[jQuery] jquery ajax problem
Hello everyone, I think Ill go go nuts!
I already posted something about problem Im facing with but I didn't
get the right answer so Ill try again by expaining my problem further.
My PHP website is organised in following manner:
MAin file is index.php and it includes other files. So, my
"components" are included by setting URL for example index.php?
kom=gallery. Everything in gallery
file (and all others) is printed into global variable $htmlOutput.=
and is echoed at the end of execution of index.php.
Gallery file, for example, runs switch($_POST[task]) and calls
different functions depending on value of ($_POST[task].
One function outputs HTML form where you can input username. I want to
check if username is already taken by querying my database. Normal
check would be by
pressing submit button but I want ajax to check availability and to
output message. For ajax check I've set a function fAjaxCheck() that
is triggered by
$_POST[task] = ajaxCheck. That function looks like this
ajaxCheck()
{
//Find if DB has that us ername
//if database returns so mething it means tahat usuername is already
taken
if(empty($result))
{
//Username taken
echo "no";
exit;
}
else
{
//Username ok
echo "yes";
exit;
}
}
I get my index php page html as a result!!!
This is jquery Im using:
$.post(\"index.php?kom=gallery\",
{
task:'is_username_taken',username: $('#username').val()},
function(data){
alert(data);
})
I can't understand why do I keep getting this result. exit() at the
and of if/else should stop script from working and my $htmlOutput
variable at the end of index.php sholud never be echoed.
Do you have any idea how to solve this? Why do I get all that html
when I shold be geting only things from my ajaxCheck() function, thing
I explicitly echo!?
Thank you and sory for the trouble...
