I'm using Yii PHP Framework and MemCache for caching and when I open not cached page for the first time I see this error:
Live error error log off (linux):
Fatal error: Call to a member function getColumnNames() on a non-object in /home/cineshell/cineklik/framework/db/ar/CActiveFinder.php on line 385
Locally with error log (windows):
Trying to get property of non-object
C:\xampp\htdocs\appfolder\framework\yiilite.php(7125)
...
7123 public function getTableSchema()
7124 {
7125 return $this->getMetaData()->tableSchema;
7126 }
config/main:
'cache'=> array(
'class'=> 'CMemCache',
'servers'=>array(
array('host'=>'localhost', 'port'=>11211, 'weight'=>100),
),
),
Cache example:
$data = Yii::app()->cache->get( 'casheID' );
if($data===false)
{
$data = dataprovider, query... etc
}
echo $data;
So, what's error here ?, and could be something in server settings ?
someone told me use if isset but I'm not understand !
For CActiveDataProvider, please follow this guide.

For alternative, you can use fragment cache the gridview or the partial view depending the needs. I've also struggeled with it and I found that query cache was the only working solution.

I installed phalcon 3.0.1-14 on an Ubuntu 14.04 box. Also installed Phalcon DevTools (3.0.1).
Initially, I enabled the webtools and when I visit that page, some warnings appear all the time:
Cannot bind an instance to a static closure in /home/pish/vendor/phalcon/devtools/scripts/Phalcon/Web/Tools.php
Cannot bind an instance to a static closure in /home/pish/vendor/phalcon/devtools/scripts/Phalcon/Web/Tools/views/index.phtml
I just ignored them and tried to create a model out of an existing table in the database. When I clicked on "Generate" button
I get the following error:
Phalcon\Mvc\Dispatcher\Exception: ModelsController handler class cannot be loaded
and the model is not created. I tested creating a controller as well, but a similar error occurred and the controller
was not created either.
Finally, I created the model via the console phalcon model users and it was created successfully.
I noticed, though, that the validation function created by the developer tools doesn't work and causes the following
error when I try to create a user:
Catchable fatal error: Argument 1 passed to Phalcon\Mvc\Model::validate() must implement interface Phalcon\ValidationInterface, instance of Phalcon\Mvc\Model\Validator\Email given in...
My question is basically, is there something bad with the version of developer tools I installed that causes the problems
with the Webtools and the functions that are generated for models/controllers, etc.? Or I might have something wrong
in my system?
Cannot bind an instance to a static closure
https://github.com/phalcon/cphalcon/issues/11029
Catchable fatal error: Argument 1 passed to Phalcon\Mvc\Model::validate()
Fixed in the 3.0.x branch (will be released soon)
Regarding your second error message:
Catchable fatal error: Argument 1 passed to Phalcon\Mvc\Model::validate() must implement interface Phalcon\ValidationInterface, instance of Phalcon\Mvc\Model\Validator\Email given in...
Model validation has changed in Phalcon 3.0. In Phalcon v2 you had to do
public function validation()
{
$this->validate(
new Phalcon\Mvc\Model\Validator\Email(['field' => 'email']);
);
if ($this->validationHasFailed() == true) {
return false;
}
}
But the Phalcon\Mvc\Model\Validation is deprecated in v3 and you should use Phalcon\Validation instead. Just alter your code to the following:
public function validation()
{
$validator = new Validation();
$validator->add(
'email', //your field name
new Phalcon\Validation\Validator\Email([
'model' => $this,
'message' => 'Please enter a correct email address'
])
);
return $this->validate($validator);
}
Maybe the DevTools haven't updated this part yet, I am not sure.
I wonder how can I find my moodle's database contents.
I want to elaborate users etc.
My first try is with PHP code using global $DB but there is an error message:
Fatal error: Call to a member function get_record() on a non-object in C:\xampp\htdocs\test.php on line 3
I use the getrecord() function but I didn't do it right.
Can anybody help me? The name of my database is "base".
Note: moodle version is 2.7.2
This is an example that should allow you to access the Moodle DB.
require_once(dirname(__FILE__).'/../../config.php'; // Insert as many '/../' as you need to get from the subdirectory your file is in, back up to Moodle's config.php
function my_function() {
global $DB;
$record = $DB->get_record('user', array('id' => 2));
var_dump($record);
}
my_function();
I've been searching on Internet and on stackoverflow, but i didn't find a solution, or it wasn't the same problem.
