Question

I create a table using PHP from a database, meaning the size of the table and values vary.

The table creation:

<table>     
            <thead>
                <tr>
                    <th>Ticket</th>
                    <th>Empresa</th>
                    <th>Requerente</th>
                    <th>Motivo</th>
                    <th>Data</th>
                    <th>Hora</th>
                </tr>
            </thead>

        <tbody>
            <form name="goTicket" action="resolver.php" method="POST" >         
<?php   
    $sql = "QUERY";
    $result = mysql_query($sql);
    while ($row = mysql_fetch_array($result)) {
        echo "<tr onmouseover=\"this.style.background='#EFF5FB';this.style.cursor='pointer'\"
        onmouseout=\"this.style.background='white';\" onclick=\"javascript: submitform()\">";
        echo "<td>$row[Ticket]</td>";
        echo "<input type='hidden' name='_ticket' value='$row[Ticket]' />";
        echo "<td>$row[Empresa]</td>";
        echo "<td>$row[Requerente]</td>";
        echo "<td>$row[Motivo]</td>";
        echo "<td>$row[Data]</td>";
        echo "<td>$row[Hora]</td>";
        echo "</tr>";
    }
    echo "</form>";
    echo "<tr><td colspan='6' style='text-align: center;'><form action='adminmenu.php' ><br /><input type='submit' name='woot' value='Main Menu' /></form></td></tr>";  
    echo "<tbody>";
    echo "</table>";
?>

The Javacript function used to submit is this one:

<script type="text/javascript">
        function submitform()
        {
            document.forms["goTicket"].submit();          
        }
</script>

Now whenever I click on a row it takes to the appropriate page “resolver.php” but always sends the most recent data, from last time the while was executed.

I need the value from the first cell, or the hidden input tag, that contains what I need, from the row I click.

Thank you.

Full suggestion

 <script type="text/javascript">
 function submitform(ticket) {
   document.goTicket.elements["_ticket"].value=ticket;
   document.goTicket.submit();
 }
 </script>
 <table>     
        <thead>
            <tr>
                <th>Ticket</th>
                <th>Empresa</th>
                <th>Requerente</th>
                <th>Motivo</th>
                <th>Data</th>
                <th>Hora</th>
            </tr>
        </thead>

    <tbody>
<form name="goTicket" action="resolver.php" method="POST" >
<input type="hidden" name="_ticket" value="" />

<?php   
    $sql = "QUERY";
    $result = mysql_query($sql);
    while ($row = mysql_fetch_array($result)) {
?>    

    <tr onmouseover="this.style.background='#EFF5FB';this.style.cursor='pointer'"
    onmouseout="this.style.background='white';" 
    onclick="submitform('<?php echo $row[Ticket]; ?>')">
    <td><?php echo $row[Ticket];     ?></td>
    <td><?php echo $row[Empresa];    ?></td>
    <td><?php echo $row[Requerente]; ?></td>
    <td><?php echo $row[Motivo];     ?></td>
    <td><?php echo $row[Data];       ?></td>
    <td><?php echo $row[Hora];       ?></td>
    </tr>
<?php } ?>

</form><!-- not really nice -->
   <tr><td colspan="6" style="text-align: center;"><form action="adminmenu.php" >
   <br /><input type="submit" name="woot" value="Main Menu" /></form></td></tr>
    </tbody>
   </table>
