If PHP S3 client connection is not set correctly, you will get following error:
1) Error retrieving credentials from the instance profile metadata server
2) AWS HTTP error: cURL error 60: SSL certificate problem:
For S3 PHP SDK version 3, the correct connection for S3 client as follows:
<?php
require $_SERVER['DOCUMENT_ROOT'] . '/aws/aws-autoloader.php';
use Aws\S3\S3Client;
use Aws\S3\Exception\S3Exception;
use Aws\Common\Credentials\Credentials;
//AWS access info
if (!defined('awsAccessKey')) define('awsAccessKey', 'mykey');
if (!defined('awsSecretKey')) define('awsSecretKey', 'mysecret');
$bucket = 'defashion2u';
try {
$client = S3Client::factory(array(
'version' => 'latest',
'region' => 'us-east-1',
'credentials' => array(
'key' => awsAccessKey,
'secret' => awsSecretKey
),
'http' => [
'verify' => $_SERVER['DOCUMENT_ROOT'] . '/aws/cacert.pem'
]
));
} catch (S3Exception $e) {
echo $e->getMessage() . "\n";
}
?>
The parameter version, region, credentials and SSL cert must be set.

Reuse / Load a Model Anywhere in Joomla 2.5/3.x
Sometimes you may wish to reuse a certain function that resides in a
model outside of your current scope. This helps you save time and reduce
duplication. This can be achieved easily by adding the following codes.
Assuming you are trying to call a model "Categories" (/components/com_mycomponent/models/categories.php) belonging to com_mycomponent (this can be called from either within or outside of the com_mycomponent):
Now you can call its methods, example:
Assuming you are trying to call a model "Categories" (/components/com_mycomponent/models/categories.php) belonging to com_mycomponent (this can be called from either within or outside of the com_mycomponent):
jimport('joomla.application.component.model'); JModelLegacy::addIncludePath(JPATH_SITE.'/components/com_mycomponent/models'); $categoriesModel = JModelLegacy::getInstance( 'Categories', 'MyComponentModel' );
Now you can call its methods, example:
$categoriesModel->getCategories();

components/com_component/controller.php
& other file is components/com_helloworld/helloworld.php
which is pointing to controller.php
file to execute the request. You create new controller
folder and put all controllers
in that folderThe main controller is typically used to do what you mention in your comment (render a view based on the
view
parameter, usually specified in the URL). In controller.php
, the function that does this is called display()
. So the following URL:http://example.com/index.php?option=com_mycomponent&view=test
Will result in calling the
display()
function in controller.php
and loads the view test
in /views/test
.Subcontrollers, in the
controllers
folder, are generally used for CRUD tasks, but can be called easily by using a task
URL parameter. For example:http://example.com/index.php?option=com_mycomponent&task=test.process
Will result in calling the
process()
function in /controllers/test.php
- notice the task
parameter is <controllerName>.<functionName>
How to switch the ‘action’ field in an HTML form dynamically
It is often required that you need to send the data in the same form to
different server-side scripts depending one certain criteria. JavaScript
allows you to modify the action field of an HTML form dynamically. Multiple submit buttonsIt is possible to have more than one submit button in a form. The example below shows how to switch the action field based on the submit button pressed. <script type= "text/javascript" > function OnSubmitForm() { if (document.pressed == 'Insert' ) { document.myform.action = "insert.html" ; } else if (document.pressed == 'Update' ) { document.myform.action = "update.html" ; } return true ; } </script> |
< form name = "myform" onsubmit = "return onsubmitform();" > < input type = "submit" name = "operation" onclick = "document.pressed=this.value" value = "insert" /> < input type = "submit" name = "operation" onclick = "document.pressed=this.value" value = "update" /> </ form > Based on a radio buttonThe example below shows a case where the action field is switched based on the selection in the radio buttons.
