Php 将$\请求值传递给Datatable Ajax脚本

我正在使用DataTables，希望将请求值传递给php脚本。 Firebug报告未定义的索引。 以下是PHP脚本：

  $sIndexColumn = "opportunity_acccount_id";
  $sTable = "opportunities_base";
  $sWhere = "opportunity_acccount_id = '$_REQUEST['account_id']'";

以下是初始化表的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"
                }
          });

欢迎使用任何指针。

试试这个，如果它不起作用，你能用

var\u dump（$sWhere）

和

var\u dump（$sQuery）

我能弄明白。 目标是在Ajax请求中传递一个初始化DataTable的变量，这样我就只能显示与传递的帐户ID相关的结果。 以下是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"
        }

  });

希望这能帮助其他人

谢谢。

您的帐户id来自哪里？@Charkan帐户id在url中。好的，那么将请求值传递到php脚本是什么意思，是您的帐户id吗？如果是这样，并且它在您的url上，那么您无事可做。因此，我添加了fnServerParams（），它允许我发布其他参数。查询现在看起来不错，但数据未按要求进行筛选。有什么想法吗？你能给我们，你的php代码，这将使查询？
