Depending on the argument passed in url go to specific content type I have a link "Add Details". suppose when I click on the Add Details, I will send arguments to the urls. such as in url "http://localhost/drupal/video" video will be my argument. When I click on "Add Details" link if argument is video then I want to go to "Video content type". 

When I click on "Add Details", if argument passed is "image" in url("https://localhost/drupal/image), Then I want to go to "image content type".

When I click on "Add Details" link depending on the argument passed in URL I want to go to specific Content type.

How to achieve this.

Any help is appreciated.
Use hook_menu in custom module to achieve this using below code !
Change the links of Add Details to "goto/video" means full url will be localhost/drupal/goto/video

function yourmodule_menu() {
    $menus['goto/%'] = array(
        'title' =&gt; 'Just Redirect',
        'page callback' =&gt; 'drupal_redirect_to_content_type',
        'page arguments' =&gt; array(1),
        'access arguments' =&gt; array('access content'),
        'type' =&gt; MENU_CALLBACK,
    );
    return $menus;
}

function drupal_redirect_to_content_type($type) {
  drupal_goto("admin/structure/types/manage/" . $type);
}


Otherwise,

Instead of above what you can do it directly give Add Details link to admin/structure/types/manage/ . $type instead of drupal/$type
