fatal error: call to undefined function redirect()

Question

I am using mobiledetect for redirect mobile users to a specific page. But, when I'm writing this then I am getting the Fatal error for redirect(). Can anyone please let me know where and what I'm missing?

require_once 'Mobile_Detect.php';
$detect = new Mobile_Detect;
$deviceType = ($detect->isMobile() ? ($detect->isTablet() ? 'tablet' : 'phone') : 'computer');
$scriptVersion = $detect->getScriptVersion();

if ($detect->isMobile())
   redirect('iammobile.php');
else
   echo '<h1>I am Desktop</h1>';

`redirect()` is not a function. Error is fairly clear. Where are you creating this function? Do you actually want the [`header()`](http://uk3.php.net/manual/en/function.header.php) function? — naththedeveloper, Feb 17 '14 at 08:58

That means it couldn't find a function with a name `redirect` anywhere. Try using `header("Location:iammobile.php")` instead — asprin, Feb 17 '14 at 09:00

Try with header like

header("Location: iammobile.php");
die();

Hi, When I used like this: `if ($detect->isMobile())` `header("Location: iammobile.php");` Then it shows Internal Server Error – Md Mazedul Islam Khan Feb 17 '14 at 09:05
You need to give entire url of that file..while redirecting – GautamD31 Feb 17 '14 at 09:08
You meant Like this: `home/user/public_html/` ? – Md Mazedul Islam Khan Feb 17 '14 at 09:09
Still didn't work. I tried with `/home3/chew/public_html/fundmanagementsystem.com/demo/mobile/mobile.php` and `http://google.com` too – Md Mazedul Islam Khan Feb 17 '14 at 09:13

Check your server logs to see why it's showing internal server error – asprin Feb 17 '14 at 09:15

Use This function as construct

public function __construct() {
    parent::__construct();
    $this->load->helper('form');
    $this->load->helper('url');
}

Use this code as redirect

redirect(base_url().'login','refresh');

are you check this condition on `iammobile.php` if yes it will redirects in looping. – wild Feb 17 '14 at 09:38

Rather than redirect you should use the header function:

<?php
    header("Location: iammobile.php");
?>

You need add $autoload['helper'] = array('url', 'form'); in file autoload.php

Add construct function in your constructor then your redirect function will work.

function __construct(){ parent::__construct(); }
