BackendPro 0.6.1

[eluser]Unknown[/eluser]
Hi,

i've update the BackendPro a bit and add a function to create the backend navigation via a xml file...


This helper search "module.xml" in the modules directory and list then the definied menu entries...

it add automatically the menu entries to the definied categories...

You must only add the defined resource to your system to see the entry

I have modified the menu template to my own design...
if you use another style, you must modify the menu template.

Have fun

Now the code.


1. Create a new helper
/system/application/helpers/backendmenu_helper.php

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/**
* Backend Menu Helper
*
* Create dynamic Backend Navigation
*
* @package         TutorialsMS
* @subpackage      Helpers
* @author          Marcus Reinhardt

*/

function getBackendNavigation()
{

    //get xml files from modules directory

    $CI         = & get_instance();
    $CI->load->library('parser');
    $xmlFiles   = getModulesConfigXml(FCPATH."modules");
    $menu['menu']       = Array();

    foreach($xmlFiles as $file)
    {
        
        $xmlObject              = simplexml_load_file($file);
        $data                   = xml2array($xmlObject);

        foreach ($data['navigation'] as $items)
        {
            
            if(isset($items['name']))
            {
                $menu['menu'][$data['category']][] = array(

                    'name'      => $items['name'],
                    'path'      => $items['path'],
                    'resource'  => $items['resource']

                );
            }
            else
            {
                foreach($items as $item)
                {
                  
                    $menu['menu'][$data['category']][] = array(

                        'name'      => $item['name'],
                        'path'      => $item['path'],
                        'resource'  => $item['resource']

                    );

                }


            }

        }
    }

//   echo "<pre>";
//   var_dump($menu);
//   echo "</pre>";

   return $CI->load->view($CI->config->item('backendpro_template_admin') . 'menu', $menu);

}

function xml2array($xml)
{
    $xmlArray = array();
    if(is_object($xml))
    {
        settype($xml,'array') ;
    }
    foreach ($xml as $key=>$value)
    {
        if(is_array($value) || is_object($value))
        {
            $xmlArray[$key] = xml2array($value);
            
        }
        else
        {  
            $xmlArray[$key] = $value;
        }
        
    }

    return $xmlArray;
}

//load xml files from modules
function getModulesConfigXml($root_dir, $all_data=array())
{
    // only include files with these extensions
    $allow_extensions = array("xml");
    // make any specific files you wish to be excluded
    $ignore_files = array();
    $ignore_regex = '/^_/';
    // skip these directories
    $ignore_dirs = array(".", "..", "controllers", "models", "helpers", "config", "views", "language", "libraries");

    // run through content of root directory
    $dir_content = scandir($root_dir);
    foreach($dir_content as $key => $content)
    {
      $path = $root_dir.'/'.$content;
      if(is_file($path) && is_readable($path))
      {
        // skip ignored files
        if(!in_array($content, $ignore_files))
        {
          if (preg_match($ignore_regex,$content) == 0)
          {
            $content_chunks = explode(".",$content);
            $ext = $content_chunks[count($content_chunks) - 1];
            // only include files with desired extensions
            if (in_array($ext, $allow_extensions))
            {
                // save file name with path
                $all_data[] = $path;
            }
          }
        }
      }
      // if content is a directory and readable, add path and name
      elseif(is_dir($path) && is_readable($path))
      {
        // skip any ignored dirs
        if(!in_array($content, $ignore_dirs))
        {
          // recursive callback to open new directory
          $all_data = getModulesConfigXml($path, $all_data);
        }
      }
    } // end foreach
    return $all_data;
} // end get_files()

2. Update the menu template
/system/application/views/admin/menu.php

Code:

<ul id="menu">
<li class="menu_link">&lt;?php print anchor('admin',$this->lang->line('backendpro_dashboard'))?&gt;</li>


&lt;?php foreach($menu as $items => $entries): ?&gt;

    &lt;?php if(check($items,NULL,FALSE)):?&gt;
    <li id="menu_&lt;?php echo $items;?&gt;"><b>&lt;?php echo $items;?&gt;</b>

        <ul>
            &lt;?php foreach($entries as $entry): ?&gt;

               &lt;?php if(check($entry['resource'],NULL,FALSE)):?&gt;<li class="menu_link">&lt;?php print anchor($entry['path'], $entry['name']); ?&gt;</li>&lt;?php endif; ?&gt;

            &lt;?php endforeach; ?&gt;
        </ul>

    </li>
    &lt;?php endif; ?&gt;

&lt;?php  endforeach;?&gt;

</ul>

3. Add the following code in
/system/application/libraries/Admin_Controller.php

Code:

$this->load->helper('backendmenu');

4. Create a new xml file in your module directory
/modules/<module_name>/module.xml

Code:

<?xml version="1.0" encoding="UTF-8"?>


<module>

    <modulename>auth</modulename>
    <category>System</category>
    <navigation>
                  
        <item>
            <name>Access Control</name>
            <path>auth/admin/access_control</path>
            <resource>Access Control</resource>
        </item>
        
        <item>
            <name>Members</name>
            <path>auth/admin/members</path>
            <resource>Members</resource>
        </item>
            

    </navigation>

</module>
