Problems with echo base_url

Question

I have already loaded the URL helper, I have set the base url in config, yet this code seems to gave me:

PHP Error was encountered

Severity: Error

Message: Call to undefined function base_url()

Filename: views/site_navigation.php

Line Number: 6

Here is line number six:

<li><a href="<?php echo base_url(); ?>/welcome">Home</a></li>

@tanaydin it's a CodeIgniter function - possibly a more relevant duplicate: http://stackoverflow.com/questions/6449386/base-url-function-not-working-in-codeigniter — scrowler, Apr 30 '15 at 00:59
Can you show your config file and your URL helper in the controller? From what I'm seeing looks good, but there could be something you missed causing it to error out. — David Gilliam, Apr 30 '15 at 01:01

This error means only one thing that you did not load the url helper correctly. Please follow the documentation and load it as specified from your current action or from the constructor of your controller.

When you need to use the base_url(); or config_item('base_url') or $this->config->item('base_url')

First example:

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

Or

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

Second Example:

Go to application / config / autoload.php

And add the url to here which I think is best for you.

$autoload['helper'] = array(
    'url',
    'file',
    'form',
    'text',
    'html',
    'date'
);

Now go to the application / config / config.php Find $config['base_url'] = '';

Enter your base url example http://www.example.com/ or http://localhost/project/

$config['base_url'] = 'http://www.example.com/'; Recommended include forward slash at end
$config['base_url'] = 'http://localhost/project/'; Recommended include forward slash at end

If you need to remove the index.php find htaccess examples here

Once all that is done

<li><a href="<?php echo base_url(); ?>">Home</a></li>

This will get you to the default home page

If you are using CI 2.0.0 (in line number 67)

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

or else if you are using CI 3.0.0 (in line number 91)

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

in addition

Assign these empty

$config['base_url'] = '';
$config['index_page'] = '';

base_url() is a function of the object config Try this: <li><a href="<?php echo $this->config->base_url(); ?>/welcome">Home</a></li>

This no longer gives me an error, however now when i click the links, it directs me to "this webpage is not available", I have checked the page source and the URL's in the links are as they should be. – KGdB Apr 30 '15 at 01:11
Make sure that the site_url variable in the config.php file is setted properly and then use $this->config->site_url(); – Sergio Vilchis Apr 30 '15 at 01:15
there is no variable in the config.php file for site url? – KGdB Apr 30 '15 at 01:16
shall i paste '$this->config->site_url(); ' into the config.php file or in the view? – KGdB Apr 30 '15 at 01:16
Sorry, my bad. Verify the $config['base_url'] variable – Sergio Vilchis Apr 30 '15 at 01:17
Paste it in the view

This brings up the right url in the address bar, however it still comes up with This web page is not available ERR_NAME_NOT_RESOLVED – KGdB Apr 30 '15 at 01:42

whereas if i just type the url without navigating through the link, the page works fine – KGdB Apr 30 '15 at 01:43

Check your

CI/system/helpers/url_helper.php

function base_url($uri = '', $protocol = NULL)
{
    return get_instance()->config->base_url($uri, $protocol);
}

you can set it on

CI/application/config/config.php

$config['base_url'] = ....

Open config.php $config['base_url']= "localhost/meusite to open Autoload library('url') or controller $this->load->library('url').
