Only one user can open admin.ctp file - php

Question

I want to do a page, and this page can open only one user. I want to do something like this: If user id = 1 then its opening else its throwing error.
I already tried this :
if (in_array($this->action, array('controller' => 'users', 'action' => 'admin'))) {
$postId = (int) $this->request->params['pass'][0];
if ($this->User->isOwnedBy($postId, $users['id'] = 1)) {
return true;
}else{echo "You are not admin!";}
}
Then I thinked, maybe this is a little bit easier ?
public function admin($id = null) {
$this->User->id = $id;
if ($id == 1) {
echo 'You are admin';
}
else {
throw new NotFoundException(__('You are not admin !'));
}
}
But its not working, How I get this user id in to this if. This second solution throwing only this error, but I dont want it, I want access if user id is 1.
Here is users picture
Thank you for any clue or solution.

Answer 1

Try this-
public function admin($id = null) {
$currentUserId = $this->Auth->user(id);
//$isAdmin = $this->User->hasAny(
//array('User.id' => $currentUserId)
//);
//if ($isAdmin) {
if ($currentUserId == 1)
echo 'You are admin';
} else {
throw new NotFoundException(__('You are not admin !'));
}
}
For logged in users.

Answer 2

The recommended approach for getting logged in user data is via the AuthComponent itself:
// in any controller
$userId = $this->Auth->user('id');
See Accessing the logged in userAccessing the logged in user in the Auth section of the CakePHP Book.

Better Option:-
use role id for admins, this will help you for multiple admins. and give negative id to admin:-
like add role_id column in user table and give value to -1
public function admin($id = null) {
$role = $this->Session->read('Auth.User.role_id');
if ($role < 0)
echo 'You are admin';
} else {
throw new NotFoundException(__('You are not admin !'));
}
}

Answer 4

so you want to check if the user ID is 1 ??
//Fetch the user informations from database and stock it into $user
if(is_admin($user[id])){
echo 'You are admin';
}
else{
echo 'You are not admin';
}
function is_admin($id = NULL){
if($id == 1){
return true;
}
else{
return false;
}
}
tell me if I misunderstood
Edit :
According to our chat, try this :
//Fetch the ID of the user and stock it in $user_id
if($user_id == 1){
echo 'You are admin';
}
else{
echo 'You are not admin';
}
