Login help

hilln2

problem with login!

have login working but doesnt redirect user to homepage!

i.e code is like:

if (mysql_num_rows($result))
// redirect to members page

else
echo "failed login";

what code do I put in there: I have tried using a link, i.e <a href "blah"> </a> but it didnt work.

Bear in mind this is a .inc file!!!

Any help is appreciated

Gargouil

simply use the header() function

note that you should not have any html before calling header of you will have an error see php documentation

try this

if (mysql_num_rows($result))
{
header("Location: logged.php");
}
else
{
echo "failed login";
}

thanx 4swift reply

I was trying that, but it wasnt working!
Im getting error saying:

Warning: Cannot add header information - headers already sent by (output started at /savadata.php:2) in /getresult.inc on line 11

in savadat.php I had if loop:

if($A01 != 0)
{
header("Location: addauser.php");
exit;
}

even when I commented this out, I still got the error!
Any ideas

Gargouil

Ok
This is because you should have text before you call header

here are exemple that DONT WORK:

your document should start with <? and don't have any echo, print, or anything else that output charactere to your page

do you login treatment in the top of your document before it load anything.

hilln2

It still seems to not work! Im not exactly sure what you're saying!
It won't redirect to meembers homepage when its a successful login.
This is the code for that page!
Any help would be brilliant.
Really stuck!

<?php

if (isset($password)) // if a the password is set then the form has been submitted on login.php page
{
include("connect2db.php");
$qstr = "SELECT * from members where username = '$username' and password = '$password'";
$result = mysql_query($qstr);
// check login info is correct
if (mysql_num_rows($result))
// echo "<Center>Successful Login</Center>";
{
header("Location: MembersArea.html");
}

else {
echo "<Center>Failed Login</Center>";
}
mysql_close();
}
else echo "<Center>No login attempted</Center>";
?>😕

Gargouil

Can you paste me your actual error message...

This will give me some additionnal explanation...

hilln2

Its

Warning: Cannot add header information - headers already sent by (output started at /header.inc:9) in /getresult.inc on line 12

That happens when I put it a correct username and password!

Gargouil

ok this simple meen that you should have some include before your header

in this include you have output to browser
do you test at the top of document before anything

if you have a good user he will be redirect... else the page will continue to load

if this still continue not working include attachement in your reply i will check you complete page code

hilln2

sorry! im not exactly sure what you are saying! do u mean have an include that has a link in it? this is wat i wrote? doesn't work! im new at this so maybe i totally didn't understand you!

if (mysql_num_rows($result))
// echo "<Center>Successful Login</Center>";
{
include("loggedin.html");
header("Location: MembersArea.html");
}

loggedin.html

<html>
<HEAD>
<TITLE>Logged in </TITLE>
</HEAD>

<BODY>

</BODY>
</HTML>

Gargouil

don'T understand what you are trying to do

why include a html file if immediately after you redirect elsewhere ?

hilln2

because the header wouldn't work! keep getting errors! i misunderstood wat you were saying! sorry! could u try and explain again to me wat i should do! sorry!
😕

Gargouil

we start over

include("loggedin.html");
header("Location: MembersArea.html");

this two line do the same thing, the first include a document code in the current page then header redirect the page to the specified document.

so you are trying to do the same thing two time but in different way.

now.. simply delete the include line

only keep header(...)

the include is the reason why your header don't work..
your include print html code to the document then after you call header

anyway... only keep the header line and try...

hilln2

Ok.. i took out the include! we're back to the start..
i get the error

Warning: Cannot add header information - headers already sent by (output started at /header.inc:9) in /getresult.inc on line 13

Gargouil

you still have code output before the call of your header(...);

what are header.inc and getresult.inc ?

they are called probably by a include ".." before in the code

now take your code then put your validation at the top of your document, check if the member is valide immediately before anyting before header, before logo before <html> basile

at the top!

your should have nothing before header(...)
have you a local server ? give me the url or send it to gargouil2003@hotmail.com then i will check what wrong directly

i won't see your php code but i will be ble to say what make that the header does error

hilln2

getresult.inc is

<?php

else {
echo "<Center>Failed Login</Center>";
}
mysql_close();
}
else echo "<Center>No login attempted</Center>";
?>

the header.inc is

<html>

<head>
<title>Register</title>
</head>

i will send all da code to you at ur email address with the url! maybe dat will help as i am of no use.. sorry!

Gargouil

ok
this give me this
Warning: Cannot add header information - headers already sent by (output started at /connect2db.php:13) in /getresult.inc on line 13

this meen that in your connect2db.php at line 13 you have some text sent to browser but this is not always right...

so.. i have check the source code of the web page and it "seems have no html code" but i already have seen this error before

this is a simple carriage return...
probably that your file should like this

--- start of file ---
<< you probably have a carriage return this is considered as html output... 🙂
<?
code..
?>

and your file should like this

--- start of file ---
<?
code...
?>

hilln2

im sorry...
i never uploaded the new code..
u were getting old error!!! the error with the code you have is..

Warning: Cannot add header information - headers already sent by (output started at /users/cais3/shicke-cais3/public_html/Footie/Php1/login.php:2) in /getresult.inc on line 13
