CodeIgniter - accessing $config variable in view

Pretty often I need to access $config variables in views. I know I can pass them from controller to load->view(). But it seems excessive to do it explicitly开发者_如何学Python.

Is there some way or trick to access $config variable from CI views without disturbing controllers with spare code?

$this->config->item() works fine.

For example, if the config file contains $config['foo'] = 'bar'; then $this->config->item('foo') == 'bar'

Also, the Common function config_item() works pretty much everywhere throughout the CodeIgniter instance. Controllers, models, views, libraries, helpers, hooks, whatever.

You can do something like that:

$ci = get_instance(); // CI_Loader instance
$ci->load->config('email');
echo $ci->config->item('name');

$this->config->item('config_var') did not work for my case.

I could only use the config_item('config_var'); to echo variables in the view

Your controller should collect all the information from databases, configs, etc. There are many good reasons to stick to this. One good reason is that this will allow you to change the source of that information quite easily and not have to make any changes to your views.

This is how I did it. In config.php

$config['HTML_TITLE'] = "SO TITLE test";

In applications/view/header.php (assuming html code)

<title><?=$this->config->item("HTML_TITLE");?> </title>

Whenever I need to access config variables I tend to use: $this->config->config['variable_name'];

echo $this->config->config['ur config file'] 

If your config file also come to picture you have to access like this for example I include an app.php in config folder I have a variable

$config['50001'] = "your  message"   

Now I want access in my controller or model .

Try following two cases one should work

case1:

$msg = $this->config->item('ur config file');

echo $msg['50001'];    //out put:  "your message";

case2:

 $msg = $this->config->item('50001');

 echo $msg;    //out put:  "your message"

$config['cricket'] = 'bat'; in config.php file

$this->config->item('cricket') use this in view

If you are trying to accessing config variable into controller than use

$this->config->item('{variable name which you define into config}');

If you are trying to accessing the config variable into outside the controller(helper/hooks) then use

$mms = get_instance();  
$mms->config->item('{variable which you define into config}');

Example, if you have:

$config['base_url'] = 'www.example.com'

set in your config.php then

echo base_url();

This works very well almost at every place.

This might work for the latest versions of codeigniter (4 and above).
