I am trying to accomplish something which I think is getting beyond my current PHP skills!
I have working code in a Magento .phtml template file that calls an external PHP class e.g.
$ExternalLibPath=Mage::getModuleDir('', 'My_Module') . DS . 'lib' . DS .'class.authentication.php';
require_once ($ExternalLibPath);
$myauth = new Authentication();
$credentials = $myauth->get("account_credentials");
echo "Connecting as " . $credentials->user_name ;
(In the .phtml file the classes are called from an include). I'm trying to move the code from the frontend template files to a Magento module/extension with a class triggered on an event. My module works fine up until the external classes are accessed where trying to access *$credentials->user_name* causes an Undefined property: stdClass: error.
I don't understand why the code works in a .phtml template and not in the module, or what I am doing wrong!
Any help would be appreciated.
Pete.
You should call the class directly from the phtml:
$credentials = Mage::getModel('namespace/custom_class')->getAccountCredentials();
and return whatever you need to.

I am integrating google spreadsheet in my project. I have to save form data into google spreadsheet.
For this i am using asimqt php-google-spreadsheet-client library.
I have single form on site that form is submitting using ajax. For this i have written function in function.php.
Getting error when initializing object of DefaultServiceRequest class.
Error: Fatal error: Class 'Google\Spreadsheet\DefaultServiceRequest' not found
require '/vendor/autoload.php';
use Google\Spreadsheet\DefaultServiceRequest;
use Google\Spreadsheet\ServiceRequestFactory;
function spreadsheet_feeds()
{
$access_tok = 'xyz-token';
$serviceRequest = new DefaultServiceRequest($access_tok); // Getting error
ServiceRequestFactory::setInstance($serviceRequest);
$spreadsheetService = new Google\Spreadsheet\SpreadsheetService();
$spreadsheetFeed = $spreadsheetService->getSpreadsheets();
}
add_action( 'wp_ajax_nopriv_spreadsheet_data', 'spreadsheet_feeds' );
add_action('wp_ajax_spreadsheet_data','spreadsheet_feeds');
Any help why this error is occurring because class is already include using "use" statement ?
This seems to be an issue with the location of your vendor folder.
Make sure that the vendor folder is accessible by the file
Considering your folder hierarchy to be
-wp-content
--themes
---your-theme
----functions.php
If you have your vendor folder in your-theme/vendor then in your functions.php
you should write
require 'vendor/autoload.php';
and if vendor is in the root directory of WP make sure you traverse back to the root folder using something like :
require __DIR__ .'/../../../../vendor/autoload.php';
Just replace require '/vendor/autoload.php'; to require_once('vendor/autoload.php');
Just now I tried this here for you myself and it works.
I have a PHP class inside my Wordpress plugin that is activated in a website. I want to use a method (doc_export function) that is defined inside this class in another plugins (also activated in the same website). I add this one and it seems working:
<?php
// Export doc
if (defined('DOC_ADMIN_MODE')) {
$my_Documentation = new Class_Documentation;
$mydocexport = $my_Documentation->doc_export();
$mydocexport_file = ABSPATH . '_export/' . basename($site['site_url']) . '/doc.xml';
file_put_contents($mydocexport_file, $mydocexport);
}
?>
I want to know if this is the proper approach..Thanks.
Yes that's the proper approach. You can also read about the OOP basis in PHP at http://php.net/manual/en/language.oop5.basic.php
So my project uses an MVC framework and I have a page with an Ajax script I run to get content from the server. When the PHP script is called in the Ajax script, I want to access the classes already in my library for use in the PHP script. To do this, I use what I call an ajaxBootstrap to call the appropriate function that then instantiates the objects needed for that specific Ajax script.
To load those classes from my library I have an autoload function in my ajaxBootstrap so I don't need to use a bunch of require and include statements. My problem is those files aren't being loaded due to a path issue with the autoload function. When I use a require statement with the same path, the classes load with no problems, its only when I try to load them using the autoload function that I get an 500 internal server error.
