    This was also one of the problem. extra comma at the end of the "phone=?" bad: if ($stmt = $mysqli->prepare("UPDATE client_list SET company_name=?, contact=?, phone=?, WHERE id=?")) good: if ($stmt = $mysqli->prepare("UPDATE client_list SET company_name=?, contact=?, phone=? WHERE id=?")) - Herbert

    Hi Ben, it is actually if($name =='' || $last == '' || $phone == ''). I wonder if it's OK to use OR 3x? I don't want to post the whole codes I'm tying to solve it my self. Thanks! Herbert at GC.

    Hi Guys Help! This topic is from Complete Web Programmer tutorial (FYI the tutorial is great!). I'm trying to add a new row to the view.php page, I inserted a new row in PHPMyAdmin. I tweaked the codes (record.php), but it won't add the new record. The code currently use if statement to check for rows like this "if($name =='' || $last =='')", my code "if($name =='' || $last =='' || $mycode)" could the be the problem? I used OR 3x within if statement.??? Thank you, -- Herbert at GC

    The contact form is entirely built using HTML, and use PHP as processor. I think I will have to re-build the contact form using PHP to self submit, but I don't really now much about PHP yet. Thanks, Herbert

    Hi Ben, Thanks for your input. I'm using Dreamweaver to validate the form. I kind of think that someone has been viewing my contact page source code, cut and paste the full path to the browser, hit enter (key board) and goes the blank email. The reason I said this is because I was able to re-create it. So I was thinking that if I can hide the action attributes or the value then it will not be visible in the source code.??? Thanks, Herbert

    Hello everyone! I am new to this forum. I am really glad to be here. Help:( I've been receiving blank email from our website's contact us mail form. Is there a way to hide the action attribute so that it looks like this "action=" " ". Your help will be greatly appreciated - Herbert
