Insert data into oracle database using a PHP form

Question

I'm trying to enter data into my oracle database table using a php form. When I click submit no data is added. Could someone help me please. I'm new to php/oracle thing.
NOTE: I don't have any problem connecting to the database using php.
Here is the code I'm using:
<?php
// just print form asking for name if none was entered
if( !isset($query)) {   
echo "<form action=\"$uri\" method=post>\n";
echo "<p>Enter Name: ";
echo "<input type=text size=100 maxlength=200 name=data value=\"$data\">\n";
echo "<br><input type=submit name=submit value=Submit>\n";
echo "</form>\n";
exit;
// insert client's name
$query = "INSERT INTO client (name) VALUES ($data)";
// connect to Oracle
$username = "xxxx";
$paswd = "yyyyyy";
$dbstring = "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)".
"(HOST=patriot.gmu.edu)(PORT=1521))".
"(CONNECT_DATA=(SID=COSC)))";
$db_conn = ocilogon($username, $paswd, $dbstring);
$stmt = OCIParse($db_conn, $query);
OCIExecute($stmt, OCI_DEFAULT);
OCIFreeStatement($stmt);
OCILogoff($db_conn);
?>
Thanks for your help. I will also appreciate a better was to do it.

resumption and jer,
Sorry I cannot format the code for easy reading!
The page is submitting to itself. See action = \"$uri\". I used the same logic to enter SELECT querries into the database. It pulls and displays data back on the webpage. The code I used for this is below. Compare it with the one above for inserting data into the table.
<?php
// connect to oracle
$username = "xxxxx";
     $paswd = "yyyyy";
     $dbstring = "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)".
          "(HOST=patriot.gmu.edu)(PORT=1521))".
          "(CONNECT_DATA=(SID=COSC)))";
     $db_conn = ocilogon($username, $paswd, $dbstring);
// username and password will be unset if they weren't passed,
// or if they were wrong
if( !isset($query)) {
// just print form asking for account details
echo "<form action=\"$uri\" method=post>\n";
echo "<p>Enter Query: ";
echo "<input type=text size=100 maxlength=200 name=query value=\"$query\">\n";
echo "<br><input type=submit name=submit value=Submit>\n";
echo "</form>\n";
exit;
// remove unwanted slashes from the query
$query = stripslashes($query);
// run the query
$stmt = OCIParse($db_conn, $query);
OCIExecute($stmt, OCI_DEFAULT);
// Open the HTML table.
print '<table border="1" cellspacing="0" cellpadding="3">';
// Read fetched headers.
print '<tr>';
for ($i = 1;$i <= ocinumcols($stmt);$i++)
print '<td class="e">'.ocicolumnname($stmt,$i).'</td>';
print '</tr>';
// Read fetched data.
while (ocifetch($stmt))
// Print open and close HTML row tags and columns data.
print '<tr>';
for ($i = 1;$i <= ocinumcols($stmt);$i++)
print '<td class="v">'.ociresult($stmt,$i).'</td>';
print '</tr>';
// Close the HTML table.
print '</table>';
OCIFreeStatement($stmt);
OCILogoff($db_conn);
?>