Here is my ajaxBootstrap file:
// This file routes Ajax requests made in JS files and instantiates a specific object to carry out the actions needed for that particular Ajax operation
// Autoload any classes that are required
function autoLoad($classToLoad)
{
if(file_exists('../library/' . $classToLoad . 'class.php')) // File in the library folder
{
require('../library/' . $classToLoad . '.class.php');
}
else if(file_exists('../../app/models/' . $classToLoad . 'class.php')) // File in the models folder
{
require('../../app/models/' . $classToLoad . '.class.php');
}
}
spl_autoload_register('autoLoad');
// Determine which function to call based on the url that's listed in the Ajax request
switch($_GET['action'])
{
case 'pageOne':
pageOne();
break;
case 'pageTwo':
pageTwo();
break;
}
function pageOne()
{
$test = new Test();
$test->funcThatReturnStuff();
}
function pageTwo()
{
$test2 = new Test2();
$test2->funcThatReturnStuff();
}
Like I mentioned eariler, if I use a require statement such as:
require('../library/Test.class.php');
$test = new Test();
$test->funcThatReturnStuff();
The class loads and works just fine. But using the same path in the autoloader function throws an error. The really odd thing is if I put an else if statement in the autoloader that loads a class from the folder where my ajaxBootstrap is it also works fine too...
I know I could just use the require statements and be done with the problem but I want to be able to scale the project and not need to use loads of require statements in the future. BTW, I use '../' to get from where my ajaxBootstrap file is to my other folders.
Also, to add to my previous post, I've tried replacing the ../ with absolute paths using define('ROOT', dirname(__FILE__) . '/') and also define('ROOT', $_SERVER['DOCUMENT_ROOT'] . '/path/to/folder/') neither of which worked and still gave me the internal server error in Firebug. In addition, I haven't received any errors in my error log either.
Nevermind... Even after staring at my code for the past few hours I somehow missed the missing period in two of my file paths. I hate coding sometimes... Thank you to anyone who took time to read this.
im currently working on some sort of upload with automatic video conversion. At the moment i am executing a php script via php shell command after the upload is finished so the user doesn't have to wait until the conversion is completed. Like so:
protected function _runConversionScript() {
if (!exec("php -f '" . $this->_conversionScript . "' > /dev/null &"))
return true;
return false;
}
Now in my conversion script file i am using functions from another class "UploadFunctions" to update the status in the database (like started, converted, finished...). The problem there is though that this UploadFunctions class inherits from another class "Controller" where for example the database connection gets established. Currently i am using spl_autoloader to search specific directories for the files needed (for example controller.php), but because the conversion script is out of context with the whole autoloader stuff it doesn't recognize the Controller class and throws an fatal php error.
Here is some code from the conversion script:
require_once('uploadfunctions.php');
$upload_func = new UploadFunctions();
// we want to make sure we only process videos that haven't already
// been or are being processed
$where = array(
'status' => 'queued'
);
$videos = $upload_func->getVideos($where);
foreach ($videos as $video) {
// update database to show that these videos are being processed
$update = array(
'id' => $video['id'],
'status' => 'started'
);
// execute update
$upload_func->updateVideo($update);
.........
Am i doing this completly wrong or is there a better way to accomplish this? If you need more code or information please let me know!
Thanks a lot
Here is my spl_autoload code:
<?php
spl_autoload_register('autoloader');
function autoloader($class_name) {
$class_name = strtolower($class_name);
$pos = strpos($class_name ,'twig');
if($pos !== false){
return false;
}
$possibilities = array(
'..'.DIRECTORY_SEPARATOR.'globals'.DIRECTORY_SEPARATOR.$class_name.'.php',
'controller'.DIRECTORY_SEPARATOR.$class_name.'.php',
'..'.DIRECTORY_SEPARATOR.'libs'.DIRECTORY_SEPARATOR.$class_name.'.php',
'local'.DIRECTORY_SEPARATOR.$class_name.'.php'
);
foreach ($possibilities as $file) {
if(class_exists($class_name) != true) {
if (file_exists($file)) {
include_once($file);
}
}
}
}
?>
I have my project divided into subfolders wich represent the functionality, for example upload, myaccount and gallery.. in every subfolder there are also 2 other folders: controller and local. Controller is the class controlling this part (upload for example) and local is the folder where i am putting the local classes wich are needed. The controller class gets called from the index.php wich is located in the sub-project folder. "libs" and "global" are just projectwide classes, like database, user and so on.
