Widget plugin (intelligent view partials)

[eluser]wiredesignz[/eluser]
Plugins have been deprecated since CI 2.0.0

You could convert the widget plugin into a helper or library as needed.

Or you could extend the CI_Loader library with a plugin loader method.

Such as follows which is copied from CI1.7.2 but not tested in CI2.1.x or CI3.0

EDIT: Also note that the EXT constant has been deprecated now so you'll need to replace all occurrences of EXT in the widget plugin with '.php'

Code:

class MY_Loader extends CI_Loader {

public $_ci_plugins = array();

/**
  * Load Plugin
  *
  * This function loads the specified plugin.
  *
  * @access public
  * @param array
  * @return void
  */
function plugin($plugins = array())
{
  if ( ! is_array($plugins))
  {
   $plugins = array($plugins);
  }

  foreach ($plugins as $plugin)
  {
   $plugin = strtolower(str_replace('.php', '', str_replace('_pi', '', $plugin)).'_pi');  

   if (isset($this->_ci_plugins[$plugin]))
   {
    continue;
   }

   if (file_exists(APPPATH.'plugins/'.$plugin.'.php'))
   {
    include_once(APPPATH.'plugins/'.$plugin.'.php');
   }
   else
   {
    if (file_exists(BASEPATH.'plugins/'.$plugin.'.php'))
    {
     include_once(BASEPATH.'plugins/'.$plugin.'.php');
    }
    else
    {
     show_error('Unable to load the requested file: plugins/'.$plugin.'.php');
    }
   }
  
   $this->_ci_plugins[$plugin] = TRUE;
   log_message('debug', 'Plugin loaded: '.$plugin);
  }  
}
}
