    文章类别管理页面与文章管理页面类似 不同的是更新的表为types 具体代码如下所示     <?php require_once( Connections/conn php ); ?>     <?php     //用于进行格式转换的函数     function GetSQLValueString($theValue $theType $theDefinedValue =     $theNotDefinedValue = )     {       $theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue;       switch ($theType) {         case text :           $theValue = ($theValue != ) ? $theValue : NULL ;           break;           case long :         case int :           $theValue = ($theValue != ) ? intval($theValue) : NULL ;           break;         case double :           $theValue = ($theValue != ) ? doubleval($theValue) : NULL ;           break;         case date :           $theValue = ($theValue != ) ? $theValue : NULL ;           break;         case defined :           $theValue = ($theValue != ) ? $theDefinedValue : $theNotDefinedValue;           break;       }       return $theValue;     }     //插入操作     if ((isset($_POST[ MM_insert ])) && ($_POST[ MM_insert ] == form ))     {     //  $insertSQL = sprintf( INSERT INTO types (type_name) VALUES (%s)     //                       GetSQLValueString($_POST[ type_name ] text ));       $insertSQL = sprintf( INSERT INTO types (type_id type_name last_upt_id)     SELECT MAX(type_id)+ %s %s FROM types                              GetSQLValueString($_POST[ type_name ] text )                              GetSQLValueString($_SESSION[ MM_Username ] text ));                                 mysql_select_db($database_conn $conn);       $Result = mysql_query($insertSQL $conn) or die(mysql_error());       echo <script>alert( 新类别创建成功！ );</script> ;     }     //更新操作     if ((isset($_POST[ MM_update ])) && ($_POST[ MM_update ] == form ))     {       //验证新type_id的有效性       $validateSQL = sprintf( SELECT type_name FROM types WHERE type_id=%s                            GetSQLValueString($_POST[ new_type_id ] int ));       mysql_select_db($database_conn $conn);       $rs_validate_merge = mysql_query($validateSQL $conn) or die(mysql_error());       $row_rs_validate_merge = mysql_fetch_assoc($rs_validate_merge);
