I have a login page i made. I want when the user clicks summit the data to be processed and a return value given to the original page if the pasword or username are wrong, so, this is pre_reg.php
<code><FORM action=register.php method=post>
<INPUT class=table_text
name=username>
<INPUT class=table_text
type=password name=password>
<INPUT type=image height=20
width=94
src="btn_register_green.gif"
align=top value=Submit border=0 name=Submit22>
</FORM></code>
I process these values in register.php, well i want to return either , registration ok or invalid to this page so i could insert a php script in this such as,
<code>
<html>
<body>
<?php
$theresult = $_GET['result'];
if($result =="invalidpass"){
echo "Invalid Password";
}elseif($result =="invaliduser"){
echo "Invalid username";
}
?>
<FORM action=register.php method=post>
<INPUT class=table_text
name=username>
<INPUT class=table_text
type=password name=password>
<INPUT type=image height=20
width=94
src="btn_register_green.gif"
align=top value=Submit border=0 name=Submit22>
</FORM></code>
and in my register.php i would have,
<code>if(!empty($result)){
$link = mysql_query("select password from tlogin where password = '".$password."' LIMIT 1");
$result = mysql_fetch_row($link);
if(empty($result)){
Header("Location: login.php?result=invalidpass");
}else{
Header("Location: main.php");
}
}else{
Header("Location: login.php?result=invaliduser");
}</code>
this all works fine apart from when you load the page in the first place, as there is no query string just register.php so hence i get an error echoed where the invaild password or invalid username would be saying unknow index result.
How would i get around this, i just need to avoid this error being displayed on the page?
