Namtip Posted September 19, 2010 Share Posted September 19, 2010 I'm trying to create a profile page that an unregistered user can view when he enters in the username into the url (e.g. http://localhost/username) Just recently got my mode_rewrite going (tried and tested), but I don't get the users information coming up in the page. Am I going about this the right way? This is what the page shows: The requested page was: Notice: Undefined variable: name_id in C:\x\xampp\htdocs\pages\profile.php on line 27 Notice: Undefined variable: name in C:\x\xampp\htdocs\pages\profile.php on line 28 Notice: Undefined variable: password in C:\x\xampp\htdocs\pages\profile.php on line 29 profile.php <?php include 'db.inc.php'; $db = mysql_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASSWORD) or die ('Unable to connect. Check your connection parameters.'); mysql_select_db(MYSQL_DB, $db) or die(mysql_error($db)); $query = 'SELECT name_id, name, password FROM user WHERE name = "' . mysql_real_escape_string($_GET['name'], $db) . '"'; $result = mysql_query($query, $db) or die(mysql_error()); ?> <html> <head> <title> <?php echo $name; ?> </title> </head> <body> <p> The requested page was: <?php echo $name_id; echo $name; echo $password; ?> </p> </body> </html> I've been messing around with this for awhile so I'm going to hit the sack.

sKunKbad Posted September 19, 2010 Share Posted September 19, 2010 What do your rewrite rules look like? Link to comment https://forums.phpfreaks.com/topic/213786-viewing-profile-information-through-the-url/#findComment-1112701 Share on other sites More sharing options...
PFMaBiSmAd Posted September 19, 2010 Share Posted September 19, 2010 You are executing the query, but not fetching anything from the result set, so it will be a little hard to display anything.

Namtip Posted September 19, 2010 Author Share Posted September 19, 2010 My rewrite values look like that. Options +FollowSymlinks RewriteEngine on RewriteOptions MaxRedirects=10 RewriteRule ^(.{4,12})$ http://localhost/pages/profile.php?name=$name [NC] RewriteRule ^$http://localhost/pages/login.php [R=301,NC] Do I need to change the WHERE part of the query? Because the mysql matches up with the script I run below to configure mysql. $query = 'CREATE TABLE IF NOT EXISTS user ( name_id INTEGER UNSIGNED NOT NULL AUTO_INCREMENT, name VARCHAR(50) NOT NULL, password CHAR(41) NOT NULL, admin_level TINYINT UNSIGNED NOT NULL DEFAULT 0, PRIMARY KEY (name_id) ) ENGINE=MyISAM'; mysql_query($query, $db) or die (mysql_error($db)); Link to comment https://forums.phpfreaks.com/topic/213786-viewing-profile-information-through-the-url/#findComment-1112793 Share on other sites More sharing options...

WHERE name = "' . mysql_real_escape_string($_GET['name'], $db) . '"'; Is this the right way of pulling the url variable to cross reference and select the database? Does the 'name' variable need to be a primary key for it to pull the related information into the page? Is it correct for me to be using the $_GET function?

Namtip Posted September 19, 2010 Author Share Posted September 19, 2010 I've echoed the variable: echo $_GET['name']; but it only displays "$name" instead of the value I've typed in the url. This is why the query isn't being executed in the way I like. How do I get the value to be what I asked it to be in the url??

PFMaBiSmAd Posted September 19, 2010 Share Posted September 19, 2010 In a way, that is kind of funny. "$name" is exactly what your rewrite rule is setting ?name= equal to. I think you meant to use $1 Link to comment https://forums.phpfreaks.com/topic/213786-viewing-profile-information-through-the-url/#findComment-1112976 Share on other sites More sharing options...
samoi Posted September 19, 2010 Share Posted September 19, 2010 I'm not positive of what you want exactly. But I will try to help! You need to fetch the row that mysql_query returned to echo out the vars $name, $name_id, $password! something like this will be good! <?php include 'db.inc.php'; $db = mysql_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASSWORD) or die ('Unable to connect. Check your connection parameters.'); mysql_select_db(MYSQL_DB, $db) or die(mysql_error($db)); $query = 'SELECT name_id, name, password FROM user WHERE name = "' . mysql_real_escape_string($_GET['name'], $db) . '"'; $result = mysql_query($query, $db) or die(mysql_error()); // something like this will do the trick! $name_id = $result[0]; $name = $result[1]; $password = $result[2]; ?> That's it!

PFMaBiSmAd Posted September 19, 2010 Share Posted September 19, 2010 $result isn't the data values that the query returns. Link to comment https://forums.phpfreaks.com/topic/213786-viewing-profile-information-through-the-url/#findComment-1112990 Share on other sites More sharing options...
