SQL not returning value even though it's there...

[Anthony Papillion II]

Hello Everyone,

I have been having fits with a simple PHP script and I'm hoping it's
something that someone here can help me with. Basically, when I execute the
SQL statement directly on the MySQL CLI, it returns. But when I run the same
statement through the following PHP script, I *think* it returns an empty
set.

I say I think because the if(mysql_num_ro ws($recset) > 0){} block is
executed. But when I try to retreive values stored in my array, I get
blanks. Can someone offer me some help? Thanks in advance -- Anthony

=== SCRIPT ===
<?php
include("db.php ");

$incoming_user = stripslashes($_ POST['username']);

$sql = "SELECT * FROM tblSisters WHERE username != '$incoming_user ' AND
isTaken != 'yes' ORDER BY RAND() LIMIT 1";

$recset = mysql_query($sq l, $conn);

if(mysql_num_ro ws($recset) > 0){
$row = mysql_fetch_row ($recset);
echo "<table border=\"1\" align=\"center\ " cellspacing=\"7 \">\n";
echo "<tr>\n";
echo "<th>USERNA ME</th>\n";
echo "<th>WANTS MAIL</th>\n";
echo "</tr>\n";
echo "<tr>\n";
echo "<td>$row[username]</td><td>$row[wsm]</td>\n";
echo "</tr>\n";
echo "</table>\n";

// Update the database to reflect the new selection

$sql2 = "UPDATE tblSisters SET isTaken='yes', takeBy='$incomi ng_user' WHERE
username='row[username]'";
mysql_query($sq l2, $conn);
}
else{
echo "<h2><u><b>RECO RD RETREIVAL FAILURE</b></u></h2><br>\n";
echo "The secret sister database could not be queried. Please try again ";
echo "later or contact the system administrator.\ n";
}
?>

If you were running with error_reporting set to E_ALL, you would see an
"undefined array index" notice here which would have helped you diagnose
the problem: mysql_fetch_row returns an enumerated array, not an
associative array.

If you want to access columns by name, use mysql_fetch_arr ay (or
mysql_fetch_obj ect to use object syntax).

See the online manual for additional information:
http://www.php.net/error_reporting
http://www.php.net/mysql_fetch_row

Use mysql_fetch_ass oc() instead of mysql_fetch_row (). The first returns
an associative array, the latter a numeric one.

Hi

mysql_fetch_row () creates an integer indexed array. You are using
associated indexes to output the row data. The index does not exist.
To use associative indexes simply change mysql_fetch_row () to
mysql_fetch_arr ay() or mysql_fetch_ass oc()

e.g => $row = mysql_fetch_arr ay($recset);

Peter

If you were running with error_reporting set to E_ALL

or even better E_ALL | E_STRICT under PHP 5 in developement servers.

LOL I can't believe it was something THAT simple and THAT obvious. I *knew*
that mysql_fetch_arr ay() was the function to use (I've been using it
forever) but I totally spaced it out on this one. I didn't even know that
there was a mysql_fetch_row () function. Geez, now I feel stupid. Thanks for
your input.
