I'm quite new to WP, especially to wordpress plugins.
I'm writing plugin which validate posted form (frontpage).
My style that i did that task previous is:
1. after user submit the form, i check posted variables
2. if there are errors i redirect user back to the same
page, before that i set in session in which there are
3. code cheks if there are errors or something else to
show, and if is, it's shows
the problem starts with headers.
in the example above i used technique with ob_start(); and
ob_end_clean(); in index file, to prevent 'headers already
sent' error is displaying
but in wordpress it's a bit different ...
at first time my way to complete the task was:
then make function asd() which calls class and class is
displaying needed information
and in that case i can't use header('location: xxx), cause
headers are already sent ...
so i made all that in a different way:
my code get slug from wp options and compare it with
requested page slug
if both are equal - function is called to show my plugin
$plugin_call_slug = get_option('_slug');
$requested_uri = base_server('REQUEST_URI'); // ==
$requested_page = get_page_by_path( $requested_uri );
$requested_page = $requested_page->post_name;
if($requested_page == $plugin_call_slug)
and _function calls class, and that class make all what it
and all output is stored in variable $return and that
variable is stored in session variable $ss
and then we call the same function
only now function() is displaying only that variable from
session variable $ss which hold all output from class
$a = base_session('return');
THE QUESTION IS - IS THIS A +/- CORRECT WAY HOW TO MAKE
INTERNAL REDIRECTS, OR THERE IS OTHER LESS PAINFUL WAYS TO
MAKE THOSE REDIRECTS AND OUTPUT NEEDED CONTENT... ???
