我正在使用DataTables，并希望将REQUEST值传递给php脚本。 Firebug报告未定义的索引。 这是PHP脚本：
$sIndexColumn = "opportunity_acccount_id";
$sTable = "opportunities_base";
$sWhere = "opportunity_acccount_id = '$_REQUEST['account_id']'";
这是初始化表格的JavaScript：
var oTable = $('#opportunities_table').dataTable( {
// "aoColumnDefs": [
// { "bSortable": false, "aTargets": [ 0 ] }
// ],
"aaSorting": [[0, 'asc']],
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "../includes/functions/opportunity_json.php",
"fnServerParams": function ( aoData ) {
aoData.push( { "name": "acct_id", "value": "3" } );
},
"aoColumns": [
{ "mData": "0" },
{ "mData": "2" },
//Begin actual rows
{ "mData": "6" },
{ "mData": "10" },
{ "mData": "12" },
{ "mData": "8" },
{ "mData": "4" },
],
"sDom": '<"dt-panelmenu clearfix"Tfr>t<"dt-panelfooter clearfix"ip>',
"oTableTools": {
"sSwfPath": "scripts/plugins/datatables/extensions/TableTools/swf/copy_csv_xls_pdf.swf"

});

试试这个，如果它不起作用，您可以使用var_dump($sWhere)和var_dump($sQuery)

答案 1 :(得分：0)
我能够弄清楚。 目标是在Ajax请求中传递一个初始化DataTable的变量，这样我只能显示与传递的帐户ID相关的结果。 这是Ajax请求：
var acct_id = $('#acct_id').val();
var oTable = $('#opportunities_table').dataTable( {
// "aoColumnDefs": [
// { "bSortable": false, "aTargets": [ 0 ] }
// ],
"aaSorting": [[0, 'asc']],
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "../includes/functions/opportunity_json.php",
"fnServerParams": function ( aoData ) {
aoData.push( {"name": "account_id", "value": acct_id} );
},
"aoColumns": [
{ "mData": "0" },
{ "mData": "2" },
//Begin actual rows
{ "mData": "6" },
{ "mData": "10" },
{ "mData": "12" },
{ "mData": "8" },
{ "mData": "4" },
],
"sDom": '<"dt-panelmenu clearfix"Tfr>t<"dt-panelfooter clearfix"ip>',
"oTableTools": {
"sSwfPath": "scripts/plugins/datatables/extensions/TableTools/swf/copy_csv_xls_pdf.swf"
}
});
这是PHP代码：
$account_id = $_REQUEST['account_id'];
if ( isset($account_id) && $account_id != "" ) {
if ($sWhere) $sWhere .= " AND opportunity_acccount_id=".mysqli_real_escape_string( $connection, $account_id );
else $sWhere = " WHERE opportunity_acccount_id=".mysqli_real_escape_string($connection, $account_id );
}
希望这会有所帮助。
谢谢。
