伙计们,我运气不好…我试了又试。包括下面的代码。我在Dreamweaver做这件事,这就是有趣的代码。这是编辑页。我成功地将“bet_id”值从第1页解析到此页。它根据从第1页解析的值,用正确的“bet_id”和“category_id”值填充表单字段。当我更新表单中的值时会出现问题。如果我更新“category_id”值并单击“更新下注”按钮,则脚本不会更新数据库中的下注记录。非常感谢您的帮助。

mysql_select_db($database_punters_c, $punters_c);

$query_Recordset1 = "SELECT bet_id, punter_id,category_id FROM betslip where bet_id =".intval($_REQUEST['bet_id']);

$Recordset1 = mysql_query($query_Recordset1, $punters_c) or die(mysql_error());

$row_Recordset1 = mysql_fetch_assoc($Recordset1);

$totalRows_Recordset1 = mysql_num_rows($Recordset1);

##the below function removes dodgy field values

function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")

{

$theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue;

switch ($theType) {

case "text":

$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";

$theValue = ($theValue != "") ? intval($theValue) : "NULL";
