Php - Comment Section - How Display Username
Spencer posted a topic in Website Management and Coding
Hey there! Recently, I have made a comment section on my website. It worked great, but to show who posted a comment, a user would have to type in who they are in the "Comment By:" inputbox. I don't want this anymore, due to users being able to impersonate one another. I want to make it show actually who posted it. ( Yes. I have a working register and login ). Here is my news:chatroom_first_priority.php code ( Note: I have removed the Comment By: inputbox and all the rest of that stuff. This is my attempted code. If needed, tell me you want to see my original code. ) : <?php session_start(); if(!session_is_registered(myusername)){ header("location:/login/main_login.php"); } $myusername = $_SESSION['myusername']; ?> <html> <head> <title>Mbox:News</title> <script> </script> <style> /*3DS SCREEN START*/ div#topscreen { position: absolute; top: 0px; left: 0px; height: 1300px; width: 320px; background-color:#1E90FF; z-index:2; } div#bottomscreen { position: absolute; top: 218px; left: 0px; height: 212px; width: 320px; background-color:#1E90FF; } /*3DS SCREEN STOP*/ /* WELCOME USERNAME STYLE START */ div#welcome_username { text-decoration:none; color:#000000; font-weight: bold; background-color:aqua; text-align:center; } /* WELCOME USERNAME STYLE STOP */ a.logout { text-decoration:underline; color:#000000; font-weight:bold; background-color:#FFFFFF; position:absolute; top:0px; left:250px; } a.home { text-decoration:underline; color:#000000; font-weight:bold; background-color:#FFFFFF; position:absolute; top:0px; left:5px; } a:link { color:#000000; text-decoration:underline; } a:visited { color:#000000; text-decoration:underline; } a:hover { color:#FF0000; text-decoration:none; } p.article_by { background-color:lime; text-align:left; font-weight:bold; } </style> <meta name="viewport" content="width=320"> </head> <body> <!-- TOP SCREEN --> <div id="topscreen"> <?php //echo "Welcome, " . $myusername .

So now, it will say all of the comments are posted by YOU. Thanks for the help! I appriciate it! ~ Spencer
