CI goes crazy with iframes

Severity: Notice

Message: Trying to get the property 'section' of non-object

Filename: models/CourseModel.php

Line Number: 47

Don't you see here that there is an issue

Hi thanks for the reply.

My issue is that if I have this code:

Code:

<section>
            CodeIgniter 
            <h2>It really is</h2>
    </section>

it works as expected.

As soon as I change this to:

Code:

<section>
            CodeIgniter 
            <iframe src="https://programiz.pro" title="programiz pro website" height="500" width="500" ></iframe>
    </section>

CodeIgniter throws up the error messages.

Why would it even check/run my data model when all I am doing is inserting HTML code?

The data model code is working fine elsewhere in my project so there is no issue with that.

Thanks
