显示名称行而不是DataTable服务器端的ID

Question

我在数据库（MySql）中有两个表，一个是国家名称，另一个是用户。现在，当一些用户被添加到他/她选择的网站时，他/她是很好的。但是，由于用户数据库增长到2000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所在国家的名称，只有ID ......所以我的问题需要添加或更改以查看国家名称而不是ID。

我遵循这些帖子：

1. how-relating-two-tables-to-show-name-row-and-not-the-id-in-mysqlpdo
2. server-side

这里是我的数据库：

|----------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 
|----------------------------| 

这里我的代码（现在我不使用它因为我不知道我需要插入它的位置）：

个

<?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 } ?> 

的JS：（其中I改变示例数据部分）

$('#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" 
    } 
}); 

的server_process.php

$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']); 
} 

请变更paisid类型为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[]); ?>);
