I was editing the Hellow world plugin as a template, and basically instead of writing hello world, I want it to write a variable, $i so I defined $i=1;

And then I edited the line in the post template so it wrote $i, but instead of echoing the number "1", it just echoes nothing.

Here is the edited file, with the two lines which are significant highlighted in red.

This isn't general MyBB Support /moving

The $i variable you are defining has to be defined inside the function where you're going to use it. If it can't be defined inside the function you need to either pass it to the function or declare it as a global variable in the start of the function. Also you need to return the contents of $post at the end of your function.

So you can do either of these

function hello_world_postbit($post)
{
$i=1;
$post['message'] = "<strong>$i</strong><br /><br />{$post['message']}";
return $post;
}

OR

function hello_world_postbit($post)
{
global $i;
$post['message'] = "<strong>$i</strong><br /><br />{$post['message']}";
return $post;
}