This is an example of my folder structure:
www/index.php // main site
www/upload/index.php // calls the controller for upload and initializes the spl_autoload
www/upload/controller/indexcontroller.php // functionality for the upload
www/upload/local/processVideo.php // this is the conversion script.
I am fairly new to spl_autoload function. In my opinion the spl_autoload is not getting called if my script is calling: "php -f processVideo.php", isn't it?
PHP relative paths are calculated from the path where PHP binary is called.
I suggest you to use __DIR__ constant to avoid that behavior
http://php.net/manual/en/language.constants.predefined.php
I was actually able to resolve the issue. I had to include the spl_autoload_register function inside the conversion script so that it was able to locate the files. This was an issue because the conversion script is not build into my framework an so it isn't able to load the classes from the framework autoloader.
I'm starting off with both php and Joomla development, and finding it difficult working within Joomla to do some fairly simple stuff. Went through the Joomla MVC example and Lynda (and have built a few simple views so far).
I have a helper file/class/function that outputs all the userids that exist in the "completed" table so I can display a link for either a new record based on that user or edit an existing user's record.
I've already used a different function in this helper file successfully in a different part of the component ( Joomla: Write and call a helper function in a component ).
When I do the same thing in the model, I'm getting this: "Fatal error: Call to protected method JModel::_createFileName() from context 'JView' in C:\wamp\www\ilplocal\libraries\joomla\application\component\view.php on line 773". When I try it in the view, works fine - but I need the output in the model.
Code:
lookups.php
abstract class LookupHelper {
public function other_functions($vars){
...
}
public function completions_exist() {
$db =& JFactory::getDBO();
$query = $db->getQuery(true);
$query->SELECT(' #__completed.completed_userid as UserID');
$query->FROM (' #__completed');
$query->GROUPBY (' #__completed.completed_userid ');
$db->setQuery($query);
$result = $db->loadResultArray(0);
return $result;
}
}
In the model:
$completions_exist = Jview::loadHelper('lookups');
$completions_exist = LookupHelper::completions_exist();
This line is throwing the error: $completions_exist = Jview::loadHelper('lookups');
I've found some really vague references to something called JLoader::register to pull in helper functions but can't find any good documentation on that in Joomla except for everyone saying to just use that. SO I tried using it like so:
JLoader::register('LookupHelper', dirname( JPATH_COMPONENT_ADMINISTRATOR).DS.'helpers'.DS.'lookups.php');
$completions_exist = LookupHelper::completions_exist();
which throws this error: "Fatal error: Class 'LookupHelper' not found in C:\wamp\path\to\model\not\to\lookups.php. Tried manipulating the JLoader::register(everything here) and it doesn't effect the path of the error message.
Thoughts? Why does it work in a view and not in the model? How do I use the helper functions within a model?
Thanks!
#####EDIT
Thanks to #cppl looks like it's a path issue with the second bit of code. Also I read that the .DS. notation will be phased out in future versions - so the code that's working is:
JLoader::register('LookupHelper', JPATH_COMPONENT_ADMINISTRATOR.'/helpers/lookups.php');
$completions_exist = LookupHelper::completions_exist();
Lets break this down:
In Joomla! your components helper file should be in `/mycomponent/helpers/lookup.php'
JLoader:: is the Joomla! way to do it, but you could just as easily use PHP's require_once eg. require_once JPATH_COMPONENT_ADMINISTRATOR.'/helpers/myfunctions.php';
Is your path right? - you're providing dirname(JPATH_COMPONENT_ADMINISTRATOR).DS.'helpers'.DS.'lookups.php' but you've wrapped the path to your component in dirname which will the parent element of the path only. So JLoader is looking in /administrator/helpers/lookups.php.
JPATH_COMPONENT_ADMINISTRATOR is initialised as part of Joomla!'s renderComponent() call in it's JComponentHelper class if you apply dirname to it when it's not setup you will get back a dot (ie. current directory) so in the model you could would be passing ./helpers/lookups.php to the JLoader call.
You can call helper within model by following method:
JLoader::import('helpers.events', JPATH_COMPONENT);
this will include the file helpers/events.php from the component directory.
$_helper = new EventsHelper();
echo $_helper->getAnyInsideMethod();exit;
