Salve a tutti
ho realizzato un db (al momento solo una lista) di articoli, ci ho messo dentro anche una funzione di delete, ma non funge e non riesco a capire dove sta il problema:


Codice PHP:
<?php 
         $dbm 
= new dbmanager();
          if (
$dbm->open()) {
           if (
$rs $dbm->query("SELECT * FROM articoli INNER JOIN stato ON 
articoli.idstato=stato.id INNER JOIN argomento ON articoli.idargomento=argomento.id"
)) {
      
?>
      <form action="pubblicazioni.php" method="post">
        <table summary="" width="99%" cellspacing="2"
        cellpadding="2" border="1" align="center">
          <thead>
            <tr>
              <th></th>
              <th width="42%">
                <font color="#FE9900">Titolo</font>
              </th>
              <th width="27%">
                <font color="#FE9900">Autori</font>
              </th>
              <th width="87%">
                <font color="#FE9900">Stato</font>
              </th>
              <th width="9%">
                <font color="#FE9900">Data</font>
              </th>
              <th width="8%">
                <font color="#FE9900">Rivista</font>
              </th>
              <th width="5%">
                <font color="#FE9900">Argomento</font>
              </th>
            </tr>
          </thead>
                <?php 
                       
while ($row $dbm->fetch($rs)) {
                          echo 
'<tr><td align="justify">'
                          
.'<input type="checkbox" name="da_cancellare[]" value="'
                                                    
.$row['id'].'" />'
                          
.'</td><td align="center">'.$row['titolo']
                          .
'</td><td align="center">'.$row['autore']
                          .
'</td><td align="center">'.$row['data']
                          .
'</td><td align="center">'.$row['tipo']
                          .
'</td><td align="center">'.$row['supporto']
                          .
'</td><td align="center">'.$row['campo']
                          .
'</td></tr>';
                          }
       
?>
        </table>
             <?php
                      
} else {
                      echo 
"Non ho trovato nessun articolo.";
                      }
                      }else{
                      echo 
"Si e' verificato un errore durante la connessione con il database.";
                      }
       
?>
             

             <?php 
          
if ($_SERVER['REQUEST_METHOD']=='POST') {
            
$id_list $_REQUEST['da_cancellare'];
            foreach ( 
$id_list as $id ) {
             
$dbm->query("DELETE FROM 'articoli' WHERE id='$id'");
            }
                    
$dbm->close();
          }
       
?>
        <input type="submit" name="elimina" value="Elimina Articolo" alt=
        "Elimina" title="Elimina elemento" src="add.png" />
      </form>
