[jacek]

What does mysql_error() tell you ?

[jaysus7]

Warning: mysql_result() [function.mysql-result]: Unable to jump to row 0 on MySQL result index 4 in /home/content/50/8811650/html/core/init/user.inc.php on line 13

why is that??


and to make a separate blog for each user, how would i go about doing so?...can you lead me in the right direction with some hints without obvious;y telling me how to do it or posting the code....like you guys say , can't learn by copying and pasting!!!

[jacek]

What does mysql_error() tell you ?

Your query is failing for some reason, adding the mysql_error() after it should tell you why.

[jaysus7]

nothing it says nothing this is why I'm confide it works for everything else when logged in it only shows when no one is logged in.

[jacek]

Ah okay, that must mean that the query is returning no results then.

Are you sure $user has the value you expect ? Maybe try running the query in phpmyadmin and see if you get anything back ?

[jaysus7]

this is correct no results????

now what??

this function has stopped my cookies.

also i get this for user avatar

Warning: imagejpeg(): supplied argument is not a valid Image resource in /home/content/50/8811650/html/core/init/user.inc.php on line 175

[jacek]

also i get this for user avatar

Warning: imagejpeg(): supplied argument is not a valid Image resource in /home/content/50/8811650/html/core/init/user.inc.php on line 175

One thing at a time

this is correct no results????

now what??

this function has stopped my cookies.

Does the variable going into the query have the value you expect it to have ? Try a

[syntax=php]var_dump($user);[/syntax]
and see what you get.

[jaysus7]

comes back NULL

honestly I'm sure i need the value 0 cuz thats where my kid is so i i believe so!!!

[jacek]

That probably means your $_SESSION['username'] is undefined in the init file.

Try setting error_reporting to E_ALL so that you see the undefined index messages. that will highlight any typos you made with the variable names.

[jaysus7]

This is correct but it would be undefined if i haven't sign in a user no? ... the error message doesn't show when a user is logged in only when i am logged out or logging in and setting my remember me cookies....

[jacek]

Exactly, this page has to only be available to logged in users.

[jaysus7]

but my init.inc and user.inc pages are part of my index.php so how do i work around that one...also won't set my cookies??

[jacek]

but my init.inc and user.inc pages are part of my index.php so how do i work around that one...

Those are not pages, the page is the file in the pages folder. The page is the thing that shows the blog posts. They have to be logged in tot he view that page.

also won't set my cookies??

Not sure that you mean by that ?

[jaysus7]

right but the login page needs the init and user inc files to log them in!

and for the cookies this is the error i get

Notice: Undefined index: username in /home/content/50/8811650/html/core/init.inc.php on line 25

and for the index page i get

[jacek]

right but the login page needs the init and user inc files to log them in!

Yeah that's fine, as long as you don't try to use any of the functions that assume the user is logged in.

All of these errors are actually caused by the first one, so make sure you are using the correct variable on that line. Or maybe you need to add a check to see if the user is logged in ?

[jaysus7]

ok the errors pop up at first initial load of the page...its gone when you log in ...however when you go to log in with or without cookies the headers show and the errors are still there!!!

[jacek]

The problem's all come from the fact that you are trying to use variables that don't have a value, there are some cases (like the user not being logged in) that will causes $_SESSION['username'] not to have a value. So you need to make sure it does before you use it

[syntax=php]if (isset($_SESSION['username'])){
// do stuff that needs $_SESSION['username'];
}[/syntax]

[jaysus7]

thats funny when i put islet it messed everything up you tell me to do it and it works ....go figure eh.

now that thats out of the way the uid variable is not working...meaning that the edit page doesn't edit, the user info doesn't show on the edit page, and the link to the logged in user does not work no more!!

what did i change to make it all not work.....i fix one problem and another happened lol love this job!!!
