Codeigniter how to properly use base_url? - php

I am having a little trouble with base_url in codeigniter, let's say if I don't set my $config['base_url'] in the config/config.php file, calling base_url will produce [::1], this is not what I want, I want it to return localhost, so I set $config['base_url'] = 'localhost', yup it return localhost/bla/bla
when accessed locally, HOWEVER if I access my project remotely from another computer, it DOES keep returning 'localhost' too while what I want is to return the base_url as in the ip address of the server (i.e 192.168.1.8 etc).
I am very sure CI team has thought this through and has a special solution or parameter in the base_url however I wasn't able to find it or I am not searching enough. Anyway thanks in advance.

You can assign base_url dynamically using host
$config['base_url'] = 'http://'.$_SERVER['HTTP_HOST'].'/';

To use base_url(), you have to load the URL Helper first
$this->load->helper('url');
Or you can autoload it by changing application/config/autoload.php
Or just use
$this->config->base_url();
Same applies to site_url().
and use like this
<link rel="stylesheet" href="<?php echo base_url(); ?>css/default.css" type="text/css" />
you can follow this url

Codeigniter bootstrap load only on index.php page

I'm loading bootstrap this way on my view page :
<link rel="stylesheet" href="<? echo base_url('assets/css/bootstrap.min.css')?>">
autoload: $autoload['helper'] = array('url');
configs: $config['base_url'] = 'http://localhost/helloby/';
Below is the path of the controller:
http://localhost/helloby/index.php/login/home
But when I copy the same code at welcome_message view bootstrap loads normally. I don't know why it's happening.
Try using site_url() instead of base_url()
base_url returns the url without index.php
Check if you are loading the bootstrap css in every view, you cant just load it in one view and expect that all other views know about it.
Common way of doing things like this is to create header and footer files that are shared between all views.
I solved the problem, I was reading an e-book of best practice of Codeigniter and the call of bootstrap was a little bit different.
This way : href="<?=base_url('/assets/css/bootstrap.min.css')?>
and working fine!

how to remove codeigniter functions from base url when routing

I routed my controller function and suddenly the function name is added to base URL, how can I remove this?
$route['editblog/(:num)']='Code/editblog/$1';
Then all of the sudden edit blogs are added to base URL and my external files are showing an error.
<script src="assests/vendor/slick/slick.min.js">
It shows:
<script src="editblog/assests/vendor/slick/slick.min.js">
Please help me, help will be highly appreciated!
You need to verify 1 things:
application/config.php $config['base_url'] = 'application/path/'; like http://example.com/ or http://localhost/applicationName/
Now you should use urls like
base_url('assets/js/filename/js');
base_url('controller/action/parameters');
In this way, it will generate correct urls.
You should change your URL's to:
<script src="<?php echo base_url('assests/vendor/slick/slick.min.js'); ?>">
Actually base_url is set in your applications/config.php file. -> config['base_url']. It MUST include trailing slash
in your config file:
$config['base_url'] = 'http://test.com';
when you call out the base_url(). You can use this :
<script src="<?= base_url().'/assests/vendor/slick/slick.min.js'; ?>">

What is better? Using 'base_url()' or './'?

I have been using CodeIgniter Framework for some months.
In views, I usually include external css and js with base_url(), just like this:
<link href="<?php echo base_url() ?>assets/css/custom.css" rel="stylesheet">
But someone tells me that using ./ also works too. And that's true.
So, what is better ( in security )?
base_url() is a better choice to use.
There isn't a cost difference using a relative or complete url, and this way you know it will point to the right spot.
It's a better habit to be in, and you can pass URL parameters to it and keep code neat.
base_url() is just a helper (URL helper in CI). Some people just find it easier to use, so I don't see any added security by using base_url().
In case of ease of use, I see so many people use it like
<?php echo base_url()."controller/function";?>
while actually you can use it like
<?php echo base_url("controller/function");?>
You can used either, but its a good practice in Codeigniter to use base_url().
you can use use ./ instead of base_url(). ./ is the root directory of your codeIgniter installation and it will get that bath in most cases that are same as base_url(), but base_url() is best practice to use because in some server ./ does not work or some other issue.

base_url() function not working in codeigniter

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>
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
If you want to use base_url(), so we need to load url helper.
By using autoload $autoload['helper'] = array('url');
Or by manually load in controller or in view $this->load->helper('url');
Then you can user base_url() anywhere in controller or view.
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
Check if you have something configured inside the config file /application/config/config.php e.g.
$config['base_url'] = 'http://example.com/';
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" />
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
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.
Load url helper in controller
$this->load->helper('url');
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
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.
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']); ?>
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');

CodeIgniter: How do I include a .js file in view?

Where and how do I include .js files in Views in CodeIgniter?
I have tried this:
<script type="text/javascript" src="system/application/libraries/jquery.js"></script>
As I figured that the index.php is the one that is loading the views, so I'm guessing that every time a page is loaded the current dir path is at root because index.php is located at root. Is this true?
The above line doesn't so I am doing something wrong. I have a CodeIgniter project. The path is like this:
localhost/CodeIgniter/system/application
so which path should I use to include my jquery.js file which is located in
localhost/CodeIgniter/system/application/libraries
when I want to load the jquery.js file in a View located here:
localhost/codeIgniter/system/application/views/till_view.php
There is a lesser-known solution that works really well with clean syntax and much more portability than hard-coding URL's or relative files.
<base href="<?=base_url();?>">
<img src="images/logo.gif" alt="Logo" />
Read more about how, what, why on my article "Asset handling in CodeIgniter with the BASE tag".
It's not the "index.php" file that is the view. The view is whatever is loaded in your controller when you do a
$this->load->view("viewname");
The file "viewname.php" can then include the .js files, just as a normal .html (or .php) file would:
<script src="/url/to/javascript.js" />
You may want to create a default view or a "header" view that includes some or all of the (common) .js files for your project.

First question:
It depends if you use absolute or relative urls.
Absolute urls go from the root of your domain. Relative urls are loaded relative from the current directory (including the url segments).
Second question:
It's best to use an absolute URL. Because of the pretty urls, it's not recommended to use relative urls.
The easiest way is to use the url helper and then use the site url function like this:
$this->load->helper('url');
echo site_url('system/application/libraries/jquery.js');
Ps. I recommend to put things like javascript and images outside of the CodeIgniter directory.
base_url() always works fine for me
Here is a solution specifically relevant to the OP which I didn't think anyone else provided.
<script type="text/javascript" src="<?= base_url() ?>libraries/jquery.js"></script>
So, base_url() will provide a path direct to the root of your site.
<script type="text/javascript" src="<?php base_url() ?>libraries/jquery.js"></script>
base_url() will provide the url of the site
The easiest way you can directly access the file:
<img src="http://localhost/ci/you_dir/your_img/your_image.png" />
where ci is for codeigniter.
