base_url() function not working in codeigniter

PhpCodeigniter

Php Problem Overview

In my web application using codeigniter. I am trying to use base_url() function but it shows empty results. I have also used autoload helper through autoload file, but then too it doesn't seem to work. Also I had defined base constants but all in vain.

<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title><?php echo $title; ?></title>        
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
        <link rel="stylesheet" href="<?php echo base_url();?>/css/template/default.css" type="text/css" />
        <script type="text/javascript">
            //<![CDATA[
            base_url = '<?= base_url();?>';
            //]]>
        </script>
    </head>

Php Solutions

Solution 1 - Php

In order to use base_url(), you must first have the URL Helper loaded. This can be done either in application/config/autoload.php (on or around line 67):

$autoload['helper'] = array('url');

Or, manually:

$this->load->helper('url');

Once it's loaded, be sure to keep in mind that base_url() doesn't implicitly print or echo out anything, rather it returns the value to be printed:

echo base_url();

Remember also that the value returned is the site's base url as provided in the config file. CodeIgniter will accomodate an empty value in the config file as well:

> If this (base_url) is not set then CodeIgniter will guess the protocol, domain and path to your installation. > > application/config/config.php, line 13

Solution 2 - Php

If you want to use base_url(), so we need to load url helper.

  1. By using autoload $autoload['helper'] = array('url');
  2. Or by manually load in controller or in view $this->load->helper('url');

Then you can user base_url() anywhere in controller or view.

Solution 3 - Php

First of all load URL helper. you can load in "config/autoload.php" file and add following code $autoload['helper'] = array('url');

or in controller add following code

$this->load->helper('url');

then go to config.php in cofig folder and set

$config['base_url'] = 'http://urlbaseurl.com/';

hope this will help thanks

Solution 4 - Php

Check if you have something configured inside the config file /application/config/config.php e.g.

$config['base_url']	= 'http://example.com/';

Solution 5 - Php

I think you haven't edited codeigniter files to enable base_url(). you try to assign it in url_helper.php you also can do the same config/autoload.php file. you can add this code in your autoload.php

$autoload['helper'] = array('url');

Than You will be able to ue base_url() like this

<link rel="stylesheet" href="<?php echo base_url();?>/css/template/default.css" type="text/css" />

Solution 6 - Php

If you don't want to use the url helper, you can get the same results by using the following variable:

$this->config->config['base_url']

It will return the base url for you with no extra steps required.

Solution 7 - Php

Load url helper in controller

$this->load->helper('url');

Solution 8 - Php

Anything if you use directly in the Codeigniter framework directly, like base_url(), uri_string(), or word_limiter(), All of these are coming from some sort of Helper function of framework.

While some of Helpers may be available globally to use just like log_message() which are extremely useful everywhere, rest of the Helpers are optional and use case varies application to application. base_url() is a function defined in url helper of the Framework.

You can learn more about helper in Codeigniter user guide's helper section.

You can use base_url() function once your current class have access to it, for which you needs to load it first.

$this->load->helper('url')

You can use this line anywhere in the application before using the base_url() function.

If you need to use it frequently, I will suggest adding this function in config/autoload.php in the autoload helpers section.

Also, make sure you have well defined base_url value in your config/config.php file.

This will be the first configuration you will see,

$config['base_url'] = 'http://yourdomain.com/';

You can check quickly by

echo base_url();

Question -I wanted to load my css file but it was not working even though i autoload and manual laod why ? i found the solution => here is my solution : application>config>config.php $config['base_url'] = 'http://localhost/CodeIgniter/';; //paste the link to base url

question explanation:

i had my bootstrap.min.css file inside assets/css folder where assets is root directory which i was created.But it was not working even though when i loaded ?

  1.           $autoload['helper'] = array('url');

  2.           $this->load->helper('url'); in my controllar then i go to my

Solution 10 - Php

I encountered with this issue spending couple of hours, however solved it in different ways. You can see, I have just created an assets folder outside application folder. Finally I linked my style sheet in the page header section. Folder structure are below images.

enter image description here enter image description here

Before action this you should include url helper file either in your controller class method/__constructor files or by in autoload.php file. Also change $config['base_url'] = 'http://yoursiteurl'; in the following file application/config/config.php

If you include it in controller class method/__constructor then it look like

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

or If you load in autoload file then it would looks like

$autoload['helper'] = array('url');

Finally, add your stylesheet file. You can link a style sheet by different ways, include it in your inside section

-><link rel="stylesheet" href="<?php echo base_url();?>assets/css/style.css" type="text/css" />

-> or

<?php

	$main = array(
	'href'       => 'assets/css/style.css',
	'rel'        => 'stylesheet',
	'type'       => 'text/css',
	'title'      => 'main stylesheet',
	'media'      => 'all',
	'index_page' => true
	);


echo link_tag($main); ?>

-> or

finally I get more reliable code cleaner concept. Just create a config file, named styles.php in you application/config/styles.php folder. Then add some links in styles.php file looks like below

<?php
 $config['style'] = array(
    'main' => array(
        'href'       => 'assets/css/style.css',
        'rel'        => 'stylesheet',
        'type'       => 'text/css',
        'title'      => 'main stylesheet',
        'media'      => 'all',
        'index_page' => true
    )
 );

?>

call/add this config to your controller class method looks like below

$this->config->load('styles');
$data['style'] = $this->config->config['style'];

Pass this data in your header template looks like below.

$this->load->view('templates/header', $data);

And finally add or link your css file looks like below.

<?php echo link_tag($style['main']); ?>

Solution 11 - Php

Apart from making sure you have set config/autoload.php:

$autoload['helper'] = array('url');

Change application/config/config.php from:

$config['base_url'] = 'http://example.com/';

Become a dynamic base url:

$config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https": "http");
$config['base_url'] .= "://".$_SERVER['HTTP_HOST'];
$config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);

And using the host from php to run it on local, below is just an example port.

php -S localhost:2000

Solution 12 - Php

This All Directly Access Function Will Be Loaded Through Helper Class Only.

Like URL, Security, File all Are Helpers and You can Also Load Custom Helpers.

config/autoload.php

$autoload['helper'] = array('url', 'file', 'authorization', 'custom');
