Turn off right column in home page only

I gather that to turn off the right column in only the Home Page I insert the following code into the file tpl_main_page.php (in an override structure):-
if ($this_is_home_page) {
$flag_disable_right = true;
}
However I am unclear exactly where in the file this should be inserted.
Can someone please verify that I am correct, and clarify my confusion.

Rather try this:

Find the line (Around 42 / 43)

// the following IF statement can be duplicated/modified as needed to set additional flags
  if (in_array($current_page_base,explode(",",'list_pages_to_skip_all_right_sideboxes_on_here,separated_by_commas,and_no_spaces')) ) {
    $flag_disable_right = true;
  }

... and insert index where shown...

// the following IF statement can be duplicated/modified as needed to set additional flags
  if (in_array($current_page_base,explode(",",'index')) ) {
    $flag_disable_right = true;
  }

Later, if you want to, you can disable right column for more pages in this way.

:oops: Suggestion above does not work for home page only... Sorry...

Will get back to you.

Just paste it under this, as shown below:-

// the following IF statement can be duplicated/modified as needed to set additional flags
  if (in_array($current_page_base,explode(",",'list_pages_to_skip_all_right_sideboxes_on_here,separated_by_commas,and_no_spaces')) ) {
    $flag_disable_right = true;
  }

if ($this_is_home_page) {
$flag_disable_right = true;
}

Your code is correct and the file would go here:

includes/templates/YOUR_TEMPLATE/common/tpl_main_page.php

If you do not already have a 'common' dir. then you can create one.

Thanks to you both for the help.
Rob, I appreciate your confirmation that the code insert is correct, but you did not answer my main query regarding exactly where in the file the snippet should be inserted.

Thanks DB for the clarification.
