How to send post value to two separate functions - php

Question

I have a form and a submit action routed to BaseController/FirstFunction, but i need to POST some of the sent values to the SecondFunction. So how can i send a POST value to other functions.
Like this example: FirstFunction has a input value with the name "$value". I want the SecondFunction to use this "$value".
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class BaseController extends CI_Controller{
public function __construct()
{
parent::__construct();
}
public function FirstFunction()
{
$value = "Test Value";
/*Insert etc.*/
}
public function SecondFunction()
{
$insertData = [
'product_id' => $value,
];
/*Insert etc.*/
}
}

Answer 1

Change you form action to controller/common function and you will get form data in both function FirstFunction() and SecondFunction() .
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class BaseController extends CI_Controller{
public function __construct()
{
parent::__construct();
}
public function common(){
$this->FirstFunction();
$this->SecondFunction();
}
public function FirstFunction()
{
echo '<pre>'; print_r($_POST);
}
public function SecondFunction()
{
echo '<pre>'; print_r($_POST);
}
}

No, you can not send post values to multiple functions. Instead you can do something like this:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class BaseController extends CI_Controller{
public function __construct()
{
parent::__construct();
}
public function FirstFunction()
{
$value = "Test Value";
$this->SecondFunction($value);
/*Insert etc.*/
}
public function SecondFunction($value)
{
$insertData = [
'product_id' => $value,
];
/*Insert etc.*/
}
}
