DigitalMind Posted September 27, 2010 Share Posted September 27, 2010 I don't know what you want but use session_start() before any output Quote Link to comment Share on other sites More sharing options...
phpnewbei Posted September 27, 2010 Author Share Posted September 27, 2010 What do you mean? I have a session_start(); right after the php tags. Quote Link to comment Share on other sites More sharing options...
DigitalMind Posted September 27, 2010 Share Posted September 27, 2010 You have a lot of html code (that's also output) before the php tag. in your case it should be: <?php session_start(); ?> html blah-blah-blah.... <?php additional php code ?> Quote Link to comment Share on other sites More sharing options...
phpnewbei Posted September 27, 2010 Author Share Posted September 27, 2010 I've done that now, but it still don't work cuz in my address field When I'm logged in as "Machram" and click in my profile the address field is : http://localhost/project/members.php?uname=Machram When I go to like "http://localhost/project/members.php?uname=Test" It still says the same thing on the page "Echo "Hello";" Quote Link to comment Share on other sites More sharing options...
DigitalMind Posted September 27, 2010 Share Posted September 27, 2010 ($_SESSION["username"] == isset($_GET["uname"])) that's wrong. isset returns just TRUE or FALSE. remove isset() from this part of your code. Quote Link to comment Share on other sites More sharing options...
phpnewbei Posted September 27, 2010 Author Share Posted September 27, 2010 Ahh, thankyou It works properly now. I'll try to work on my own now, if it's something i'll write it here. Again, thankyou! Quote Link to comment Share on other sites More sharing options...
DigitalMind Posted September 27, 2010 Share Posted September 27, 2010 you're welcome! use isset() in a separate if () at the beginning like $uname = isset($_GET['uname']) ? $_GET['uname'] : 'guest'; (after that use $uname instead of $_GET['uname']) Quote Link to comment Share on other sites More sharing options...
phpnewbei Posted September 27, 2010 Author Share Posted September 27, 2010 Could you explain more how the code works and what it means? Quote Link to comment Share on other sites More sharing options...
DigitalMind Posted September 27, 2010 Share Posted September 27, 2010 $uname = isset($_GET['uname']) ? $_GET['uname'] : 'guest'; means if (isset($_GET['uname'])) { // if uname variable is supplied by the GET request $uname = $_GET['uname']; } else { $uname = 'guest'; // if uname was not supplied we set it to 'guest' } after that you should use ... $_SESSION['username'] == $uname (instead of $_GET['uname']) Quote Link to comment Share on other sites More sharing options...
phpnewbei Posted September 27, 2010 Author Share Posted September 27, 2010 So I should place $uname = isset($_GET['uname']) ? $_GET['uname'] : 'guest'; in the beginning? Quote Link to comment Share on other sites More sharing options...
phpnewbei Posted September 27, 2010 Author Share Posted September 27, 2010 Now I have an UPDATE error heh, here's my code: elseif ($_SESSION["username"] == (isset($_GET["changeinfo"]))) {$sql = mysql_query("SELECT * FROM userinfo WHERE username='" . $_SESSION["username"] . "'");while($row = mysql_fetch_array($sql)){echo "<form method=\"POST\" action=\"members.php?uname&changeinfo=" . $_SESSION["username"] . "\">";echo "<input type=\"text\" name=\"name\" value=\"" . $row["firstname"] .

"");}} Quote Link to comment Share on other sites More sharing options...
DigitalMind Posted September 27, 2010 Share Posted September 27, 2010 So I should place $uname = isset($_GET['uname']) ? $_GET['uname'] : 'guest'; in the beginning? yes but after session_start(); Quote Link to comment Share on other sites More sharing options...

phpnewbei Posted September 27, 2010 Author Share Posted September 27, 2010 What's the differences between " and ' ? By the way, it doesn't update the table ;/ Quote Link to comment Share on other sites More sharing options...
phpnewbei Posted September 27, 2010 Author Share Posted September 27, 2010 Now, If I write something in my input fields and update, it works, but when I go back and change the information again, the field in my database gets emtpy :S My guess would be that when the database have been update, nothing happends, you'll return to the input field again.

DigitalMind Posted September 27, 2010 Share Posted September 27, 2010 Of course if(isset($_SESSION["username"])){ is false. You've missed out session_start();! Quote Link to comment Share on other sites More sharing options...
