Config variables in templates

Question

Is there a way to access config variables from the config files via native EE tags so that I can display it in the templates ?

Or are there none that I have to right a plugin for it?

Answer 1

We can add variables to the config.php, instead of index.php, by this way:

global $assign_to_config;

if(!isset($assign_to_config['global_vars']))
$assign_to_config['global_vars'] = array();

So, I believe that you can set some config variables by this way:

$assign_to_config['global_vars']['cv_smtp_port'] = $config['smtp_port'] = '587';

On your templates, you'll have early parsed variables to work with:

{cv_smtp_port}

You can use this technique to get some data from global variables in early stages of parsing:

$assign_to_config['global_vars']['cv_site_url'] = $config['site_url'] = "http://domain.com";

{site_url} is parsed at the end of parsing stages, while {cv_site_url} will be parsed at the beginning.

I don't tested this, but I guess that edit edit config.php by the CP can destroy all of this. So, test this and maybe do not allow the users to access the config file editor.

I don't think so, the only method I'm aware of is using global variables in index.php as per the user contributed notes here - http://ellislab.com/expressionengine/user-guide/templates/globals/user_defined.html

I think otherwise you may need a plug-in though I'm not even sure that would work as the values in the DB which you could pull out with a plug-in are not necessarily going to mirror those defined in config.php.

Here's a really quick plugin that would do exactly what you need. Basically, create a folder in your add-ons directory called 'config_var', create a file pi.config_var.php and copy/paste the following in there

<?php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
$plugin_info = array(
    'pi_name'           => 'Config Vars',
    'pi_version'        => '1.0',
    'pi_author'         => 'Carl Crawley',
    'pi_author_url'     => 'http://www.madebyhippo.com',
    'pi_description'    => 'Returns Config var based on input',
    'pi_usage'          => config_var::usage()
);

class Config_var
{
    public $return_data = '';

    public function Config_var()
    {
        $this->EE =& get_instance();

        $var = $this->EE->TMPL->fetch_param('var');

        $this->return_data = $this->EE->config->item($var); 

        return; 
    }

    public function usage()
    {
        ob_start();
?>
Simply pass the variable you want to return in the tag {exp:config_var var="xxx"} and it will return the variable from the config.
<?php
        $buffer = ob_get_contents();

        ob_end_clean();

        return $buffer;
    }
    // END
}

Once you've done that, you can now simply called {exp:config_var var=""} passing in the config variable you want and it'll pull the data out onto the page.

While this is quite old thread, I don't see esy-to-use solution posted to it.

Config Variables Plugin is easy to use and provides access to all config variables (whether coming from config.php or saved in database) with template tag.
