PHP returning object echoing out the values

Question

I am working with codeigniter ona PHP project at the moment, and one the libraries I am using returns an object of database results, that looks like this,

    stdClass Object
(
    [user_id] => 2
    [firstname] => John
    [surname] => Doe
    [email] => [email protected]
    [password] => 9d210a03bed920971fefab01b8f84a27
    [postcode] => W1 5ST
    [date_registered] => 2021-04-11 10:56:47
    [last_logged_in] => 2011-05-04 11:56:03
    [user_type_id] => 2
)

I am then trying to echo the values using the follow code, I sending user to my view by doing the following,

$data['users'] = $this->users_model->get_by($this->session->userdata('user_id');
$this->load->view('view', $data);

Then in my view I am doing the following,

echo $users->firstname;

However I get the following error at the top of my page,

A PHP Error was encountered

Severity: 4096

Message: Object of class stdClass could not be converted to string

Filename: libraries/Parser.php

Line Number: 63

How can I resolve this? Without changing how the database results are returned ideally.

"$data['users']" and "echo $user->firstname;" doesn't match. Just a misspell or is it the problem? — rzetterberg

You're assigning to users yet accessing user. Is that a typo? — JohnP

You cannot echo an object directly. create a method __toString() or serialize the object before echoing.

You're on the right track. A few things.

You're missing a closing ) in this line.

$data['users'] = $this->users_model->get_by($this->session->userdata('user_id'));

Also, It's hard to know what is being returned by your users model. Can you provide the code for $this->users_model->get_by()? That's where your problem will be.

Make sure you have your db query returning the object as you expect. You may need to add ->row() .

maybe it's because you're sending a variable called "users" to your view.. but in your view you call the variable $user and not $users

if not... the doc on views says:

Note: If you use an object, the class variables will be turned into array elements.

Good Luck!

For Codeigniter, you need to call $users->result(), $users->result_array(), $users->row() or $users->row_array() to access the DB result object data

http://codeigniter.com/user_guide/database/results.html

Assuming a single row is returned:

$data['users'] = $this->users_model->get_by($this->session->userdata('user_id');
$data['users'] = $data['users']->row();
$this->load->view('view', $data);
