    i really need to know if its right or if it is wrong…

  16. When I downloaded the demo from your actual site it didn't give me file with "demo-form.php" only a "demo.php" that is the form. It looks like you have six files open but I only have 5 that got downloaded. Help!!

    Also do you happen to have a tutorial on how to create those country, state, city selectors? That's really what I'm looking for but I'm hoping to make it myself with the knowledge you have provided.

    Let me know. 🙂

    Thanks,
    Naya

  18. Whenever I go to make the database I do the ID and input1. When I go to get the final product, I get "MySQL returned an empty result set (i.e. zero rows). (Query took 0.0000 sec)" and I don't know what to do.

  19. just a bullshit first of all i just came here to know how the informations stores into the database and you've described a lot about css and html (very disturbing) after that when i saw the main thing that i'm here for but its also not fully cleared you have done many things without showing how to

  20. Yes here is my script.
    <?php
    define ('DB_NAME','newebay');
    define ('DB_USER','root');
    define ('DB_PASSWORD','bh05238');
    define ('DB_HOST','localhost');

    $link = mysql_connect('DB_HOST','DB_USER','DB_PASSWORD');

    IF (!$link) {
     die('Could not Connect :
        ' . mysql_error());
     
    }

    $db_selected = mysql_select_db (DB_NAME, $link);

    if (!$db_selected) {
    die('Can't use ' . DB_NAME . ': ' . mysql_error());

    }
    echo 'Connected successfully';

    ?>

    Thanks for the Fast response!

  21. Hi John,  Love your videos so far.  Having a issue trying to get php to connect to mysql.  I keep getting this message. "php_network_getaddresses: getaddrinfo failed: Name or service not known".  I think the issue is the 'DB_HOST'.  I verified using mysql workbench that its name is local host.  I even tried putting the port number into the variable 'DB_HOST' = 'localhost:3306' and still didn't work.  What do you suggest?

  27. @Justin Emerson
    If you delete the function he wrote in there that is called $value=$_POST['input1'];
    and then where he has the next line of code stating $sql = "INSERT INTO demo (input1) VALUES ('$value'); and change it to $sql = "INSERT INTO Pledge (ID, Names) VALUES ('','$_POST[input1]')";
    then it should work. Just remember that you need to add security to something like this and if you don't it is very easy to retrieve the information in your box by simply putting a retrieve code.

  36. hi John, I have a question Where can I find the PHP codes where you are showing define ('DB_name', demo') on my form I indicated ID, Login and Password (3 columns) but I do not know where can I find these code that you are showing PHP
