I have installed the plugin WPdeposit on my wordpress site, it allows users to deposit into their account balance. I am trying to manipulate users balances when they press an anchor tag on the page.
In the directory plugins/models/user.php there are many functions, I think im interested in this one:
/**
* Update Regular balance to given amount (Will overwrite whatever value is in the db!)
*
* #param int $amount
* #return boolean
*/
public function updateRegularBalance($amount) {
if (floatval($amount)) {
return (bool) update_user_meta($this->_id, WPDEPOSIT_NAME.self::USER_AMOUNT, $amount);
} else {
throw new \Exception(__('Amount is not a number', WPDEPOSIT_NAME));
}
}
when I try to call this function to the page on the theme's index.php like so:
updateRegularBalance(5);
but I receive this error.
Fatal error: Call to undefined function updateRegularBalance()
is there a way to access the use of this function so I can pass in the value I want to update the balance to?
$class = new UserModel();
$class->updateRegularBalance(9999);
it was never a function I was trying to use, it was a method.

I just started with Apigility and oAuth2, and I was wondering if it is possible to get the currently authenticated "loggedin" user when fetching information from a database.
I currently have the following code:
/**
* Fetch all or a subset of resources
*
* #param array $params
* #return mixed
*/
public function fetchAll($params = array())
{
var_dump($params);
// Using Zend\Db's SQL abstraction
$sql = new \Zend\Db\Sql\Sql($this->db);
//I would like to get the currently logged in user here... but how?
$select = $sql->select('projects')->where(array('userid' => 1));;
// This provides paginated results for the given Select instance
$paged = new \Zend\Paginator\Adapter\DbSelect($select, $this->db);
// which we then pass to our collection
return new ProjectsCollection($paged);
}
I did a lot of searching already but I have no clue how to access the user information or the access token, do I need to parse the request header for this?
I was also looking for it. I didn't found any documentation about that. But the answer is quite simple:
Resource classes inherits ZF\Rest\AbstractResourceListener which already has a method getIdentity.
/**
* Fetch all or a subset of resources
*
* #param array $params
* #return mixed
*/
public function fetchAll($params = array())
{
// if user isn't authenticated return nothing
if(!$this->getIdentity() instanceof ZF\MvcAuth\Identity\AuthenticatedIdentity) {
return [];
}
// this array returyour query here using $userIdns the authentication info
// in this case we need the 'user_id'
$identityArray= $this->getIdentity()->getAuthenticationIdentity();
// note, by default user_id is the email (username column in oauth_users table)
$userId = $identityArray['user_id'];
// fetch all using $userId
}
You can also use getIdentity in RPC services.
I'm using the latest version of apigility.
I found in the end a shorter way to get the userid, just adding it as answer for the sake of completeness.
You can get the identity object like #VinÃciusFagundes mentioned $this->getIdentity() and this identity object has the function getRoleId() which returns the identifier of the user.
$user_id = $this->getIdentity()->getRoleId();
I am building an intranet application and i want to be able to have 2 different types of users a regular user and an admin user. I am trying to figure out what would be the best way to go about doing this. Either to have one object for admin type stuff and then one object for user type stuff. Or combine both of that into one object. But i keep getting stuck and not sure how to go about doing that, or if that is even the best way.
Lets say I have the following situations:
1. query the db to get all tasks for all projects that are active.
Admin Query
2. query the db to get all tasks for all projects that are due today and active.
