trigger event after customer login

Opencart 3.0
I would like to run a function that uses the customer_id after the customer is logged in. Here is my setup

Code: Select all

event: 'my_event', 'catalog/controller/account/login/after', 'extension/module/my_event/updateCustomer'

function updateCustomer($route = '', $args = array(), $output = '') {
  $this->log-_write($route);
  $this->log-_write(print_r($args, true));
  $this->log-_write($output);
  $this->log-_write($this->customer->getId());
}
After the customer logged in, I see $route output "account/login" but nothing for $args, $output, or $this->customer->getId(). Am I doing something wrong? How do I get customer_id after the customer login event?

Thanks.

What is the line of code you added in the account/login.php controller file?

Nothing ... original files are not modified. I just want to run updateCustomer function after the customer is logged in. It looks like updateCustomer is run but I couldn't get customer_id using $this->customer->getId()

function updateCustomer($route = '', $args = array(), $output = '') {
$this->log-_write($route);
$this->log-_write(print_r($args, true));
$this->log-_write($output);
$this->log-_write($this->customer->getId());
}
Should be changed for:

Code: Select all

function updateCustomer($route = '', $args = array(), $output = '') {
  $this->log->write($route);
  $this->log->write(print_r($args, true));
  $this->log->write($output);
  $this->log->write($this->customer->getId());
}
There are no underscores with methods in Opencart other than possible extensions. As for the $args not being passed, more information would need to be posted on your behalf since a single method does not demonstrate from which location you are actually launching the updateCustomer method.

Code: Select all

$this->log-_write
was a typo. My actual code is

Code: Select all

$this->log->write
. The problem is the function is supposed to run after customer logged in but for some reason I can't get $this->customer->getId() to give me customer_id.

The customer ID can be obtained once the page has been redirected and the customer logged in successfully. You can also verify with:

Code: Select all

if ($this->customer->isLogged()) {
    // Your argument here
}

My function is supposed to be run after the login event but it doesn't look like it is. Using opencart event system, how do I get customer ID after the customer login?

In an OCMod or VQMod file, you could always track this line from your system/library/cart/customer.php file,

find:

Code: Select all

private $address_id;
add below:

Code: Select all

private $registry;
Then, find:

Code: Select all

$this->session = $registry->get('session');
add below:

Code: Select all

$this->registry = $registry;
find in the login() method:

Code: Select all

$this->address_id = $customer_query->row['address_id'];
add below:

Code: Select all

$log = new Log('error.log');

$log->write($this->registry->get('request')->get['route']);
$log->write($this->customer_id);
This should already provide the results in the logs once the customer logs in.

Well I didn't want to use vqmod or ocmod. Using the event system should have worked, shouldn't it? Why wouldn't it work? Am I missing something or is this a bug?

This after event will never fire when a customer logs in because the last action on the controller is a redirect back to account/account after a successful login - so it never returns to the router to trigger the after event.

Unfortunately, I don't think there is any event you can hook into which would only fire once, you could potentially listen on the account/account route but would then need to have some state logic in your observer to only action your code once per login. which makes things complex.

What actions are you looking to take in your updateCustomer observer?

@straightlight and @daveyoi thanks for your reponses. I already found a workaround but it is just puzzling why it doesn't work. The "updateCustomer" function does get executed but not "after login" event. It ran sometime before the end of account/login function. I tried this event "catalog/controller/account/login/validate/after" but nothing happen.

The provided solution above with either OCMod and VQMod should work just fine. It will add the events through the logs real-time when someone logs in.

Yes, straightlight, it works really fine. Useful solution
