YADCF + Datatables服务器端用PHP填充Select [英] YADCF + Datatables Server Side Populate Select with Php

问题描述

我从字面上搜索了提及该论点的每一页"，但似乎无法弄清楚这一点 我正在使用Yadcf，ajax源，server_side.php和ssp.class.php的数据表

I literally have searched Every Single Page that mentions the argument, but cant seem to figure this one out I am using Datatables with Yadcf , ajax source, server_side.php and ssp.class.php

现在，我想用所有数据(不仅是当前页面)填充选择过滤器， 我阅读并看到了yadcf展示柜--> yadcf-showcase.appspot.com/server_side_source.html ，唯一提到的是JQuery(java)部分，用于填充 yadcf_data_n

Now i want to populate the select filters with All the data, not just the current page, I read and saw the yadcf showcase --> yadcf-showcase.appspot.com/server_side_source.html that the only mention is a JQuery (java) part to populate the yadcf_data_n

但是找不到使用server_side.php和ssp.class.php来检索数据的单个示例来做同样的事情.

But cant find one single example to do the same using the server_side.php and ssp.class.php to retrieve the data.

我(以及我在很多其他人的眼中看到的)将拥有一个关于如何归档此文件的实用例子

I (and from what i saw around a lot of other people) would be really great full to have a piratical example on how to archive this

我的数据表代码是:

  var oTable2;
  oTable2 = $('#example2').DataTable({
            "responsive": true,
            "processing": true,
            select: true,
            "serverSide":true,
            stateSave: true,
            "ajax": {
               "type" : "GET",
               "url":  "leadsdata.php",
               "data" :  function ( d ) {
                d.var1=var1;
                   }

            },
            "columns": [{
                "data":"test",
                "mRender": function ( client_id, type, full )  {
                return  '<a href="clickme.php?id='+Base64.encode(client_id)+'"> GO</a>';
                }
        },{
                "data": 1
        },{
                "data": 2
        },{
                "data": 3
        },{
                "data": 4               
        },{
                "data": 5
        },{
                "data": 6

  }],
            "language": {
               "infoFiltered": ".",
               "info": "_START_ : _END_ nga _TOTAL_ nominativ"
             }

   });

    yadcf.init(oTable2, [{
            column_number: 1,
                  filter_type: "text",
                  filter_delay: 200
            }, {
            column_number: 2,
                  filter_type: "text",
                  filter_delay: 200
            }, {
            column_number: 3
            }, {
            column_number: 4,
                filter_type: "text",
                filter_delay: 200   
            }, {
            column_number: 5

            }, {
            column_number: 6

            }]);

    });

并使用默认的server_side.php 点击此处显示

和默认的ssp.class.php 点击此处显示

欢迎任何示例代码说明如何从此设置填充yadcf_data_n#

感谢vedmack(YADCF)作者的帮助，我找到了完美的解决方案:

Thanks for the help of vedmack (YADCF) author i found the perfect solution:

修改来自的零件:

    echo json_encode(
    SSP::simple( $_GET, $sql_details, $table, $primaryKey, $columns )
);

收件人:

$data=SSP::simple( $_GET, $sql_details, $table, $primaryKey, $columns, $joinQuery, $extraWhere );

$db = SSP::sql_connect( $sql_details );
$stmt3 = $db->prepare( 'SELECT DISTINCT(value) FROM esito' );
$stmt3->execute();
$data['yadcf_data_3'] = $stmt3->fetchAll(PDO::FETCH_COLUMN, 0);

$stmt5 = $db->prepare( 'SELECT DISTINCT(value2) FROM table' );
$stmt5->execute();
$data['yadcf_data_5'] = $stmt5->fetchAll(PDO::FETCH_COLUMN, 0);

$stmt6 = $db->prepare( 'SELECT DISTINCT(value3) FROM table' );
$stmt6->execute();
$data['yadcf_data_6'] = $stmt6->fetchAll(PDO::FETCH_COLUMN, 0);


echo json_encode($data);

因此，我们对每个选择字段进行自定义查询(在我的情况下，我有3个) 并重新包含$ db，因为我的ssp.class.php位于其他文件中

So we make a custom query for each select field we have (In my case i had 3) And re-include the $db since i have my ssp.class.php in different file
