【问题描述】：
hy，我在使用 PHP 和 oracle 数据库设置分页时遇到问题，该页面仅显示第一页值。当我单击下一步按钮时，页面从第 1 页更改为第 2 页、第 3 页等，但值仍然与第 1 页相同。我不知道，我不知道如何修复此错误..
这是我设置记录集的代码..
<?php
// Set up recordset
define("ewSqlSelectCount", "SELECT count(*) count FROM sid_mst_dealer", true);
$sSql_count = BuildSqlang(ewSqlSelectCount, ewSqlWhere, ewSqlGroupBy, ewSqlHaving, ewSqlOrderBy, $sDbWhere, $sOrderBy);
//echo "$sSql_count" . "<br/ >";
$rs_count = moi_query($sSql_count , $conn) or die("Failed to execute query at line " . __LINE__ . ": " . moi_error($conn) . '<br>SQL: ' . $sSql);
//echo $rs_count;
oci_execute($rs_count);
$nTotalRecs = oci_fetch_array($rs_count);
$nTotalRecs = $nTotalRecs['COUNT'];
$rs = moi_query($sSql, $conn) or die("Failed to execute query at line " . __LINE__ . ": " . moi_error($conn) . '<br>SQL: ' . $sSql);
//echo $rs;
oci_execute($rs);
if ($nDisplayRecs <= 0) { // Display all records
$nDisplayRecs = $nTotalRecs;
}
$nStartRec = 1;
SetUpStartRec(); // Set up start record position
?>
这是函数..
function SetUpStartRec()
{
// Check for a START parameter
global $nStartRec;
global $nDisplayRecs;
global $nTotalRecs;
if (strlen($_GET[ewTblStartRec]) > 0)
{
$nStartRec = $_GET[ewTblStartRec];
$_SESSION[ewSessionTblStartRec] = $nStartRec;
} elseif (strlen($_GET["pageno"]) > 0)
{
$nPageNo = $_GET["pageno"];
if (is_numeric($nPageNo))
{
$nStartRec = ($nPageNo-1)*$nDisplayRecs+1;
if ($nStartRec <= 0)
{
// echo 'jangan ke sini';
$nStartRec = 1;
}
elseif ($nStartRec >= (($nTotalRecs-1)/$nDisplayRecs)*$nDisplayRecs+1)
{
$nStartRec = (($nTotalRecs-1)/$nDisplayRecs)*$nDisplayRecs+1;
}
$_SESSION[ewSessionTblStartRec] = $nStartRec;
}
else
{
$nStartRec = $_SESSION[ewSessionTblStartRec];
if (!(is_numeric($nStartRec)) || ($nStartRec == ""))
{
$nStartRec = 1; // Reset start record counter
$_SESSION[ewSessionTblStartRec] = $nStartRec;
}
}
}
else
{
$nStartRec = @$_SESSION[ewSessionTblStartRec];
if (!(is_numeric($nStartRec)) || ($nStartRec == "")) {
$nStartRec = 1; // Reset start record counter
$_SESSION[ewSessionTblStartRec] = $nStartRec;
}
}
}
这是查询
<?php
define("ewTblVar", "sid_mst_dealer", true);
define("ewTblRecPerPage", "RecPerPage", true);
define("ewSessionTblRecPerPage", "sid_mst_dealer_RecPerPage", true);
define("ewTblStartRec", "start", true);
define("ewSessionTblStartRec", "sid_mst_dealer_start", true);
define("ewTblShowMaster", "showmaster", true);
define("ewSessionTblMasterKey", "sid_mst_dealer_MasterKey", true);
define("ewSessionTblMasterWhere", "sid_mst_dealer_MasterWhere", true);
define("ewSessionTblDetailWhere", "sid_mst_dealer_DetailWhere", true);
define("ewSessionTblAdvSrch", "sid_mst_dealer_AdvSrch", true);
define("ewTblBasicSrch", "psearch", true);
define("ewSessionTblBasicSrch", "sid_mst_dealer_psearch", true);
define("ewTblBasicSrchType", "psearchtype", true);
define("ewSessionTblBasicSrchType", "sid_mst_dealer_psearchtype", true);
define("ewSessionTblSearchWhere", "sid_mst_dealer_SearchWhere", true);
define("ewSessionTblSort", "sid_mst_dealer_Sort", true);
define("ewSessionTblOrderBy", "sid_mst_dealer_OrderBy", true);
define("ewSessionTblKey", "sid_mst_dealer_Key", true);
// Table level SQL
define("ewSqlSelect", "SELECT * FROM sid_mst_dealer", true);
if($_REQUEST[dealer_id]==""){
if($_REQUEST[x_status]!=""){
define("ewSqlWhere", " active_flag ='".$_REQUEST[x_status]."'", true);
}else{
define("ewSqlWhere", "active_flag='0'", true);
}
}else{
define("ewSqlWhere", "", true);
}
define("ewSqlGroupBy", "", true);
define("ewSqlHaving", "", true);
define("ewSqlOrderBy", "", true);
define("ewSqlOrderBySessions", "", true);
define("ewSqlKeyWhere", "dealer_id = '@dealer_id'", true);
define("ewSqlUserIDFilter", "", true);
?>
我真的需要帮助来解决这个问题。谢谢你：D
【问题讨论】：
-
该代码很难阅读 - 是否有一个
limit子句潜伏在那里？ -
@RamRaider 我也有同样的问题，这不是我的代码，我只是为此做增强。所以我对此一无所知..真的很困惑..我试图理解这一点，但这很难。
