    Problem with a code.

    I have this code for a registration form, but when I run the code I get this error on the top of the page.

    Error Message:
    Notice: Undefined index: doRegister in /home/paradise/public_html/members/register.php on line 21

    This is the code:

    The form which submits to this page must contain at least the equivalent of:

    PHP Code:
    <form methodPOST>
    <
    intput name="doRegister" value="Register">
    <
    input type=submit>
    </
    form
    Which clearly it does not at the moment, hence your problem.

    @cups

    The op has

    Code HTML4Strict:
    <form action="register.php" method="post" name="regForm" id="regForm" >
    in their code.

    @OP

    Your problem appears to be in this line

    Code PHP:
    if($_POST['doRegister'] == 'Register')

    When you load the page the first time, you are trying to access $_POST['doRegister'] before it has been created because nothing has been submitted yet at this stage. Hence the "Undefined index" error because the index 'doRegister' in the array $_POST['doRegister'] doesn't exist because the array itself does not exist yet.

    In your IF statement you need to also check if the variable exists along with whether it is equal to a certain value.
