To accomplish this i set the username as a session variable (mostly because i had it display on all pages at the top right so the user could verify it was them as well as change any settings for their account). I am not sure if this is what you would want to do, but seeing as you already have a session going it seems like the easiest approach. I had a box when the user signs in for their username and literally just posted it to session username. $_SESSION['username']=$_POST['username']; As far as your line, echo "Welcome 'username'" is concerned, You arent actually telling it to echo the username you would have for that person, but rather just username itself.

Hey guys, I am fairly new to php and have been working on a project for about a week. I am currently running all of my queries and all of my events inside of my site. When i submit a form it checks for isset on that button then i run a function to process data. As far as readability, its getting pretty long and finding things when i need to change them is taking some time. I was looking into ajax for php form submit so i can do it without refreshing (with php self i dont have to refresh and i like it this way). As far as performance goes....which is better; the ajax form process or php self form process?
