Codeigniter call one's Class method inside another Classe's method - php

Question

To be very specific - there is CRM system written in Codeigniter called Rise. I would like to make (automatically) an expense entry ( call save() method of an Expenses class ) each time someone logs in ( inside save_timelog() method of a Projects class ) time manually.
Expense Controller:
function save() {
validate_submitted_data(array(
"id" => "numeric",
"expense_date" => "required",
"category_id" => "required",
"amount" => "required"
));
$id = $this->input->post('id');
$target_path = get_setting("timeline_file_path");
$files_data = move_files_from_temp_dir_to_permanent_dir($target_path, "expense");
$has_new_files = count(unserialize($files_data));
$data = array(
"expense_date" => $this->input->post('expense_date'),
"title" => $this->input->post('title'),
"description" => $this->input->post('description'),
"category_id" => $this->input->post('category_id'),
"amount" => unformat_currency($this->input->post('amount')),
"project_id" => $this->input->post('expense_project_id'),
"user_id" => $this->input->post('expense_user_id'),
"files" => $files_data
);
<.. ETC. CHECKING FILES ..>
$save_id = $this->Expenses_model->save($data, $id);
if ($save_id) {
echo json_encode(array("success" => true, "data" => $this->_row_data($save_id), 'id' => $save_id, 'message' => lang('record_saved')));
} else {
echo json_encode(array("success" => false, 'message' => lang('error_occurred')));
}
}
Projects Controller:
function save_timelog() {
$this->access_only_team_members();
$id = $this->input->post('id');
$start_time = $this->input->post('start_time');
$end_time = $this->input->post('end_time');
$note = $this->input->post("note");
$task_id = $this->input->post("task_id");
if (get_setting("time_format") != "24_hours") {
$start_time = convert_time_to_24hours_format($start_time);
$end_time = convert_time_to_24hours_format($end_time);
}
$start_date_time = $this->input->post('start_date') . " " . $start_time;
$end_date_time = $this->input->post('end_date') . " " . $end_time;
$start_date_time = convert_date_local_to_utc($start_date_time);
$end_date_time = convert_date_local_to_utc($end_date_time);
$data = array(
"project_id" => $this->input->post('project_id'),
"start_time" => $start_date_time,
"end_time" => $end_date_time,
"note" => $note ? $note : "",
"task_id" => $task_id ? $task_id : 0,
);
if (!$id) {
//insert mode
$data["user_id"] = $this->input->post('user_id') ? $this->input->post('user_id') : $this->login_user->id;
} else {
//edit mode
//check edit permission
$this->check_timelog_updte_permission($id);
}
$save_id = $this->Timesheets_model->save($data, $id);
if ($save_id) {
echo json_encode(array("success" => true, "data" => $this->_timesheet_row_data($save_id), 'id' => $save_id, 'message' => lang('record_saved')));
} else {
echo json_encode(array("success" => false, 'message' => lang('error_occurred')));
}
}
So now what I'm trying to do is inside Projects controller, save_timelog() method just below these lines:
<...>
if (!$id) {
//insert mode
$data["user_id"] = $this->input->post('user_id') ? $this->input->post('user_id') : $this->login_user->id;
} else {
//edit mode
//check edit permission
$this->check_timelog_updte_permission($id);
}
/* CREATING A SAMPLE ARRAY WITH STATIC DATA FOR AN EXAMPLE EXPENSE ENTRY */
$a = array(
"expense_date" => '2018-03-13',
"title" => 'Cat Food',
"description" => 'Sheba, Felix, KiteKat',
"category_id" => '85',
"amount" => '500',
"project_id" => '84',
"user_id" => '10',
"files" => $files_data
);
/* TRYING TO SAVE/SEND EXAMPLE ARRAY TO Expenses Class save() method (?) */
$b = $this->Expenses_model->save($a);
/* RESULT (?) */
$save_id = $this->Timesheets_model->save($data, $id);
if ($save_id) {
echo json_encode(
array(
array(
"success" => true,
"data" => $this->_timesheet_row_data($save_id),
'id' => $save_id,
'message' => lang('record_saved')
),
array(
"success" => true,
"data" => _row_data($b),
'id' => $save_id,
'message' => lang('record_saved')
)
)
);
} else {
echo json_encode(array("success" => false, 'message' => lang('error_occurred')));
}
<.. Closing save_timelog() method ..>
However it surely doesn't work and all I get is "POST http://rise.test/index.php/projects/save_timelog 500 (Internal Server Error)".
I also load Expenses model and Expenses categories model in Projects _construct():
Projects Controller:
public function __construct() {
parent::__construct();
$this->load->model("Project_settings_model");
$this->load->model("Expense_categories_model");
$this->load->model("Expenses_model");
}
I also contacted developers of Rise with following question/answer:
Me:
In Projects controller save_timelog() method I just want to call
Expenses controller save() method, and if save_timelog() is successful
I would like to save an Expense ( $this->Expenses_model->save($data,
$id); ) with appropriate data. Could be static values for now for
$data array in save() method - just to find out it's working.
Rise Devs:
Hi, You are doing almost right. Just remove the 2nd parameter $id. It
should be used only for update. $this->Expenses_model->save($data)
Would really appreciate any help and directions! Thanks.
