's where I declare Post
class Post extends ActiveRecord\Model{}
I really cannot find the reason this isn't working, I actually did this instead to see if manually creating a new Post instance would fix the initialisation problem but it didn't, it had exactly the same error:
$post_class = new Post;
$posts = $post_class->all();
print_r($posts);
I'm really stumped on this one, I've usually managed to find something that fixes my problem on here but this is just nope. There is literally no difference to the tutorial code that I can see and I've checked it loads of times. Any help would be greatly appreciated.
(edit: the duplicate php-activerecord folders at the top isn't a code problem, the folder is actually duplicated and I haven't got round to moving the contents yet)
Point one: When using Composer, you are supposed to only include "vendor/autoload.php", and nothing else. Composer does the rest of autoloading for you.
Point two: It is called initialize with a Z, not S. You might simply have misspelled that method name.
In my codeigniter i created a library in library folder.I want to load view pages in that library.How can i do this?
This is my code:
$this->load->view('view_page');
But when iam using this code i get an error:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: CI_theme_lib::$load
Filename: libraries/theme_lib.php
Line Number: 9
What is the problem in mycode?
In Line number 9 in library the code is :
$this->load->view('view_page');
To do what you're trying to do you need to get an instance of CI, and use that.
e.g.
$CI =& get_instance();
Within your library functions you could then use this variable to load the view:
$CI->load->view('view_page');
I would question though why you want to call a view, in the form that you have done, within a library. I suspect that you would be better to get the view call to return data (setting the 3rd parameter 'true') and then have your library return the display data to the controller.... Your approach seems messy, but then I have no idea what your library is trying to do.....
I have came across your question for different reason, I seem to have problem passing variables to views instead. Let me explain before I tell you answer to your problem.
Imagine you have an Emailer library to send emails rather than sorting that out in controller.
Emailer than within itself builds email string using views. My problem is that when I make my call from controller something like Emailer::send_mail($data,$template) it passes the variables correctly but when I do it from another library the view fails to register the variables. LOL
So yes Stéphane Bourzeix you do sometimes want to use output from view in a different way than just returning to client browser.
The solution is here.
https://www.codeigniter.com/userguide2/general/views.html
the last section of that page has something like
$string = $this->load->view('myfile', '', true);
but something like
$string = $this->load->view('myfile', $view_data, true);
should work too
in case of doing this from other places than controllers you will need to:
$this->ci = & get_instance();
$string = $this->ci->load->view("myfile",$view_data,true);
it seems like the last argument in the list (true) is the one that tells it not to render to browser but instead just create string with template content
I know it's a bit too late but hope it still helps to some. Good luck with your code.

You simply DON'T load pages (aka Views) in a Library.
I don't see any need for doing this.
We're randomly getting some very strange error logs. They don't happen on every page hit, even with the same parameters/actions/etc, and they don't seem repeatable, each one is different in its crash location, and context. But almost all have incorrect __PHP_Incomplete_Class_Name as the cause.
One such error is:
main(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "LoginLogging" of the object you are trying to operate on was loaded before unserialize() gets called or provide a __autoload() function to load the class definition
The problem being, there is no "LoginLogging" class. The object it's referring to was of type ScormElement when it was saved into the session.
Doing a dump of the variable gives:
__PHP_Incomplete_Class::__set_state(array(
'__PHP_Incomplete_Class_Name' => 'LoginLogging',
'intUserId' => '64576',
'__intUserId' => '64576',
'intScormId' => '665',
'__intScormId' => '665',
'intScoId' => '9255',
'__intScoId' => '9255',
'strElement' => 'cmi.core.lesson_location',
'__strElement' => 'cmi.core.lesson_location',
'strValue' => '1',
'dttTimeModified' => QDateTime::__set_state(array(
'blnDateNull' => false,
'blnTimeNull' => false,
'strSerializedData' => '2011-08-31T08:05:22-0600',
'date' => '2011-08-31 08:05:22',
'timezone_type' => 1,
'timezone' => '-06:00',
)),
'__strVirtualAttributeArray' => array (),
'__blnRestored' => true,
'objUser' => NULL,
'objScorm' => NULL,
)
All the properties are retained correctly, and match the class definition for ScormElement. But the class name is wrong. There is no class named LoginLogging.
What is causing this and how do we fix it???
Edit: This is just an example. Other errors are very similar in structure, but affect other class types, and have different incomplete names. However, ALL incomplete names have the same string length of the correct class name.
Edit 2011-10-27: I'm still seeing these error logs, and have had no success in finding a solution. Any help would be appreciated.
PHP 5.3.3, APC, default session handler.
As written in the quote in your question __PHP_Incomplete_Class_Name is a special class name in PHP that is used whenever the class definition could not be found when unserializing (unserialize()).
It's suggested to either ensure the class definition is available or to provide some autoloading for the missing class.
You commented that PHP is looking for the wrong classname here:
wrong: LoginLogging
right: ScormElement
It's hard to say with the information given why the classname is being changed on serialization/unserialization. The information you've given (especially the dump) in your question is incomplete.
