Display user's data from database on their profile pages - drupal

Question

In Drupal 7, is it possible to show a result of a DB query on each users' respective profile page, in some table? I need to do this programmatically within my existing module. So the input to the query would be the ID of a user whose profile is currently being viewed.
Only to show the queried data - no administration, no edits, nothing else.
something along the lines of.. (image)
Also the block or field or whatever would make this possible needs to be configurable through the _permission() hook as to who can or cannot view it.
I thought since this is basically just a query with no extra custom stuff there would be an easy way via the Drupal API.

Answer 1

you can create custom block for that and view it in current user profile
/**
* Implements hook_block_info().
*/
function custom_block_block_info() {
$blocks = array();
$blocks['my_block'] = array(
'info' => t('My Custom Block'),
'status' => TRUE,
'region' => 'Content',
'visibility' => BLOCK_VISIBILITY_LISTED,
'pages' => 'user/*',
);
return $blocks;
}
/**
* Implements hook_block_view().
*/
function custom_block_view($delta = '')
{
// The $delta parameter tells us which block is being requested.
switch ($delta)
{
case 'my_block':
// Create your block content here
$block['subject'] = t('This is just a test block created programatically');
$block['content'] = _user_detail_list();
break;
}
return $block;
}
/**
* Implements costome code we want to print().
*/
function _user_detail_list(){
//enter your query and output in some variable
$value = "<p>User Detail</p>"
return $value;
}
Note :- Here profile is extended with new block

There will be some coding to get what you want, but if you just want style/show the data that's already available with the "user" object then #1 below will do it.
Easy way(#1):
1. Create a view and choose the "user" info that you need shown and give it a path. Then in your sub-theme use the correct template -see the code snippets.

other ways:
use the user-profile.tpl.php see
https://api.drupal.org/api/drupal/modules%21user%21user-profile.tpl.php/7.x
in your module, you need to call and reach out to the hook_user_view.

Here you fetch user profile data from database then follow it
function modulename_menu() {
$items['user-data'] = array(
'title' => 'User data',
'page callback' => 'user_data',
'access callback' => ('user_is_logged_in'),
'#type' => MENU_NORMAL_ITEM,
);
return $items;
}
function user_data(){
global $user;
$user_fields = user_load($user->uid);
$output = "" //return those $user_fields values into table using theme('table',header,rows)
return $output;
}
https://www.drupal.org/node/156863 (for create table view)
i.e
global $user;
$user_fields = user_load($user->uid);
$firstname = $user_fields->field_firstname['und']['0']['value'];
$lastname = $user_fields->field_lastname['und']['0']['value'];
