Question

The following query works, but for some reason the first select statement is the only URL being displayed. Items from other tables are displayed, however, their URL is wrong.

$sql = "(SELECT postsID as postsID, postsSubject AS postsSubject, postsTimestamp AS timestamp
                FROM   posts
                WHERE  postsCategory = '$id')
            UNION 
                (SELECT eventID as eventID, eventTitle as eventTitle, eventsTimestamp as timestamp
                FROM   events
                WHERE  eventLocation = '$id')
            ORDER BY timestamp DESC";

The information is being correctly displayed from both the events and posts table, but the results are appearing to ONLY come from the posts table.

For example, say I have the following info

postsID |  postsSubject |  postsTimestamp
  1            post             123

eventID |  eventTitle   | eventsTimestamp
  2           event            456

I have the following to display my results

   while($row = mysql_fetch_assoc($result)){
    ?>
        <tr><td><? echo '<a href="viewevent.php?eventID=' . $row['eventID'] . '">' . $row['eventTitle'] . '</a>' ; ?></td>
        <tr><td><? echo '<a href="viewpost.php?postID=' . $row['postsID'] . '">' . $row['postsSubject'] . '</a>' ; ?></td>
    <?  
        if(preg_match('/[0-9]/',$row['timestamp'])){        
            list($yyyy,$dd,$mm) = explode('-',$row['timestamp']);
                    $newDate = $dd."-".$mm."-".$yyyy;
            }
        ?>
            <td><center><? echo $newDate; ?></center></td></tr>
        <?
        }
        echo '</table>';
}

The output appears to be correct

post   123
event  456

However, both results link to the following (respectively)

viewpost.php?id = 1
viewpost.php?id = 2  //this should be viewevent.php

Answer 1

sql as below:

$sql = "(SELECT postsID as ids, postsSubject AS description, postsTimestamp AS timestamp,'p' as status
                FROM   posts
                WHERE  postsCategory = '$id')
            UNION 
                (SELECT eventID as ids, eventTitle as description, eventsTimestamp as timestamp, 'e' as status
                FROM   events
                WHERE  eventLocation = '$id')
            ORDER BY timestamp DESC";

when retrieving data,

while($row = mysql_fetch_assoc($result)){
     if ($row['status']=="e"){
    ?>
        <tr><td><? echo '<a href="viewevent.php?eventID=' . $row['ids'] . '">' . $row['description'] . '</a>' ; ?></td>
<? }else{?>
        <tr><td><? echo '<a href="viewpost.php?postID=' . $row['ids'] . '">' . $row['description'] . '</a>' ; ?></td>
<? } ?>
    <?  
        if(preg_match('/[0-9]/',$row['timestamp'])){        
            list($yyyy,$dd,$mm) = explode('-',$row['timestamp']);
                    $newDate = $dd."-".$mm."-".$yyyy;
            }
        ?>
            <td><center><? echo $newDate; ?></center></td></tr>
        <?
        }
        echo '</table>';
}
