Trying to get property of non-object error

Hello all!

I got this error and need help fixing:

Severity: Notice

Message: Trying to get property of non-object
Filename: views/profile.php
Line Number: 475



Tried to var dump but didnt know where to place it. I feel its an issue with connecting to DB.

View issue line:

As you can see this is an MVC formatted code(Ive learned my lesson ) I just have this one issue. How to get it off if possible?

,
Mekaboo

PLEASE use code tags around code, so that your post doesn't go on forever. Many readers will tune out!
You might also notice that trying to bold the code is self-defeating.

Your question does not make clear which line in the view is the error triggering one.

I am going to guess that $user_data[0] is undefined, and not what you expect.

Why $user_data[0] ?
The function in your model has to return the details for 1 user. If you just need 1 record from a table, don't use $this-db->result(), but $this->db->row().
Then, you can address the fields inside the record like this:

PHP Code:

echo $user_data->profile_pic
