Hello

I'm currently working on a "profile-script". It displays the information staying in the mysql database table 'users'.
One of my friends and I worked on it but we still don't get it. It always says that the mysql_fetch_array supplys an invalid argument.

here is the code:
<?php

$user = $_GET['user'];

$con = mysql_connect("localhost","name","password");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

mysql_select_db("my_db", $con);

$sql = "SELECT `username`,`geld`,`avatar`,`joined`,`posts`,`topics`,`shouts` FROM users WHERE `username`='" . $user . "'";
$result = mysql_query($sql,$con);

if(mysql_num_rows($result)==1){

while($row = mysql_fetch_array($result)){
echo "<table border=1>";
echo "<tr><td bgcolor=black><center> Username: </center></td>";
echo "<td bgcolor=black><center>" . $row['username'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Geld: </center></td>";
echo "<td bgcolor=black><center>" . $row['geld'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Avatar: </center></td>";
echo "<td bgcolor=black><center>" . $row['avatar'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Joined: </center></td>";
echo "<td bgcolor=black><center>" . $row['joined'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Posts: </center></td>";
echo "<td bgcolor=black><center>" . $row['posts'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Topics: </center></td>";
echo "<td bgcolor=black><center>" . $row['topics'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Shouts: </center></td>";
echo "<td bgcolor=black><center>" . $row['shouts'] . "</center></td>";
echo "</table>";
echo "<table border=1><tr height=30%><colgroup width=500></colgroup>";
echo "<td bgcolor=black <center>";
}
}
else{
if(mysql_num_rows($result)==0)
{echo "no user found in database"; }
else{
echo "more than one user found in database";
}
}

?>

We get the $_get['user'] from the "memberlist" however, the memberlist.php is right programmed, we are pretty sure.
Help please.

Please report errors in the Staredit.Network forum.

Try mysql_fetch_assoc() instead.

None.

It's not best to use the <center> tag in HTML, as it's deprecated. I don't know if that's all the code you are using but you also have an open td and center tag at the end. But try this out:

Code

<?php
$user = $_GET['user'];
$con = mysql_connect("localhost","name","password");

if (!$con){
die('Could not connect: ' . mysql_error());
}

mysql_select_db("my_db");
$result = mysql_query("SELECT `username`,`geld`,`avatar`,`joined`,`posts`,`topics`,`shouts` FROM users WHERE `username`='" . $user . "'");

if(mysql_num_rows($result) == 0){
echo "no user found in database";
}
else if(mysql_num_rows($result) == 1){
while($row = mysql_fetch_array($result)){
echo "<table border=1>";
echo "<tr><td bgcolor=black><center> Username: </center></td>";
echo "<td bgcolor=black><center>" . $row['username'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Geld: </center></td>";
echo "<td bgcolor=black><center>" . $row['geld'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Avatar: </center></td>";
echo "<td bgcolor=black><center>" . $row['avatar'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Joined: </center></td>";
echo "<td bgcolor=black><center>" . $row['joined'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Posts: </center></td>";
echo "<td bgcolor=black><center>" . $row['posts'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Topics: </center></td>";
echo "<td bgcolor=black><center>" . $row['topics'] . "</center></td>";

echo "<tr><td bgcolor=black><center> Shouts: </center></td>";
echo "<td bgcolor=black><center>" . $row['shouts'] . "</center></td>";
echo "</table>";
echo "<table border=1><tr height=30%><colgroup width=500></colgroup>";
echo "<td bgcolor=black> <center>";
}
}
else{
echo "more than one user found in database";
}
?>

None.

Hello

Both didn't worked.

Please report errors in the Staredit.Network forum.

Hmm...you are inputting your name,pass, and database correct?

Add this at the end of your mysql_query, but before the semicolon:

Code

or trigger_error("Error querying database. Please contact administrator.")

If you get that error, then there is a problem with your query, which you might want to change to this:

Code

mysql_query("SELECT * FROM users WHERE `username`='" . $user . "'")

None.

Yeah, I was going to suggest that in your last topic: put error catching on all your sql queries.

None.

haha for sure. in some ways it's even more exciting because you can play EUD maps on regular battle.net, don't need to convince someone to download your mod to play with you. what did you do?
