i have set up a blog based on wordpress. I want to add user specific data which is read-only for the users. So i created two fields : user_survey and user_survey_complete in wp_users tables
Now I want the users to be able to view the data under these colums but only for their own accounts . I don't know how to use session function so I created a page which asks for the user_id and user_pass and returns the data under field user_survey and user_survey_complete
Instead of returning the data in user_survey and user_survey_complete , it just returns the heading user_survey and user_survey_complete

the code which asks for data is :
<form id="FormName" action="surveycheck.php" method="post" name="FormName">
<table width="448" border="0" cellspacing="2" cellpadding="0">

<td width="150" align="right"><label for="user_id">Username</label></td>
<td><input name="user_id" maxlength="32" type="text" value="<?php echo stripslashes($user_id) ?>"></td>

<td width="150" align="right"><label for="user_pass">Password</label></td>
<td><input name="user_pass" maxlength="32" type="text" value="<?php echo stripslashes($user_pass) ?>"></td>

<td colspan="2" align="center"><input name="" type="submit" ></td>


The code which I used to display the data
<html><head><title>MySQL Table Viewer</title></head><body>
$db_host = 'localhost';
$db_user = 'userid';
$db_pwd = 'password';

$database = 'wordpress_management';
$table = 'wp_users';

$user_id = trim(mysql_real_escape_string($_POST["user_id"]));
$user_pass = trim(mysql_real_escape_string($_POST["user_pass"]));
if (!mysql_connect($db_host, $db_user, $db_pwd))
die("Can't connect to database");

if (!mysql_select_db($database))
die("Can't select database");

// sending query
$result = mysql_query("SELECT user_survey_link, user_survey_compelete FROM {$table} WHERE {$user_id}=user_login AND {$user_pass}=user_pass ");
if (!$result) {
die("Query to show fields from table failed");

$fields_num = mysql_num_fields($result);

echo "<h1>Table: {$table}</h1>";
echo "<table border='1'><tr>";
// printing table headers
for($i=0; $i<$fields_num; $i++)
$field = mysql_fetch_field($result);
echo "<td>{$field->name}</td>";
echo "</tr>\n";
// printing table rows
while($row = mysql_fetch_row($result))
echo "<tr>";

// $row is array... foreach( .. ) puts every element
// of $row to $cell variable
foreach($row as $cell)
echo "<td>$cell</td>";

echo "</tr>\n";
Please help me in displaying the data under the fields.
If someone know wordpress then please help me use session instead of asking for userid and pass
I am a noob and not good at php so please provide the solution in detail
Thanks a lot
