Dupliker en post i MySQL

Jeg fandt endelig denne kode. Jeg er sikker på, at det vil hjælpe folk i fremtiden. Så her er det.

function DuplicateMySQLRecord ($table, $id_field, $id) {
  // load the original record into an array
  $result = mysql_query("SELECT * FROM {$table} WHERE {$id_field}={$id}");
  $original_record = mysql_fetch_assoc($result);

  // insert the new record and get the new auto_increment id
  mysql_query("INSERT INTO {$table} (`{$id_field}`) VALUES (NULL)");
  $newid = mysql_insert_id();

  // generate the query to update the new record with the previous values
  $query = "UPDATE {$table} SET ";
  foreach ($original_record as $key => $value) {
    if ($key != $id_field) {
        $query .= '`'.$key.'` = "'.str_replace('"','\"',$value).'", ';
    }
  }
  $query = substr($query,0,strlen($query)-2); # lop off the extra trailing comma
  $query .= " WHERE {$id_field}={$newid}";
  mysql_query($query);

  // return the new id
  return $newid;
}
