hi peeps i am having so much trouble..

 

i have created a form which takes values from the reg users database and the values are passed from a view users script. the scrip i am working on is designed so the user can change there details and then update there account... but my problem is that when i submit the form nothing happens and it just appiers as a blank screen.

 

i have checked that the database is working. and that is...

 

please help out a newbie as i am only learning..

 

thanks

Theres a fair bit of code in your post but straight away I see this section as a problem.

 

<?php // added to get the boards syntax highlight working.

$query = "SELECT user_id FROM users WHERE email='$e' AND user_id != $id";
	$result = mysql_query($query);
	if (mysql_num_rows($result) == 0) {

		// Make the query.
		$query = "UPDATE users SET first_name='$fn', last_name='$ln', email='$e' WHERE user_id=$id";
		$result = @mysql_query ($query); // Run the query.
		if (mysql_affected_rows() == 1) { // If it ran OK.

?>

 

Here you check if the user exists, if not you try and UPDATE there record. If they don't exist, you can't very well UPDATE the record because it doesn't exist.

i have another form which has all the details of the reg memeber with a edit and a delete option.

 

when i delete an reg user works fine.

 

when i click on the edit option it goes to the page. i change some details and then when i submit it nothing..

 

i am just not sure where to look
