Question

我在数据库中有两个表（MySql），一个用于国家名称，另一个用于用户。现在，当某个用户被添加到他/她所在的网站中时，他们很好。但是由于用户数据库增长到2,000个用户，我需要强制更改为服务器端数据表以显示所有用户脚本强制冻结屏幕或网站。现在我看不到每个用户的国家名称，只有id ...所以我的问题是什么需要添加或更改以查看国家/地区名称而不是ID。

我关注这些帖子：

server-side

以下是我的数据库：

|----------USERS-------------|
|---id-----------int---------|
|---nombres---varchar(150)---| is the user name
|---fnac-------datetime------| is the birthday
|---direccion----text--------| is the address
|---paisid--------int(3)-----| is the country id
|---foto-------varchar(50)---| is the user photo
|----------------------------|

|-----------PAISES-----------|
|---id---------int(11)-------| is the country id
|---paises---varchar(100)----| is the country name
|----------------------------|

这里是我的代码（现在我不使用它，因为我不知道我需要在哪里插入它）：

<?php $query = "SELECT U.paisid, P.pais,
(SELECT pais FROM PAISES WHERE id = paisid)
AS pais
FROM USERS U
INNER JOIN PAISES P
ON  U.paisid = P.id";
$stmt = $conn->prepare( $query );   
$stmt->execute();
$rows = $stmt->fetchAll();
foreach( $rows as $row )
{ ?><?php echo $row['pais']; ?><?php } ?>

JS：

$('#userTabla').dataTable( {
    "bProcessing": true,
    "bServerSide": true,
    "sDom": "<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span12'i><'span12 center'p>>",
    "sAjaxSource": "includes/server_process.php",
    "aoColumns": [
        { "mData": "id" },
        { "mData": "nombres" },
        { "mData": "paisid" },
        {
            "mData": null,
            "sClass": "center",
            "sDefaultContent": "",
            "fnRender": function (o) {
            return '<a href="perfil.php?id=' + o.aData[0] + '" class="btn btn-success"><i class="icon-user icon-white"></i> Ver perfil</a> <a href="editar.php?id=' + o.aData[0] + '" class="btn btn-info"><i class="icon-edit icon-white"></i> Editar</a> <a id="' + o.aData[0] + '" class="btn btn-danger" href="#"><i class="icon-trash icon-white"></i> Borrar</a>'
        },
        "aTargets": [3]
        }
    ],
    "sPaginationType": "bootstrap",
    "oLanguage": {
    "sLengthMenu": "_MENU_ registros por pag"
    }
});

server_process.php（我更改示例数据的部分）

$aColumns = array( 'id', 'nombres', 'paisid');

/* Indexed column (used for fast and accurate table cardinality) */
$sIndexColumn = "id";

/* DB table to use */
$sTable = "USERS";

/* Database connection information */
$gaSql['user']       = "dbuser";
$gaSql['password']   = "XXXXXX";
$gaSql['db']         = "dbmega";
$gaSql['server']     = "localhost";

Answer 1

 <?php 
$query = "SELECT USERS.* , PAISES.`paises` as countryName
FROM USERS 
INNER JOIN PAISES 
ON  paisid = id";

$stmt = $conn->prepare( $query );   
$stmt->execute();
$rows = $stmt->fetchAll();

 $returnArray = array();
foreach( $rows as $row )
{ 
returnArray[] = array($row['id'],$row['nombres'],$row['countryName']);
}

请将paisid类型更改为int

var myDataTable = $('#userTabla').dataTable( {
    "bProcessing": true,
    "bServerSide": true,
    "sDom": "<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span12'i><'span12  center'p>>",
    "sAjaxSource": "includes/server_process.php",
    "aoColumns": [
        { "mData": "id" },
        { "mData": "nombres" },
        { "mData": "paisid" },
         {
           "mData": null,
           "sClass": "center",
           "sDefaultContent": "",
           "fnRender": function (o) {
           return '<a href="perfil.php?id=' + o.aData[0] + '" class="btn btn-success"><i class="icon-user icon-white"></i> Ver perfil</a> <a href="editar.php?id=' + o.aData[0] + '" class="btn btn-info"><i class="icon-edit icon-white"></i> Editar</a> <a id="' + o.aData[0] + '" class="btn btn-danger" href="#"><i class="icon-trash icon-white"></i> Borrar</a>'
         },
         "aTargets": [3]
        }
    ],
    "sPaginationType": "bootstrap",
    "oLanguage": {
    "sLengthMenu": "_MENU_ registros por pag"
    }
});

myDataTable.fnAddData( <? echo json_encode(returnArray[]); ?>);

在DataTable Server Side中显示名称行而不是ID