Admin Query
3. Query the db to get all tasks for a specific project that are active.
Admin Query
User Query
4. Query the db to get all tasks for a specific project that are active and due today.
Admin Query
User Query
5. Query the db to get all tasks for a specific project.
Admin Query
User Query
6. Query the db to get all tasks for a specific project, with different status specified.
Admin Query
7. Any one of those queries has an optional parameter to either get the count or the data.
I started the following object but now im a little stuck as which route to go:
public function getTasks($status, $project, $type = "count", $duetoday = NULL)
{
try
{
if($duetoday != NULL){
$today = date("Y-m-d");
$stmt = $this->db->prepare("SELECT * FROM tasks WHERE status=:status
AND $project=:project AND duedate BETWEEN :duedate
AND :duedate");
$stmt->execute(array(':status'=>$status,':project'=>$project,':duedate'=>$today));
}else{
$stmt = $this->db->prepare("SELECT * FROM tasks WHERE status=:status
AND $project=:project");
$stmt->execute(array(':status'=>$status,':project'=>$project));
}
$tasks=$stmt->fetch(PDO::FETCH_ASSOC);
if($stmt->rowCount() > 0)
{
if($type == "count"){
return $stmt->rowCount();
}else{
return $tasks;
}
}else{
return false;
}
}
catch(PDOException $e)
{
echo $e->getMessage();
}
}
I will start with some words about the single responsibility principle. Basically, this means that an object and it's behaviors should have one responsibility. Here, I think your getTasks method is a good opportunity to refactor some code into better object oriented code.
There are actually many things it is doing:
Generate sql
Execute a query
Control the flow of the program
The method generating sql should not have to worry about it's execution, and the method executing it should not have to worry about getting it. This, as a side effect, will also reduce the nesting in a single method.
There is a lot of code to write, which I'll let you do, but if you create classes that implements those interfaces and a controller to use them, you should be able to get through this and write easier to maintain / refactor code:
interface SqlGenerating {
/**
* #param array $params
* #return string
*/
public function makeSql(array $params);
/**
* #param array $params
* #return array
*/
public function makeValues(array $params);
}
interface DBAccessing {
public function __construct(\PDO $pdo);
/**
* #param string $sql
* #param array $values
* #return PDOStatement
*/
public function getStmt($sql, array $values = []);
}
class Controller {
public function __construct(SqlGenerating $sqlGenerator, DBAccessing $dbAccess) {
// associate to private properties
}
public function getTasks($status, $project, $type = "count", $duetoday = null) {
// this function will use the sqlGenerator and the dbAccess to query the db
// this function knows to return the count or the actual rows
}
}
If you haven't already, this is a good time to learn about type-hinting in functions. This requires your function to be passed an object (or an array) to be assured of the behavior of the function. Also, you will notice that I type-hinted the interfaces into the controller. This is to actually be able to switch classes if ever you need a different one to manage sql and db access.
I'm working with Restler and the OAuth2 module written by Brent Shaffer. What I want to do is determine the user from the token they send, inside my app classes, not just the OAuth2Server classes.
There are two methods that I can see of doing this. Hopefully this explains what I am trying to do.
Method 1: I don't particularly like this method, but it works.
POST /v1/token
Returns my token including the user_id, for example
{
"access_token":"282090609b3407d981c2bea633a39739595ba426",
"expires_in":3600,
"token_type":"Bearer",
"scope":"basic",
"refresh_token":"b60a4e5f759168df857342380f3550bc120b6f9d",
"user_id": 5
}
Now that the client knows the user_id, it is sent with my request:
GET /v1/dashboard?id=5
My __isAllowed method takes care of checking that the user hasn't altered the id, requesting info that isn't theirs.
public function __isAllowed() {
$token = static::$server->getAccessTokenData(Request::createFromGlobals());
return (($token['user_id'] > 0) && ($token['user_id'] === $_GET['id']) && ($token['group_id'] == self::$group_id));
}
Dashboard class looks like this:
/*
* #version 1
* #access protected
*/
class Dashboard {
/**
* #param int $id Customer ID {#from query}
* #return type
*/
public function index($id) {
$s = Dao\ViewCustomerDaoObject::findId($id);
return array_merge($s->toJSON(), $widgets);
}
}
This is how I would prefer to be calling the API:
GET /v1/dashboard
When I request the above, join the oauth2_token table to my dashboard table. I think this might be a bit of a hack and I don't want this to cause problems down the road.
