Run another function in controller class - Background process - El Forum - 12-06-2007
[eluser]cinewbie81[/eluser]
Hi all,
In my "Main" Controller index function, i want to call the index() function from "SendSMS" controller class. How can i do it ?
I know it can be done using redirect("SendSMS") statement, but I don't want it to be this way. Instead, i want the SendSms index() function to be running as background process(using the '&' symbol). How can i do it ? Anyone ??
Thanks.
Code:
<?php
class Main extends Controller {
function index()
{
// I want to run mybackground_function() here from Runbackground controller
}
}
?>Code:
<?php
class SendSMS extends Controller {
function index()
{
// sending thousands of SMS here
}
}

try something like this (totally untested)
you use fsockopen to make a connection to the url, writing the data of the request, then just close the socket without reading the reply
Code:
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
log_message('error', 'Unable to connect to server');
return;
}
$request = "GET /SendSMS/index HTTP/1.1\r\n"
."Host: www.example.com\r\n"
."Connection: Close\r\n\r\n";
fwrite($fp, $request);
// normally now we would get the result like so
//$result = '';
//while (!feof($fp)) {
// $result .= fgets($fp, 128);
//}
fclose($fp);Run another function in controller class - Background process - El Forum - 12-07-2007

The way i would do this is to set up a cron task for the sendsms (class???) function where i would check in the database the messages that haven't been send already.
Background tasks are less recourse demanding using cron than php alternatives.

Instead of a background class you just write a function(s) and set up a cron task(s) to process the function.
Code:
class Main extends Controller {
function index()
{
// I want to run mybackground_function() here from Runbackground controller
}
function sendonesms()
{
}
function sendmultiplesms()
{
}
}I don't know how you are going to trigger when an sms has to be send but i guess you want it send when they click submit that's why you want to run the background script. Does it matter if it's send that instant or after a minute or two ,or three. Using a cron script that runs every minute you can control the flood of messages so it doesn't overload the sms server/service. But you are free to choose your own interval of course

Thanks.
But may i know what is cron task ? and how to setup a cron task to process those function ??
P/S: It's acceptable if the SMS send a minute later !!

put my code anywhere you want.
put it in a library maybe and then when you want the process to run call it
library/sms.php
Code:
<?php
if (!defined('BASEPATH')) exit('No direct script access allowed');
class sms {
function sms() {
}
function background() {
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
log_message('error', 'Unable to connect to server');
return;
}
$request = "GET /SendSMS/index HTTP/1.1\r\n"
."Host: www.example.com\r\n"
."Connection: Close\r\n\r\n";
fwrite($fp, $request);
fclose($fp);
} // background()
} // class smsthen when you want to send the sms dont go to another controller just use the library
Code:
class Main extends Controller {
function index()
{
$this->load->library('sms');
$this->sms->background();
}
}as I stated before I am not sure this will work but it is fairly quick to setup and worth a try

hi tonanbarbarian,
I need to use some of the CI built in function in function background(), for eg: this->db->query(), but inside the library it doesn't allow me to do so ...
