I am trying to fillup two select boxes using the result of a mysql

  • 0

I am trying to fillup two select boxes using the result of a mysql select query. I run the query once and use the output variable to loop and set options of select tag accordingly. The problem is, first select box gets populated as expected but the second one does not. It remains empty whatsoever. Heres my code

    <?php

    $con = mysql_connect('localhost','root','') or die('Could Not Connect'.mysql_error());
    mysql_select_db('irctc', $con)or die('Could Not Select'.mysql_error());;
    $result = mysql_query("select * from stationcodes", $con)or die('Could not select'.mysql_error());
    ?>
    <html>
    <head>
    </head>
    <body>
        <table>
            <tr>
                <td>Source</td>
                <td>:-</td>
                <td><select id='src'>
                    <option value=''>Select Source Station</option>
                    <?php  while($row = mysql_fetch_array($result))
                    { ?>
                        <option value='<?php echo $row['StationCode']; ?>'><?php echo $row['StationName']; ?></option>
                    <?php } ?>
                    </select>
                </td>
            </tr>
            <tr>
                <td>Destination</td>
                <td>:-</td>
                <td><select id='dst'>
                    <option value=''>Select Destination Station</option>
                    <?php  while($row = mysql_fetch_array($result))
                    { ?>
                        <option value='<?php echo $row['StationCode']; ?>'><?php echo $row['StationName']; ?></option>
                    <?php } ?>
                    </select>
                </td>
            </tr>
        </table>
    </body>
    </html>

    You need to “rewind” data pointer back to the beginning before starting to iterate over the results again. Use mysql_data_seek(0); to do that, before building your “Destination”:

                <td><select id='dst'>
                <option value=''>Select Destination Station</option>
                <?php  mysql_data_seek(0);         // reset data pointer to 1st row
                       while($row = mysql_fetch_array($result))
                { ?>
                    <option value='<?php echo $row['StationCode']; ?>'><?php echo $row['StationName']; ?></option>
                <?php } ?>
                </select>
            </td>

    Also do not use mysql_. Switch to mysqli_ or PDO. and it would help you to separate code from view and use any type of template engine (like Smarty)