I need to load two models in the same controller, and in the same function. One is "model_membre" and the other "model_annonce". It's the name of the class, the file, and the object.
Individually, they work very good, i can access to properties and methods, but when I'm loading the two models, I can't access to the second, regardless of how I load it (autoload, $this->load->model('model_name'), $this->load->model('model_name', 'object_name')).
I simplified to a "test" controller, to see if it was not another part of my code that made the problem :
public function index()
{
$this->load->model('model_membre', 'membre');
$this->load->model('model_annonce', 'annonce');
$liste = $this->annonce->listerEspeces();
$membre = $this->membre->obtenirMembre(1);
}
I tried to changer the order, and the 2nd loaded never works. I get this message :
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Test::$annonce
Filename: controllers/test.php
Line Number: 15
Fatal error: Call to a member function listerEspeces() on a non-object in /homez.604/animalix/beta/application/controllers/test.php on line 15
Please try the following way...
public function index()
{
$this->load->model(array('membre','annonce'));
$liste = $this->annonce->listerEspeces();
$membre = $this->membre->obtenirMembre(1);
}
The models should extend CI_Model and not CI_Controller! This was the source of the problem.
I was trying to implement some new functionality, decided not to, tried to roll back, and now am stuck with this error:
Fatal error: Call to a member function insert() on a non-object in /app/code/core/Mage/Core/Model/Mysql4/Resource.php on line 96
The functionality I mentioned seems simple enough (remove a couple links from the customer account sidebar), and I believe I've removed the 3 files and the edit to local.xml, but just for full view on things, here's exactly what i did.
Add'l info: I've got one custom module in place that I built for this site, and it was working prior to this glitch, but I'm wondering if something got screwed up in there maybe? (And I'm also thinking I might not have committed my last/working change, and now I'm in "doubt" territory about whether I screwed that up. It's a simple one though: 1 controller, 1 route.)
I've got no access to PHP error logs or the shell (exec() works great though), and the /var/system.log isn't adding anything more on my subsequent page-refreshes. And so this is where I'm stuck - Got any ideas on how to track this down? Thanks in advance!
Edit / here's the function that's throwing the error:
function setDbVersion($resName, $version)
{
$dbModuleInfo = array(
'code' => $resName,
'version' => $version,
);
if ($this->getDbVersion($resName)) {
self::$_versions[$resName] = $version;
$condition = $this->_write->quoteInto('code=?', $resName);
return $this->_write->update($this->_resTable, $dbModuleInfo, $condition);
}
else {
self::$_versions[$resName] = $version;
// this is line 96:
return $this->_write->insert($this->_resTable, $dbModuleInfo);
}
}
I'm doing some testing to my login form but I notice that If I dont send all the expected parameters, I get this error:
Fatal error: Call to a member function hasResource() on a non-object in C:\demo\application\controllers\ErrorController.php on line 47
for example this test code gives me error:
public function testLoginPage ()
{
$this->request->setMethod('POST')->setPost(
array('username' => 'foobar');
$this->dispatch('/usuario/login');
}
But if I send all the elements everything works as expected:
public function testLoginPage ()
{
$this->request->setMethod('POST')->setPost(
array('username' => 'foobar','password' => 'secret');
$this->dispatch('/usuario/login');
}
Is this normal? I dont understard why I get an error on ErrorController.php, where is the connection?
(I thought that maybe is something that not loading, but why is it working when all elemnts are?)
Any help understanding this will be appreciated.
Thanks
Update:
I just change to an incorrect password for db database in the application.ini and that gives me the same error. Now I dont even think is the form but maybe some call at the bootstart that is depending to the Zend_Auth identity. But what means that Fatal error: Call to a member function hasResource() on a non-object? how to load that object?
Read the error message you get. You're calling hasResource() on a non-object in ErrorController.php. Your error controller is broken, but that's not really the issue here.
The issue is that there's an exception being thrown somewhere (possibly in your form, bootstrap, or anywhere really) which triggers the error controller. Fix or disable the error handler to get the exception message and stack trace to find out your problem.
To disable the error handler
$front = Zend_Controller_Front::getInstance();
$front->setParam('noErrorHandler', true);
