Thank you for your reply.
I wasnt totally honest with you :)
My somefile.php is included in index.php?kom=somefile.
At the end of index.php file I have echo $htmlOutput function and in
somefile.php I append HTML to global $htmlOutput variable. At the end
it gets echoed by index.php
So, simplified, my somefile.php looks like this:
switch($task)
{
case ajaxcheck:
//Check if enetred value ($POST[name]) already exists in DB. If so
put $msg=1 or $msg=0 and echo it
fAjaxCheck();
break;
case normalcheck:
fNormalCheck();
break;
}
When I use this jQuery code:
$.post(
"index.php?kom=somefile&task=ajaxcheck\",
{ime: $(\"#ime\").val()},
function(data){
alert(data);
});
as a result I get much more than $msg variable
I've put exit(); at the end of fAjaxCheck(); so that echo $htmlOutput
doesn't run (at the end on index.php). It works fine if I approach to
URL (index.php?kom=somefile&task=ajaxcheck) directly. I get my $msg
value printed without any other HTML, but if I go over jQuery POST
call I get bunch of HTML tags back.
Sorry if Im being boring with this, cause I know I could create
separate file, but I would like to solve this this way because I have
included classese for DB, inputFiltering in index.php etc.
Thank you ver, very much
