I have a register form where a user enters a full name, email and password. I do not want to give them the option of choosing their own "username"; rather I want to automatically create the username from their "full name". So far I can create the username by removing space and symbols from full name. Like this. $fullname = trim($_GET['fullname']); $username = preg_replace('/\s+/', '', $fullname); Looking at that, John Smith would become "johnsmith". Since there could be dozens of people with the name "john smith", I was thinking of assigning unique number to each of them. Like this "johnsmith1", "johnsmith2", "johnsmith3"..etc. How would you say I go on incrementing the username like that? -
I am new to PHP and MySQL, but not to coding in general. I finally got brave and I am trying to move from a MS Access database to a server based MySQL database with a web enabled front end. The goal of the database is to be online aviation logbook with the ability to enter/retrieve data with my iPhone. My ultimate end state is to code my app for the phone. I have exported all of my Access data to a MySQL database on server. I've spent the last two weeks learning PHP and MySQL by writing small scripts and expanding as I learned. I finally reached a point where I was ready to write the code for entering all of the data for a flight and inserting into the database. I had mastered all of the sub-steps. I built a form for entering the data. The form querys the DB to populate some of the drop down menus. All of that works fine and the drop menus are populated with information from the DB. After I click on the "submit" button, the code throws an error. I eventually learned how to capture and display the error. I was getting the following: Access denied for user ''@'localhost' to database 'FltLogbook'. Initially, I thought that maybe there was some sort of data type mismatch (I wasn't displaying the error initially, just a phrase stating the add failed) and I ended up commenting out the INSERT query and trying to insert just one piece (column) of data. That didn't work. Then I finally stumbled on the method to display the error. After seeing the actual error statement, I thought that I was losing DB connectivity after pressing submit and executing the code or it may be a permission issue. If I place the "INSERT" code up in the portion of the code where the form is built, I can successfully add a record. So my username/password has the correct privileges since I can add a record using the code - just not where I want to do it. After googling, it looks like the code is passing a null value for user (and I assume password). I have no idea why, but suspect it has something to do with the "POST" process after the submit. Stumbling upon another function (connection_status), it passes a "0" for normal in both sections of the code. I am truly stumped and have been this way for three days now!! I have googled anonymous, the exact error phrase, etc. None of it has helped me bridge this impasse. I am sure, as in previous coding impasses, it will be quite obvious to someone.

Hey guys, No this may very well be a silly question and if it is, I'm certain to have a decent bit of embarrassment, as I'm somewhat of a veteran when it comes to PHP but I've only just started to look for a viable solution to this particular hiccup. Is there a way in the PHP Header file to include "print $_SESSION ['username']", without it causing a syntax error? I'll provide more context by embedding my code! <?php if ((isset($_SESSION['user_id']))&&(!strpos($_SERVER['PHP_SELF'],'logout.php'))) { print '<span> <a href="login/" id="link-login">Log in</a> <span class="pre-login-or">or</span> <a href="register/" id="link-register">Register</a></span>'; } else{ print 'Benvenutti $_SESSION ['username'], al Torneo di Briscola due mila tredici'; }?> That in itself will cause an unexpected T_STRING syntax error... the only option I can see is by employing the use of an iframe and linking the source to a separate PHP document with the "Welcome" text, but I was hoping there was another was to achieve this with the iframe.
