How to set a component's param dynamically?

Question

To retreive a param I use:

$myparam = JComponentHelper::getParams('com_mycomponent')->get('myparam');

But what is the right method to store a component's param?

Answer 1

Many of our component's parameters depend on external conditions, so we need to periodically change them with some overnight processing. Here's the code we use (adapted for use with com_content).

// Load the current component params.
$params = JComponentHelper::getParams('com_content');
// Set new value of param(s)
$params->set('show_title', 1);

// Save the parameters
$componentid = JComponentHelper::getComponent('com_content')->id;
$table = JTable::getInstance('extension');
$table->load($componentid);
$table->bind(array('params' => $params->toString()));

// check for error
if (!$table->check()) {
    echo $table->getError();
    return false;
}
// Save to database
if (!$table->store()) {
    echo $table->getError();
    return false;
}
