Php 排序、分页、搜索jQuery数据表搜索端处理不'；行不通

我使用PHP+jQuery datatable服务器处理代码，能够在表中列出数据（通过JSON），但排序、分页和搜索不起作用。它在加载时加载表中的所有数据，并且请求/响应对于排序列、搜索任何数据和分页编号都是相同的

客户端：

$(".machines-data").dataTable({

                aLengthMenu: [ [5, 10, 25, 50, 100, 150, "-1"], [5, 10, 25, 50, 100, 150, "All"] ],
                iDisplayLength: 5,
                searching: true,
                "aaSorting": [],
                columnDefs: [ { orderable: true } ],
                "bServerSide": true,
                "processing": true,
                "serverSide": true,

                "ajax": { "url": "/machines/server.php", "type": "POST", "dataType": "json", "cache": false },

                    "aoColumnDefs": [
            { "data": "id" },
            { "data": "ip" },
            { "data": "machine" },
            { "data": "status" }
        ]

            });

JSON响应：

{"sEcho":0,"iTotalRecords":"45","iTotalDisplayRecords":"45","aaData":[["1","xx.yy.xx.yy","machine1","Completed"],[["1","xx.yy.xx.yy","machine2","Completed"]] .. 45 rows}

服务器端：

<?php

ignore_user_abort(true);

if($_POST) {

    $aColumns = array( 'id', 'ip', 'machine','status' );

    $sIndexColumn = "id";

    $sTable = "1_machines";

    $gaSql['user']       = "root";
    $gaSql['password']   = "pwd";

    $gaSql['server']     = "localhost";

    function fatal_error ( $sErrorMessage = '' )
    {
        header( $_SERVER['SERVER_PROTOCOL'] .' 500 Internal Server Error' );
        die( $sErrorMessage );
    }

    if ( ! $gaSql['link'] = mysql_pconnect( $gaSql['server'], $gaSql['user'], $gaSql['password']  ) )
    {
        fatal_error( 'Could not open connection to server' );
    }

    if ( ! mysql_select_db( $gaSql['db'], $gaSql['link'] ) )
    {
        fatal_error( 'Could not select database ' );
    }

    $sLimit = "";
    if ( isset( $_GET['iDisplayStart'] ) && $_GET['iDisplayLength'] != '-1' )

        $sLimit = "LIMIT ".intval( $_GET['iDisplayStart'] ).", ".
            intval( $_GET['iDisplayLength'] );
    }

    $sOrder = "";
    if ( isset( $_GET['iSortCol_0'] ) )

        $sOrder = "ORDER BY  ";
        for ( $i=0 ; $i<intval( $_GET['iSortingCols'] ) ; $i++ )
        {
            if ( $_GET[ 'bSortable_'.intval($_GET['iSortCol_'.$i]) ] == "true" )

                    ($_GET['sSortDir_'.$i]==='asc' ? 'asc' : 'desc') .", ";
            }
        }

        $sOrder = substr_replace( $sOrder, "", -2 );
        if ( $sOrder == "ORDER BY" )
        {
            $sOrder = "";
        }
    }

    $sWhere = "";
    if ( isset($_GET['sSearch']) && $_GET['sSearch'] != "" )
    {
        $sWhere = "WHERE (";

        }
        $sWhere = substr_replace( $sWhere, "", -3 );

        }
    }


    $sQuery = "

        FROM   $sTable
        $sWhere
        $sOrder
        $sLimit
        ";
    $rResult = mysql_query( $sQuery, $gaSql['link'] ) or fatal_error( 'MySQL Error: ' . mysql_errno() );

    $sQuery = "

    ";
    $rResultFilterTotal = mysql_query( $sQuery, $gaSql['link'] ) or fatal_error( 'MySQL Error: ' . mysql_errno() );
    $aResultFilterTotal = mysql_fetch_array($rResultFilterTotal);
    $iFilteredTotal = $aResultFilterTotal[0];

    $sQuery = "

最后，我很高兴我解决了这个问题，问题在于ajax数据发布和服务器处理。使用datatable+php服务器端处理php代码，客户端处理类似以下内容：

$(".machines-data").dataTable({

    aLengthMenu: [ [5, 10, 25, 50, 100, 150, "-1"], [5, 10, 25, 50, 100, 150, "All"] ],
    iDisplayLength: 5,
    searching: true,
    "aaSorting": [],
    columnDefs: [ { orderable: true } ],
    "sPaginationType": "full_numbers",
    "bDestroy": true,

    "bProcessing": true,                
    "serverSide": true,
    "sAjaxSource": "aLengthMenu: [ [5, 10, 25, 50, 100, 150, "-1"], [5, 10, 25, 50, 100, 150, "All"] ],
    iDisplayLength: 5,
    searching: true,
    "aaSorting": [],
    columnDefs: [ { orderable: true } ],
    "sPaginationType": "full_numbers",
    "bDestroy": true,

    "bProcessing": true,                
    "serverSide": true,
    "sAjaxSource": "/machines/server.php",

});

我也有同样的问题，在我的例子中，我使用的是参数“ajax”而不是“sAjaxSource”

为了解决这个问题，我现在使用“sAjaxSource”将datatable插件应用到我的表中
您的AJAX操作被调用并响应时没有错误吗？您是否已检查浏览器的网络监视器以实时观看此操作？你检查过你的JavaScript控制台吗？是的，哈弗。没有js错误，即使JSON响应像我提到的那样很好，但排序、分页和搜索都会给出相同的响应，但问题是除了在表中显示数据（这也不符合iDisplayLength）。您使用的是哪个版本的datatables？datatables 1.10.6几乎是最新的。将datatable更新为1.10.7，但运气不佳。我猜这个版本和它无关，因为它几乎是最新的。谁能帮我看看吗？
