passing variables from forms not working

[slagbanger]

I have windows XP Pro, IIS 5 and PHP4 installed. It all works nicely (phpinfo() does anyway)

When i try and pass variables form a form, they do not work. Any example from the net seems to not work and my php page does not recognise that variables have been passed. I shall give you an example below. When i click submit on the form, the ?username=username&password=password getzs added on to the url, as it should but the pho dont pick it up.

This page is called mypage.php. Taken from an example that dont work:

<?php
if (isset($submit) && $submit=="yes")
{
echo "Thank you for submitting the form"
} else {
?>
<form action="mypage.php" action=post>
<input type=text name=username>
<input type=text name=password>
<input type=submit name=submit value=add>
</form>
<?php
}
?>

This form re appears and does not say thank you, just the url at the address bar is updated as mentioned above and the form re appears with the form like it never got submitted.

Please help. I am new to php. I am amazed at the ease so far but cannot get around this problem!!! But i can use mysql happily!!

in ure if-condition u're checking if $submit=="yes" , but u've given the value of submit as "add" in the form

change it to submit=="add"

That has not worked. I do agree that there is a problem there, but i changed the value of submit to yes, and it has not helped. It still does the same thing.

BTW, i have a standard install, using the installed php.ini, not the php.ini-recommended or whatever its called (remember from my linux days) I have changed the way it reports errors so it dont do my head in. That is all. Is there a setting in there or in IIS? I have also installed lockdown for IIS, the microsoft security thing. Would this affect the situation??

Do you have globals set to on (note globals are set to off by default).

I'd change

if (isset($submit) && $submit=="yes")

to

if (isset($_POST['submit']))

[slagbanger]

I thought that globals=on was a potential security risk. Or is it ok, but i have to write code better?? I did what is mentioned above and it has not helped

I think that the submit doesn't have a real value. its type is "submit" which triggers the form action. the value only sets what the button says.

you should be checking the existance of the two variables you are sending

username and password

something like

if ((!$POST['strCountyName']) || (!$POST['strCountyName'])){

and setting a cookie for the next time

good luck

This does work. called from login.htm that passes the values:

<?php
        session_start();
        $db_user = 'root';
        $db_pass = 'i aint that silly!;
        $user_name = $_POST['user_name'];
        $password = $_POST['password'];

    //connect to the DB and select the "dictator" database
    $connection = mysql_connect('localhost', $db_user, $db_pass) or die(mysql_error());
    mysql_select_db('dictators', $connection) or die(mysql_error());

    //set up the query
    $query = "SELECT * FROM users
                    WHERE user_name='$user_name' AND password='$password'";

    //run the query and get the number of affected rows
    $result = mysql_query($query, $connection) or die('error making query');
    $affected_rows = mysql_num_rows($result);

    //if there's exactly one result, the user is validated. Otherwise, he's invalid
    if($affected_rows == 1) {
            print 'validated';
    }
    else {
            print 'not valid';
            print $user_name;
    }
    print '<br>User name is' .$user_name;
    print '<br>POassword is ' .$password;

    ?>
