    Question displaying or updating a record from a list

    Hi! I'm pretty new to PHP and MySQL. I have a simple contact database, which I'm able to query using the following to produce a list of selected records:

    <?
    $user="username";
    $password="password";
    $database="your_database";
    $searchfirst=$_POST['first'];
    $searchlast=$_POST['last'];
    mysql_connect(localhost,$user,$password);
    @mysql_select_db($database) or die( "Unable to select database");
    $query="SELECT * FROM contacts WHERE (last='$searchlast') or (first='$searchfirst') ORDER BY last ASC";
    $result=mysql_query($query);
    $num=mysql_numrows($result);
    mysql_close();
    echo "<h1>Amir's Contacts Database</h1>";
    echo "<h2>Search Results</h2>";
    if ($num==0) {
    echo '<b>Sorry! There are no records which match your criteria.</b><br><br>';
    } else {
    echo '
    <table border=0 class="display" summary="line-up table">
    <tr class="heading">
    <th>View</th>
    <th>Name</th>
    <th>Phone</th>
    <th>Mobile</th>
    <th>Fax</th>
    <th>E-mail</th>
    <th>Website</th>
    </tr>';
    $i=0;
    while ($i < $num) {
    $id=mysql_result($result,$i,"id");
    $first=mysql_result($result,$i,"first");
    $last=mysql_result($result,$i,"last");
    $phone=mysql_result($result,$i,"phone");
    $mobile=mysql_result($result,$i,"mobile");
    $fax=mysql_result($result,$i,"fax");
    $email=mysql_result($result,$i,"email");
    $web=mysql_result($result,$i,"web");
    ?>
    <tr>
    <td><a href="pageview.php?id=$id"><? echo $id; ?></a></td>
    <td><? echo $first.' '.$last; ?></td>
    <td><? echo $phone; ?></td>
    <td><? echo $mobile; ?></td>
    <td><? echo $fax; ?></td>
    <td><a href="mailto:<? echo $email; ?>"><? echo $email; ?></a></td>
    <td><a href="<? echo $web; ?>" target="_blank"><? echo $web; ?></a></td>
    </tr>
    <?
    $i++;
    }
    }
    echo "</table>";
    ?>

    but when I try to click on the id field in the list, to update the record, the code I got from the tutorial I was doing doesn't work:

    <?
    $id=$_GET['id'];
    $user="username";
    $password="password";
    $database="your_database";
    mysql_connect(localhost,$user,$password);
    $query=" SELECT * FROM contacts WHERE id='$id'";
    $result=mysql_query($query);
    $num=mysql_numrows($result);
    mysql_close();
    $i=0;
    while ($i < $num) {
    $first=mysql_result($result,$i,"first");
    $last=mysql_result($result,$i,"last");
    $phone=mysql_result($result,$i,"phone");
    $mobile=mysql_result($result,$i,"mobile");
    $fax=mysql_result($result,$i,"fax");
    $email=mysql_result($result,$i,"email");
    $web=mysql_result($result,$i,"web");
    <form action="updated.php" method="post">
    <input type="hidden" name="ud_id" value="<? echo $id; ?>">
    First Name: <input type="text" name="ud_first" value="<? echo $first; ?>"><br>
    Last Name: <input type="text" name="ud_last" value="<? echo $last; ?>"><br>
    Phone Number: <input type="text" name="ud_phone" value="<? echo $phone; ?>"><br>
    Mobile Number: <input type="text" name="ud_mobile" value="<? echo $mobile; ?>"><br>
    Fax Number: <input type="text" name="ud_fax" value="<? echo $fax; ?>"><br>
    E-mail Address: <input type="text" name="ud_email" value="<? echo $email; ?>"><br>
    Web Address: <input type="text" name="ud_web" value="<? echo $web; ?>"><br>
    <input type="Submit" value="Update">
    </form>
    ++$i;
    }
    ?>

    What happens is I get the following error:

    "Parse error: parse error, unexpected '<' in /home/lunacy/public_html/fwmh/pageview.php on line 18"

    As I'm only selecting one record (id is primary key), I don't understand what the loop's for.

    All advice gratefully received.

    You need to place ?> and <?php around this:
    HTML Code:
    <form action="updated.php" method="post">
    <input type="hidden" name="ud_id" value="<? echo $id; ?>">
    First Name: <input type="text" name="ud_first" value="<? echo $first; ?>"><br>
    Last Name: <input type="text" name="ud_last" value="<? echo $last; ?>"><br>
    Phone Number: <input type="text" name="ud_phone" value="<? echo $phone; ?>"><br>
    Mobile Number: <input type="text" name="ud_mobile" value="<? echo $mobile; ?>"><br>
    Fax Number: <input type="text" name="ud_fax" value="<? echo $fax; ?>"><br>
    E-mail Address: <input type="text" name="ud_email" value="<? echo $email; ?>"><br>
    Web Address: <input type="text" name="ud_web" value="<? echo $web; ?>"><br>
    <input type="Submit" value="Update">
    </form>