So the options are limited to some general suggestions:
You could inspect the serialized string which classname is given in there so you could at least say if it happens with serialization or unserialization. You can easily inspect serialized data with the Serialized PHP Library which has a text-dumper for debug purposes.
Additionally there is the unserialize_callback_func Ini-Directive you can use to further trace the problem.
<?php
$serialized_object='O:1:"a":1:{s:5:"value";s:3:"100";}';
// unserialize_callback_func directive available as of PHP 4.2.0
ini_set('unserialize_callback_func', 'mycallback'); // set your callback_function
function mycallback($classname)
{
// just include a file containing your classdefinition
// you get $classname to figure out which classdefinition is required
}
As you write the problem does not occur any longer, I suspect that at some point the serialization on your site was broken storing invalid data. Which framework/libraries/application are you using? Which component takes care about serialization?
If your trying to access a property method of an object or serialized value you've stored in a $_SESSION variable and you included the class after calling session_start() try including the class before calling session_start();
This happens when we try to initialize the session before loading the class definitions for the object we are trying to save into the session.
you can use simply json methods in PHP
json_encode that array and again json_decode that array and save it in a variable and than print that variable. you will get a simple array.
eg.
$array = array(); // this is your array variable to whom you are trying to save in a session
$encode = json_encode($array);
$decode = json_decode($encode);
echo '<pre>';
print_r($decode);
it will work surely.
Are you, by any chance, using some opcode cache (e.g. APC, XCache) or some debugger? They sometimes cause weird things to happen. If there isn't and never was a LoginLogging class in your project, but yours is not the only project on the server, I would bid on the cache.
To include the class before the session_start() works fine for me. =)
Hakre's suggestion to look at session_write_close led me to what appears to be a reliable fix:
register_shutdown_function('session_write_close');
This forces the session to be written out before any memory cleanup and class unloading occurs. This is important due to a change in PHP that can result in a race condition between APC removing class references and PHP writing out the session data: http://news.php.net/php.internals/46999
When you try to unserialize a variable, php must know the structure of the object. Try to include your class before unserialize. Which class? the one that holds those properties shown in your code. include('pathtoyourclass/classname.php') or include_once('pathtoyourclass/classname.php').
Good luck!
I use this function to solve this problem
$user = $_SESSION['login'];
$auth_user= fixObject($user);
function fixObject(&$object) {
if (!is_object($object) && gettype($object) == 'object')
return ($object = unserialize(serialize($object)));
return $object;
}
It is the serialization issue in your code.It may be your code for some reason could not initialize the object and in next part of your code tries to convert that object to string or some other data type.
Just inspect your code, properly initialize your objects.
Check if you are using serialize()/unserialize() method.
Are you receiving this serialized object from a service/stream or reading it from a file? I've seen it happen in a client-server setting the client side object and the server side objects differ very slightly... maybe have a property that the other doesn't have. This also happens when you serialize an object, save it to file, then refactor code that removes a class and then try's to deserialize the object.
Then when it gets deserialized and tries to instantiate the needed classes they don't exist.
The error is clear and straightforward, you're creating a object for which the class has not been loaded.
I'd do a string search on your code, find where the needed class is located, and make a simple autoloader (or just a raw include/require) of the file. Just get the class it needs loaded somehow.
If the class really doesn't exist anywhere, try checking earlier revisions (I'm assuming you have version control of some type) for existence of the class. If you're deserializing an object generated by another system check that system out as well.
I'm trying to implement a simple way to manage static pages in CakePhp, as described in this article.
The problem I'm facing is that App::import() doesn't seem to import the required class in the routes.php file.
The code is the following:
App::import('Model','StaticPage');
$page = new StaticPage();
$slugs = $page->find('list', array(
'fields' => array('StaticPage.slug'),
'order' => 'StaticPage.slug DESC'
));
I'm getting the error: Fatal error: Class 'StaticPage' not found in ...
This class is present in the models folder (models/StaticPage.php).
I just started CakePhp a few weeks ago and I guess I'm missing a simple thing here...
I'm using CakePhp 1.3 and Php 5.2.42.
I think the reason it doesn't work is because you don't follow CakePHP's naming conventions for file names: file names are lowercase and underscored. So renaming your file to static_page.php should fix the problem.
Having taken a quick look at the article you reference, your snippet doesn't match up. You're importing the ClassRegistry class (which doesn't need to be imported) and then trying to instantiate a StaticPage. I'd recommend removing the AppImport reference all together and using ClassRegistry:
$page = ClassRegistry::init( 'StaticPage' );
You don't need the AppImport line because ClassRegistry::init() both loads the model and instantiates the object.
The other (potential) problem I see is that your model file name doesn't follow convention. It should be models/static_page.php. Cake's inflection may not be handling the deviation from the norm.
Like the error says: You are missing the Class StaticPage. Are you sure that you have this file? If you do, sure that it's in right place, has the right filename so the autoloader can find it?.
