There are two things I would do here... First, if you are getting a blank page, that seems to me to be an indication of a PHP error of some kind, but you most likely have PHP Errors turned off. To enable them either add this to the top of your login.php code, or change the PHP.ini file itself (change the values of "error_reporting" and "display_errors")

 

ini_set('display_errors',1); 
error_reporting(E_ALL);

My guess is that the issue you are having in the login.php file involves line 19:

 

$count = mysql_fetch_array($result) or die(mysql_error());

You may need to go about it like this instead:

 

$count = mysql_num_rows(mysql_query($result));

Still am facing same problem........

in login.php

 

$result = mysql_query(' SELECT * FROM admin ')

or die(mysql_error()); //working well

 

but my duty is to verity username and password(i,e matching user entered and database entry)if i write like this

$result = mysql_query(' SELECT * FROM admin WHERE username = "$myusername" AND password = "$mypassword" ')

or die(mysql_error());

 

am getting blank page

so this part giving troble or unable to parse (where username = "$myusername" and password = "$mypassword")

whats your view please assist me to rectify this........one more questions is it not possibe to use variabe inside mysql_query function as i did above?

 

kindly reply soon..............
