Passing a variable through function - php

Question

When I submit my form on my main index I am trying to pass a variable call $store_id to a function on same controller called do_upload_image($store_id)
I am trying to be able to get the last id that was inserted in my store table.
It works fine when loading another model function $this->example_model->add($store_id); but not when doing it on another function on same controller.
Error Output
Column 'store_id' cannot be null
INSERT INTO `setting` (`store_id`, `group`, `key`, `value`) VALUES (NULL, 'config', 'config_image', 'flagnz.png')
Like so
$store_id = $this->model_store_add->add_store(); // this way should let me get id that was inserted.
$this->do_upload_image($store_id);
How am I able to get the $store_id to pass through another function on same controller? I have a model which trying to pass the store id to on do_upload_image

I have narrowed down my own problem. I need to pass the store id a second time as a if statement and now all works
I just removed the resize function for testing to see if that was issue but now no why. Also need to add return true below for callback function.
public function do_upload_image($store_id) {
$config['upload_path'] = './image/upload/';
$config['allowed_types'] = $this->settings->get('config_file_ext_allowed');
$config['max_size'] = $this->settings->get('config_file_max_size');
$config['overwrite'] = $this->settings->get('config_file_overwrite');
$config['max_width'] = '*';
$config['max_height'] = '*';
$this->load->library('upload', $config);
$this->upload->initialize($config);
if ($this->upload->do_upload('config_image')) {
if ($store_id) {
$this->model_store_add->add_config_image($store_id, $this->upload->data());
}
return true;
} else {
return false;
}
}