The info is already available in the OAuth2Server instance, as the OAuth2Server class does determine if the correct token is used and what their user_id is.
Can someone please guide me in the right direction for handling this situation, particularly with Restler?
I actually figured this out myself.
In the OAuth2Server->__isAllowed method, you must set the UserId in the static User class.
public function __isAllowed() {
$token = static::$server->getAccessTokenData(Request::createFromGlobals());
// If the user_id is valid, set static user class.
// *** This is not production code, add more checks here if you use this!
if ($token['user_id'] > 0) {
\Luracast\Restler\User::init();
\Luracast\Restler\User::setUniqueIdentifier($token['user_id']);
return true;
}
return false;
}
Now you can get the currently authenticated user in your class by calling:
\Luracast\Restler\User::getUniqueIdentifier(true)
Whenever a user searches, I get this error:
2012-06-26 11:05:21.671 [NOTICE] [208.69.120.120:48175-0#hostname] [STDERR] PHP Fatal error: Call to undefined method Mage_Catalog_Model_Resource_Product_Flat::getEntityTablePrefix() in /chroot/home/SITENAME/DOMAIN.COM/html/app/code/core/Mage/Eav/Model/Entity/Attribute/Abstract.php on line 505
And instead of the user's results appearing, they get a blank white page- no error on their end, no UI, just white. This was the first issue I noticed, but on the same day the following issues started coming up:
White Search Results
Sub-category product count for all sub-categories in layered nav is showing 0.
Some customers can not view orders from their front-end UI when logged in.
Our order export script is returning blank fields (1.7mb instead of 4.3).
Our "Made-in-the-usa" and "best sellers" pages are returning more products than they should.
Now, I know these are all incorrect because if I reindex the entire site, for some period while it is processing the index, all of the above works. However, when the index is complete, it all breaks again. The same day this happened we had an error page appear that stated one of the tables had broken and should be repaired. We ran PHPMyAdmin's repair and optimize functions on all tables and it fixed that error- but all of these are still broken.
Any ideas at all? Any ideas of what could be tried to fix this? I cant find this error anywhere- and the guys over at Nexcess haven't been able to find anything for this, either.
Thank you for your time.
As per the comments above, Magento's telling you that it's trying to call the method getEntityTablePrefix on an object whose classes don't have that method defined. Specifically in this method
#File: app/code/core/Mage/Eav/Model/Entity/Attribute/Abstract.php
public function getBackendTable()
{
if ($this->_dataTable === null) {
if ($this->isStatic()) {
$this->_dataTable = $this->getEntityType()->getValueTablePrefix();
} else {
$backendTable = trim($this->_getData('backend_table'));
if (empty($backendTable)) {
$entityTable = array($this->getEntity()->getEntityTablePrefix(), $this->getBackendType());
$backendTable = $this->getResource()->getTable($entityTable);
}
$this->_dataTable = $backendTable;
}
}
return $this->_dataTable;
}
Given this happens from the following class
Mage_Catalog_Model_Resource_Product_Flat
It says to me that you have an extension and/or customization done that assumes you're not using the flat catalog data tables and wasn't coded to work with the flat table.
Dropping in a debugging call like this
if(!is_callable(array($this->getEntity()),'getEntityTablePrefix'))
{
mageDebugBacktrace();
//debug_print_backtrace();
exit;
}
right before the offending call (in a local code pool override, of course), will print out a call-stack that should point the offending code.
The seems that problem is in Mage_CatalogSearch_Model_Resource_Search_Collection::_getSearchEntityIdsSql that is not compatible with using the product flat index.
You can rewrite class Mage_CatalogSearch_Model_Resource_Search_Collection and do two little modifications.
1) Add new function _getSearchEntityIdsSqlUsingFlatIndex to rewrited class. This new function (I hope) does exactly the same thing as original _getSearchEntityIdsSql, but with using the product flat index.
