DW做的简单PHP管理
在这个页面,有二个行为按钮,一个是“修改”,一个是“删除”。
点“修改”,没有问题;如下图所示:
点“删除”后,跳转后的页面无数据记录,其实这时在浏览页面里已经看不到了。
按正常是跳转到正式的删除页面,然后点击对应记录条下面的删除按钮,才完成删除,这样才对啊?
问题是出在哪儿了呢?

删除的查询语句是怎样的
if ((isset($_GET['id'])) && ($_GET['id'] != "")) {
$deleteSQL = sprintf("DELETE FROM price WHERE id=%s",
GetSQLValueString($_GET['id'], "text"));
mysql_select_db($database_myconn, $myconn);
$Result1 = mysql_query($deleteSQL, $myconn) or die(mysql_error());
}
$colname_Recordset1 = "1";
if (isset($_GET['id'])) {
$colname_Recordset1 = (get_magic_quotes_gpc()) ? $_GET['id'] : addslashes($_GET['id']);
}
mysql_select_db($database_myconn, $myconn);
$query_Recordset1 = sprintf("SELECT * FROM price WHERE id = %s", $colname_Recordset1);
$Recordset1 = mysql_query($query_Recordset1, $myconn) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
if (isset($_GTE['id'])){
$query_Recordset1 = sprintf("SELECT * FROM price WHERE id = %s", $colname_Recordset1);
}else{
$query_Recordset1 = "SELECT * FROM price WHERE 1=1";
}
if (isset($_GTE['id'])){
$query_Recordset1 = sprintf("SELECT * FROM price WHERE id = %s", $colname_Recordset1);
}else{
$query_Recordset1 = "SELECT * FROM price WHERE 1=1";
}

大神,小弟还是没有看懂。
估计你是直接执行了删除代码了

qq吧 编辑页面:
