Get the user information from your database, preferrably by using a model.
Call the model function from within your controller.
Then, let your controller output the data by loading a view.

Basic example

Model:
PHP Code:
public function get_user($id)
{
 
 $query $this->db->where('id',$id)->get('users');
 
 return $query->row();


Controller:
PHP Code:
public function show_user($id)
{
 
  $this->load->model('user_model');
 
  $data['record'] = $this->user_model->get_user($id);
 
  $this->load->view('user_detail',$data);


View:
Code:
<p><?= $record->id;?></p>
<p><?= $record->name;?></p>
<p><?= $record->pseudo;?></p>

Why would you need a foreach ... loop to handle multiple accounts, if your model returns only one account?
Besides that, right below the line with foreach, you are opening a form twice:
PHP Code:
<?= form_open() ?>
     <form role="form" action="#" method="post"> 
The first line is the form_open() function in the form helper, this creates the <form .. > tag for you.
The second line is opening another form!
Line 75 closes one of the forms, but the other one stays open.

The syntax
PHP Code:
<?php foreach ( ... as ... ) { ?>
...
<?php ?>

is difficult to read, especially if you have nested foreach or if {} structures in your view.
Try the alternative syntax:

PHP Code:
<?php foreach (... as ... ) : ?>
...
<?php endforeach; ?>
ah okay thanks for the form i have forget this   Big Grin  

and for the error i delete the foreach and i got this erros now  Sad :

and i do not edit the  User_model

Your error screenshot shows that you don't parse any value into the controller's User::account().
your '$id' doesn't have default value, so that error might be the expected result.
OH thanks it work great now Smile
