Re: PHP output fails from AJAX call

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The one thing i doubts whether program control reaches to
ajaxex.php.Access_log says it is executing ajaxex.php. I tried to check
whether my program flow reaches to ajaxex.php by adding below lines in
ajaxex.php :

//echo "Mysql Connected";

//echo "Value of users : $q";

before the select command but after clicking on Weekly Report nothing
happens :(

Seems debugging is very difficult than to fix. There is no error in
error_log as well.

Thanks
