Hello, I've always liked coding and lately I've learned a little but more of it.
Now I also understand sql and db a little more.
My problem is that my register.php file seems to give me a notice.
Notice: Undefined index: op in C:\wamp\www\hacks4all.wapzan.com\registration\register.php on line 11
and
Notice: Undefined index: op in C:\wamp\www\hacks4all.wapzan.com\registration\register.php on line 55
the code is the following:
<?php
// dbConfig.php is a file that contains your
// database connection information. This
// tutorial assumes a connection is made from
// this existing file.
include ("dbConfig.php");
//Input vaildation and the dbase code
if ( $_GET["op"] == "reg" )
{
$bInputFlag = false;
foreach ( $_POST as $field )
{
if ($field == "")
{
$bInputFlag = false;
}
else
{
$bInputFlag = true;
}
}
// If we had problems with the input, exit with error
if ($bInputFlag == false)
{
die( "Problem with your registration info. "
."Please go back and try again.");
}
// Fields are clear, add user to database
// Setup query
$q = "INSERT INTO `dbUsers` (`username`,`password`,`email`) "
."VALUES ('".$_POST["username"]."', "
."PASSWORD('".$_POST["password"]."'), "
."'".$_POST["email"]."')";
// Run query
$r = mysql_query($q);
// Make sure query inserted user successfully
if ( !mysql_insert_id() )
{
die("Error: User not added to database.");
}
else
{
// Redirect to thank you page.
Header("Location: register.php?op=thanks");
}
} // end if
//The thank you page
elseif ( $_GET["op"] == "thanks" )
{
echo "<h2> Thanks for registering!</h2> ";
}
//The web form for input ability
else
{
echo "<form action=\"?op=reg\" method=\"POST\"> \n";
echo "Username: <input name=\"username\" MAXLENGTH=\"16\"> <br /> \n";
echo "Password: <input type=\"password\" name=\"password\" MAXLENGTH=\"16\"> <br /> \n";
echo "Email Address: <input name=\"email\" MAXLENGTH=\"25\"> <br /> \n";
echo "<input type=\"submit\"> \n";
echo "</form> \n";
}
// EOF
?>
For what I see it's something with the "op".
In the code at line 10 it says "Input vaildation and the dbase code" and I don't know what it exactly means. If you could please help me, I would really appreciate it!
Thank you, Emanuel.
