My sql query is giving me a wrong result

[prolife]

hello people my code is displaying the last result instead of the exact result i requested for.

Here is my code

 

 

<table width="800" height="40" align="center">
               <form action="admin-edit-room.php" method="post">
              <?php
                  $object->database();
                  $object->set_sqlstr(htmlspecialchars( "SELECT `cat`.*,`rooms`.* FROM `cat`,`rooms` WHERE `cat`.`id` = `rooms`.`catid`  ") );
                 // $object->set_sqlstr("SELECT * FROM `rooms` " );
                  $object->querydata();
                  $num = $object->no_rows;
                  if($num=0){echo "Your inbox is empty";}
                  $i=1;
                  while($object->data[0]!= ""){  
                      $class = (($i%2)==0) ? 'td_colour1' : 'td_colour2';
                      echo'<tr class="'.$class.'">';
                        echo'<td width="50" height="10" class="admin-details-form" align="left">'. $object->data['room-name'] .'</td>';
                        echo'<td width="200" height="10" class="admin-details-form" align="left">'. $object->data['room-descript'] .'</td>';
                        echo'<td width="200" height="10" class="admin-details-form" align="left"><input type="hidden" name="roomid" value="'.$object->data['roomid'].'" />'.$object->data['catid'].'</td>';
                        echo'<td width="200" height="10" class="admin-details-form" align="left"><input type="hidden" name="catid" value="'.$object->data['catid'].'" /></td>';
                        echo'<td width="10" height="10" class="admin-details-form" align="center"><input type="submit" name="edit" value="Edit" /></td>';
                      echo'</tr>';
                      
                    $object->fetchdata();
                    $i++;
                }
              ?>   
               </form>
            </table>

 

Now the thing is i placed "roomid" inside an hidden field and submited it to the next  transaction page as you can see but instead of it submiting the specific id it keeps submiting the last roomid, please what could be the problem? thanks

$object->set_sqlstr(htmlspecialchars( "SELECT `cat`.*,`rooms`.* FROM `cat`,`rooms` WHERE `cat`.`id` = `rooms`.`catid`  ") );

There's no HTML in there. Don't use htmlspecialchars().

 

SELECT `cat`.*,`rooms`.* 

Don't SELECT * when you only want a couple columns. Specifically name the ones you want.

 

$object->no_rows

Is it really called "no_rows"? Not, like, "num_rows"?

 

if($num=0){

Not enough =s.

 

$object->data['room-name']

Is it really named with a hyphen? If so, that better be because the $object thing added it and not because your column is actually named "room-name".

 

it keeps submiting the last roomid

Are you sure that is what's happening? Have you verified that the HTML you've outputted has the wrong ID there?
