Override callback function in Drupal7

Question

I am using blog module. I can access it using this URL: http://localhost/drupal/blog. I have put some posts.

In the blog content type, I have added a field such as posted date. When I open the same URL http://localhost/drupal/blog, blog posts are coming using ordering on submitted date.

Now I want that posts should be list out using order by newly added field "posted_date". I don't want to change default functionality defined in the blog.pages.inc page. please suggest!

Answer 1

Create this function in module_name.module file in the custom module.

Ex: sites/all/modules/custom/module_name/moduleName.module

/**
 * Implements hook_menu().
 */
function moduleName_menu() {
$items['blog'] = array(
    'title' => 'Blogs',
    'page callback' => 'blog_list',
    'access callback' => TRUE,
    'file' => 'page_name.inc',
    'type' => MENU_CALLBACK  
  );
}

Create a file moduleName.pages.inc and define callback function.

Exm: sites/all/modules/custom/moduleName/moduleName.pages.inc

function blog_list() {
   return t('welcome blog');
}

I hope it will work for you cheers!
