Question

在这个代码过滤器中，搜索和分页无法正常运行我已经尝试过但是它没有用，所以请检查代码给我任何解决方案或任何有关此查询的参考。即使任何与此代码文件或文档相关的内容，对我来说都有助于实现这一概念

And also i need to Join two tables as given below.

表1

表2

Answer 1

我这样做：

$('#datatable_emp_details').dataTable({
    "sServerMethod": "POST", 
    "bProcessing": true,
    "bServerSide": true,
    "sAjaxSource": "get_data.php"
});

get_data.php：

<?php
$mongo      = new MongoClient();
$database   = $mongo->selectDb('dbtest');
$collection = $database->selectCollection('empDetails');
$skip       = (int)$_REQUEST['iDisplayStart'];
$limit      = (int)$_REQUEST['iDisplayLength'];
$search     = $_REQUEST['sSearch'];
$sortIndex  = $_REQUEST['iSortCol_0'];

$sortArray  = array('emp_id', 'first_name', 'last_name', 'position', 'email', 'office', 'start_date', 'age', 'salary', 'projects'
);
$sortByCol  = $sortArray[$sortIndex];
$sortTypeTxt= $_REQUEST['sSortDir_0'];  // asc/desc
$sortType = -1;
if( $sortTypeTxt == 'asc' )
{
    $sortType = 1;
}
if( $search != '' )
{
    $condtion = array(
                    '$or' => array(
                        array('emp_id'    => $search),
                        array('first_name'=> new MongoRegex('/'. $search .'/i')),   // i for case insensitive
                        array('last_name' => new MongoRegex('/'. $search .'/i')),
                        array('position'  => new MongoRegex('/'. $search .'/i')),
                        array('email'     => new MongoRegex('/'. $search .'/i')),
                        array('office'    => new MongoRegex('/'. $search .'/i')),
                        array('start_date'=> new MongoRegex('/'. $search .'/i')),

    $resultSet =   $collection->find($condtion)->limit($limit)->skip($skip)->sort(array($sortByCol => $sortType));
}
else
{
    $resultSet  = $collection->find()->limit($limit)->skip($skip)->sort(array($sortByCol => $sortType))->sort(array($sortByCol => $sortType));
}
$data = array();
if( count( $resultSet ) > 0 )

            10 => '<a href="javascript:void(0);" class="edit_emp" id="'. $item['emp_id'] .'">Edit</a> | <a href="javascript:void(0);" class="delete_emp" id="'. $item['emp_id'] .'">Delete</a>'
        );
