Question

I am trying to write a simple stream, streaming everything from a mysql field. But my current script shows absolutely nothing.. no errors, nothing. Here it is:

include("user_sytem_scripts/connect.php");

   $sql_updates = mysql_query("SELECT item_id, username, item_content, update_time FROM updates ORDER BY update_time DESC LIMIT 30")  or die("Query failed with error: ".mysql_error());

while($row = mysql_fetch_array($sql_updates)){

    $update_id = $row["item_id"];
    $update_username = $row["username"];
    $item_content = $row["item_content"];
    $update_time = $row["update_time"];

$updatestream = '
   <table style="background-color:#FFF; border:#999 1px solid; border-top:none;" cellpadding="5" width="100%">
                    <tr>
                    <td width="90%" valign="top" style="line-height:1.5em;">
                    <span class="liteGreyColor textsize9">' . $update_time . ' <a href="profile.php?id=' . $update_username . '"><strong>' . $username . '</strong></a> via <em></em></span><br />
                     ' . $item_content . '
            </td>
            </tr></table>'; }

Then down in the HTML I use: <?php echo $updatestream ?>


But as i said i get absolutly nothing.. Can anyone spot any errors or general mistakes that would cause this? Thanks 😀

Answer 1

I would check the following:

1. Does the query run when you run it manually (in phpMyAdmin for example)?
2. Do you get any output at all? If not, it seems that your while look is getting 0 results from the DB.

You should also change: $updatestream = ' to $updatestream .= so that you append text, in the current while loop you’ll overwrite the last $updatestream value.
