I am trying to build a simple custom CMS, but I\'m getting an error:

Answer 1

use global scope on your $con and put it inside your getPosts() function like so.

function getPosts() {
global $con;
$query = mysqli_query($con,"SELECT * FROM Blog");
while($row = mysqli_fetch_array($query))
    {
        echo "
";
        echo "
" . $row['Title'] . "
" . $row['SubHeading'];
        echo "
";
    }
}
