[quote]it works fine in IE, but not in FireFox[/quote]

Then I'd guess it's an html issue not a php issue.  Possibly a badly-coded form.

[almightyegg]

well, to be precise, you can login in FF but then you cant go to any pages...it just shows the login form again and says, please enter all the infomation....

[almightyegg]

Oh, and here is my form...

[code]
<center>
<fieldset><legend>Login</legend>
<table border=0 cellpadding=10><tr><td valign=center>
<form method=POST action=welcome.php name=form1>
Email:<br> <input type=text name=email><bR><br>
Password:<br> <input type=password name=password><br><br>
<input type=submit value=Login!>
</form>
</td></tr></table>
</fieldset>
</center>
[/code]

for - one just reading over your code - you give the user WAY too much info about the username password combo. Just say "Somehting is off with eiter your un or pw" if i were a hacker and seen that i had the correct username but not the right password, i could create a bot that would brute force its way in.

[AndyB]

Just so we can remove one possible problem, please use (something like) this as your log-in.  Halfway decent html never hurt anyone :)

[code]<center>
<fieldset><legend>Login</legend>
<table border="0" cellpadding="10"><tr><td valign="center">
<form method="post" action="welcome.php" name="form1">
Email:<br><input type="text" name="email"><br><br>
Password:<br><input type="password" name="password"><br><br>
<input type="submit" value="Login!">
</form>
</td></tr></table>
</fieldset>
</center>[/code]

[almightyegg]

didnt change anything  :-[

and yes i agree with emehrkay, it does have too much info....I will sort that out later...

[almightyegg]

right...this is very odd...I made no changes since yesterday, and now it is working  :-\ there must be something iffy going on  ???
