Delete records where checkbox are ticked on a list

Hi,

I used this code that someone had asked earlier. It works perfectly, except that after i hit delete, nothing happens. in other words the view is not refreshed. Only when i go back to the page or refresh i can see the items have been deleted. Here is the code that i used:


<?php if(isset($_SESSION["username"]))
{            
     // start -> delete any valid checked rows
     if ( isset ( $_POST['option'] ) )
     {
          $temp = array ();
          foreach ( $_POST['option'] AS $id )
          {
               $id = intval ( $id );
               if ( $id > 0 )
               {
                    $temp[] = 'listingid = ' . $id;
               }
          }
          if ( ! empty ( $temp ) )
          {
               $sql = "DELETE FROM listings WHERE " . implode ( ' OR ', $temp );
               mysql_query ( $sql );
               unset ( $id );
                    
          }
          unset ( $temp );
     }
     // end -> delete any valid checked rows
            
// Table header.
echo' <form name="form1" method="post" action='.$_SERVER["PHP_SELF"];
echo '><table align="center" cellspacing="0" cellpadding="5" width="100%" class="gridtable">
<tr class="header" align="left">
      <td align="center" class="editanddelete" width="5%" valign="top">Edit</td>
      <td align="center" class="editanddelete" width="5%" valign="top">Delete</td>
      <td align="left" width="30%" valign="top"><a href="' . $link1 . '" class="gridheader">Title</a>' . $sortimg1 . '</td>
      <td align="left" width="40%" valign="top"><a href="' . $link2 . '" class="gridheader">Description</a>' . $sortimg2 . '</td>
      <td align="left" width="15%" valign="top"><a href="' . $link3 . '" class="gridheader">Price</a>' . $sortimg3 . '</td>
      <td align="left" width="5%" valign="top"><a href="' . $link4 . '" class="gridheader">Display</a>' . $sortimg4 . '</td>
</tr>
';
            
// Fetch and print all the records.
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
      echo '<tr>
            td align="left">' . $row[edit] . '</td>
            <td align="center"><input type="checkbox" name="option[]" value="' . intval( $row['listingid'] ) . '"</td>
            <td align="left">' . $row['title'] . '</td>
            <td align="left">' . $row['description'] . '</td>
            <td align="left">' . $row['price'] . '</td>
            <td align="left">' . $row['display'] . '</td>
      </tr>
      ';
}
            echo '</table><p><input type="submit" value="Delete Checked" class="button" /></p></form>'; // Close the table.

            mysql_free_result ($result); // Free up the resources.      
      
      } else { // If there are no registered users.
            echo '<span class="darkbluebig">There are currently no listings.</span>';
      }
      mysql_close(); // Close the database connection.
                        }
                        else {
                        echo '<span class="content"><br><br><br><br><br><br><p align="center">You are not logged in.<br><br>To login click <a href="../login.php">here</a>.</p></span>';
            }

Hi stevegingell,

Am I missing where you define $result to do: (I assume you left out some php where you setup your connection)
$row = mysql_fetch_array($result, MYSQL_ASSOC)

It is important to know when $result was defined,
if it was before you DELETED the rows then there is your problem, it still has the deleted rows.

Hi Joe,

Yes I have defined $result earlier in my code..heres a snippet from where its coming:

      $query = "SELECT customers.*, Listings.* FROM customers INNER JOIN listings ON customers.customerid =  listings.customerid WHERE customers.customerid = " .$_SESSION['customerid']. " ORDER BY listings.$order_by LIMIT $start, $display";
      $result = @mysql_query ($query); // Run the query.
      $num = mysql_num_rows ($result); // How many listings are there?

Like I said before make sure that is AFTER your:
     // end -> delete any valid checked rows

If it was before that point then it will still have the rows which you will "later" delete.
So make sure your query is AFTER that point and it should work just fine.

<td align="center"><input type="checkbox" name="option[]" value="' . intval( $row['listingid'] ) . '"</td>  <--------
 you left out somethings in the row, the checkbox control is not form properly.

it should be like below --->
<td align="center"><input type="checkbox" name="option[]" value="' . intval( $row['listingid'] ) . '" /></td>