2) Modify function _getSearchEntityIdsSql so that it calls new _getSearchEntityIdsSqlUsingFlatIndex if the catalog product flat index is enabled and built.
See source code:
class VENDOR_MODULE_Model_PATHTOREWRITECLASS extends Mage_CatalogSearch_Model_Resource_Search_Collection {
/**
* Retrieve SQL for search entities using product flat index.
*
* #param $query
* #return Varien_Db_Select
*/
protected function _getSearchEntityIdsSqlUsingFlatIndex($query)
{
/* #var $coreHelper Mage_Core_Model_Resource_Helper_Abstract */
$coreHelper = Mage::getResourceHelper('core');
$likeOptions = array('position' => 'any');
$flatTableName = $this->getTable('catalog/product_flat').'_'.$this->getStoreId();
/** #var Varien_Db_Select $select */
$select = $this->getConnection()
->select()
->from($flatTableName, array('entity_id'));
foreach ($this->_getAttributesCollection() as $attribute) {
/** #var Mage_Catalog_Model_Entity_Attribute $attribute */
if ($this->_isAttributeTextAndSearchable($attribute)) {
$attributeCode = $attribute->getAttributeCode();
$dbFieldName = in_array($attribute->getFrontendInput(), array('select', 'multiselect'))
? $attributeCode.'_value'
: $attributeCode;
if ($this->getConnection()->tableColumnExists($flatTableName, $dbFieldName)) {
$select->where($coreHelper->getCILike($dbFieldName, $this->_searchQuery, $likeOptions));
} else {
Mage::log(__METHOD__.": Attribute '$attributeCode' is missing in flat index.", Zend_Log::NOTICE);
}
}
}
return $select;
}
/**
* Retrieve SQL for search entities
*
* #param unknown_type $query
* #return string
*/
protected function _getSearchEntityIdsSql($query)
{
// HACK - make compatibility with flat index
/** #var Mage_Catalog_Helper_Product_Flat $flatHelper */
$flatHelper = Mage::helper('catalog/product_flat');
if ($this->getStoreId() > 0
&& $flatHelper->isEnabled($this->getStoreId())
&& $flatHelper->isBuilt($this->getStoreId())
) {
return $this->_getSearchEntityIdsSqlUsingFlatIndex($query);
}
// END HACK
return parent::_getSearchEntityIdsSql($query);
}

my problem is the following: I am writing a login library.
This library has a function _validation() and this uses the validation library to validate the data.
With using normal validation methods it works just fine, but using a callback function just does not work. It is not called.
I call it like this.
$this->CI->form_validation->set_rules('user', 'Username', 'required|callback__check_user');
The functions name is _check_user and it uses the username _check_user($user).
The function itself works fine and I can also call it in the class ($this->_check_user('username')) with a working result.
I am guessing, there might be a problem because I am not workin in a controller so I have a CI instance $this->CI instead of just the original instance $this->
Does anyone have a clue how to fix this?
Thanks in advance.
Hey, I figured out a way that works for me. By just extending the Form_validation library in MY_Form_validation.php you can create custom validation methods. I think it is a clean way and it works perfectly fine. I build the below validation method to check for existing usernames and passwords. $value is something like table_name.fieldname.
I have not message set so that it will use the _exist messages from the lang files.
/**
* Exist
*
* checks if the entry exists in the database
* returns a boolean
*
* #access private
* #param string
* #param field
* #return boolean
*/
function _exist($str, $value)
{
list($table, $column) = explode('.', $value, 2);
$query = $this->CI->db->query("SELECT COUNT(*) AS count FROM $table WHERE $column = '$str'");
$row = $query->row();
return ($row->count > 0) ? TRUE : FALSE;
}
Thanks for your help though.
The form validation callback will only fire on a method inside the current controller.
Just do this in the controller you're using the callback:
function _check_user($user)
{
$this->load->model('login');
$result = $this->login->_check_user($user);
return $result;
}
